only ; in histrionica obtusely rounded, with their inner margins nearly 

 parallel or at most a little divergent dorsally. 



Color about as in histrionica; black varied with testaceous-white, but 

 faintly tinged with yellow in places. Vertex, pro- and mesonotum with 

 a broad white median vitta bordered either side by a heavy black line ; 

 lateral areas dusky with pale pustules and carinae; discal area of the front 

 entirely white, including the carinae; lateral areas of the front black with 

 a concentric row of about eight white pustules and a shorter row of four 

 next the eye; clypeus black. Elytra reaching to near the apex of the 

 third dorsal segment in the male, to apex of second in the female ; whitish 

 subhyaline, slightly infuscated on the broad clavus, the nervures inconspicu- 

 ous ; broad costal area black, bordered within by a clearer whitish ray. 

 Abdomen hiack ; tergum with three approximate broad white longitudinal 

 vittae, the median bisected by a slender longitudinal carinate black line; 

 sides exteriorly with two longitudinal rows of pale pustules placed on 

 broken pale spots. Pleural pieces above and coxal region more or less 

 whitish ; apices of the femora, lines on the tibiae and basal three segments 

 of the tarsi pale. 



Described from one female and two males, all brachypter- 

 ous, taken by Mr. Giffard near Stockton in the San Joaquin 

 Valley, May 25, 1917. It affords me pleasure to dedicate to 

 Mr. Giffard this interesting addition to the fulgorid fauna 

 of our state in recognition of the services he has rendered 

 entomology by careful and systematic collecting of the Hem- 

 iptera, both here and in the Hawaiian Islands.

 on Baccharis; Mt. Tamalpais, August 16, 1916; near Clover- 

 dale, Sonoma Co., August 3, 1916; Witter Springs ana 

 Blue Lakes, Lake Co., August 2, 1916. 



338. Naethus maculatus fasciatus, new variety 



Differs from the species by having the elytra marked by a continuous 

 broad brown band from the inner angle of the clavus to the apex of the 

 costal areole, and a still broader one at apex, omitting, however, the apical 

 row of small areoles and usually a number of the subapical. These bands 

 may vary in width so as to connect with the form described by Melichar 

 where they are broken into spots and at times become nearly or quite 

 obsolete. 



Described from a long series taken near Lakeport, Lake 

 Co., by Mr. Giffard and myself, August 2, 1916.
