Vol. IX] VAN DUZEE—NEW HEMIPTEROUS INSECTS 333 



as in itiscomaculatus ; elytra largely whitish, their extreme base and the 

 meso and exocorium beyond their basal third heavily marked with fuscous, 

 the membranal nervures and their margins conspicuously white ; the white 

 apical portion of the second antennal segment nearly equal to the width of 

 the cephalic protuberance. 



Described from one female taken by me at Berkeley, Cal., 

 February 2, 1915. While very near fuscomaculatus this form 

 seems to be sufficiently distinct by the characters of the an- 

 tennae and second genital segment. A. fiiscomaailatiis is not 

 uncommon under bark of rotting live oaks about the bay region 

 and I have specimens taken by Rev. G. W. Taylor on Van- 

 couver Island that do not seem to differ specifically.

3. Aradus blaisdelli, new species 



Closely allied to inornatiis Uhler but with the body much 

 narrowed posteriorly as in dehilis and inornatiis, the rostrum 

 shorter, antennae stouter, sides of pronotum more narrowed 

 anteriorly and the elytra distinctly varied with cinereous, the 

 membrane especially being conspicuously veined with pale. 

 Length 9-11 mm. 



Head about as in inonwtus; antennas similar, scarcely shorter than the 

 head and pronotum together, blackish fuscous, the second segment shorter 

 and a little thicker at base, as long as the head from tip to hind margin 

 of eyes; III and IV subequal, each nearly twice the length of I and a little 

 thinner than apex of II ; apex of IV conical and clothed with the usual 

 grey pubescence. Pronotum twice as wide as long, widest just behind the 

 middle, the broadly expanded sides obliquely narrowed anteriorly, not 

 broadly rounded as in inornatus; margin irregularly denticulate, about 

 three teeth anteriorly much larger; carinas thicker than in inonwtus, the 

 median more distinct across the anterior lobe; tubercles of callosities 

 more prominent, conical. Scutellum more depressed posteriorly with its 

 margins strongly reflexed. Elytra reaching on to the sixth segment in 

 the female, to the genital lobes in the male; humeral expansion broad as 

 in inornatus. Rostrum passing the middle of the mesosternum, but little 

 exceeding its base in inornatus. Genital lobes of male transverse, moder- 

 ately oblique, of equal length across their whole width ; fifth and sixth 

 ventral segments in the female truncate at apex, sixth one fifth shorter 

 than fifth ; apex of first genital segment truncate, straight across its 

 whole margin, in inornatus, a little oblique and feebly notched at center; 

 second segment half the length of first ; genital lobes dorsally triangularly 

 ovate with their hind margin feebly arcuated, their inner margins separated, 

 the ultimate dorsal segment nearly one-half as long as wide, its basal 

 margin regularly rounded, its apical subangularly rounded ; in inornatus 

 this segment is much broader proportionately with the hind edge but little 

 produced, distinctly transversely wrinkled in common with the inner ends 

 of the genital lobes.
