Zascelis oblonga n. sp. Oblong, form of irrorata, dark brown, dull, sparsely clothed with dull white, slim, erect hairs, with more erect short black setae intermixed. Rostrum very coarsely cribrate, at base slightly expanded, forming alae over the scrobes. Head coarsely and deeply perforate punctate. Thorax a little wider at base than long, sides obliquely convergent at apical third, posteriorly parallel, disc moderately coarsely, deeply and closely punctate, with faintly indicated median carina. Elytra wider at base than the thorax, disc not depressed, striae with deep quadrate punctures, intervals flat, the third and fifth finely carinate, rather roughly punctate. Body beneath coarsely, closely and equally punctate. Femora not toothed, tibiae serrate. Length, .18-.22 inch.; 4.5-5.5 mm. Allied in its vestiture to serripes, but in form to irrorata. Is much less robust and with less coarsely toothed tibiae than the first, and differs from the second in vestiture and the absence of femoral tooth. Two specimens. Arizona, Sierra San Lazaro.
