| HEMIPTERA. VAN DUZEE. 9 
tenne slender; basal joint exceeding the tip of the tylus by one 
| half its length; much thicker at apex; second joint longest, one and 
one half times the length of the first; third three fourths the length 
of the second; fourth nearly as long as the second, fusiform; all 
the joints but the first minutely hairy. Rostrum reaching to be- 
tween the intermediate coxe; first joint surpassing the hind angle 
| of the eye, second attaining the anterior coxe. Pronotum distinct- 
| ly shorter than the head and shorter than its basal width; anterior 
lobe strongly convex, smooth and polished above; posterior as long 
as the anterior, polished, with coarse distant punctures, the middle 
line slightly raised and smooth; humeri prominent, smooth and 
subtuberculate, hind edge straight. Scutellum long and acute at 
apex, punctate, with a smooth median line on its apical two thirds. 
Elytra polished, punctate, the claval punctures fewer and less con- 
fused than in plebejus. Pleural pieces strongly punctured. Anter- 
ior femora much incrassated with eight or ten teeth, the middle 
ones much longer. Venter impunctate, scarcely polished; no lun- 
ate vitta. 
Color piceous brown becoming almost black on the pronotum, 
scutellum and pelural pieces; head rufopiceous; elytra verging into 
fulvopiceous in places, the costal margin narrowly paler, with an 
indication of the paler square anteapical spot found in Ligyrocoris 
contractus and other allied forms. Antenne, at least the second 
and third joints, and the legs flavo-piceous, all the femora with a 
subapical blackish cloud which seems to be wanting on the anterior 
femora of the male. 
Described from one male and two female examples taken at 
Alpine, March 11th, 1914. These were swept from grass and 
- weeds on the high adobe lands south of the village. I have one 
larger female that was taken by Prof. J. C. Bradley at Leona 
Heights, Alameda County, California, in August.
