2 PRIONOTA. 



In the robust stature , the shape of the head , the long 

 flexible terminal joint of the palpi and the neuratiou of 

 the wings this new genus agrees with Ctejiophora , but it 

 may be distinguished by the antennae , which in both sexes 

 are strongly enlarged on one side and somewhat sawlike. 



Face conically prolonged downwards and extended to a 

 sharp point; eyes round, slightly prominent. Antennae 

 stout , composed of thirteen joints , with exserted hairs ; the 

 two basal joints as in Ctenophora ; the third and following 

 ones slender at the base , and enlarged into a broad knob 

 towards the underside , in consequence of which the antennae 

 have a sawlike appearance; the apical joint subulate. Palpi 

 four-jointed ; the terminal joint as lojig as the three prece- 

 ding taken together. Thorax convex ; pronotum distinctly 

 separated. Abdomen oblong, composed of eight segments ; 

 genitals of the male but little swollen. Legs stout ; ti- 

 biae , at least the hind ones , with short spurs. Wings as 

 long as the abdomen; the second posterior cell sessile.
