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 Lamiade, it appears to be a subgenus closely 
approaching Saperda. There are also several other allied exotic genera 
belonging to the Saperdide which are at present undescribed.
