230 AENIDEA SUMATRENSIS. 



contained in my collection; in that of the collection of 

 the Ley den Museum the antennae are wanting , but the 

 insect agrees in every particular with my specimen ; the 

 female has a more transverse thorax and the depressions 

 of the latter are less deep ; the elytra are more distinctly 

 costate; the clypeus is divided at the middle by a longi- 

 tudinal ridge , the sides being also excavated , but not the 

 front as in the male; the antennae are simple and have 

 the third , fourth and fifth as well as the two apical joints 

 fuscous ; the female and male insect contained in my col- 

 lection (also from Sumatra) are black below; those collec- 

 ted by Dr. Hagen are fulvous.
