and gi'adually narrowed posteriorly ; apices obtusely rounded. 

 Femora clavate ; the posterior, longer and more gradually thick- 

 ened, surpassing the elytra behind ; first joint of posterior tarsus 

 longer than the two succeeding joints combined. Front coxae 

 spherical, not angulate on the outside, their cotyloid cavities com- 

 pletely' closed behind. Intermediate cotyloid cavities open on the 

 outside. Abdomen with five visible segments, the fifth scarcely as 

 long as the fourth, and rounded at the apex. Female stouter than 

 the male, with the antennas a little shorter than the body, with the 

 eleventh joint scarcely longer than the tenth, and with joints 7 — 11 

 slightly dilated and compressed. 



Following Lacordaire's system, this genus must be 

 placed in the Callichromiuce, in which group it seems to 

 come nearest to lontJwdes. It is easily distinguished 

 from the latter by the form of the prothorax, and by the 

 scape rounded, not angulate, at its inner apical border. 



Hyixmiyra erihripennis, n. s. (PL IX., fig. 2, 3' )• 

 Niger, eljiris viridis, sub-nitidis, versus suturam purpureo- 

 cyaneis : capite punctato ; prothorace foveolato-punctato, vitta 

 utrinque, et vittis duabus obsoletis medio disci argenteo-sericeis ; 

 elytris fortiter et creberrime punctatis ; pedibus piceis sparsira 

 punctatis, femoribus quatuor anticis rufis ; antennis nigris, scapo 

 dense punctato, corpore subtus argenteo-imbescente. Long. 14 and 

 17 ; lat. 3^ and 4^ mm., ^ and ? .

Black. Head with a faint silky white pubescence ; strongly 

 enough punctured. Prothorax above with close foveolate punctures ; 

 with a few small smooth spaces ; with a distinct silvery white or 

 fulvous vitta on each side, and two almost obsolete vittae along the 

 middle of the disk. Elytra of a fine metallic green, passing to 

 purplish blue towards the suture and external margin ; covered 

 with very strong and confluent punctures, which give to them 

 a rasp-like appearance. Body underneath with a silvery pubes- 

 cence, somewhat denser in the female. In the female specimen 

 before me the legs are entirely dark brown, in the male the 

 four anterior femora are red. 



The characters of the male have been drawn up from 

 one of two specimens in Mr. Bates's collection ; those of 

 the female from a specimen in the British Museum 

 collection.
