NORTH AMERICAN COLEOPTERA. 87 



larged, cylindrical and sub-equal ; all the joints are coarsely pubescent. Abdominal 

 segments nearly equal. Length 1.9 — 2.4 mm. 



D. C, Mich. Plate VI, Fig. G. 

 Does not appear to be very common. 



9. li. adustns Lee— Form convex. Surface of head and prothorax thickly 

 and very coarsely punctured, glabrous; elytra punctato -striate. Body, legs and 

 antennae very dark ferruginous. Head sub-triangular; eyes rather large, very 

 convex and prominent; transverse groove not prominent. Prothorax equal in 

 width to breadth across the eyes, very short and convex ; sides very arcuate ante- 

 riorly, and converging posteriorly ; anterior angles evenly rounded ; posterior an- 

 gles prominent and projecting; lateral grooves very well marked. Elytra equal 

 in length to twice the head and prothorax together, convex and evenly rounded 

 behind, entire ; sides slightly arcuate ; surface covered sparsely with rather short 

 setae arranged in rows. Abdominal segments sub-equal. Antennae but slightly 

 longer than head and prothorax together ; last three joints suddenly longer, and 

 last joint broadest, strongly flattened and broadly carinated; all coarsely pubes- 

 cent. The female antennae are rather shorter, and the last joint normally conical. 

 The epistoma also seems to be a little more acutely emarginated in the female. 

 Scutellum transverse, sub-triangular. Length 1.4 — 2.0 mm. 



Plate VI, Fig. 7. 



A very common, widely diffused species. The elytra are usually 

 clouded posteriorly with a darker castaneous tint. 



10. Ij, testaceus (Fab.) — Form moderately elongated, depressed. Head and 

 prothorax rather finely punctured ; punctures of head slightly more scattered ; 

 elytra foveo-striolate; body, legs and antennae testaceous; integuments dense. 

 Head sub-triangular; eyes moderate, convex and slightly in advance of posterior 

 angles; transverse groove and median line very evident. Prothorax quadrate, 

 covered with short and sparse setae ; sides converging behind, slightlj' in % , almost 

 parallel in 9> anterior angles very plainly toothed ; posterior angles right; lateral 

 striae strongly developed. Elytra elongated ; as wide as, or wider than prothorax ; 

 one-half as long again as the head and prothorax together, covering entire abdo- 

 men with the exception of the tip of the fifth ventral segment; rather obtusely 

 truncated behind, and covered with very short and sparse setae arranged in rows; 

 second, third and fourth abdominal segments equal ; first and fifth sub-equal, and 

 each about half as long again as the second ; all sparsely pubescent. Antennae % 

 nearly equal in length to entire body, last seven joints equal and cylindrical, first 

 joint nearly equal to the next two in length, and much the most robust of any ; 

 second and third joints equal in length. Antennae 9 e^iual in length to elytra ; 

 first joint largest, last three longer than the preceding, and very slightly broader. 

 Scutellum sub-triangular. Length I. .3— 1.9 mm. 



Plate VI, Fig. 8, ? . 



This is a common cosmopolitan species. 



11. I^. niteiis Lee. — Form elongated, depressed. Head and prothorax testa- 

 ceous ; elytra paler, thinner and translucent ; legs and antennae testaceous ; surface 

 shining; punctuation of head and prothorax very sparse and fine. Head sub- 

 triangular; eyes moderate, situated very near the posterior angles; transverse 

 groove well developed; median line not distinct. Prothorax sub-quadrate, as wide
