HEMICREPIDIUS. 485 



Three examples. This small species is closely allied to H. flavipes, from which it 

 differs in the greatly produced and strongly divergent hind angles of the thorax and the 

 shorter third joint of the antennae. As in H. patruelis, &c, the thorax is differently 

 coloured in the two sexes.

<?, Asaphes flavipes, Cand. Monogr. Elat. iv. p. 219 l . 

 Hab. Mexico x , Zacualtipan in Hidalgo (Hoge). 



This small species has been found in plenty at Zacualtipan. The type is a male, 

 with the legs entirely flavous. The female, of which we have received three specimens, 

 has the anterior and lateral margins and the hind angles, or the anterior and hind 

 angles, of the thorax testaceous, and the elytra testaceous or fusco-testaceous, with 

 the suture darker. The male is black or brownish black. The legs vary in colour 

 from flavous or testaceous to piceous, being usually piceous in the male. The thorax 

 has the sides less parallel and more constricted behind in the female, the hind angles 

 appearing more divergent ; it is much more coarsely punctured in some specimens than 

 in others. The third joint of the antenna? is a little longer than the second. The 

 scutellum is thickly punctured, convex in front, with indications of a smooth median 

 line. The elytra are rounded or feebly subtruncate at the apex. Our specimens vary 

 from 5-6 millim. in length. 



13. Hemicrepidius amitinus. 



Elongate, rather narrow ( S ), moderately broad ( 2 ), shining ; black ( S ),— entirely ferruginous, or ferrugineo- 

 testaceous, with a transverse patch on the head behind, and the prothorax, except along the basal, lateral, 

 and apical margins, piceous ( ? ) ; the legs piceous in the male, testaceous in the female ; above and 

 beneath sparsely and finely pubescent, the pubescence fusco-cinereous above in the male, paler in the 

 female. Head thickly punctured, flattened in front ; antennas extending to a little beyond the hind 

 angles of the prothorax in the male, slightly shorter in the female, joint 3 distinctly longer than 2. 

 Prothorax longer than broad, a little narrowed in front, the sides feebly rounded in the female, straighter 

 in the male, and slightly sinuate behind ; the hind angles feebly divergent, not carinate ; the surface 

 thickly, finely punctate, canaliculate behind. Scutellum rather convex in front, closely punctured, with 

 indications of a smooth raised median line. Elytra two and three-fourths longer than the prothorax, and 

 wider than it, narrowing from the basal third, subtruncate at the apex, the sutural angles feebly mucro- 

 nate ; punctate-striate, the interstices flat or feebly convex and rugosely punctured. Beneath sparsely 

 punctate. 



Length 7-8|, breadth 2-2| millim. ( <5 $ .) 



Hab. Mexico, Zacualtipan and Eeal del Monte in Hidalgo (Hoge). 



Four males and two females. Closely allied to H. flavipes, of which it is perhaps 

 an extreme form, but much larger, more robust, and more elongate, the females 

 differently coloured (the head being black and the suture infuseate in the corresponding 

 sex of H. flavipes). From similarly-coloured specimens of H. instabilis the present 

 species may be known by the less elongate thorax, the hind angles of which are not 

 carinate, the rather more convex scutellum, &c.
