EEVISION OF ELEODIINI BLAISDELL. 335 



Apicdle triang-iilar, moderately convex above, without groove; 

 sides slightly prominent at base, thence feebly sinuate to tip, the 

 latter subacute; base with a moderate and rounded lobe at middle, 

 feebly arcuate laterally. 



Sternite transversely parabolic. Each lobe triangular; surface 

 glabrous, feebly convex, impunctate in basal third, punctate else- 

 where, more densely so about apex, setose, setae moderately long; ex- 

 ternal border obliquely arcuate; apex narrowly rounded, and con- 

 tinuously so with the internal border which becomes sinuate. Mem- 

 l)rane not setose, sinus rather broad and triangulo-oval. 



Female. — Genital segment parabolo-triangular, rather depressed, 

 dorsal surface quite plane and not noticeably setose, except at apex, 

 glabrous. 



Valmda (Plate 4, figs. 9 and 10). — Dorsal plate oblong, quite hori- 

 zontal, with the sides subparallel ; surface plane or verj'^ slightly 

 concave, obsoletely punctulate ; internal and external borders slightly 

 arcuate; apical border more or less evenly rounded, angle not in the 

 least evident. Apex triangular, rather broad, very finely setose, 

 setae at tip moderately long. Fossa at base of the external surface 

 of the apex behind the dorsal plate. 



Ajypendage short mammilliform, with a pencil of quite long setae 

 at tip. 



Superior pudendal inembrane longitudinally rugulose and rather 

 broadly exposed, attaining the apical fourth of the dorsal plate. 



Basal prominences very small. 



Ventrolateral surfaces triangularly plane at center to base ; surface 

 lines quite straight as viewed longitudinally and moderately convex 

 transversely; surface smooth and impunctate. Submarginal groove 

 well developed beneath the distinctly explanate external margin of 

 the dorsal plate, extending obliquely across the base of the apex as 

 a shallow concavity; apex finely setose. 



Internal margins of the valves contiguous in basal three-fourths; 

 genital fissure in apical fourth and rather narrowly fusiform. 

 Inferior pudendal membrane not visible. 



Hahitat. — California (San Diego County; San Bernardino Moun- 

 tains; Los Angeles County; Santa Barbara County; Fort Tejon, 

 Fuchs and Hopping; San Francisco County; Shasta and Siskiyou 

 counties). 



Number of specimens studied, 4.5. 



Type. — A male in the LeConte collection. 



Typedocality. — Mountains about Santa Isabel, California. 



Salient type-characters. — Oblong. Thorax rounded, apex emar- 

 ginate, thickly punctate, sides granulate, margin reflexed, posterior 

 angles minute. Elytra thickly and coarsely punctate, sides and pos- 

 teriorly rough and reclinately granulate, apex attenuate (LeConte).
