New Species of Heteromera. 311 



between the eyes, the punctures very elongate ; neck 

 and epistoma very sparingly and finely punctate ; pro- 

 thorax long, narrow, subcylindrical, moderately convex ; 

 squarely truncate at each extremity, with the margins 

 very finely and slightly reflexed ; somewhat closely— save 

 down the median line — and evenly punctured, the flanks 

 more sparingly so ; faintly impressed down the median 

 line, and with two ill-defined depressions at each side, near 

 the base ; scutum of the mesothorax closely punctured ; 

 scutellum large, subpentagonal, smooth, thickened at the 

 sides ; elytra elongate, narrow, flat on the discs, with a 

 slight callosity on each side of the suture, at the base ; 

 as broad again as the prothorax at the base, which is 

 somewhat arcuately emarginate, and thickened ; shoulders 

 broadly rounded, sinuous at the sides, with the edges, 

 especially towards the base, reflexed ; slightly widening 

 behind the middle, thence gradually and somewhat 

 sinuously contracted to the apex, which is pointed ; the 

 sutural margin slightly raised and thickened ; vaguely, 

 especially at the base, punctate-striate ; the sutural and 

 marginal stride meeting at the apex of the elytra and 

 enclosing the remainder ; interstices nearly flat, irregu- 

 larly punctate ; epipleural fold faintly rugulose towards 

 the base ; underside and abdomen very glossy ; finely, 

 but not closely, punctured ; legs and antennae rather 

 strongly punctured, the terminal joints of the latter very 

 finely pubescent : thighs clavate or incrassate ; tarsi be- 

 neath fringed with short spinose hairs, with others, scat- 

 tered and decumbent, above; first joint of the posterior 

 pair longer than the last. 



Hab. — Pampas of the Argentine Republic. 



It is just possible the above species may be identical 

 with the Statyra unicolor (Blanch, in d^Orbig. Voy. 

 Amer. merid. p. 199), but his description is too short 

 and vague to enable me to decide this point; judging 

 from the figure given in his work (pi, 15, fig. 2), this 

 species has the prothorax more elongate, and the callosi- 

 ties at the base of the elytra much less pronounced. 



I have recently acquired another species from Peru, 

 belonging to this group, which will not accord with any 

 genus yet published ; I hesitate to describe it as I dread 

 unnecessarily to multiply the number of genera, and 

 should be glad of assistance, by the loan of specimens 

 and otherwise, so as to enable me properly, if possible, 

 to define the limits of the genera in this interesting 

 group.
