Vol. VII] GIFFARD— CALIFORNIA HEMIPTERA 257 



61. Corythucha maculata, new species 



Related to fuscigera Stal, but smaller with different areolae and macu- 

 lation. Length 3^, width 1^ mm. 



Pronotal hood about as in spinosa Champ., but somewhat more 

 produced and vertical before where it surpasses the apex of the first 

 antenna! joint; viewed from the side about one-half higher than the 

 median carina and regularly arcuated above; viewed from above nearly 

 globose behind, but not at all transverse; this portion not suddenly con- 

 tracted before and with the areoles rather large and distinct, those of the 

 anterior portion smaller; median carina more depressed anteriorly than 

 in spinosa as figured by Champion, highest about the anterior one-third. 

 Expanded sides of the pronotum elliptical before, almost suggesting an 

 angle there, scarcely surpassing the first antennal joint; areoles small 

 and regular, averaging about one-half the size of those on the posterior 

 aspect of the hood, the marginal row scarcely larger than those of the 

 disk ; marginal spines short, but little more than half as long as the width 

 of the marginal areoles. Scutellum shorter and broader than in spinosa, 

 the elevated margins continued nearly across the pronotal disk. Closed 

 elytra considerably narrowed posteriorly, each elytron widened nearly to 

 its apex ; areoles smaller at base with a few larger ones before the apical 

 dark band; humeral angles well rounded; gibbosities rounded, scarcely 

 higher than the median carina of the pronotum; marginal spines short 

 like those of the pronotum. 



Body deep black; legs and antennae fulvo-testaceous, black at tip; 

 membranous portion whitish-hyaline with white nervures ; disk of the 

 pronotum deep polished castaneous margined with black; nervures of the 

 hood and expanded pronotal margins largely fuscous; scutellar carinas 

 white, the median with an oblique black vitta ; pronotal margins with two 

 fuscous spots, a smaller one before the middle and a larger one at the 

 middle of the hind lobe ; margin of the elytra with a similar spot placed 

 about its own width behind the anterior edge, not attaining the humeri, 

 and a transverse band of about the same width just beyond the tip of 

 the abdomen; posterior aspect of the gibbosities fuscous, the discoidal 

 region more obscure. 



Described from eight examples taken at San Diego, Calif., 

 May 30, 1913. Mr. Fordyce Grinnell has sent me the same 

 species from Pasadena, taken in June, and from Prof. H. F. 

 Wickham I have received a long series, taken at Nephi, 

 Utah, June 30. I also took it at Boulder, Colo., July 21, 

 1903, and at Manitou, Colo., a few days later, and more re- 

 cently Mr. Giffard has taken the same species in the Yosemite 

 Valley, June 16, 1916; in Placer Co., at about 5000 feet 

 altitude, August 20, 1916; on the shores of Clear Lake in 

 Lake Co., August 2, 1916; in Muir Woods, August 16, 1917, 

 and in Redwood Canyon, August 6, 1916. 



This is the form I have listed as fiiscigera from San Diego, 

 but Champion's figure of that species shows it to be a larger 

 insect, in which the pronotal hood is broader posteriorly and 

 suddenly contracted near the middle; the anterior fuscous
