﻿MELOLONTHID^] OF THE UNITED STATES. 251 



sparsely covered with large punctures so placed as leave a large smooth space each 

 side of the middle. Elytra gradually widened behind, rugose and punctured, with 

 the usual faint costse, and a strongly marked submarginal one, extending nearly to 

 the base. Propygidium sparsely, towards the tip strongly punctured ; pygidium 

 strongly punctured ; abdomen punctured, more faintly in the middle ; pectus clothed 

 with moderately long yellow hair. 



The male has the club of the antennae longer than the stem ; the abdomen flattened 

 in the middle ; the penultimate segment with a semicircular curved elevation, and 

 middle fovea, and the last segment with a longitudinal broad furrow. The abdomen 

 of the female is almost uniformly punctured, the punctures of the last two segments 

 being stronger ; the pygidium is triangular, and slightly conical at tip, while in the 

 male it is broader and convex. 



This species is remarkable for the length of the submarginal elytral costa, which 

 in most species is seen only near the apex. 



30. L. obesa, ovata, convexa, castanea nitida, capite dense punctata, clypeo haud confluenter punetato, 

 reflexo, late emarginato, thorace sat dense punetato, lateribus valde rotundatis, elytris fortius punctatis 

 subcostatis, pectore flavo-villoso, antennis flavis, unguiculis dente mediocri armatis. Long. -72. 



Texas, Mr. H. Haldeman. Shorter and more ovate in form than the others of this 

 group. Head densely, clypeus less densely punctured, the latter moderately margined, 

 in front broadly emarginate. Thorax nearly twice as wide as the head, short, convex, 

 tolerably densely, but almost finely punctured ; sides very much rounded, serrate, 

 slightly fimbriate. Scutellum sparsely punctured, middle smooth. Elytra dilated 

 behind, strongly punctured, with very faint traces of dorsal costse, pygidium sparsely 

 punctured. Breast clothed with yellowish hair. Abdomen punctured at the sides ; 

 claws with an acute tooth just within the middle. 



Male with the club of the antennse as long as the stem; the abdomen broadly 

 flattened at the middle, with the anal fovea broad, extending from the last upon the 

 penultimate segment, which has a slight curved transverse elevation ; posterior tibiae 

 with the inner spur one-half shorter than the outer, fixed, straight ; pygidium 

 transverse, slightly convex. 



Female with the spurs of the posterior tibiae nearly equal, flattened, but not broad ; 

 pygidium triangular, obtusely protuberant near the tip. 



31. L. prunina, atro-purpurea, oblongo-ovata convexa, capite densissime punetato, clypeo anguste mar- 

 ginato, emargiDato, thorace lateribus serratis subangulatis, postice vix angustato, sat dense fortiter 

 punetato, elytris pruinosis, parce punctatis, subcostatis, pygidio nitido fortiter punetato, pectore parum 

 piloso, unguiculis dente longo armatis. Long. -70.
