 L. '6\ mill. 



Cylindrical, short and robust, wholly black ; the head 

 convex, evenly not thickly punctured ; tlie thorax little pro- 

 minent over the neck, rounded off at the sides, punctured like 

 the head in front and on the sides, with an antcscutellar 

 impression in wliich the jHinctures are larger and closer, the 

 lateral margin is a little raised and the stria within it well 

 marked and a little incurved towards the base ; the elytra 

 clearly punctured like the thorax, with the smooth basal

 the pygidium on its convex surface are ocellately punctured, 

 punctures not closely set, the apex of the pygidium is feebly 

 concave and distinctly rugose ; the prosternum — anterior 

 edge with a marginal stria, somewhat closely and a little 

 rugosely punctured, base with a triangular impression seen in 

 certain lights, keel without stri« ; the mesosternum anteriorly 

 obtusely produced, marginal stria fairly well defined but not

Teretriosoma Hornn, Lew. 



The pilosity on the first joint is apparently a male character 

 in the genus. Sclmiidt first noticed tliis, and Dr. Horn tells 

 me that two of his specimens of the above species have a hairy 

 first joint and in three of them it is smooth ; when the hairs 

 are absent Dr. Horn adds tlie specimens (presumably female) 

 have the angle of the pygidium less acute. This sexual 

 character should be borne in mind when the females, at 

 present unknown, are discovered of T. pilicorne, Lew., and 

 T. plumicorne, Lew., and otliors.
