576 Longicornia Malayana. 



Pyrestinj;. 



This subfamily is more remarkable for the rich blood- 

 red, or yellowish-red, colour of its members, than for any 

 very trenchant characters by which it may be distin- 

 guished. With one exception — Dalila — all the genera 

 are Asiatic.

 verse striatus. Elytra parallela vel postice paulo 

 latiora, epipleurae basi sinuatse. Pedes breves, fere 

 sequales, vel postici paulo longiores ; femora in medio 

 gradatim incrassata; tarsi postici breviusculi. Pro- 

 sternum angustum, elevatum. Mesosternum antice

This description will apply to both sexes, so far as I 

 am able to judge from an example of the male of P. car- 

 dinalis, only that the antenna extend nearly to the apex 

 of the elytra in the male, while in the female, they do 

 not go beyond half the length, and are more broadly 

 dilated. There are eight species described, only one of 

 which was found by Mr. Wallace. Wherever they occur 

 they appear to be amongst the rarest of Longicorns.
