This insect is remarkable for its very robust form, from which pecu- 

 liarity I have given it the above generic name. It appears closely allied to 

 the Lamia nigricornis of Fabricius, found at Bombay and at Poonah ; but 

 instead of belonging to the Lamiadce, it appears to be a subgenus closely 

 approaching Saperda. There are also several other allied exotic genera 

 belonging to the Saperdidce which are at present undescribed.
