Coleo2:)terological Notices, III. 59 



slightly blunt, not prominent, the basal broadly obtuse ; sides parallel, broadly 

 arcuate or subangulate just before the middle, very feebly sinuate just behind 

 the apical angles, feebly convergent and nearly straight to th(! base ; disk 

 evenly convex, very minutely, sparsely punctate. Elytra about two and two- 

 thirds times as long as the prothorax, and, in tlie middltj, one-half wider than 

 the latter, about twice as long as wide ; sides broadly arcuate ; humeri not at 

 all exposed; apex acutely angnlate; disk strongly declivous behind, deeply 

 sulcate, the ridges strongly convex and shining, each with a single rather 

 uneven series of small, moderately distant punctures, the intervals as wide as 

 the ridges, deep, opaque, each with a single series of rather small, close-set, 

 asperate punctures. Legs slender, the femora shining, rather finely but 

 strongly punctate, the ant(!rior alone with a strong acute tooth near tlie 

 apex ; tibise strongly rugose except toward base, the spurs of the anterior 

 small, acute and nearly equal. Presternum with the apex slightly retlexed, 

 acute and tuberculiform. Length 16.0 mm, ; width 0.6 mm. 



Texas. 



A single specimen from the Levette cabinet. This species has 

 but little affinity with any other thus far described, the prothorax 

 being nearly similar to that of (jentilis and the elytra deeply sulcate, 

 as in the typical hinpilabriH; for the present it may be placed just 

 after the latter in our lists. 



£UJLABIS Esch. 

 The species of this genus may be distinguished as follows: — 



Pronotum bicarinate ; body glabrous Ibicai'iiiata 



Pronotum not at all carinate. 



Elytra finely but strongly costate ; eyes very short and transverse, occa- 

 sionally almost divided. 



Body sparsely pubescent pilbescens 



Body glabrous. 



Prothorax much narrower than the elytra, coarsely, de«!ply x>iinotate, 



the punctures not at all longitudinally confluent gl'ossa 



Prothorax subequal in width to th(^ elytra, generally more finely punc- 

 tate and longitudinally rngulose. 

 Antennae witli the second joint much smaller than any other. 



Antennj« long and extremely robust, the tenth joint twice as wide 

 as long ; punctures of the elytral series very coarse. 



laticornis 

 Antennae shorter, moderately stout, the tenth joint less tiian twice 



as wide as long; elytral punctures fine crassicoi'iiis 



Antennae with the second joint subequal to tlie fifth ; smaller sjiccies. 



I'llfipCS 



Elytra not distinctly costate, having series of lineate punctures ; eyes mucli 



longer and less deeply emarginate 0l>SCUra
