REVISION OF ELEODIINI BLAISDELL. 269 



Apjjendagc flattened, semi-ellipsoidal, comparatively large, punc- 

 tate, and strongly setose at apical moiety, setse long. 



Superior pudendal memhrane attaining the middle of the dorsal 

 plate and longitudinally rugulose. 



Basal protuheranees rather well developed. 



Ventrolateral surfaces. — Body not inflated and very feebly con- 

 cave laterally and before the apex; finely and sparsely punctate, 

 setose throughout, setse small and reclinate; inferior margin of the 

 fossa with a few rather long seta^. Submarginal groove not well de- 

 veloped, dorsal plate scarcely expanded laterally. Internal margins 

 of the valves contiguous in basal third. Genital fissure narrowly 

 fusiform, closed in basal half by the inferior pudendal membrane. 



Ilahitat. — Lower California (collection of Hubbard and Schwarz; 

 Comondu, San Jose del Cabo, San Quintin, collection of California 

 Academy of Sciences; Santa Margarita Island, March, collected by 

 Charles T>. Haines, collection of Charles Fuchs). Arizona (Charles 

 Fuchs) . 



Number of specimens studied, 12. 



Type in the Horn collection ; collected by William M. Gabb. 



Type-localUy. — Lower California. 



Salient type-characters. — INIale, thorax subquadrate, sides rounded, 

 feebh" converging at base; apex rather deeply emarginate, angles 

 acute, not dentiform, basal angles not prominent. Female, thorax a 

 third broader than long, moderately rounded at the sides, not con- 

 verging at base, apex as in the male, base notably broader than apex. 

 Elytra strongly attenuated behind, with distant rows of rather fine 

 and distinct punctures (Horn). 



Diagnostic characters. — Militaris is separated from armata by the 

 femoral teeth being less produced, broader and more equilaterally tri- 

 angular. The anterior angles of the prothorax are less prominent 

 and less strongly dentiform, everted or not. The elytra are more 

 attenuated behind. 



The insect appears more obtuse in front on account of the stronger 

 discal convexity of the pronotum. A large series would no doubt 

 show variations in the femoral teeth ; the male specimen from Santa 

 Margarita Island has the teeth more produced than those from the 

 mainland. In a single specimen from Calamajuet, Lower California, 

 all of the elytral punctures are rather coarse and very distinct, not 

 impressed and the femoral teeth approach those of armata in form. 



There is in this species a greater antero-posterior dorsal convexity 

 than is observed in armata. 



In another specimen before me the general form is that of a male 

 acuticauda — the elytra being gradually produced at apex with the 

 dorsal outline continuously arcuate ; the punctures are small ; length, 

 28 mm. ; width, 9 mm.
