hyaline and when viewed from behind having a purplish iridescence. 

 Marginal areole long, narrow and largely infuscated as in Okanagana. 

 First, second and third ulnar areoles elongated and similar in form. 

 Apical areoles eight in number as in Okanagana with which genus it 

 agrees in most of its other characters. 

 Type Okanagana distant! Van D.

In the Transactions of the San Diego Society of Natural History, 

 Vol. II, p. 47, 1914, I have given my reasons for identifying this 

 species with our smaller and more slender form. I have taken it 

 only from San Diego Co. and have not seen it in other collections. It 

 is not unlikely that it is a Mexican form with its northern limit of 

 distribution near San Diego.

This is a larger and ibroader form than blaisdelli with a broader 

 costal areole and with the costa more strongly bent at the node. It 

 has the last ventral segment of the male narrower and truncated or 

 feebly emarginate at apex; the pale spots at the anterior points of the 

 mesonotal X are usually pyriform and enclose a black point; the hind 

 margin of the pronotum, a conspicuous median vitta almost inter- 

 rupted near the hind margin and the very narrow anterior margin 

 are pale, and the lateral areas of the pronotum are obscurely paler. 

 Length of body 25 mm., to tip of elytra 34 mm. 



This interesting species is abundant on the chaparral on the higher 

 pueblo lands about La Jolla, San Diego Co. during May and June, 

 It has the habit of shrilling in unison at intervals of from ten to 

 thirty minutes, apparently depending on the strength of the sunshine. 

 They are strong flyers and have a loud rattling note. It is known 

 only from San Diego Co., Calif.

Differs from the typical form in being smaller (22 mm.) with the 

 elytral nervures paler and the last ventral segment of the male 

 shorter and more truncate at apex. From San Diego Co., Calif.
