This genus differs fr "m Loctsta and Acrydum, by the long an<l sharp triangular outline 

 when seen from above, or rather the double triangular form of the body of the insect, the 

 base or widest part being between the middle legs, from which it taf»er5 each way ; the 

 head being smaller than in the furmer genera. The insect is small, with small wing-covers ; 

 but the wings are large in prof^jriion to the size of the tiCKlj", and scolltpped on the edge. 

 The females have four l>oring appendages, which are notched on their edges. 



Dr. Hareis divides the genus into two group>s : first group, antennae 13- or 14-jointed; 

 second group, 22-jointed, with additional characters not necessary to be noted here. 



For a very fuU account of these three genera, see Habbis's Treatise on Insects, 2d ed.
