two fine discal costules, the humeri right, not blunt, the apex of the 

 angle thickened, notably reflexed and laterally exposed; abdomen 

 shining, very finely subrugulose and with very feeble scattered 

 asperulations, the last two segments asperately punctate, with the 

 interspaces minutely, closely punctulate; prosternum much less 

 closely and less coarsely punctate throughout than in wa.ro. 

 Length (9) 13.0-15.0 mm.; width 5.4-6.9 mm. Texas. 



eximia n. sp. 



4 Reflexed sides of the elytra very short, not extending from the humeri 

 a distance greater than a fourth the length of the prothorax, broadly 

 rounded externally and auriculiform. Form elongate, the surface 

 strongly shining; head strongly impressed, coarsely, moderately 

 closely punctate, gradually more finely so posteriorly; antennae 

 longer than usual, attaining the base of the prothorax (cf ) or shorter 

 (9); prothorax scarcely a fifth wider than long, parallel, the sides 

 evenly and moderately arcuate to the apical angles, which are but 

 little produced and blunt, straight or subsinuate toward the basal 

 angles; apex sensibly narrower than the base, strongly, evenly 

 sinuate, the base transverse, broadly, very feebly bisinuate, the 

 angles right and very sharp, sometimes minutely everted; surface 

 evenly and moderately convex, minutely, sparsely punctate, gradu- 

 ally rather broadly but feebly concavo-explanate and coarsely, 

 confluently punctate laterally, the edge thin; scutellum moderate, 

 triangular; elytra fully two-thirds longer than wide, one-half wider 

 than the prothorax, at base also wider than the latter, widest at the 

 middle, the sides straighter and feebly converging thence to the base, 

 strongly rounded and gradually rapidly converging posteriorly to 

 the subacute apex; surface flattened or feebly concave suturally, 

 smooth, confusedly and distinctly creased and finely, sparsely 

 punctate; abdomen nearly smooth, very minutely sculptured; 

 propleura asperato-rugulose, the prosternum smooth, finely, sparsely, 

 asperulately punctate. Length (9) 13.5-14.0 mm.; width 6.0-6.3 

 mm. New Mexico, Gissler. [Asida quadricollis Horn]. 



quadricollis Horn 



Reflexed sides of the elytra straight or nearly so, extending posteriorly 

 at least one-half as far as the thoracic length and generally much 

 further, longer as a rule though much more variable in length in the 

 male than in the female; surface lustre rather shining though some- 

 what obviously alutaceous 5 



5 Prothorax relatively very small, the hind tarsi very slender and 

 filiform, much longer in the male than in the female. Form rather 

 stout; head rather strongly impressed and also with a small impres- 

 sion on the vertex, strongly, rather closely punctate throughout; 

 antennae shorter than in quadricollis, not extending to the thoracic 

 base even in the male; prothorax a fourth or fifth wider than long, 

 parallel, the sides evenly but very moderately arcuate to the apical 

 angles, which are moderately advanced, acute and never more than 

 slightly blunt, not more than straight basally, the angles right or 

 slightly more, not prominent but sharp; apex very distinctly nar-
