This small species may l)e distinguished by the minutely gra- 

 nulate head and thorax and the very line punctuation of the 

 latter, that of the head being scarcely percepti1)le ; whether a 

 single specimen with much more distinct costate elytra and 

 extremely close punctuation, represents the female of the present 

 species 1 am unable to say, but it is probable , since all other 

 cliaracters agree ; there are four specimens before me. The spe- 

 cies can scarcely be distinguisiied from some Central American 

 forms notaldy T. ikwcp punctata. Crotch, excejit in the want of a 

 short row of jtunctures at each side near the basal margin of 

 the thorax.

 above piceous, the basal joints of the anteimae and the tarsi 

 paler, head impunctate, thorax minutely })unctured and granu- 

 late, elytra deeply and regularly punctate-striate, tlie interstices 

 longitudinally costate and minutely punctured.
