one-fourth shorter than 3d or 5th. Prothorax a little longer than 

 wide, oval, broadly rounded on the sides, feebly constricted at 

 the base, which is truncate ; disk densely punctured, with a 

 small median smooth spot in 9 , more finely punctured with a 

 longer dorsal smooth stripe in % , and with a feeble dorsal im- 

 pression and obsolete cicatrix each side of the median line. 

 Elytra elongate, parallel, rounded at tip. Presternum very 

 narrow and nearly invisible between the coxae, but not prolonged 

 behind ; front coxae transverse, widely angulated externally ; 

 mesosternum broadly truncate behind, coxae open externally ; 

 episterna of metathorax wide in front, and narrowed almost to a 

 point behind, as in Oeme. Legs slender, thighs feebly clavate, 

 hind tarsi as long as the tibiae, 1st joint longer than two following 

 united. Ventral segments nearly equal in 9, 1st longer in % ; 

 5th shorter in % than 9 , and broadly rounded at tip. 



A slender brownish insect, without conspicuous characters, 

 resembling somewhat a very narrow Callidium ; the antennae in 

 the 1 are as long as the body, in the 9 about two-thirds as long. 



491. H. testaceus. Elongatus, testaceus, subtiliter pubescens, an-

 paulo longiore, lateribus late rotundatis, postice subconstricto ; elytris 

 subrugosis, punctulatis, et parce punctatis. Long. 9 — 14 mm.

 the eyes being less deeply emarginate than in the other genera 

 of the group, and scarcely embracing the base of the antennae, 

 which are inserted on a line with their front margin.

One female ; Texas. Of the same form as A. surinamum, but 

 smaller ; uniform brownish-testaceous, thinly clothed with long 

 pale hairs ; the head and thorax are coarsely punctured, the 

 punctures of the latter are not deep, but so close as to produce a 

 reticulate appearance, and in the centre of each puncture is a
