Coleopterological Notices, IV. 671 



antennae inserted a little beyond the middle, the basal joint of the funicle not 

 quite as long as the next six, club as long as the preceding five joints, rather 

 elongate, oval, densely pubescent, with the basal joint constituting less than 

 one-half of the mass. Prothorax perceptibly shorter than wide, the sides 

 straight and parallel in basal two-thirds, then broadly rounded, feebly conver- 

 gent and broadly constricted to the apex, which is three-fourths as wide as the 

 base, the latter transverse, the median lobe very small, feeble ; disk rather 

 finely and somewhat closely punctate, the punctures very distinctly separated ; 

 impunctate line feebly defined ; apical margin polished and impunctate for a 

 short distance throughout the width. Elytra distinctly wider than the pro- 

 thorax and a little more than twice as long, elongate, hemi-elliptical in out- 

 line, the apex with a feeble sutural notch, the humeral callus long but not 

 prominent ; disk moderately striate, the intervals flat, confusedly, coarsely 

 punctate when denuded. Prosternum deeply impressed along the middle, 

 rather narrowly separating the coxae as usual. Fifth ventral segment with a 

 small impressed and denuded median area, the last three segments rapidly 

 ascending in the female type, convex, and, at the extreme apex, retracted 

 above the plane of the elytral apices. Length 3.6 mm. ; width 1.4 mm. 



Texas. 



A single specimen, which appears to be a female, the abdomen 

 being entirely devoid of median impression toward base. The 

 species is allied to squamolineatus , but is easily distinguishable by 

 the dense crust of scales, and the much finer denser punctures and 

 conspicuous squamules of the pronotum. 



5 Barinus difficilis n. sp. — Elongate-oval, convex, black, shining, 

 the legs rufous ; vestiture dense, consisting of large close-set scales, pale brown 

 in color but gradually white in basal half on the second and sixth intervals, 

 and also on the fourth very near the base, also broadly white and dense at the 

 sides of the pronotum and on the under surface toward the sides, but with a 

 large subdenuded spot on the prothorax just before the mesosternal side- 

 pieces, which is sparsely clothed with long slender squamules ; median parts 

 of the pronotum rather sparsely clothed with very long, wider and narrower, 

 brown scales, which are conspicuous. Head finely, sparsely punctate, gla- 

 brous, the eyes margined anteriorly with an abrupt line of coarse scales ; im- 

 pression feeble but distinct ; beak glabrous, thick, strongly arcuate and 

 densely punctate toward base, much shorter than the prothorax, the basal 

 joint of the antennal funicle distinctly shorter than the remainder ; club 

 moderate. Prothorax not quite as long as wide, the sides parallel and nearly 

 straight to apical third, then broadly rounded and moderately convergent to 

 the apex, the constriction almost completely obsolete ; disk coarsely, deeply 

 and closely punctate, the punctures not in actual contact ; median impunc- 

 tate area fusiform. Scutellum moderate, quadrate, tumid, not deep-set, gla- 

 brous but squamulose at the sides. Elytra slightly wider than the prothorax 

 and a little more than twice as long, elongate hemi-elliptical, the sides becom- 

 ing parallel toward base and very feebly constricted at apical fourth ; humeri
