season from April 26th until nearly the first of June. It occurs almost 

 exclusively on a certain fine tufted grass, probably a Poa, growing 

 on the hillsides about La Jolla and up Mission Valley and adjacent 

 canyons as far as the Old Mission and perhaps farther. The bright 

 red on the base of the wings gives this species a lively appearance 

 when spread. Like hesperia Uhler it has the basal one half of the 

 elytra infuscated. It has a shrill but feeble note which is long con- 

 tinued and easy to locate, but can rarely be heard for more than one 

 hundred feet." 



Okanagodes new genus. 



In this genus the uncus is exposed as in Okanagana and the valve 

 and wing venation are the same, but the pronotum is much narrower 

 behind the eyes and the latter are exceedingly prominent. The front 

 protrudes considerably and the supra-antennal plates are also promi- 

 nent. The body is slim with the sides more parallel than in any 

 known species of Okanagana. The type of the genus is the new 

 species described below and figured on the accompanying plate.

sides are more parallel and the wings are proportionately longer. Eyes vary 

 prominent ; fore part of pronotum considerably narrowed. The front is also 

 very prominent with the median sulcus at first indistinct but lower down well 

 developed ; 'the supra-antennal plates are much enlarged. The result of these 

 characters is to give the front of the head, when seen from above, a more 

 uneven outline than in any Okanagana studied. The hook at the end of the
