and the elytra! interstices more convex. The females are separated in the Salle 

 collection under the name of Asapkes soricinus. 

 We figure a typical male from Cordova. 



6. Hemicrepidius acuminatus. 



Elongate, narrow, shining ; black or pitchy-black, the prothorax with the hind angles usually rufo-ferruginous ; 

 the elytra sometimes rufo-ferruginous at the base, in one specimen castaneous ; the antennae black, the 

 legs piceous or brown ; the under surface black or piceous, the propleurae and abdomen sometimes partly 

 ferruginous ; above and beneath sparsely and finely pubescent, the pubescence fuscous or fusco-cinereous, 

 cinereous on the scutellum and under surface. Head thickly, finely punctate, flattened in front ; antenna? 

 about reaching the hind angles of the prothorax in the female, longer in the male, joint 3 a little longer 

 than 2. Prothorax much longer than broad, very gradually narrowing from the middle forwards and 

 slightly sinuate at the sides behind ; the hind angles elongate and strongly divergent, not carinate ; the 

 surface somewhat sparsely, finely punctate and usually canaliculate behind. Scutellum feebly convex in 

 front, Elytra about two and one-half times longer than the prothorax, and wider than it, narrowing 

 from the middle, the apices acuminate and dehiscent ; rather coarsely punctate-striate, the interstices 

 more or less convex and sparsely punctured. Beneath sparsely punctate. 



Length 7|-9^, breadth 2-2| millim. ( J $ .) 



Hob. Mexico, Playa Vicente and Oaxaca (Hoge). 



Five specimens. This species may be chiefly distinguished amongst its allies by the 

 elongate, sparsely, punctured thorax, the hind angles of which are long and non-carinate, 

 the sparse pubescence, and the acuminate and dehiscent apices of the elytra. The 

 pubescence on the scutellum is whitish. In one of the two specimens from Playa 

 Vicente the elytra are castaneous. In the elongate thorax and sparse pubescence the 

 present species approaches H. patruelis, H. instabilis, &c. 



7. Hemicrepidius consobrinus. (Tab. XXI. fig. 10, $ .) 



Moderately elongate, narrow, shining ; black or piceous, the hind angles of the prothorax, the extreme base of 

 the elytra, and the margins of the propleurae rufo-ferruginous, the front of the head, the anterior angles 

 and lateral margins of the prothorax, the elytral epipleurse, the basal joint of the antenna?, and the greater 

 part of the' under surface also rufo-ferruginous in the female, the elytra testaceous-brown in this sex in 

 one specimen ; the legs pitchy-brown in the male, testaceous in the female ; above and beneath sparsely 

 and finely pubescent, the pubescence on the upper surface yellowish- or fusco-cinereous, cinereous beneath. 

 Head thickly punctured, depressed in front ; antennae about reaching the hind angles of the prothorax in 

 the male, shorter in the female, joint 3 slightly longer than 2. Prothorax very little longer than broad, 

 the sides sinuate behind and gradually converging anteriorly ; the hind angles acute and feebly divergent, 

 not carinate; the surface thickly, finely punctate, obsoletely canaliculate behind. Scutellum convex in front, 

 thickly punctured, and with indications of a smooth median line. Elytra two and two-thirds longer than 

 the prothorax, narrowing from a little below the base, slightly dehiscent and subacuminate at the apex ; 

 deeply punctate-striate, the interstices rather convex and sparsely, somewhat rugosely punctate. Beneath 

 sparsely punctured. 



Length 6-6f, breadth l^-lf millim. ( 8 $ •) 



Hah. Guatemala, Senahu in Vera Paz [Champion). 



Three examples. In the slightly dehiscent and acuminate apices of the elytra this 

 small species approaches H. acuminatus, from which it differs in having the thorax
