rounded or subangular; genital lobes short and broad, scarcely angled 

 behind, their inner margins rounded, distant, much as in compressus. 



Color uniformly blackish fuscous ; legs, inner edge of the genital lobes 

 and sometimes the hind edge of the ventral segments tinged with cas- 

 taneous. 



Described from two male and three female specimens taken 

 by me under loose bark of a stump of lodge-pole pine at 

 Huntington Lake. Fresno Co., Cal., July 17, 1919, at an 

 elevation of 7,000 feet. In this species the pronotum has 

 about the form found in heidemanni but without the marginal 

 crenulations ; the male elytra are narrowed much as in the 

 female heidemanni but in a less degree, while the females are 

 brachypterous. It has much in common with compressus near 

 which it should, perhaps, be placed.

8. Aradus evermanni, new species 



Near gracilicornis Stal ; forni parrow, subparallel; antennse 

 shorter; pronotum shorter, its /ides paler and more deeply 

 denticulate, humeral angles more rounded ; scutellum broader ; 

 elytral areoles reticulate. Length 4^ mm. 



Female : Head as in gracilicornis. Antennae slender, as long as the 

 head and pronotum united ; first segment but little longer than thick, cylin- 

 drical ; II distinctly longer than III and IV together, its immediate apex 

 thickened, but little narrower than I ; III and IV subequal, about as long 

 as the dorsal thickness of the cephalic process ; III cylindrical, IV fusi- 

 form. Rostrum just attaining the anterior coxae. Pronotum distinctly 

 shorter than the head, its median length one half its basal width ; sides 

 broadly flattened, strongly crenulate, slightly sinuated anteriorly without a 

 distinct apical tooth; humeri broadly rounded, (in gracilicornis the sides 

 are nearly parallel behind the widest point) ; six discal carinse about as in 

 its ally except that the median pair diverge more posteriorly. Scutellum a 

 little shorter and proportionately broader than in gracilicornis, nearly 

 one fourth longer than the pronotum. Elytra as in the allied species, all 

 the areoles white, crossed by irregular fuscous veins ; membrane distinctly 

 maculated. Apex of fifth ventral segment truncate across the middle, its 

 median line distinctly longer than the sides, its disk without a transverse 

 impressed line; sixth segment on its median line as long as the fifth, very 

 slightly excavated at apex, its apical angles equalling the genital segment ; 

 first genital segment truncate at apex, about twice as long as the apical, 

 the valves of the latter triangular; genital lobes narrow and strongly 

 curved at apex, almost meeting bej-ond the genital segment, their apical 

 margin truncate and a little oblique. 



Color black ; first three segments of antennae, expanded margins of 

 pronotum, elytral veins, except at base and apex, and the connexivum 

 obscure brown; incisures of the connexivum broadly pale.
