 than thorax, sutural and discal lines distinct, parallel, the latter deep at 

 base and reaching apical fifth. First dorsal of male deeply concave, pro- 

 longed behind in two acute triangular lobes; second dorsal with a large 

 median fovea. Length l.S mm. (Fig. 150, a.)

 The following species are known from or perhaps occur in the State :
