COLEOPTERA. 99 



connected by a distinctly rounded, transverse, and somewhat feeble ridge ; 

 antennae more than two-thirds longer than the head, slender, eighth, ninth, 

 and tenth joints sub-equal in length, increasing uniformly and rapidly in 

 width. Prothorax widest just visibly in advance of the middle, where it is 

 as wide as long, and slightly wider than the head ; sides very feebly arcuate 

 anteriorly and nearly straight posteriorly ; apex one-half as long as the 

 pronotal width, and three-fourths as long as the base ; disk very strongly 

 convex ; having a slender, medial, fusiform canaliculation attaining neither 

 the apex nor the transverse channel ; the latter is at a little more than one- 

 fourth the length from the base, nearly straight, narrow but distinct, strongly 

 and abruptly cusped posteriorly in the middle, and terminating at the sides 

 in two rather large, rounded foveae. Elytra at base distinctly wider tlian 

 the jjronotum ; sides almost parallel, rather distinctly arcuate : disk mode- 

 rately convex, very coarsely and excessively faintly impressed, distinctly 

 longer than wide, and nearly as long as the head ; sutural striae strong, 

 arcuate, lateral extremely short, broadly impressed, and rudimentary. 

 Abdomen distinctly narrower than the elytra ; sides parallel and straight ; 

 surface impunctate, broadly convex ; first three dorsal segments equal, basal 

 ones without any visible carinae. Legs rather short and slender. Length 

 0.7-0.8 mm.

The description is taken from Dr. LeConte's type, which is a 

 female. I cannot distinguish Dr. LeConte's tenuis (1. c. No. 30) from 

 this species by any characters which are worthy of mention. The 

 lateral striae of the elytra appear to be much longer and stronger in 

 some specimens than in others, and the pubescence is easily rubbed 

 from the elytra. The head is noticeably broader in the males than 

 in the females. 



The identity of tenuis with the above-described form is rendered 

 still more probable from the fact that two specimens before me, appa- 

 rently not possessed by Dr. LeConte, and collected at Tampa on the 

 same day, and therefore probably at the same spot as the specimen 

 described by him as debih's, resemble much more closely, and in fact 

 are almost exactly similar to his unique type of te7iuis from Capron. 



4. E. loilgicollis n. sp.— Form slightly robust. Pubescence of head 

 and prothorax very sparse, short, and inconspicuous, that of the elytra and 

 abdomen rather long, fine, dense, and conspicuous, pale fulvo-cinereous. 

 Color of head, pronotum, and antennae rufo-testaeeous, that of the elytra, 

 legs, and abdomen paler, more flavate, rather ferruginous. Head lar^e, as 

 long as wide ; eyes rather large, not very prominent ; genae slightly con- 

 vergent and arcuate, much longer than the eye ; base broadly and evenly 

 sinuate ; interocular surface broadly, very strongly, evenly, and, in the 

 posterior third, uninterruptedly convex, polished, coarsely, but rather feebly 

 punctate at the sides, entirely impunctate along the middle ; having at two- 

 fifths the length from the base two very small and feebly impressed rounded
