ELEODES ACUTANGULA 225 



Legs somewhat short and moderately stout, rather densely sculp- 

 tured. Tarsi similar in the sexes, plantar grooves open throughout. 



Male. Narrower and more elongate ovate, somewhat less convex. 

 Abdomen slightly oblique to the sterna and noticeably flattened ; tibial 

 spurs short. 



Female. Broader, more elongate oval, elytra more convex ; 

 abdomen horizontal and more convex. 



Measurements. Length (Types), 14-15 mm.; width, 5-6 mm. 



Holotype, male, and allotype, female, in my own collection. Para- 

 types in that of Mr. Ralph Hopping. 



Type locality. Dry Lake, Klamath National Forest. Collected on 

 September 17, 1912, by Mr. Ralph Hopping. 



The elytral sculpturing in corvina is almost like that observed in 

 Eleodes cuneaticollis Casey, but more coarsely punctate centrally and 

 more distinctly tuberculate laterally. Papillosa Blais., a closely related 

 congeneric species, is larger and more elongate, the elytral tubercles are 

 rounded, distinct, shining at their summits and not intermixed with 

 rugae ; in granulata Lee. the surface is more opaque and the elytral 

 tubercles are rather elongate, while in the variety obtusa Lee. the sculp- 

 turing is more eroded and dull, with the body form more like that of 

 corvina, but in the latter the elytral sculpturing is distinctly punctato- 

 tuberculato-rugose. The sculpturing of vandykei Blais. is much less 

 developed and more of the muricato-punctate type, while in its race 

 parvula Blais. the size is smaller, the pronotum more quadrate, and the 

 elytral tubercles are evident, variable in number and more or less 

 muricato-tuberculate. 



Eleodes acutangula, new species. Form oblong-oval and moder- 

 ately convex as in scabricula Lee. Color black and quite opaque. 



Head rather less than one-half as wide as the pronotum, feebly 

 convex with broad and very shallow impressions within the antennal 

 convexities ; rather coarsely and irregularly punctate. Antennae about 

 attaining the pronotal base, outer joints feebly compressed and slightly 

 wider. 



Pronotum distinctly opaque, widest at middle and transverse ; apex 

 broadly, evenly and moderately emarginate in circular arc ; sides quite 

 evenly and broadly arcuate, straighter posteriorly to base, margin more 

 or less feebly reflexed ; apical angles quite prominent anteriorly and 

 rather acute ; basal angles obtuse, distinct and slightly prominent laterally 

 on account of the basal bead. 



Elytra oval, opaque, sculptured as in consobrina Lee., but somewhat 

 coarser, that is, rather coarsely punctate centrally and granulate-
