deeply emarginate, three-fourths as ^vide as the base, the latter broadly lobed 

 in the middle, feebly sinuate laterally, the basal angles not as prominent a>5 

 the median lobe ; sides rather strongly, evenly arcuate ; disk rather coarsely 

 and densely punctate throughout. Scutellum highly polished. Elytra but 

 very slightly wider than the prothorax and much more than three times as 

 long ; sides very feebly arcuate ; apex acutely rounded ; disk with coarse 

 shallowly excavated grooves, which are coarsely deeply and perforately punc- 

 tured, the punctures generally separated by less than their own diameters ; 

 intervals equal, very feebly convex, rather finely, not very sparsely punctate. 

 Abdomen sparsely but rather coarsely punctate, especially tovvard base, the 

 pubescence rather fine, short and sparse. 



Alule. — Anterior tarsi robust but scarcely at all dilated, the first joint not 

 tufted beneath, second with a single small tuft of fine yellowish pubescence, 

 third with two similar tufts arranged transversely ; intermediate tarsi not 

 modified. 



Length 5.G-6.3 mm. ; width 2.7-3.1 mm. 



Texas. 



A considerable series of this distinct species is before me, collected 

 at various points in Texas, and among them are several examples 

 taken at Columbus by Mr. Schwarz. Most of the specimens are 

 covered more or less thoroughly with a dense indurated mass of 

 argillaceous material, which from its appearance is undoubtedly the 

 all-pervading adobe mud, so characteristic of the southwest. Its 

 habits are therefore somewhat different from those of the majority 

 of species, which seem to prefer clean loose sand. 



Elongatulus cannot readily be confounded with any other species 

 here described. 



V. crassilS Lee. — Blapstinus eras. : Ann. Lye. N. Y., V, p. 146. — Oblong- 

 oval, moderately convex, dark brown to piceous, feebly shining ; pubescence 

 short, robust and dense, conspicuous. Head moderately transverse, densely 

 punctate ; epistoma broadly, deeply sinuate ; upper lobe of eyes rather small ; 

 antennae slender toward base, very moderately robust toward the apex, third 

 joint slender but shorter than the next two, tenth scarcely more than one- 

 third wider than long, eleventh fully as wide as the tenth, as long as wide, 

 narrowly truncate. Prothorax a little more than twice as wide as long ; apex 

 broadly, moderately emarginate in circular arc ; base broadly, feebly lobed 

 and more produced in the middle than at the basal angles, broadly, very feebly 

 sinuate laterally ; sides rather strongly arcuate anteriorly, nearly parallel in 

 basal two-thirds ; disk rather finely and very densely punctate throughout, 

 the punctures generally distinctly crowded and in mutual contact. Scutellum 

 polished. Elijtra just visibly wider than the prothorax and not more than 

 three times as long ; apex rather acute ; disk with moderate, rather distinctly 

 impressed striae, which are not very coarsely but very closely punctate ; 

 intervals alternately narrower and fiat, and wider and feebly but distinctly
