dalis brevicorjiis, Lin. Lymexylon ahhreviatum. Fab. 

 Macrogastcr abhreviatus, Thunb. is found in Guinea, and 

 appears to differ but little from another species received from 

 Brazil. The Museum of Natural History possesses a se- 

 cond, much smaller, and perfectly distinct, enclosed in amber. 

 Another is found in Java. 



Those in which the elytra are of the length of the abdo- 

 men, or but little shorter, form two sub-genera. 



In these the antennae are compressed, serrated, and with 

 transverse articulations. The corslet is almost squared.
