indecl at apex. Plates of the nude about as long as the valve, triangu- 



apex acute, the sides a little eoneavely areuated and fringed with pale 

 slid bristles.

California. Described from four male examples received 

 Mr. D. W. Coquillett. This. is a smaller and darker species than 

 acutus with the plates and valve much shorter and the face 

 entirely pale yellow. P. frontalis has a shorter vertex, the outer 

 margins of the cheeks arc brown and the form of the genitalia 

 is quite different.
