752 Goleopterological Notices, VI. 



only obsoletely impressed at base, the angles Ijroadly rounded; tempora sub- 

 parallel, long and arcuate; eyes very small, not quite as prominent as the 

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

 only toward the sides; median line narrowly impunctate; antennte short; 

 scarcely 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. Prothorax nearly as long as, 

 wide, distinctly narrower than the head, nan-owly rounded and widest near 

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

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

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

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

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

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

 wanting 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. ; width 0.85 mm. 



Arizona (Holbrook). 



This species is distinguishable by its very short truncate el}^- 

 tra, and differs from every other in having the elytra! pubescence 

 streaming out perpendicularly 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, kindly given 

 to me by Mr. Roberts and probably collected b}^ Mr. Wickham. 



3. T. iiiiljifei' n. sp. — Narrow, parallel, depressed, dull, the elytra paler 

 and less dull, pale rufo-testaceous, the abdomen above and beneath blackish; 

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

 behind the middle, blackish ; pubescence short, decumbent, rather close, more 

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

 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 ver^' small; 

 punctures A'ery shallow, dense and tuberculiferous; epistoma narrowly pro- 

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

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

 length, the eleventh bisected behind the middle, nearly as long as the two pre- 

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