 lum large, rounded in front, angulated behind with 

 an inflated point : elytra meeting in a straight suture 

 down the back, semi-transparent, reticulated and 

 covering the abdomen : legs of moderate length and

Inhabits oak trees in the months of August and 

 September. 



Of this genus only one species has yet been ob- 

 served in this country. The pupa is active, it has a 

 scaly appearance, and resembles the perfect insect, 

 but is destitute of wings ; in this state we have taken 

 it from the oak in the month of August, when in 

 the entomologist's net it lies close, and looks like 

 a piece of the rind of a tree. They are not common.
