Fam. DYSDERIDÆ. Ischnothyreus velox, Jackson. This curious little spider has again been sent to me during the past year from the Royal Gardens, Kew, where, in the warmer buildings, it appears to be quite domiciled, though no doubt originally introduced from some exotic region. Fam. DRASSIDE. Drassus pubescens, Thor. An adult male sent to me in July, 1908, from Whitchurch, near Stratford-on-Avon, by the Rev. J. A. Bloom. Prosthesima pedestris, C. L. Koch. A full grown example of this spider was sent to me from the New Forest, Hampshire, by Mr. H. Donisthorpe ; it was in the jaws of another spider. Xysticus robustus, Hahn. Noted further on p. 62 postea. Clubiona neglecta, Cambr. An adult male sent to me from Worcestershire by the Rev. J. H. Bloom. It is a rare spider, though widely distributed. Clubiona facilis, sp.n. Nearly allied to Clubiona holosericea, De Geer. A single example of the adult female sent to me from Shipley, Yorkshire, by Mr. R. P. Winter (see further note and description p. 68 postea). Fam. AGELENIDÆ. Cryphoeca incisa, Cambr. Two adult females, found in nests of Formica fusca, were kindly sent to me in May, 1909, by Mr. H. Donisthorpe, from Bradgate Park, Leicestershire. Cicurina cinerea, Panz. Adult and immature females found in nests of Lasius fuliginosus, Darenth Wood, in September, 1909, were sent to me by Mr. H. Donisthorpe. Tegenaria Derhamii, Scop. Dr. Oliver, of Bradford, Yorkshire, tells me that a female of this species (just dead) had lived under his care seven years in confinement; and another example five years. These are supposed by Dr. Oliver to have furnished instances of "Parthenogenesis," but the evidence did not appear to me conclusive on the point. Fam. THERIDIIDÆ. Theridion aulicum, Luc. Adults of both sexes of this rare and local spider were found in June, 1909, at the Sandbanks, near Poole, and also Morden Park, Bloxworth, by Dr. A. R. Jackson, and my son, Alfred E. Ll. Pickard-Cambridge. Leptyphantes patens, Cambr. The spider recorded (Proc. Dors. F. Club, Vol. XXVIII., p. 140, pl. A, figs. 20, 21), as the female of this species appears to be most probably that of Leptyphantes pallidus, Cambr. Porrhomma microphthalmum, Cambr. The spider recorded (Proc. Dors. F. Club, Vol. XXIX., p. 172) as Porrhomma Meadii, F.O.P., C., being synonymous with P. microphthalmum, should have been entered under the latter name. Hilaira excisa, Cambr. Numerous examples of both sexes received from the Rev. J. E. Hull from Northumberland in 1909. Hilaira uncata, Cambr. An adult female from Mr. D. R. P.-Beresfo:d, by whom it was found near the Ulster Canal, Ireland. ? Oreoneta Tmeticus, Cambr.) fortunata, Cambr. Porrhomma inerrans, Cambr., Proc. Dors. N.H. and A. Field Club, Vol. VI., p. 11 (male, not female). An adult male from Rev. R. J. Pickard-Cambridge, found on iron railings at Warmwell, May 29, 1909. Also two males in a similar situation, at Bloxworth Rectory, taken by Dr. A. R. Jackson and myself early in June, 1909. From a recent examination and comparison of types, it appears that the males of Porrhomma inerrans. Cambr., and O. fortunata, Cambr., are undoubtedly identical though the females are distinct. Mengea, F. O. P.-C. (Tmeticus, Cambr.), Warburtonii, Cambr. Tmeticus probabilis, Cambr., Proc. Dors. F. Club, XXIX., p. 195. T. probabilis, Cambr., is certainly a small variety of the female of M. Warburtonii with no sign of the usual dark chevrons on the upper side of the abdomen. An adult female of M. Warburtonii was received from Dr. A. R. Jackson, by whom it was found near Stamford Bridge, Cheshire, in September, 1909. Microneta innotabilis, Cambr. An adult male found by A. E. LI. Pickard-Cambridge among herbage in Berewood, near Bloxworth, July 2nd, 1909. Microneta passiva, Cambr. Adults of both sexes were received from the Rev. J. E. Hull, Northumberland, and from Mr. W. Falconer, near Huddersfield. The spider at first thought to be the female of M. passiva turns out to be that of M. saxatilis, Bl. For a figure of what is now considered to be M. passiva (female) see postea pl. A., figs. 4, 5, 6, cf. also Proc. Dors. N.H. and A.F. Club XXX., p. 105. Sintula fausta, Cambr. Both sexes, adult, were received from Northumberland from the Rev. J. E. Hull in 1909. Typhocrestus digitatus, Cambr. An adult female received from Mr. H. Donisthorpe, by whom it was found in an ant's nest (Formica fusca), Bradgate Park, Leicestershire, May, 1909. Diplocephalus picinus, Bl. Gongylidium morum, Cambr., Ann. Scottish Nat. Comparison of the type of G. morum with typical examples of D. picinus, Bl. (female), shows that these two spiders are identical. Genus HYPSELISTES, Sim., Hist. des Araignées, 2nd Ed., tom. I., p. 671. This genus was formed by M. Simon for a North American (New England) spider-Erigone (Entelecara) florens Camb. (Proc. Zool. Soc., London, 1875, p. 403, pl. xlvi., Fig. 10). Its chief generic distinction seems to be based upon the armature of the underside of the tibia and metatarsi of the legs, which appears to be a good distinction, though it is chiefly marked in the female, and in that sex most strongly on the anterior legs, while in the male it is not so remarkable.* Hypselistes florens, Cambr. Erigone florens, Cambr., Proc. Zool. Soc., Lond., 1875, p. 403, Pl. xlvi, Fig. 10. Both sexes adult were received lately from the Rev. J. E. Hull; these were found by Mr. Hull's nephew (Mr. H. H. Harrison) in swampy places on the ancient jet workings on Eston Moor, Cleveland, Yorkshire. The occurrence of this fine and very distinct species in Yorkshire is of great interest, as it has not been recorded in any locality until now since its record in 1875 in North America, where it appears to be an abundant form. It is new to the British fauna. Hypselistes Jacksonii, Cambr. Entelecara Jacksonii, Cambr., Proc. Dors. N.H. and A.F. Club, XXIII., 1902, pp. 24 and 23, Fig. 6. Taking the armature of the legs as generically distinctive, Entelecara Jacksonii, Cambr., should, I think, be removed to the genus Hypselistes, Sim. Others of the genus Entelecara show a somewhat analogous, though not similar, armature, while in one or two species the legs are normal. Further consideration seems necessary to determine the position of the different species of this now somewhat heterogeneous group. *M. Simon says, 1.c., simply "tibiis anticis subtus satis longis biseriatis instructi." All the legs, however, metatarsi as well as tibiæ, are more or less well-marked in respect of this armature. In Arachnides de France V., p. 617, M. Simon includes E. florens, Cambr., in the genus Nematognus, Sim., with the type of which, however, E. florens, Cambr., has only a somewhat similar general form of the male palpus, but no other good affinity. |
