72 THE CANADIA.N ENTOMOLOGIST. 



rather large, deep, coarse punctures, which are separated by about their 

 own diameters, but become finer and shallower at sides and towards the 

 tip. Pygidium alutaceous, not distinctly punctured, though large, sparsely 

 jilaced, shallow punctures are indistinctly indicated. Sterna coarsely, 

 not very closely, punctate; metasternal hairs extremely short and sparse. 

 Abdomen rather indistinctly and much more finely punctured. Legs 

 stout, claws arcuate. Length, 1 2.5-14 mm. 



Male : Body winged. Antennal club shorter than the funiculus. 

 Abdomen broadly, vaguely impressed at middle. Spurs of posterior 

 tibiae slender, curved, free ; hind tarsi slender, much longer than the 

 tibife. Claws not or barely perceptibly toothed. 



Female : Body apterous. Antennal club a little smaller. Abdomen 

 more convex, without median impression. Posterior tibial spurs broader; 

 hind tarsi shorter than in the male. All of the claws are toothed, 

 the tooth being short, sharp and erect, nearer the base than the apex. 



This insect occurs occasionally, crawling on the ground, at Del Rio, 

 Alpine and Marfa, Texas, during June, July and August. It belongs near 

 E. cribrosa, Lee, but is distinct by numerous characters. 



Ologlyptus, Lacordaire. 



It is well known that our common Ologlyptus anastomosis, Say, varies 

 considerably in size and outline, as well as in the distinctness of the elytra! 

 costaj. Besides a considerable series of that insect from Kansas, Colorado, 

 Texas, New Mexico and Arizona, I have in my cabinet anothe.- species 

 which seems to be quite different from any of the Mexican forms described 

 by Champion in the Biologia Centrali-Americana. It may be recognized 

 by the characters noted below. 



O. Texanus, n. sp. — Blackish, covered with yellowish scales. Rather 

 elongate, somewhat flattened above. Head covered with yellowish scales, 

 which completely conceal the sculpture, antennae much heavier than in O. 

 anastomosis. Thorax transverse, broadest at about the middle, disc con- 

 vex, bifoveate, a fine distinct median carina, which is bifurcate at base, 

 lateral margin thickened, explanate, and rather widely reflexed; the 

 anterior margin is dee])ly emarginate, the base slightly bisinuate, 

 sides very strongly rounded, more suddenly so posteriorly, a strong 

 constriction in front of the hind angles, which are distinctly acute 

 and rather i)rominent ; front angles acute, feebly rounded. Elytra 

 about as wide as the broadest part of the thorax, almost parallel to 

 a point about one-third from the tip, thence suddenly sinuately narrowed,
