half wider than the prothorax, parallel, evenly rounded behind, 

 rather coarsely, evenly- and sparselj^ perforato-punctate. Length 

 5.8 mm.; width 2.2 mm. 



Arizona, — Cab. LeConte. The specimen described seems to be 

 a female, the fifth ventral being evenl}- and broadly rounded be- 

 hind, the genital segment thin, flat, coriaceous and almost circu- 

 larly rounded. 



2. R. lecontei n. sp. — Oblong-oval, stout and stronglj- convex, some- 

 what shining, pale castaneous in color, the legs and antennie throughout paler 

 and more flavate; pubescence pale, sparse but very long, erect and bristling 

 from every part, with some shorter and more decumbent hairs of the same 

 color. Head wider than long, three-fourths as wide as the prothorax, the eyes 

 at some distance from the base ; antennte slender, gradually attenuate toward 

 apex, not two-fifths as long as the l)ody, the joints elongate, the second much 

 the smallest. ProViorax three-fourths wider than long, almost evenly ellip- 

 tical, the sides parallel, evenly and strongly arcuate, and the angles all bioadly 

 rounded and obsolete; apex and base arcuate; lateral edges finely senidate; 

 disk evenly convex, coarsely and irregularly punctate, the punctures dense in 

 parts. Elytra three-foiirths longer than \\ide, slightly A\ider than the pro- 

 thorax, parallel and straight at the sides, the apex evenly rounded; sutural 

 angles right and not in the least blunt; side margins finely reflexed, the con- 

 cavity Avith a single series of more pronounced punctures; disk very coarsely 

 and deeply perforato-punctate, the punctures uneven in size and separated by 

 but little more than their own widths. Abdomen finely, sparsely punctulate, 

 the legs long and moderately slender. Length 5.8 mm. ; Avidth 2.5 mm. 



Arizona (Benson). Mr. Dunn. 



The single t^-pe before me is evidentl}' a female, the fifth ven- 

 tral being flat and ver}^ evenly rounded behind. This species dif- 

 fers from testaceus in its stouter form, relatively much larger 

 prothorax, smaller head with ver3' much smaller eyes, and in its 

 closer and coarser punctuation. 



Since this revision of the Mel^ridie was written, I have received 

 a tolerabl3' complete set of the European genera, and find that 

 there is in general but little affinity with our representatives of 

 the family, the American species being smaller, duller and much 

 less conspicuous insects as a rule. The American Dasytes and 

 Dolichosoma are evidently congeneric with the European, or at 

 any rate very closely allied, but all our other genera, including 

 Alyraeris and Eurelymis, are widely difterent from their most 

 closely related European analogues.
