5. — Erassus infletus, sp. n., PI. I, Eig. 4, ? • 
Adult female: length 3^ lines. 
The cephalothorax 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 
f lfii'k hairs. 
The eyes are in two transverse, slightly curved, and very nearly concentric, curved rows, 
dose 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, hut 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 latcials of the two 
rows is nearly, if not quite, et^ual to the diameter ot the largest of them, w Inch 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 
if by an interval equal to its own diameter ; the fore-central eyes are the lai gest of the 
eight, and the spot on which they are seated appears to he a little prominent ; the height of 
tbe 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 
ar c of a brownish-yellow colour, deepening to reddish-brown on the metataisi 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 
ra< lial and digital joints deepening to red-brown. 
aloes are tolerablv long and strong, directed a little forwards; their colour is like 
^at of the cephalothorax,’ ' and they are furnished in front with hairs, bristles, and greyish 
Pubescence. 
The maxillce 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 maxillm in colour.
