Coleopterological Notices, V. 343 



T. pilosa n. sp. — Suboval, convex, polished, black throughout ; legs and 

 antennae toward base pale ; integuments finely, rather strongly reticulate 

 throughout ; head and pronotum subimpunctate ; elytra finely, very feebly, 

 rather closely so, the abdomen finely, very sparsely and granularly ; pubes- 

 cence even in length, long, erect, moderately dense, conspicuous. Head nearly 

 as long as wide, small, not more than two- thirds as wide as the prothorax ; 

 eyes prominent ; tempora longer than the eye, feebly convergent and straight 

 behind them, rounded at base : surface broadly, strongly impressed in the 

 middle ; antennse stout, bristling, but slightly longer than the head and pro- 

 thorax, the first joint distinctly longer than the second, the latter much longer 

 than the third, which is scarcely at all longer than wide, constricted at base, 

 fourth a little wider than long, four to six difl"ering but little, seven to ten 

 larger, more pubescent, increasing more rapidly in width, tenth about twice 

 as wide as long, eleventh scarcely as long as the two preceding. Prothorax 

 fully two-thirds wider than long, sides strongly cojivergent and arcuate from 

 base to apex ; base very much wider than the apex, both strongly arcuate ; 

 basal angles very obtuse but distinct ; disk strongly convex, with three ex- 

 tremely obsolete parallel median longitudinal impressions, and a very obsolete 

 transverse impression before the base. Elytra wider than long, one-third 

 wider and nearly one-half longer than the prothorax ; sides perceptibly 

 divergent from the base and broadly arcuate ; disk impressed behind the 

 scutellum. Abdomen in the middle as wide as the elytra, at base very slightly 

 narrower, as long as the anterior parts. Length 1.4 mm. ; width 0.5 mm. 



Rhode Island (Boston Neck). 



A very interesting species, wholly different from the preceding 

 in the form of the prothorax, and from robustula in its narrower 

 form, erect hirsute vestiture and other structural characters. Two 

 specimens. The impressions of the pronotum are extremely feeble, 

 and join the transverse subbasal impression ; in one of the specimens 

 the longitudinal impressions are obsolete, and at best they can be 

 only faintly seen. 



T. rol>llstllla n. sp. — Rather stout and convex, suboval, black, the legs 

 and antennse toward base pale ; integuments densely and strongly reticulate 

 and alutaceous, the head and abdomen less strongly so and shining ; head 

 subimpunctate ; pronotum very minutely and feebly so, the elytra more 

 strongly densely and subasperately but still very finely, the abdomen sparsely, 

 extremely finely and subasperately ; pubescence rather long, decumbent, con- 

 spicuous, ashy in color, very sparse on the head and abdomen. Head rather 

 small, convex, impressed in the centre, scarcely three-fourths as wide as the 

 prothorax, wider than long ; eyes at somewhat more than their own length 

 from the base, not very prominent, the tempora perfectly parallel and straight 

 behind them, then broadly rounded to the base ; antennse attaining basal 

 third of the elytra, the basal joint longer than the second, the latter as long 

 as the next two, fourth slightly wider than long, outer joints gradually
