Characters. — Head (including eyes) little more than two thirds the breadth of base of meso- 

 notum, anteriorly depressed, its length only a little more than half the breadth between eyes; pronotum 

 considerably shorter than 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 abdominal 

 margins; rostrum reaching or passing the posterior coxa? ; metasternum very large; opercula about half 

 the length of abdomen above, broad, their apical margins convexly rounded, their lateral margins 

 almost straight; tegrriina and wings (excepting base) hyaline, the first broad, their greatest width a little 

 less than half their length, apical areas eight in number, the two lowermost small, subquadrangular.
