The sternum is yellow, divided longitudinally by a well-defined and very distinct nearly black stripe. The abdomen is of an elongate oval form, and clothed with dull yellowish hairs ; the normal maculae on the fore part, as well as the ordinary angular bars, or chevrons, on the hinder part (which last are spotted with small black points), are well defined, and vary in colour from yellow to reddish yellow-brown; besides which there are various lines and spots of yellowish and white, the ground-colour being nearly black, and the whole forming an exceedingly pretty and variegated pattern ; the sides are yellowish, marked with short blackish spots and streaks ; and the underside is also yellow, marked with three broken blackish lines. An immature male and two adult females were found near Alexandria. It may be distinguished from all other European and Egyptian Spiders known to me by the yellow sternum bisected by a longitudinal black stripe. TROCHOSA DEPUNCTA, sp. n. Adult male, length 3| lines. This spider is very closely allied to T. picta, Hahn, but may be distinguished by its less distinct pattern and paler colours ; the structure also of the palpal organs is different. The whole of the underside also, except the sternum, is of a pale yellow colour without any markings, the sternum being blackish brown, with a yellow longitudinal line dividing the fore half; while the underside of T. picta is invariably (in m y experience) of a sooty black hue, and the annulation of the legs very strong and distinct. Possibly this Spider may be the Lycosa nilotica of Savigny ; but as there appears to be considerable doubt upon the point, I have thought it best to give it here as a distinct species. An adult male and two females were found near Alexandria. TROCHOSA PILIPES. Lycosa pilipes, Luc. Expl. en Algerie, p. 109, pl. ii. fig. 8. Numerous examples of both sexes of this Spider were found under stones on the damp sandy flats bordering the Nile in Upper Egypt; and I believe them to be identical with the Spider described and figured by H. Lucas (loc. cit.). It is very closely allied to examples of Trochosa lynx, Koch, received from Dr. L. Koch, but is, I think, decidedly of a different species. The numerous long erect bristles and hairs on the legs (and, in fact, on the whole Spider) are very characteristic. TROCHOSA VIRULENTA, sp. n. Adult male, length 6 lines; adult female, 7 lines. This Spider is nearly allied both to T. pilipes, Luc, and T. lynx, Koch, but may be distinguished by its larger size and bolder though very similar pattern on the abdomen. The palpi also of the male differ very perceptibly in their greater strength, their shorter cubital |
