Hi/popus. LengtJi varying from 210 to 290 ^i ; breadth varying con- 

 siderably in the same individual , as it is able to bend downward and 

 inward its sides. Generally it has the form delineated in Hg. 38 and 39, 

 but when even slightly pressed by the covering-glass it becomes very 

 broad (fig. 40). Colour brown. Shape oval , with the top directed 

 backward, but with a triangular slip on the aiterior base. 



Dorsal side (Fig. 38), Céphalothorax small, about one fifth of 

 the animal's total length. Line of demarcation between céphalo- 

 thorax and abdomen convex forward. The skin is quite polished , 

 no trace of punctulations , etc. On the céphalothorax I could discern 

 3 pair and on the abdomen 9 pair of minute hairs. 1 am convinced 

 that with the position of these hairs, how minute they may be, 

 it is possible to determine the species. There is a shoulder-hair and 

 backward a marginal hair behind coxa 3 and behind coxa 4. There 

 are two longitudinal rows of siîi hairs each. On the céphalothorax
