Okanagana vwriposa, it differs in having a hooked uncus instead of 

 a nearly straight one; it is also more hairy. From Okanagana van- 

 diiccci, which has a hooked uncus, it differs in being much larger, 

 in having the eyes more prominent, the anterior angles of the prono- 

 tum more rounded, the front wings with the outer margin straighter, 

 and the last ventral segment more rounded at the extremity, instead 

 of somewhat sinuate. It, however, should be placed next to 

 z^anduccci. 

 Okanagodes gracilis Davis. 



In the original description. Journal N. Y. Ento. Society, June- 

 Sept., 1919, this species was reported from Utah, and two localities in 

 Arizona. On August 6, 19 19, at Bagdad, San Bernardino Co., Cali- 

 fornia, Mr. Morgan Hebard collected two males on low plants in 

 an arid environment. He was attracted by the song, which he at 

 first thought was produced by an Orthopterous insect. The Cicadas 

 ceased singing when he was still some distance from them, which 

 made their final detection rather difficult. 



Platypedia putnami var. keddiensis Davis. 



Recorded from Keddie, Plumers Co., and Lassen Co., California, 

 also Corvallis, Oregon. Recently Mr. E. R. Leach kindly sent me 

 two males and a feniale collected May 2^, 1920, in Nevada Co., 

 California. 



Platypedia laticapitata new species. Plate II, fig. 5. 



Type male. Upland, San Bernardino Co., California, June 24, 1920: allo- 

 type female from the same locality, July i, 1920; both collected by Miss Esther 

 P. Hewlett, and in Davis collection. 



Resembles Platypedia aperta Van D. in its narrow fore wings ; the uncus, 

 however, is much narrower, and more as in P. vanditseei, from which it differs 

 in not having the broad wings nor the very hairy head of that species. The 

 head is also very hairy in minor and barbata. 



Front of head not prominent and about as in the other small species of 

 the genus ; median sulcus moderately well defined and broadening on the lower 

 part of the face. The head is wide across the eyes, and the pronotum broadens 

 from the collar toward the anterior margin, so that it is proportionately wider 

 just behind the eyes than in any other Platypedia so far examined. Hairs on 

 the greater part of the dorsal surface short and appressed, giving the insect 

 a dull gray-black appearance ; in aperta, vanduzeei, minor and barbata the 

 hairs on the upper surface of the thorax are rather long, upright and dark 

 colored. Hairs on the underside of the body longer and lighter colored, as is
