 globular, moderately directed upward ; pronotum a little 

 narrowed behind eyes, about as long as niesonotum in front of 

 the cruciform elevation ; abdomen longer than space between

 notum considerably shorter tlian mesonotum, its lateral 

 margins obliquely sinuate ; mesonotum somewhat convexly 

 gibbous ; abdomen short, broad, convex above, its length 

 equal to the space between apex of head and base of cruciform 

 elevation, the lateral margins a little angulate at posterior 

 segmental angles ; tympana completely covered, lateral 

 margins of the tympanal coverings subparallel to the abdo- 

 minal margins ; rostrum reaching or passing the posterior 

 coxae ; metasternum very large ; opercula about half the 

 length of abdomen above, broad, their apical margins con- 

 vexly rounded, their lateral margins almost straight ; tegmina

 sinuate ; abdomen narrowed posteriorly in both sexes ; the
