5. DRASSUS INFLETTJS, sp. n., PL I, Fig. 4, ? . 



Adult female: length 3J lines. 



The ceplialothorax is of a rather elongate-oval form, narrowing gradually to the fore-ex- 

 tremity, which is truncate ; the lateral impressions of the caput are very slight ; looked at in 

 profile, the fore-part of the caput slopes very little forwards, and the hinder (or thoracic 

 slope) is short, abrupt, and rather rounded. The normal indentations are ill-defined, and the 

 central thoracic groove is indicated by a short red-brown line ; the colour of the cephalo- 

 thorax is yellow-brown, and it is covered with a grey pubescence, among which are some 

 dark hairs. 



The eyes are in two transverse, slightly curved, and very nearly concentric, curved rows, 

 close to the fore margin of the caput ; they are of moderate size, not greatly different in this 

 respect, and pretty compactly grouped together ; those of the front row are very near to- 

 gether, but the interval between the two central eyes of this row is rather greater than that 

 between each and the lateral eye nearest to it ; the interval between the laterals of the two 

 rows is nearly, if not quite, equal to the diameter of the largest of them, which appears to 

 be that of the front row; those of the hind-central pair are contiguous to each other, oblique, 

 of an oval form and pearly lustre, and each is separated from the hind-lateral eye nearest to 

 it by an interval equal to its own diameter ; the fore-central eyes are the largest of the 

 eight, and the spot on which they are seated appears to be a little prominent ; the height of 

 the clypeus is no more than equal to the diameter of one of the last-mentioned eyes. 



The legs are tolerably strong but rather short ; their relative length is 4, 1, 2, 3 ; they 

 are of a brownish-yellow colour, deepening to reddish-brown on the metatarsi and tarsi, and 

 clothed with greyish pubescence mixed with darker hairs, bristles, and spines ; the last 

 chiefly on those of the third and fourth pairs ; beneath the two claws with which the tarsi 

 terminate is a small claw-tuft. 



The palpi are short, pretty stout, and similar to the legs in colour and clothing; the 

 radial and digital joints deepening to red-brown. 



The fa Ices are tolerably long and strong, directed a little forwards; their colour is like 

 that of the ceplialothorax, and they are furnished in front with hairs, bristles, and greyish 

 pubescence. 



The maxillae are strong, slightly curved, and inclined towards the labium, as well as 

 broadly impressed across the middle ; the basal portion is broad and rather convex, and its 

 colour is darker than that of the cephalothorax. 



The labium is oblong, rounded at the apex, and similar to the maxillae in colour.
