Arizona. 



A single female specimen representing a species which is allied 

 to hifasciatus, but differing in coloration and several structural 

 characters. The configuration of the anterior pale fascia in 

 bifasciatus is perfectl}^ constant throughout ray series, 



N. moil tan lis. — Stout, rather shining, testaceous, the abdomen darker; 

 elytra dark piceous-brown, with a broad even 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 setse on the elytra. Read much smaller than the prothorax, pol- 

 ished; eyes small, barely as long as the tempora; antennae 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 base 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 Avide as the prothorax, scarcely more than three-fourths longer 

 than wide, broadly, feebly, 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, minutely, 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, may be distinguished by its stout form, and, from 

 balteatus, by its smaller eyes, coarser punctuation and erect setae 

 of the el3^tra, these being completely wanting in that species. 

 From bifasciatus it differs in its much longer and more distinct 

 ei*ect setge, non-interrupted elytral fascire, dehiscent tips of the 

 elytra, less incrassate antennae and many other features. It is 

 represented before me b}^ the female onl^'. 



IV. illicrocerus. — Rather naiTOw, polished, dark rufo-piceous, the abdo- 

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

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

 flexed obliquely forward, becoming feeble, to the suture; base slightly, the 

 apex not appreciably, pale. Head ])ut slightly smaller than the prothorax, 

 polished, the eyes well developed; antennae 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 compressed side 

 and nearly twice as long as wide on the other. Prothorax small, suhglobular, 

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