﻿MELOLONTHIDvE OF THE UNITED STATES. 249 



The punctures of the thorax are variable, being sometimes strong and scattered, at 

 others finer and more numerous, but there is never any distinct smooth dorsal line. 

 The punctures of the elytra support very small hairs ; the sides of the abdomen are 

 punctured, more distinctly on the last two segments ; in the male the last one is 

 foveate, and the penultimate impressed in the middle, and the anterior segments are 

 slightly flattened ; the club of the antennse is not longer than the stem.

Middle, Eastern and Southern States, abundant, as far west as Kansas. The sexual 

 characters are precisely as in the preceding, except that the penultimate ventral seg- 

 ment is more deeply impressed ; the punctures of the elytra also support very small 

 hairs. I have not observed any well marked races in the species, though individual 

 differences occur in the size and closeness of the punctures of the thorax. 



26. L. lutescens, rufo-testacea, oblongo-ovata convexa nitida, capite obscuriore confertim punctato, 



clypeo emarginato, thorace fortiter parce punctato, rufescente, antrorsum angustato, lateribus rnagis 

 rotundatis, elytris subtilius punctatis subcostatis, pygidio vix punctulato, pectore longo flavo-villoso, 

 unguiculis dente longo armatis. Long. -59. 

 One male from Georgia. Related by sculpture to the two preceding, but apart 

 from color, it differs by the head being not confluently punctured, and by the thorax being 

 more convex. The club of the antennae of the male is as long as the stem ; the penul- 

 timate ventral segment is impressed with a slight oblique elevation each side of the 

 impression, the last segment is deeply foveate, and the anterior ones longitudinally 

 impressed, the last two segments are punctured, but the pygidium is only very finely 

 punctured, and the propygidium is smooth. 



27. L. c o r r o s a, castanea, oblonga, antice angustior, capite nigricante, dense conflueDter punctato, clypeo 

 tenue marginato, emarginato, thorace rude sat dense punctato, linea dorsali sublaevi, lateribus serratis 

 parce fimbriatis, elytris subtilius punctatis, vix costatis, pectore brevius flavo-villoso, tibiis posticis cal- 

 caribus elongatis, unguiculis dente acuto longo armatis. Long. -77. 



Texas ; two males collected by Mr. A. Schott, of the IT. S. and Mexican Boundary 

 Survey. Body oblong, narrower in front, shining reddish brown. Head dark piceous, 

 very densely, confluently punctured, clypeus emarginate, with a narrow reflexed 

 margin. Thorax about one-half wider than the head, scarcely one-half wider than 

 long, obliquely narrowed in front, and very slightly so behind ; sides serrate, sparsely 

 fimbriate; covered with large punctures, sometimes confluent, with an indistinct 

 smooth dorsal line. Elytra more finely punctured, with faint traces of dorsal costce ;,
