EXOPHTHALMINI. 101 



transverse impression. Eyes large, round, moderately prominent. Scrobes 

 narrow, deep, nearly straight, passing immediately beneath the eyes. 

 Antennae moderately long, scape gradually clavate, passing the posterior 

 margin of tlie e3^es ; funicle 7-jointed, 1-2 longer, sub-equal, 3-7 shorter, 

 sub-equal; club oval. Thorax oval, narrower in front, truncate at apex, 

 feebly bisinuate at base. Scutellum distinct, moderate. Elytra oblong oval, 

 wider than the tliorax, emarginate at base, humeri moderately prominent, 

 obtuse. Intercoxal process of abdomen broad, sub-truncate ; second seg- 

 ment of abdomen longer than the two following together, separated from 

 the first by an arcuate suture. Anterior and middle tibiae mucronate at tip, 

 and denticulate within, hind tibiae fimbriate within. Surface partially 

 scaly. 



L. floridanus, n. sp. 



Form oblong, oval, color black, shining, surface with white scales, very 

 sparsely placed, condensed in small round patches on the elytra. Head 

 and rostrum slightly longer than the thorax, black, sliining, moderately 

 densely punctured, and with white scales very sparsely placed. Antennae 

 brownish, sparsely hairy. Thorax oval, narrowed at apex, slightly broader 

 than long, sides arcuate, base slightly narrower and feebly bisinuate ; disc 

 moderately convex, densely, and rather coarsely punctured, rugulose at 

 the sides, surface black, shining, with whitish scales very sparsely placed. 

 Scutellum smooth, shining. Elytra oblong, oval, base emarginate at 

 middle ; disc moderately convex, and with rows of large, moderately deep 

 punctures, rather closely placed, the third and fourth somewhat irregular 

 at the declivity ; surface black, shining, sparsely punctured and with white 

 scales very sparsely placed, becoming condensed in small round spots, 

 distantly placed on alternate intervals. Body beneath black, shining, 

 sparsely punctured and with very few scales. Legs black, sparselj^ seal}'. 

 Length .26 inch ; 6.5 mm. 



This species is of the size of L. Mspidus Gyll. (Cuba) and of very 

 similar ornamentation. The thorax is, however, narrower at base, eyes 

 more prominent and vertex more convex. 



One specimen, Florida. 



Group II. omliei. 



Rostrum longer than the head, narrower, quadrangular, and slightly 

 dilated in front. Genae feebly emarginate. Thorax truncate at apex and 

 base. Elytra not wider than the thorax, feebly emarginate at base, humeri 

 either very oblique or broadly rounded. Articular surfaces of hind tibiae 

 very feebly cavernous. 



The differences between this group and the preceding are feeble, and 

 with other genera would probably be united with it. 



Two genera are at present known to me, one only native. 

 Second segment of abdomen not longer than the two follow- 

 ing together, first suture nearly straight. Second joint 

 of funicle short OMILEUS.
