196 CALLICHHOMA CHRYSOGASTER. 



reddish brown, the mandibles black at tip and margins. 

 Antennae ferruginous , covered with a minute yellow pu- 

 bescence. Prothorax black with violet tinges , above cover- 

 ed with a black , beneath with a golden pubescence. The 

 scutellum and elytra black with greenish blue tinges, den- 

 sely covered with a minute black pubescence. The legs 

 rusty red, covered with a yellow pubescence. Meso- and 

 metasternum as well as the basal half of the first abdomi- 

 nal segment violaceous black, the rest of the abdomen 

 ferruginous; the whole undersurface covered with a short 

 golden pubescence, whence I have derived the name. 



Head rather densely punctured , coarsely on the vertex , 

 irregularly corrugate behind the eyes , with curved wrin- 

 kles behind the mouth on the undersurface; behind these 

 wrinkles the head is nearly impunctate. The inter-anten- 

 nary ridge emarginate, with a narrow longitudinal groove 

 which widens a little and again narrows on the vertex; a 

 transverse impression across the face between the base of 

 the cheeks; the mandibles not elongate. The antennae stout 

 not quite extending to the end of the elytra , resembling 

 those of Pachyteria , but the scape not toothed at the top. 



Thorax distinctly longer than broad at the base, with 

 an acute tubercle or short spine at about the middle of 

 the sides, opaque in consequence of a very dense puntua- 

 tion , and with a somewhat smooth line (impressed at the 

 anterior half) along the middle of the disk; below the 

 lateral spines the thorax is impunctate. The prosternum 

 between the anterior coxae is rounded , not tuberculate. 

 The scutellum is triangular , sub-acute at the apex , pubes- 

 cent, and with a smooth impressed line along the middle. 



The elytra are somewhat elongate , very slightly taper- 

 ing in a concave line to the end, the apices separately 

 rounded; they are opaque in consequence of the dense 

 punctuation and pubescence, with the exception of a nar- 

 row sutural edge and a costa extending from the shoulder 

 down to a little before the apex which are destitute of 

 hairs; traces of a somewhat shorter costa may be obser-
