 Mountains in May, 1891. 



BEllYTINyE. 



Pronotacantha n. gen. 



Form of Parajalysus Distant, but with long, erect, remote spines on all sides of the 

 pronotum, those of the front border directed obliquely forwards, those of the sides 

 pointing outwards, the posterior pair pointing backwards, and the single one on 

 each humerus curved at tip, posterior portion of the pronotum convex, very much 

 elevated behind, emarginated for the base of the corium. Scutellum small, flat, 

 armed with a long slender spine. Epipleura with a short tooth beneath the base of 

 the wing-cover. Antenna? and legs with the usual knobs at end of joints. Wing- 

 covers flat, very much wider and longer than the abdomen, nearly spindle-shaped 

 in outline, almost membranous and translucent throughout, the costal areole wide, 

 crossed by a coarse diagonal vein, followed by a longer areole which is also bounded 

 at tip by a diagonal vein which sends off a thinner vein to curve outward and bound 

 a narrow, cuneus-like areole running to the tip of the wing-cover, behind this, ex- 

 tending inwardly, are four long areoles which constitute the end of the wing-cover. 

 Abdomen a little swollen at base, narrow behind. Middle coxte placed far back from 

 the anterior pair, but not remote from the posterior coxae. 



P. armulata n. sp. 



Pale fulvous, with the head, front, and back of the pronotum polished black. 

 Head short, subglobose, with the tylus forming a prominent vertical ridge, bounded 

 by swollen cheeks; eyes prominent, brown; rostrum reaching to behind the middle 

 coxa?, dark piceous, paler on the middle and beneath. Antenna? long and slender, 

 aunulated with black, the basal joint longer than the head and pronotum united, a 

 little thickened at tip, second joint about one-half as long as the basal, the third a 

 little longer, the fourth joint black, pale at tip, Aery short and thick, fusiform but 

 acute at both ends. Pronotum stout, broad and tumid behind, black, polished, with 

 a broad yellow band which narrows below and extends upon the sternum, spines 

 chiefly yellow, those of the base longer. Scutellum narrow, testaceous, armed with 

 a long, erect, yellow spine. Legs slender, testaceous, banded with black, the femora 

 clavate and wax-yellow at tip. Wing-covers testaceo-hyaliue, almost membranous 

 throughout, the veins delicate and a little deeper colored than the integument, those 

 of the corium thick, brown, especially the costal one, the corium unevenly punctate, 

 very short, triangular at tip, with the costal rib carried far beyond its tip; the mem- 

 brane is much longer than the corium and extending well along its inner border, 

 and has a series of four long and wide areoles. The cubital area is long, narrow, ob- 

 lique at tip, and from it is continued a much narrower apical areolar extension, and 

 these areas are all punctate and minutely bristly along the veins. Abdomen polished, 

 somewhat piceous at base and tip, tinged with rufo-ferrugincous on the sides supe- 

 riorly, acutely narrowing towards the tip in the male. 



Length to end of abdomen, 4 mm ; width of pronotum, f mm . One specimen, a 

 male, was taken on the Argus Mountains in April. This specimen has the greater 

 portion of the veins of hemelytra pale brown. Several other specimens from differ- 

 ent parts of Arizona have been submitted to me for examination.
