UHLER ON INSECTS. 377 



humeri, the angles rectangular, the humeri a little prominent. Head 

 bluntly rounded, radiately, not very distinctly, wrinkled on the cheeks, 

 with a deep indentation each side anteriorly, and a shallower, wider one 

 next each eye; margins abruptly recurved, the subuiargin grooved, set 

 with close, minute teeth and slender bristles ; the tylus reaching to the 

 front, the lateral lobes not quite meeting in front of it, its sides almost 

 straight and parallel. Basal and second joints of the antennce slender 

 and very short, the first not reaching to the margin of the head ; the 

 third joint enlarging toward the tip, a little shorter than the fourth ; 

 fourth and fifth longer, subequal, thicker, long-oval. Eostrum of mod- 

 erate length, the basal joint almost as long as the head, a little shorter 

 than the bucculfe; the bucculte of moderate width, tapering posteriorly, 

 a little wider in front; second joint compressed, a little arcuated, long- 

 est ; third joint less robust and shorter than the second, but longer than 

 the apical one ; the apical very slender, acute at tip. Ostiolar canal less 

 than half the length of the episternum, placed next to the suture, ligu- 

 late, a little raised, before the apex obliquely impressed ; the apex scale- 

 like angular, acute. Legs moderate, the anterior tibife moderately com- 

 pressed, the exterior margin armed with about seven teeth. Scutellum 

 depressed, a little longer than wide, narrow at tip and distinctly con- 

 tracted, the apex bent down. Corium wide, with two grooved lines on 

 the outer side of the discoidal area, the inner of which is arrested be- 

 hind the middle, the posterior margin a little oblique, subtruncated, 

 costal margin strongly arcuated, its base remotely ciliated; epipleura 

 long, wide at base. Margins of the venter remotely ciliated. 



H. congruus, new sp. 



Light rufo-castaneous, polished, shining, remotely and slenderly cili- 

 ated on the sides of the head, pronotum, corium, and abdomen ovate, mod. 

 erately flat above. Head almost flat, each side of the tylus with at least 

 three oblique grooves, which define intervening, not very distinct, wide 

 wrinkles ; pits each side, anteriorly, deep, distinct, moderately large, 

 those next the eyes large and shallow ; impressed line each side of tylus 

 deep and well defined, contracted near the middle ; the surface not appa- 

 rently punctured ; ocelli small, placed very far back, and near the eyes, 

 a depression between them and the eyes ; the eyes rather flat, some- 

 what deeply seated, the margin in front of them prominently recurved. 

 Antenn.ne, rostrum and tarsi pale ferruginous, or ochreous-yellow, the 

 joints of the former moderately short, the second joint very short. Kos 

 trum reaching to the intermediate coxre, the apical joint very slender. 

 Pronotum subquadrate, a little wider than long, the sides straight, a 

 little narrowing toward the front, the edge recurved, the anterior angles 

 a little protracted, the margin exterior to them curved inward ; surface 

 moderately flat, remotely punctate on the transverse line and behind 

 it, and on the sides, more particularly next the anterior angles; the 

 disk anteriorly with one or two shallow pits each side ; the anterior
