Washington State (Yakima.) Mr. Wickiuim. 



The sexual characters of the single male before me are similar 

 to those of lu't/rifulu!^, but this species may be readily <listinguishc<l 

 by the larger, longer elytra, impi-essed occii)ut and proiiotum and 

 stronger, denser punctuation of the latter. 



7. V. desertoruiii n. sp. — Narrow, subparallel and rather dei)ressed, 

 polished, dark brownish-testaceous throughout, the pubescence coar.se, sub- 

 erect and rather abundant, very remote on the head. Jfrad subquadrate, 

 nu)derately convex, broadly arcuato-truncate at base, minutely and renu)tely 

 punctate throughout, the eyes rather small, nuich siiorter than the tempora, 

 the latter parallel; antenna,' a little longer than the head and protliorax, some- 

 what thick, moderately incrassate, the penultimate joints quadrate. Prothorax 

 scarcely as long as wide, rather wider than the head, angulate and prominent 

 laterally at apical third, the sides thence broadly arcuate to the short but dis- 

 tinct collar, and broadly sinuate and convergent to the feebly tumid basal 

 margin; disk convex anteriorly, finely, rather clo.sely ])unctate, the jjuncturcs 

 as])erate toward apex. Kli/lrti jiarallel and straight at the sides, broadly, ab- 

 ruptly obtuse at apex, three-fourths longer than wide and sciircely two-thirds 

 wider than the protliorax; scutellar imi)ression feeble; humeri widely exposed 

 at base; disk rather coarsely and densely pvuictate, feebly rugulose by anteriorly 

 oblitiue light. Abdomen feebly shining, imbescent, coarsely imbricato-reticu- 

 late, very minutely, sparsely ]mnctulate. lyet/ii moderate in length and some- 

 what slender, bength "i.'^S mm.; width 0.(55 mm. 



Arizona (llolbrook). Mr. Wickham. 



The modifications of the genital segment in tlie males of this 

 group are nearly similar to those of Isctus, but the lobes art' 

 shorter and mutually more distant. The present species is rep- 

 resented in my cabinet by two specimens, and the description is 

 draw'u from the male. 



8. T. proiiiinen!^ n. sp. — Narrow, shining, pale brownish-testaceous, the- 

 vestiturc coarse, moderate in length, rather abundant and conspicuous, very 

 si)arse on the head, the elytra with erect bristles seriately arranged. Head 

 (juadrate, somewhat convex, minutely and very remotely ])unctate through- 

 out, the base arcuato-truncate ; eyes moderate, slightly shorter than the tem- 

 l>ora; antenn:e distinctly longer than the head and i>rothorax, gradually and 

 rather strongly incrassate, the penultimate joints tiuadrate. I'lothnnix I)arely 

 as hmg as wide, fully as Avide as the head, iiromiiu-nt and angulate at the 

 sides at apical third, thence broadly, semi-circularly rounded at apex with tlie
