41. — Steatoda sordidata, sp. n. 
Adult female : length 2| lines. 
In form and structure this spider resembles Steatoda nigrocincta. The eyes, however, 
are smaller and more closely grouped, and the line formed by two tore-centrals is longer than 
that formed by the hind-central pair. The whole of the fore part is of a dull dark-brow n 
colour, tinged with yellow. The abdomen is similar, but without the yellowish tinge ; a broa 
longitudinal median band, as well as a narrower, lateral, dentated one on each side, meeting 
round the fore extremity, are formed by white cretaceous spots ; and a similar line longitudi 
nally bisects the under side ; four small impressed black spots form a square (whose fore side 
is shortest) on the fore hall of the upper side.

Sab. — Examples of the female of this puzzling spider were found in Dr. Stoliczka s col 
lection, taken en route from Yarkand to Bursi, May 28th to June 17th, 1874. 
The difficulty of assigning to it its correct systematic place is very evident from the syno 
nyms above quoted. Mons. Eugene Simon has, however, lately suggested to me that it is 
nearly allied to Drepanodus obscurus, Menge, and, entirely agreeing with this, I have place 
it here in that genus. 
Genus — PEYCTJS, Cambr. 
The short broad form and very laterigrade appearance of the typical example of ||' lu 
genus led to the conjecture that it belonged to the family Thomisides ( vide O. P. Cambn ge, 
< On some new T Genera and Species of Araniedca,’ in Proc. Zool. Soc., 1870, p. 742, pi- x ’ 
fig. 9. Subsequent examination leads me to conclude that its proper place is in the 
Theridiides (not far from the genus Euryopis (Thor.), but certainly not among the Or i 
larice, as conjectured by Dr. T. Thorell (Syn. Eur. Spid., p. 600).

The cephalothorax is short, broad behind, and narrowing gradually forwards, but w 
much lateral constriction at the caput : this portion is large, bluff in front, consi 
elevated, rising gradually but quickly from the thorax. The clypeus rather excee s i .^ elJ t, 
half that of the facial space : it is round on the lower margin, and full and ratliei' from ^ 
projecting gradually from just beneath the front row of eyes. The colour of the 0 
thorax is a deep yellowish-brown, and behind each hind-lateral eye is a stron_,is ,
