KEVISION OF ELEODIINI BLAISDELL. 255 



apical angles acute, very prominent anteriorly, and distinctly everted ; 

 basal angles acute and prominent. 



Scutellum strongly transverse, broadly rounded behind, highly 

 polished, and impunctate. 



Elytra at base broadly, feebly emarginate and about as wide as the 

 contiguous prothoracic base; humeri obtuse, but not rounded nor 

 prominent; sides evenh^ arcuate, the elytra gradually narrowed and 

 acute at ajjex ; disc widest at the middle, Avhere it is rather more than 

 one-third wider than the prothorax, feebly alutaceous, finely, sparsely 

 punctate, the punctures nearl}^ simple, arranged in widely distant, 

 rather feebly defined, unimpressed rows, the intervals with a few 

 widely distant and nearly similar punctures. 



Legs rather short and slender, the anterior femora with a short 

 obtuse tooth near the outer third; middle and hind femora simple; 

 spurs of anterior tibiae moderate in length, slender, similar, and very 

 nearly equal. 



Measm^ements. — Length, 19 mm. ; width, T.8 mm. 



Forma robusta. — Very robust, elytra less narrowed toward base, 

 prothoracic base wide, integuments very smooth and subalutaceous; 

 punctuation very fine or obsolete. Prothorax comparatively large, 

 apex arcuate at middle and sinuate laterally ; sides more or less sinuate 

 before the base. Antenna? and legs quite stout to somewhat slender. 



Measurements. — Males: Length, 24-28 mm.; width, 9-10 nun. 

 Females: Length, 22-27 mm.; width, 9-10.5 mm. 



Forma confinis Blaisdell.— (See Plate 3, fig. 13.) 



Rather robust and alutaceous, very convex. Head large; antennas 

 robust, reaching to the posterior third of the prothorax. Pronotum 

 widest just in front of the middle, sometimes at the middle, poste- 

 riorly straight, convergent and not in the least constricted or sinuate 

 in front of the basal angles, the latter obtuse. Legs moderately 

 slender. 



Measurements. — Mcdes: Length, 24 mm. ; width, 7.5 mm. Females: 

 Length, 24 mm. ; width, 8.5 mm. 



The following unique, described by Colonel Casey, may be simply 

 a form of dentipes or an aberration : 



Eleodes elegans Casey. — Moderately robust, strongly convex, 

 strongly alutaceous, the elytra moderately shining; integuments 

 nearl}^ smooth. 



Head moderate, somewhat finely, sparsely punctate. Antenna' 

 rather short but slender, not quite as long as the head and prothorax, 

 third joint about two and one-half times as long as wide, scarcely as 

 long as the next two, fourth much longer than the fifth. 



Prothorax nearly one-third wider than long; disc rather strongly 

 convex throughout, widest just before the middle, somewhat sparsely
