49. L. parvidens, ferrugineo-fusca, subpruinosa, sequaliter punctata, pube flava erecta in thorace et ad 

 elytrorum basin longiore vestita, pectore longe villoso, unguiculis dente brevi armatis. Long. '77. 



One male from Georgia. Closely allied to the preceding ; the thorax is finely punc- 

 tured, convex, slightly narrowed towards the base. The elytra are finely punctured, 

 with the sutural ridge well defined, not wider than usual ; the dorsal costse are very 

 faint : the margin is not fringed, and long hairs are seen only towards the base. The 

 club of the antennae is as long as the stem, and the abdomen is not impressed. The 

 posterior and middle tarsi are imperfect, but the anterior ones are armed only with a 

 short acute tooth. 



50. L. r u b i g i n o s a , ferrugineo-fusca, subpruinosa, thorace longe minus dense villoso, brevi, subtilius 

 punctato, postice haud angustato, elytris subtilius punctatis, breviter pubescentibus, pilis longis parcis 

 versus basin interrnixtis, margine fimbriato, pectore longe villoso. Long. -65 — -76. 



Texas, at New Braunfels, collected by Mr. Lindheimer. Body oblong, slightly 

 ovate, convex; above of a brownish red, with a grayish lustre on the elytra. Head 

 densely, thorax finely punctured, clothed not very densely with long soft erect yellow 

 hair ; the thorax is short, and is not narrower at the base than at the middle. The 

 elytra are finely punctured, not costate, but with the sutural ridge broader and less 

 elevated than in the others; the surface is thinly clothed with short yellowish hair, 

 with longer hairs intermixed especially towards the base ; the margin is fringed : the 

 pygidium is moderately punctured : the breast is covered with tolerably long dense 

 hair. 



In the male the club of the antennas is as long as the stem and the abdomen has a 

 scarcely perceptible anal impression : the spurs of the posterior tibige are free in both 

 sexes. 



a- In one male specimen of a more cylindrical form there is a bifurcating oblique 

 elevated line each side of the penultimate ventral segment, but in the other specimens 

 I cannot perceive any vestige of such ornament. Subsequent collections may show 

 the propriety of regarding it as a separate species, for the sutural ridge is more strong- 

 ly marked, and somewhat narrower. I would hesitate at present to give it as distinct, 

 as no other difference in sculpture can be perceived. 



Group XIII. 



Consists of pruinose species, glabrous above, having 10-jointed antennas, and not 

 emarginate penultimate ventral segment. The head is comparatively large and the 

 clypeus is strongly margined, hardly sinuate in front. The mandibles project strongly ; 

 the last joint of the maxillary palpi is slightly oval, not impressed. The thorax is 

 rounded on the sides, not narrowed at the base. The breast is tolerably densely 

 clothed with long hairs ; the tarsi are long and the ungues are toothed near the base. 



In the males the club of the antennas is nearly as long as the stem ; the penultimate
