Arizona. 



A single female specimen representing a species which is allied 

 to bifasciatus, but differing in coloration and several structural 

 charactei's. The configuration of the anterior pale fascia in 

 bifasciatus is perfectly constant throughout my series. 



I¥. moil tail lis. — Stout, rather sliininf^, testaceous, the ahdomen darker; 

 eh'tra dark piceous-hrown, ^vith a broad oven and parallel-sided transverse fas- 

 cia of paler tint at basal third, and another, narrower, at apical third, the 

 latter bent forward toward the suture; base and apex also paler; vestiture 

 short, not very dense, somewhat coarse on the prothorax, intermingled with 

 sparse erect sette on the elytra. Head much smaller tban the prothorax, pol- 

 ished; eyes small, barely as lonu; as the tempora; antennaj two-fifths as long 

 as the body, moderately incrassate, the tenth joint one-half longer than wide. 

 Prothorax slightly wider than long, the sides oblique to the bjise behind the 

 middle; surface finely, densely and rather rugosely punctate; horn well de- 

 veloped, about one-third longer than wide, distinctly constricted at base, the 

 sinuation broad, the border entire, the crest well developed, with its border 

 strongly reflexed and entire. Elytra distinctly dilated and, at apical third, 

 almost twice as wide as the prothorax, scarcely more than three-fourths longer 

 than wide, broadly, feebh^ transversely impressed at basal third, strongly im- 

 pressed on the suture behind the scutellum, the humeral impression obsolete; 

 punctures somewhat fine but distinct, rather dense. Under surface densely 

 pubescent, nnnutely, densely punctate, the legs slender. Length 2.9 mm.; 

 width 1.0 mm. 



Colorado. 



This species, while allied in general appearance to some others 

 of this group, ma^^ be distinguished by its stout form, and, from 

 balteatus, by its smaller eyes, coarser punctuation and erect set;u 

 of the el^^tra, these being completely wanting in that species. 

 From bifasciatus it differs in its much longer and more distinct 

 erect setfe, non-interrupted elytral fasci;v, dehiscent tips of the 

 el3'tra, less incrassate antennfe and many other features. It is 

 represented before me by the female only. 



IV. iilici'occi'llfii. — luither narrow, polished, dark rufo-piceous, the abdo- 

 men black; elytra black, with a straight transverse and entire fascia just be- 

 hind basiil fourth, and, on each, a transverse spot at apical fourth which is 

 flexed obliciuely forward, liecoming feeble, to the suture; base slightly, the 

 apex not appreciably, pale. Head but slightly smaller than the prothorax, 

 polished, the eyes well developed; antennie long, slender, scarcely at all in- 

 crassate, more than one-half as long as the body, dark rufo-testaceous through- 

 out, the tenth joint about one-half longer than wide on the comjiressed side 

 and nearlj' twice as long as wide <m the other. Prothorax small, subglobular, 

 a little wider than long, coarsely punctato-seabrous, except broadly along the
