trum attaining the apex of the intermediate coxe, the basal joint 
clavate, reaching over to the base of the anterior coxe. Basal 
joint of the hind tarsi a little longer than the second; arolia free, 
divergent. 
Type Pycnocoris ursinus nN. Sp. 
146. Pycnocoris ursinus n. sp. 
Color testaceous brown, becoming testaceous on the cuneus, 
abdomen and legs, the corium crossed by two broad fuscous bands, 
one just beyond the scutellum and the other at the apex, the former 
often obsolete. Head tinged with rufous in the region of the tylus, 
Antenne closely clothed with short stiff hairs which become whit- 
ish on the apical two joints; dark rufous brown becoming clear 
rufous on the basal two thirds of the second joint, the basal one 
half of the third joint whitish. Rostrum pale reddish becoming 
black at apex. Pronotum very uniform in color, a little darker 
toward the base and castaneous anteriorly. Scutellum darker on 
the tumid portion. Elytra with the costal area pale testaceous, the 
whitish hairs becoming golden on the dark areas as they are on the 
dark tumid portion of the scutellum. Cuneus rufous or sometimes 
yellowish on the disk, the tip darker or sanguineous, the basal 
angle infuscated. Membrane infuscated, marked with a large 
whitish spot at the tip of the cuneus which may be extended to an 
incomplete transverse vitta, nervures dark sanguineous. Beneath 
more or less sanguineous becoming yellowish on and near the 
coxee and at times on the venter. Meso- and Meta-pleura blackish. 
Legs rufo-testaceous, especially on the femora which are dotted 
with sanguineous, tips of the tarsi infuscated. Length 6-7 mm. 
Described from eight female examples taken from the chap- 
arral at La Jolla, San Diego and Alpine during March and April. 
When immature the insect is more greyish with the cuneus pale. 
This large heavily built insect is very different from anything 
known to me nor can I find any genus that will receive it. At first 
look it would almost certainly be placed near Neurocolpus but its 
true affinities seem to be with Poeciloscytus. 
147. Irbisia pacifica Uhler. Not uncommon in damp situations 
on tall grass. May. 
148. Irbisia brachycerus Uhler. This is perhaps the most abun- 
dant Capsid in cultivated districts in southern California. I 
found it common in Colorado and also have specimens from 
Utah and New Mexico. The legs are ordinarily rufo-ful- 
vous but in some I cannot otherwise distinguish they are 
black. The legs are wanting in Dr. Uhler’s type so we can- 
not tell which form is the typical one but it seems to me we 
might be justified in assuming that it was the more com- 
mon red-legged form that he had before him. If we do 
this we can place Heidemann’s Capsus solani, which does 
not seem to differ specifically, as the black legged form and 
as variety solani it would be equivalent to var. tyrannus 
Fabr. of Capsus ater Linn.
