is blunt and obsolete, and the spines are short and very fine. 

 In the £ the third ventral segment is simply flattened, but on a 

 huge surface. In the £ the joints of the antennae 3-7 are a little 

 longer than broad, 7 being evidently longer than the preceding 

 line, S-9 are square, 10 is ovate, thicker, and as long as the two 

 preceding ones together, 1 1 is oblong, longer than the three pre- 

 ceding ones, a little broader towards the apex, obtusely acuminate.

This species, of which I have a typical example (<£) from Dr. D. 

 Sharp himself, is very closely allied to Kreusleri : the carina and 

 spines of the underpart of the head are alike very strong, but th e 

 antennae are a little shorter and thicker, the palpi are very 

 different and resemble more those of morosus. However, the 

 fourth joint is more transverse and the third more elongate.
