222 GEO. H. HORN, M. D. 



Female — Antennal club shorter than the fuincLilu.s. Pygidiiim 

 nearly as long as wide, less convex than in the male and more nearly 

 oval. 



Variations. — As stated the color varies from dark purplish- 

 brown to rufotestaceous. As far as I have seen the very dark speci- 

 mens are always females. The pale males resemble ephUlda in color, 

 are rufotestaceous, the head and thorax somewhat darker. The 

 pruinosity of the surface is very feeble, easily removed and not 

 visible in the pale specimens. 



While this species belongs very evidently in this group, the fixed 

 spur of the male hind tibia is moderately long, the free spur is long 

 and slender. In the female both spurs are long and slender. This 

 species aflbrds an instance of the necessity which often (occurs in 

 systematic work, where one character nuist be rejected which points 

 in a direction opposite to the indication of all other characters. 



Occurs in Florida. Dr. LeConte gives New York as the habitat 

 of his types, but this is undoubtedly an error. 



8. L(. geiierosa n. sp. — Oblong, parallel, moderately robust, chestuut-brown 

 moderately shining ; surface slightly pruinose. Clypeus feebly emarginate, 

 maro-iu reflexed, very narrowly at the .sides, punctuation coarse and clo.se, quite 

 dense at the middle of the front. Thorax narrowed in front, sides parallel 

 behind, margin coarsely serrate; surface coarsely and rather closely punctate, 

 median line smooth, a distinct depression iu the front angles. Elytra with punc- 

 tures coarser than the thorax and rather more closely placed, except on the de- 

 clivity : surface slightly rugose, the discal co.stie very feeble. Pygidium sparsely 

 punctate, a median smooth space which becomes broader to the apex. Metaster- 

 num densely punctate, the hair long and dense. Abdomen very si)arsely punc- 

 tate. Claws feebly curved, the tooth rather long and slightly intramedian. Last 

 joint of maxillary i)ali)i fusiform, slightly flattened externally. Length .75 inch ; 

 19 mm. 



Male. — Antennal club as long as the stem. Abdomen flattened 

 at middle, penultimate ventral with a short arcuate elevation near 

 the posterior border (fig. 36). Last ventral with a moderately deep, 

 distinctly circumscribed concavity, smooth at bottom. Inner spur of 

 hind tibia short. 



Of this species but one specimen is now before me. It resembles 

 latifrons in form, and has a color similar to that species. It seems to 

 have been sent to Dr. LeConte as uniformis Bl., at least s^jccimens so 

 labelled are in his cabinet, but the description as well as notes made 

 by Dr. LeConte show that unifonnls is synonymous with ephiUda. 



One specimen, Texas.
