sliglitly longer than the sixtli .and distinctly shorter than the fifth, the latter 

 scarcely more robust, outer joints scarcely wider than long, the eleventh robust, 

 ovoidal, rather abruptly pointed, one-half longer than wide. Prothorax nearly 

 one-fifth wider than the head, three-fifths wider than long ; sides parallel, 

 evenly and distinctly arcuate ; base broadly, feebly arcuate, angles broadly 

 rounded ; apex truncate, angles obtuse and narrowly rounded ; disk feebly 

 convex, broadly, distinctly impressed laterally and anteriorly, also with very 

 faint traces of two small basal impressions which trisect the width ; surface 

 punctured like the head. Elytra nearly one-fourtli wider than the prothorax 

 and about twice as long, very depressed ; sides just visibly divergent from base 

 to apex and very slightly arcuate; surface excessively minutely and densely 

 granulate, the recumbent pubescence not distinctly visible, the longer erect 

 hairs rather distinct, not dense. Abdomen very slightly narrower than the 

 elytra, short ; sides nearly parallel ; border narrow, deep ; surface more 

 coarsely, sparsely punctate and slightly shining. Length 1.0 mm.

In tiio typo-si)ecinien there is not tiio slightest trace of an im- 

 pressed dorsal channel on the ])r()notuni, and the record of one by 

 LeConte is an inadvertence. The elytra are distinctly paler, vufes- 

 cent, and practically uniform throughout the surface, the duskiness 

 of the base and margins spoken of in the original description being 

 not clearly evident. This is a very distinct species. 



T. palli<licoriiis n. sp. — Rather slender, piceous-black ; femora dark 

 piceous-bruwn, tibiie, tarsi and antenn.e throughout paler, brownisTl-flavate ; 

 integuments dull. Ihiid fully as long as wide, very minutely, strongly and 

 densely granulose, the punctiires not distinct ; tuberculations very small and 

 feeble ; suture very fine, shining ; eyes moderate, feebly convex, the tempera 

 about as prominent, parallel, feebly arcuate and more than one-half as long ; 

 antennre about as long as the head and prothorax, slightly robust, rather 

 feebly clavate, second joint about as long as the next two together, fourth 

 and sixth subequal, smaller than the fifth and very slightly wider than long, 

 outer joints slightly transverse, eleventh ovoidal, abruj)tly pointed, scarcely 

 more than one-thii'd longer than wide. Piotlionix slightly wider than the 

 head, three-fourths wider than long ; sides parallel and distinctly arcuate ; 

 basal angles obsolete, very broadly rounded into the base, the latter in the 

 middle more feebly arcuate ; ajtex truncate ; apical angles slightly obtuse 

 and not distinctly rounded ; disk with very faint traces of two parallel im- 

 pressions, feebly convex, obsoletely tumid along the middle toward base, ex- 

 tremely minutely and densely punctate. Elytra parallel, one-fourth wider 

 and four-lifths longer than the prothorax, excessively minutely and densely, 

 and rather strongly punctato-grannlose, the longer suberect hairs very minute 

 and I'ather sparse. Abdomen slightly narrower than the elytra, decidedly 

 narrowed toward apex ; border rather thin, moderate in depth ; surface feebly
