NORTH AMKRICAN COLEOPTERA. 225 



segment concave with two feebly elevated cusps within the concavity. 

 The inner spur of hind tibia entirely absent, the outer long and 

 slender. 



Female. — Antennal club shorter than the funiculus. Spurs of 

 hind tibia; slender and acute, hind tarsi distinctly shorter than the 

 male. Pvgidium less transverse. 



Variations. — Except in size this species is very little variable, 

 the color is very uniform. 



This species resembles ephilida very closely, and differs in having 

 the clypeus more distinctly emarginate. The male sexual characters 

 afford the most certain method of separating the two. 



Occurs from Pennsylvania to Florida. 



12. L.. epliilida Say.— Moderately elongate, cylindrical, rufotestaceous, the 

 head and thorax usually darker; surface moderately shining. Clypeus broadly 

 emarginate, the border reflexed ; surface moderately closely punctate, the front 

 more densely, the 9 more coarsely punctured than the % . Thorax rather short, 

 sides arcuate, narrowed in front, margin entire, the punctuation moderately 

 coarse, not dense, an indistinct fovese each side nearer the base than the side. 

 Elytral punctures coarser and deeper than those of the thorax, apparently closer, 

 the discal costse usually feeble. Pygidium % broader than long; surface irregu- 

 larly wrinkled, the punctures large and vague, of ? smoother, punctured like 

 the thorax, nearly as long as wide. Metasternum closely punctate, the hair 

 moderately long, not dense. Abdomen coarsely, not closely, punctate at the sides, 

 smooth at middle. Claws with moderate size tooth, intramedian % , longer and 

 more nearly median 9 • Last joint of maxillary palpi fusiform, almost ovate, 

 distinctly impressed. Hind tarsi similar in the two sexes. Length .55 —.75 

 inch ; 14 — 19 mm. 



Male. — Antennal club not quite as long as the stem, the funicular 

 joints nearest the club transverse. Abdomen broadly channeled, 

 penultimate segment (fig. 21) feebly emarginate at middle, a rough- 

 ened space in front of the emargination ; last segment emarginate, 

 an obtuse cusp each side of the emargination, the middle of the seg- 

 ment abruptly depressed and roughened. Inner tibial spur short, 

 outer long and slender. 



Female. — Club of antennie much shorter than the funiculus. 

 Spurs of hind tibise slender. 



Variations. — In the well developed specimens the form is nearly 

 as cylindrical as in querciis, but three specimens of smaller size from 

 Texas and Florida are more decidedly ovate and resemble the females 

 of glbhom. In sculpture there is the usual variation in the distinct- 

 ness of the costiB, and some specimens are slightly more rugose.
