form, size and sculpture, are not so satisfactoril}' differentiated by 

 description. 



The following group of three species is very distinct in the long 

 slender antennae, with all the joints elongate, and may be further 

 identified by the abdomen rather strongly narrowed from base to 

 apex, by the laj'ge subrectangular prothorax, with the disk perfectly 

 even and free from impressions, by the slightly sparser, finer punc- 

 tures, with the surface correspondingly more shining, and by the 

 decidedly larger size. 



T. aiiteiinariiis Fauv. — Bull. Soc. Linn. Norm., Ser. 3, Vol. II, p. 97. 



I have not been able to examine this species in nature, and the 

 characters given in the table were taken from the original descrip- 

 tion of M. Fauvel. 



T. pallidum n. sp. — Rather slender and fusiform, feebly convex, pale 

 brown ; abdomen piceous ; legs and antennae pale flavate ; integuments slightly- 

 sinning. Head about as long as wide, rapidly narrowed and triangular in 

 front of the eyes ; sides in basal half parallel ; surface subdepressed, very 

 minutely punctato-reticulate, finely pubescent ; eyes moderate, rather convex, 

 very coarsely faceted ; antennae much longer than the head and prothorax, 

 very slender, scarcely visibly incrassate, all the joints much longer than 

 wide, second shorter than the next two, fourth and sixth Slightly shorter than 

 the third and fifth, and very slightly more slender, tenth nearly one-half 

 longer than wide, eleventh slender, cylindrical, abruptly pointed at apex, 

 nearly three times as long as wide. Prothorax slightly though distinctly wider 

 than the head, about one-sixth wider than long ; base and apex subequal, very 

 feebly arcuate ; sides parallel, feebly arcuate ; apical angles narrowly, basal 

 more broadly rounded ; disk broadly, feebly convex, more strongly so near the 

 margins, even, without trace of impressions, more strongly shining, subaluta- 

 ceous, very minutely and excessively feebly punctate. Elytra about one-fourth 

 wider and two-fifths longer than the prothorax, parallel, subquadrate ; sides 

 nearly straight ; surface very feebly convex, alutaceous, excessively minutely 

 punctate, the piinctures smaller but stronger than those of the j^i-othorax, not 

 in mutual contact. Abdomen narrowed toward apex, very slightly narrower 

 than the elytra ; segments rather long ; border strong, not very deep ; surface 

 strongly alutaceous, reticulate in broken transverse wavy lines, the interspaces 

 dull. Length 1.2 mm. 



Texas (Austin 2). 



The pubescence of the anterior portion is very fine and dense ; 

 it is suberect, and is not intermingled with longer hairs as in the 

 preceding section. It belongs near anfennarius of Fauvel, but is a 

 much smaller species.
