COLEOPTERA. 118 



Tallahassee, Florida, 2 ; Ana Arbor, Michigan, 1. 



The description is taken from one of the Tallahassee females, the 

 specimen from Ann Arbor is a male, and the only difference to be 

 observed besides the usual abdominal sexual characters, are the re- 

 markable lunate, strongly swollen middle femora, and the more slender 

 antennal club of the male. The head is if anything slightly smaller 

 in the male than in the female. The metasternal and prosternal 

 foveae are characteristic of the genus. 



16. E. decorus n. sp. — Form rather slender. Color piceo-rufous ; elytra, 

 legs aud antennae paler, tiavo-t'erruginous. Pubescence sliorl, fine, sparse 

 and inconspicuous ; integuments sliining, those of the elytra distinctly trans- 

 lucent. Head large, robust, slightly longer than wide ; posterior angles 

 broadly rounded ; eyes large, prominent, their own length in advance of the 

 posterior angles ; interocnlar surface raised far above the eyes, ilat above, 

 rapidly declivous on all sides,, most minutely and sparsely punctulate, 

 having two deeply imj^ressed circular sjiongy-pubescent foveae on a line with 

 the posterior third of the eyes, and mutually one-half more distant than 

 either from the eye ; intermediate surface feebly convex aud entire ; canali- 

 oulations rapidly convergent, very feeble and becoming obsolete anteriorly ; 

 supra-antennal tuberculations large, rounded, prominent ; intermediate sur- 

 face slightly depressed ; epistoma rather strongly and evenly rounded ante- 

 riorly : antennae very short, very slightly longer than the head, second joint 

 more robust than the first, sub-globular, penultimate joints very short, ex- 

 tremely transverse ; tenth over four times as wide as long, acute laterally, 

 eleventh very robust, ovoidal, obtusely acuminate, nearly as long as the 

 five preceding joints togetlier, very densely pilose. Prothorax widest in the 

 middle where it is slightly wider than the head and nearly one-fourth wider 

 than long ; sides thence very strongly convergent anteriorly and posteriorly, 

 slightly more strongly so in the former direction in which they are very 

 strongly arcuate, feebly sinuate in the latter ; apex distinctly shorter than 

 the base, feebly and equally arcuate ; disk moderately convex, very finely 

 rather feebly and evenly i^unctulate, having at one-fifth the length from the 

 base a deeply impressed narrow posteriorly cusped groove, cusp-point slightly 

 enlarged as a nude punctiform impression nearly attaining the base, arms 

 nearly straight laterally, terminating at the sides in two circular deeply- 

 impressed spongy-pubescent foveae. Elytra nearly quadrate, at base just 

 visibly wider than the pronotum ; sides rather feebly divergent posteriorly, 

 strongly and evenly arcuate ; together transversely truncate behind ; disk 

 moderately convex, finely rather closely and very feebly punctulate, darker 

 at the base and apex ; sutural striae fine, approximate and straight, each 

 originating in a puncture near the base just exterior to which there is a 

 second very feeble puncture, and still exterior, nearer the base and distinctly 

 nearer the humeri than the suture there is a much larger punctiform im- 

 pression which is continued posteriorly by a feeble broadly impressed ill- 

 defined stria, arcuate externally and gradually approaching the suture, 

 becoming obsolete at one-fifth the length from the posterior margin. Abdo-
