only ohsoletely impressed at base, the angles broadlj' rounded; tempora sub- 

 parallel, lonjj; and arcuate; eyes very small, not quite as prominent a.s the 

 tempora; disk reticulate, finely, feebly punctate, the punctures granuliferous 

 only toward the sides; median line narrowly impunctate; antennae short) 

 scarcelj' incrassate, one-third longer than the head, the last joint not as long 

 as the two preceding, bisected behind the middle, somewhat acorn-shaped 

 second and third longer than the following. Proihora.r nearly as long as, 

 Avide, distinctly narrower than the head, narrowly rounded and widest near 

 the apex, the sides thence strongly oblique and feebly arcuate, becoming 

 slightly sinuate to the basal margin Avhich is distinct and defined by a fine 

 impressed line, not distinctly dilated laterally and three-fourths as wide as 

 the disk; apex broadly, stronglj' arcuate; collar very broad but short, cylin- 

 drical; disk moderately convex, somewhat SAVollen just before the basal mar- 

 gin, sculptured like the head but rather more densely, the punctures feeble or 

 Avanting in a narrow median area toward base. Elytra very short, scarcely 

 two-fifths longer than wide, one-half wider than the prothorax, distinctly 

 wider behind the middle and at apex than at base, the sides feebly arcuate; 

 humeri well exposed at base; disk flat, minutely, densely punctate. Abdomen 

 shining, finely feebly and sparsely punctate. Legs rather short and somewhat 

 stout, the tarsi short and very slender. Length 3.0 mm.; Avidth 0.85mm. 



Arizona (Holbrook). 



This species is distinguishable by its very short truncate e\y- 

 tra, and differs from every other in having the elytral pubescence 

 streaming out perpendicularl}' from the suture in basal third 

 and inner half. The exposed part of the tergum consists of a 

 very large convex, finely and sparsely punctate segment, para- 

 bolically rounded behind and having, near the base, two trans- 

 verse and densely pubescent patches nearly trisecting the width, 

 analogous perhaps to those of the Omalini or at least similar in 

 origin and purpose. The single specimen is a female, kindl}' given 

 to me by Mr. Roberts and probably collected by Mr. TTickham. 



3. T. nilbifer n. sp. — Narrow, parallel, depressed, dull, the elytra paler 

 and less dull, ])ale rufo-testaceous, the abdomen above and beneath blackish; 

 elytra more flavate, with a common scutcllar spot and another similar on each 

 behind the nuddle, blacki.sh; pubescence short, decumbent, ratherclo.se, more 

 distinct on the elytra where it is even and longitudinal in direction tlirough- 

 out. Head not quite as long as wide, truncate and feebly, medially im- 

 pressed at base, the angles broadly rounded; tempora somewhat swollen and 

 rounded, long, rather more prominent than the eyes which are very small; 

 punctvu-es very shallow, dense and tuberculiferous; epistoraa narrowly pro- 

 longed and polished; antenna; nearly one-half longer than the head, moder- 

 ately slender, feebly incrassate, joints two to six uniformly decreasing in 

 length, the eleventh bisected l)chind tlie middle, nearly as long as the two pre- 

 ceding, the tenth scarcely as long as wide. Prothorax quite distinctly narrower
