Van Dyke found one in a similar situation, and I took a male 

 near Glen Alpine Springs, June 30. 



Aradus huhhardi Heid. A fine series of this species was taken 

 from fungus growing on a fallen pine tree along the trail to 

 Angora Lakes at an altitude of about 7000 feet, July 11. In all 

 the specimens taken the tip of the second antennal joint is scarcely 

 paler. 



Aradus persimilis, new species 



Very close to huhhardi, differing principally in having the scutellum much 

 broader at apex, the expanded portion of the eosta longer and the antennae 

 a little thinner, with their second segment perhaps a little longer and 

 the third without a pale apex. Length, male 6.5 mm., female 7.5 mm. 



Head as in huhhardi; anterior process thick, cylindrical, compressed 

 toward the apex, reaching nearly to basal third of second antennal joint. 

 Spine at base of antennae almost attaining the tip of first joint and armed 

 exteriorly with a very short tooth. Occiput with a tubercle before the 

 eye and another near its hind angle. Antennae about as in huhhardi, 

 perhajjs a shade thinner; first segment about one-half longer than wide, 

 second about as long as the head, a little thickened at apex; third hardly 

 one-half the length of second; fourth still shorter, narrowed to its base 

 with a short conical tip. Pronotum about as in huhhardi, slightly longer 

 and more broadly expanded about the humeri; sides irregularly dentate; 

 four discal carinae nearly parallel, exterior percurrent, not becoming 

 obsolete before as in the allied species. Abdomen as in huhhardi; genital 

 segment of the female a little shorter and less expanded; genital lobes of 

 the male shorter and more transverse. Rostrum nearly attaining hind 

 margin of mesosternum. 



Color fuscous-brown, becoming more ferruginous on the cephalic pro- 

 cess, basal joints of antennae, pronotal carinae, principal elytral nervures, 

 extreme tip of scutellum, and in places on abdomen. Antennae becoming 

 black on apical two segments, conical tip of fourth sericeous pubescent. 

 Expanded basal portion of costa and broad humeral areas and marginal 

 serrations whitish-testaceous; elytral reticulations sometimes of the same 

 pale color. Legs and beneath usually paler. Abdomen becoming more 

 castaneous toward its margin, where it is often minutely pointed with 

 green, the hind edge of the connexival segments pale; membranal veins 

 distinctly pale. 



Described from three male and two female specimens taken 

 near Glen Alpine Creek, June 25 to July 3. While very near 

 hubbardi this form seems to have good specific characters and is 

 at least a valid subspecies. I possess one female, taken by Dr. 

 J. C. Bradley in the Santa Cruz Mountains, California, in May, 

 1907, that differs from the types only in having the humeral 

 expansion of the pronotum concolorous.
