14. Clidophleps distant! var. pallida Van U. 



Van Duzee, Trans. San Diego Soc. Xat. Hist., II, p. 47, 1914 {Okanagana). 



Size of tntiicata or a little smaller but with the markings more 

 extended and the last ventral segment more rounded at apex. I found 

 this form along the sea shore at National City at San Diego. It 

 did not seem to have the habit of sounding in unison as do the other 

 forms of this species. 



Genus 6. OKANAGANA Dist. 

 Distant, Ann. Mag. Nat. Hist., Ser. 7, XVI, p. 23, 1905. 



This genus is distinctively Californian. So far as I know but 

 two species are found east of the Rocky Mountains and most of 

 them seem to be confined to the Pacific Coast States. It may be dis- 

 tinguished from Tibicina by its narrower head which is not wider 

 than the mesonotum. The genus is very poor in structural char- 

 acters so the species are best separated by size and color markings. 

 They are, however, well distinguished by their general facies, habitat 

 and song and in field work there is little danger of confusing them. 



15. Okanagana cruentifera Uhler. 



Uhler, Trans. Md. Acad. Sci., I, p. 161, 1892 (Tibicen). 



This species was described from Colorado and Xevada. I am 

 doubtfully identifying it with a large black species with bright orange 

 costa which has been taken near San Bernardino. I have seen but 

 three specimens, all females. In this species the head is unusually 

 narrow and pointed (7 by 4 mm.) ; pronotum 5 by il mm. Length 

 33 mm., expanse S;^ mm. Color black, scarcely polished, well clothed 

 with long pale hairs ; pronotum immaculate or with the lateral areas 

 obscurely pale; costa, base of wings, legs in part, margins of the 

 apical segments of the tergum, ventral segments and genital pieces 

 bright orange. 



16. Okanagana ornata new species. 



Allied to rimosa but a stouter and broader winged form. Black with the 

 costa and commissure on basal one half and the wing veins bright orange. 

 Length 23 mm.; to tip of elytra 36 mm.; elytra 10 by 30 mm. head 3^/2 by 7 

 mm., pronotum 4 by gV2 mm., width of mesonotum 8 mm. In tiii.^ form the 

 first apical areole is unusually long (8 mm.) and is equal to four fifths the
