March, igis-] Van Duzee : West Coast Cicadid.e. 31 



lection of the California Academy of Sciences taken by Dr. E. C. 

 Van Dyke in Marin Co. in April and May. Dr. Blaisdell has also 

 taken this species in the Mokelumne Hills, Calaveras Co., Calif. Mr. 

 Davis's specimen is a female from Utah and is larger than any I 

 have seen from the coast. 



10. Platypedia putnami Uhler. 



Uhler, Bui. U. S. Geol. Geog. Surv., Ill, p. 455, 1877 (Cicada). 



Under this name I have placed the larger species in which the 

 ground color is more of a blue-black and the pale markings are of 

 a deep or reddish orange. The elytra measure 8—9 by 23—24 mm. ; 

 the anterior edge of the pronotum is slenderly pale ; the basal half of 

 the first antennal joint is pale as are also the margins of the frontal 

 sulcus, median carina of the clypeus and first joint of the rostrum. 

 Here the sinus of the last ventral segment of the female is broader 

 and this segment in the male is shorter and almost truncated at apex; 

 the uncus is strongly arcuated below and slightly so above, with 

 apex obtuse: the discal nervures of the elytra are piceous nearly to 

 their base; the inner margin of the second ulnar areole is almost 

 rectilinear and there is a distinct pale dot at the middle of the basal 

 margin of the vertex. The eyes also are noticeably more prominent 

 and the front less hairy. Length to tip of the abdomen 21-24 mm. 

 I have before me material from Colorado, Utah, Nevada, Oregon 

 and from Siskiyou and Trinity counties, Calif., the latter taken at 

 Carrville in June by Dr. E. C. Van Dyke. 



Normally all our species of Platypedia have the following pale 

 markings : sides of the face, supra-antennal plates in part, median 

 line and hind edge of the pronotum, hind margin of the metanotum 

 including the posterior one half of the elevated X, the costal nervure 

 as far as the node and the propleura superiorly. 



Genus S- CLIDOPHLEPS new genus. 



Allied to Okaiiagaiia with the same form of head and pronotum, 

 approaching Platypedia in its expanded elytra, and well distinguished 

 from both by the greatly thickened and nodose transverse vein at the 

 apex of the clavus. Costal nervure distinctly bent at the node giving 

 the closed elytra a bullate aspect when viewed from above. Elytra
