REVISION OF ELEODIINI BLAISDELL. 349 



ternal border sinuate to feebly arcuate. Apex small and triangular, 

 finely setose, tip apparently without longer setae, fossa at the base of 

 the external surface. 



Appendage short niannnilliforni, with tuft of moderately long 

 setse at tip. 



Superior pudendal inemhnuie not rugulose and attaining the apical 

 fourth of the dorsal plate. 



Basal prominences very small. 



Ventrolateral surfaces flattened centrally to base and convex later- 

 ally ; each lateral surface smooth, sparsely and finely punctate, setose, 

 setae minute, slightly concave before the apex. Submarginal groove 

 small beneath the external border of the dorsal plate, which is not 

 explanate^ apex finely setose. Internal margins of the valves con- 

 tiguous in basal two-thirds; genital fissure in apical third, not very 

 narrow and fusiform. Inferior pudendal membrane not visible. 



Habitat. — California (San Diego County; Port Harford, San Luis 

 Obispo Count}^). 



I have taken this species from old stumps at Poway, elevation TOO 

 feet; from wood-rats' nests on the hills bordering Mission Valley, 

 near San Diego, elevation 300 feet. 



Number of specimens studied, 14. 



Sexitypes and co-types in" my own collection. 



Type-locality. — Mission Valley, near San Diego. 



Salient type-characters. — Strongl}' convex, shining. Elytra scarcely 

 asperately sculptured. Pronotum strongly convex, apex emarginate, 

 sides rather strongly arcuate and constricted in basal tenth, apical 

 angles not at all rounded and somewhat prominent anteriorly, basal 

 angles rectangular. Elytra with the humeri rounded, and quite con- 

 tinuously so Avith the strongly arcuate sides; punctures rather 

 coarse, not deej), rather simple centrally and muricato-granulate 

 laterally. Abdomen very strongly and densely sculptured, last two 

 segments much less so. 



Diagnostic characters. — One of the most convex species of the sub- 

 genus Blapylis., and can not be confounded with any species, except 

 inctdta.^ hornii., consobrina, and parricollis. 



Professor Fall has very carefully compared it with types in the 

 LeConte collection and found it not to correspond with any named 

 species. 



Inculta is more robust and with the pronotum more transverse, 

 especially in the female, the integimients are duller. The prothorax 

 is not distinctly constricted at base and the abdomen is finely sculp- 

 tured. 



Neotonue is no doubt closely related to consobrina^ but can readily 

 be separated by its greater convexity, the circularly oval elytra, not
