Diagnosis. — The species may be recognized by either the pale 

 costal region of the fo^e\^dng, the compressed and protruding central 

 beak of the frons, the absence of a discal spot, or the fact that K.2 is 

 almost always the first vein to leave the stalked K.2-f-4.

 outer sides and dorsally, light brown to white ventrally; antennae as 

 in calif orniella; patagia, tegulae, vertex, occiput, and legs as in cali-
