7 — C. reductum n. sp.— Slender, black; elytra piceous, paler and distinctly 

 rufous at the apices; femora rather pale castaneons-brown, tibiae and tarsi 

 paler, brownish-flavate; under surface dark castaneous, tip of the abdomen 

 slightly TDaler; antennae dark rufo-testaceous; pubescence of the elytra very 

 short, fine and rather sparse, that of the abdomen much longer, coarser and 

 twice as dense; head and prouotum almost glabrous. Head robust, scarcely 

 longer than wide; sides parallel and nearly straight; base truncate, angles 

 rather broadly rounded; surface rather finely and sparsely punctate, espec- 

 ially toward the middle, where there is a rather broad impunctate line; an- 

 tennae distinctly shorter than the head and prothorax together, somewhat 

 robust; basal joint as long as the nest two together, second very slightly 

 shorter than the third, joints two and four equal in length, fifth slightly 

 shorter. Prothorax quadrate, just visibly wider than the head; sides feebly 

 convergent toward base and very feebly arcuate; base and apex broadly, 

 equally and not strongly arcuate; apical angles rather narrowly rounded, 

 basal very broadly so; disk transversely and rather feebly convex, finely, 

 densely and evenly punctate; punctures rounded, feebly impressed and dis- 

 tant by about their own widths; median line almost entire, very narrow. 

 Elytra at base very slightly wdder than the pronotum; sides nearly parallel 

 and feebly arcuate, more strongly so behind; together broadly, evenly and 

 very feebly sinuate at apex; disk one-fourth longer than wide and one-third 

 longer than the prothorax, narrowly impressed along the feebly elevated 

 suture, except toward tip, where the impression is obsolete, finely, rather 

 densely and sub-asperately punctate; punctures scarcely perceptibly smaller 

 toward the apex. Abdomen distinctly narrower at base than at the fourth 

 segment, slightly narrower than the elytra; sides feebly arcuate; sides of the 

 fifth segment distinctly convergent toward tip; surface transversely and 

 finely strigate in very disconnected wavy lines. Lefjs slender; first joint of 

 the posterior tarsi about as long as the next two together, second as long as 

 the fifth. Length 3.0 mm.

This species is distinguished from contradum by its 

 smaller size, shorter and broader head, which is also more 

 sparsely punctate, and by the form of the prothorax, in 

 which the sides are feebly but distinctly convergent from 

 apex to base. The type is a male, the sixth segment being 

 rather broad and sinuate at apex; the sinus is broadly 

 rounded and about four times as wide as deep. In co7i- 

 tractum the sinus is much more acutely rounded, although 

 about equally deep, the sides being more gradually recurved 

 exteriorly.
