C. incerta sp. nov. — Oblong-elongate, rufotestaceons or brown; pubescence 

 moderately long, grayish, recumbent. Head evenly, rather strongly, bu1 not 

 closely punctate : eyes moderate, tempora nearly one-third as long as the eye. 

 Antenna- moderate, joints !i and 10 slightly transverse. Prothorax feebly cor- 

 date, widest but little before, the middle, the base but little narrower than the 

 apex; side margin crennlato-denticulate; surface rather closely punctate, the 

 punctures coarser, subrugose and close, at the sides, but finer and separated by 

 their own diameters at the middle; basal fovea round, moderately impressed. 

 Elytra subparallel, sides broadly rounded : stria- very faintly impressed, the 

 punctures rather coarse toward the base; interspaces more finely punctate. 

 Sterna moderately closely, strongly punctate; abdomen finely, sparsely punctate, 

 more distinctly on the first segment. Metasternum longer than the first ventral ; 

 middle coxae distant but little less than half the coxal width. Legs moderate. 



Male. — Front and middle tibiae feebly sinuate and mucronate internally at the 

 apex; fifth ventral scarcely visibly impressed. 



Female. — Tibiae simple; fifth ventral not at all impressed. 



Length 2.1-2,3 mm. 



ILib. — New Hampshire (Mt. Vernon — Blanchard); Lake Supe- 

 rior (Isle Royal — Hubbard and Schwarz). 



A female from the former and a male from the latter locality are 

 before me. Resemble* serrieollis most closely, but the non-foveate 

 fifth ventral of the female at once separates it; the punctuation is 

 also rather coarser and closer, and the prothorax is less narrowed 

 behind. From serrata, which also bears a general likeness, it is dis- 

 tinguishable by its generally larger size, less close punctuation, 

 much longer tempora and the scarcely evident impression of the 

 fifth ventral in the male, which is here discal and in serrata apical. 



C apicalis sp. nov. — Oblong, subovate, convex, rufotestaceons, apical half 

 of elytra piceous; pubescence pale, recumbent. Head rattier densely, strongly 

 punctate; eyes moderately prominent; tempora nearly one-third as long as the 

 eyes, diverging posteriorly. Antennae moderate, ninth joint about as long as 

 wide, tenth a little transverse. Prothorax transverse, feebly cordate, widest 

 slightly in advance of the middle, base a little narrower than the apex, side 

 margins crenulato-denticulate ; surface closely, moderately coarsely punctate 

 throughout, the punctures a little less close at the middle, but everywhere less 

 distant than their own diameters; basal fovea round and moderately deep. 

 Elytra elongate-ovate, punctures rather coarse, those of the interspaces a little 

 finer. Beneath moderately closely and coarsely punctate anteriorly, the punc- 

 tures of the metasternum finer and sparser at the middle: first ventral sparsely 

 but distinctly punctate, following segments more finely but not more sparsely 

 punctate; surface of abdomen shining and polished at base, duller and finely alu- 

 taceous toward the apex. Metasternum longer than the first ventral segment; 

 middle coxa? separated by one-half the coxal width. Legs moderate. 



Male. — Unknown. 



Female. Tibia' simple ; fifth ventral plane. 



Length 2 mm.
