angulated externally. Mctastenmiii sliortci- lliaii the nicso- 

 stenuun. Interfemoral ])r()ces.s rather narrow, triaiiuiilar. 

 Abilonien with the ventral sei^nients nearly e(|ual in l('ii,L;th. 



Tiiis <;-enus and the l()l](jwing are so tar cunneeted that in 

 both the Hanks of the prothonix arc not se])arated from the 

 pronotum, and the mentum is sessile to the throat. In other 

 respects their principal characters are very dissimilar. F()r 

 further remarks I must refer to the next genus.

 suture ; antennary ridge small, auriform. Eyes conically pro- 

 jecting, round, entire. Antennae exposed at their insertion,
