Body much smaller than in su/cafu/us, the elylral sulci much less 

 coarse and not so deep, piceous brown in colour ; beak well de- 

 veloped, densely squamose except apically, evidently arcuate ; 

 prolhorax coarsely, closely punctate, not so long as wide, three-fifths 

 as wide as the elytra, parallel, with rounded sides, constricted and 

 narrowed apicaily, the large pale scales dense, nearly wanting at each 

 side of the middle basally ; elytra twofifihs longer than wide, feebly, 

 arruately narrowing behind the middle, the apex obtuse; humeri 

 rounded, moderately exposed ; pale rounded scales more abundant 

 sublaterally, in a large, feebly marked, subcentral annulus or solid 

 spot, and along the suture, where they are variegated with brown ; 

 narrow white scales of the strial punctures more evident than in 

 suicatult4S. Length, i. 25-1.3 mm.; width, 0.5-0.55 mm. Utah 

 (St. George), Wickham duUis n. sp. 



Species of the iimplex type, having virtually no large rounded scales on 

 the dorsal surface 12 



I 2 — Klytral striae very coarse 13 



Elylral striae fine and feeble 14 



13 — F'orm stout, notably convex, piceo-rufous, the prothorax darker ; beak 

 ( 9 ) rather long, much longer than the head and prothorax, clothed 

 basally, as well as the head, densely with rather wide decunibent 

 brown strigose scales, with a few similar white ones interspersed ; 

 antennal rhib small and slender ; prolhorax almost as long as wide, 

 parallel and nearly straight at the sides, narrowing and constricted 

 apically, convex, coarsely, deeply cribrate, clothed with narrow, dark 

 brown scales, having a few large oval ones intermingled laterally and 

 along the base ; elytra fully two fifths wider than the prothorax, a 

 fourth longer than wide, parallel, obliquely narrowing in a|)ical third, 

 the apex broadly obtuse; humeri rounded; striv coarse and very 

 coarsely punctate, rather deep suturally, becoming wholly unim 

 pressed and consisting simply of series of large punctures laterally, 

 very much coarser than in iimplrx, ihe slender scilcs from the strial 

 punctures much hncr ; slender brown scales pred.)minaiing but sparse, 

 with some a little wider and whitish at the scutellum and also on the 

 fifth interval toward the umbo. Length. 1.68 mm.; width, 0.72 mm.
