336 Longicornia Mahiyana. 



according to the light, on a liiteous, or occasionally dark brown 

 or black, derm. On the prothorax there is a kind of sharp lon- 

 gitudinal elevation in the middle terminating'posteriorly just before 

 the base in a slightly abrupt point. The same character occurs 

 in Entelopes and Xyaste. Besides the species described below 

 there are a few specimens from Waigiou, Bouru, Sarawak and 

 Sumatra, which are very close to some of these, but cannot at 

 present be satisfactorily referred to any of them.
