HOLOLEPTA Payk. 



The species described below is allied to j^rinceps Lee, and is 

 therefore assignable to the subgenus Leionota. Frivceps appa- 

 renth' cannot be the same as yucateca Mars, The sexual characters 

 in the former are very feeble, as readily observable in the large 

 series before me, the male being broader and shorter than the female, 

 with longer mandibles and broader propygidium, but the groove 

 along the lateral margin of the pronotum is almost identical in the 

 two sexes.' 



H. vei'llicis n. sp. — Rather narrow, feebly, evenly convex, highly pol- 

 ished. Head without trace of frontal striae, the lateral striae near the eyes 

 very short, basal, the surface behind them coarsely punctate ; mandibles 

 short, stout, not quite as long as the head, strongly arcuate and acute at tip ; 

 mentum broadly, feebly concave, even, finely sparsely and evenly punctate, 

 deeply, subangularly emarginate ; triangular gular impression almost obso- 

 lete. Proi/iorax four-filths wider than long, the sides broadly arcuate and 

 convergent anteriorly from the middle, becoming almost parallel and straight 

 in basal half ; lateral groove rather fine but deep, slightly dilated at apex ; 

 inflexed along the basal margin to lateral sixth ; disk with a fine median stria 

 in basal two-fifths, narrowly and sparsely punctate along the lateral stria 

 especially toward base. Scutellum very small, equilateral. Elytra equal in 

 width to the prothorax, parallel, the suture less than one-third longer ; apical 

 sinuation deep, rounded ; subhumeral stria dilated, deep, attaining neither 

 base nor apex ; first dorsal deep and coarse, arcuate, scarcely attaining basal 

 third, coarsely double at base, the humeri also with a short basal stria exter- 

 nally ; second dorsal fine but deep, interrupted at basal fourth, the apical 

 part beginning rather before the point opposite the termination of the first 

 dorsal, and continuing almost to the apex. Propygidium rather sparsely but 

 very coarsely, variolately punctate laterally, the punctate areas joined along 

 the posterior margin by some very small sparse and feeble punctures ; pygi- 

 dium coarsely deeply and very densely cribrate. Anterior tibise 4-dentate, 

 the basal tooth very broadly angulate and feeble, the others strong biit not 

 very acute ; posterior tibia; with tliree large acute and spiniform teeth. Pos- 

 terior half of the presternum triangular in form, tlie hind margin evenly 

 rounded ; apical half in the form of a rather narrow, transversely rounded 

 and parallel ridge, the apex obtusely rounded. Length (exclusive of mandi- 

 bles) 11.5 mm. ; width 5.4 mm. 



Arizona. 



There appears to be no Mexican species with which this can be 

 confounded, and it is widely distinct from any form hitherto de- 



1 The measurements of length include the entire body and head, except when 

 otherwise stated.
