1 86 MEMOIRS ON THE COLEOPTERA 



New York (Long Island), New Jersey and Virginia (Fortress Mon- 

 roe). Abundant. [Tachys xanthopits Lee. nee Dej.]. .levipes n. sp. 



Body stout, very convex, ventricose, black, polished, each elytron with 

 a large discal rufous spot near apical fourth; under surface piceous, 

 the hind body rufous, the legs flavo-rufous; head well developed, 

 much larger than in levipes, with rather large and prominent eyes, 

 two-thirds as wide as the prothorax, the anterior strides distinct, 

 parallel; antennae slender, but very feebly incrassate, fuscous, paler 

 at base, nearly three-fourths as long as the elytra; prothorax as in 

 levipes, but slightly shorter and more transverse and differing in 

 having the fine subbasal sulcus only visible toward the foveae and 

 finely punctate, the wide vacant median space with three strong 

 isolated punctures, of which the median is much the largest; elytra 

 very nearly one-half longer than wide, three-sevenths wider than the 

 prothorax, gradually parabolic in about apical two-fifths, broader 

 and with more arcuate sides than in levipes; sutural stria virtually 

 attaining the base, the second feebler and much abbreviated; out- 

 side of this there are feeble impressed traces of two or three other 

 striae as a rule; foveae strong, at two and four sevenths, adjoining 

 the third faint line, these lines not sufficiently distinct to associate 

 the species with vivax and allied species. Length 1.9-2.3 mm.; 

 width 0.72-0.9 mm. Texas (Galveston and Austin), Louisiana 

 (Alexandria), Mississippi (Vicksburg), Indiana and Iowa (Keokuk). 

 Abundant rubricauda n. sp. 



19 Form oblong, strongly convex, deep polished black, the elytra feebly 

 picescent; under surface black, the legs obscure testaceous; head 

 three-fifths as wide as the prothorax, with relatively large and prom- 

 inent eyes, the anterior strioles small but deep; antennae slender, 

 feebly incrasstilate, three-fourths as long as the elytra, fuscous, the 

 first three or four joints flavo-testaceous; prothorax large, fully two- 

 fifths wider than long, widest just before the middle, the sides broadly 

 and strongly rounded, straight -and oblique posteriorly; subbasal 

 sulcus impunctate, entire, the space between it and the basal margin 

 convex and bead-like; elytra barely two-fifths longer than wide and 

 about a third wider than the prothorax, parallel, with but slightly 

 arcuate sides and rapidly rounded humeri, arcuately ogival in about 

 apical third; sutural stria very slightly abbreviated at base, the 

 second rather finer, shorter and feebler than usual in this subsec- 

 tion; .foveae at two and four sevenths. Length 1.75 mm.; width 

 0.8 mm. North Carolina (Southern Pines), Manee. Six exam- 

 ples. Size rather uniform ancilla n. sp. 



Form nearly as in the preceding, but less stout, the prothorax not quite 

 so large, piceous-black, polished, the under surface rufous, the legs 

 more flavate; head larger and nearly two-thirds as wide as the pro- 

 thorax, with still larger and prominent eyes, the strioles and antennae 

 somewhat as in ancilla; prothorax nearly one-half wider than long, 

 in form and structure as in the preceding; base similarly distinctly 

 wider than the apex; subbasal sulcus impunctate, rather shallower 

 than in ancilla and, at the middle, having a single very faint sub- 

 punctiform impression; elytra as in ancilla but shorter, ogivally
