elytra with a very feelile depression below the base, the shoulders 

 prominent, the surface very finely and closely punctate-striate near 

 the suture, the sides more strongly punctured and slightly rugose

Rah. R. Argentine. 



Of this species I have received several specimens from 

 Mons. Clavareau labelled with the locality given above. 

 The description is that of the male which is of purplish 

 colour above, and differs from any other Aghalns in the 

 sculpturing of the thorax and the fine and close punctua- 

 tion of the elytra, also in having the posterior tibise with 

 a short tooth only, instead of a longer spine. The female 

 does not differ except in the absence of the tibial tooth 

 and in the blue colour of the upper surface. 



Coyticra wnca, sp. n. 



Obscure aeneous, the antenn* and legs testaceous, thoi'ax very 

 minutely and closely punctured, elytra much more strongly 

 punctured, the punctures semi-regularly arranged near the suture 

 only, the interstices transversely wrinkled.

Of elongate, parallel shape and of pale seneous, subopaque colora- 

 tion, the head very finely and sparingly punctured, clypeus separated 

 from the face by a triangular groove, more strongly punctured, its 

 anterior edge deeply triangularly emarginate, labrum flavous, antennaj 

 slender and filiform, pale fulvous or testaceous, third and fourth 

 joints equal, elongate, terminal joints slightly thickened; thorax

 and closely punctured, the punctures arranged in indistinct rows 

 near the suture, very irregularly on the rest of the disc, the 

 interstices irregularly wrinkled and longitudinally costate at the apex, 

 the shoulders prominent, followed Ijy a feeble longitndinal ridge wliicli 

 extends nearly to the apex ; below piceous with a bluish or aeneous 

 lustre, the legs testaceous, the presternum rather broad, slightly
