NORTH AMERICAN COLEOPTERA. 



205 



deeply striate, the strife punctured, intervals tlat, biseriately punetulate. Proster- 

 num smooth posteriorly, coarsely sparsely punctate in front, strise deep, parallel, 

 but not entire. Metasternum and abdomen coarsely but not closely punctate. 

 Length .10 inch; 2.r> mm. 



This species is usually mixed in cabinets with niendax. It is, how- 

 ever, more finely and sparsely pubescent, the frontal carinse more distinct 

 and with abbreviated prosternal strit^j. 



Occurs in California, and widely diffused. 



T. (lebilis n. sp. — Form oblong, scarcely narrowed behind, castaneous or 

 ferruginous feebly shining, pubescence not dense, rather fine. Head indistinctly 

 punctate, front obtusely biearinate, the carinse parallel and distant. Thorax about 

 one and a half times as wide as long, gradually arcuately narrowed to the front, 

 hind angles very little prolonged, not carinate; disc moderately convex, basal re- 

 gion not depressed, surface with intermixed moderately close punctuation. Elytra 

 finely striate, the strise finely jjunctate, intervals flat, the second and fourth irregu- 

 larly biseriately punetulate, the others with a single series of punctures. Pros- 

 ternal striae extending very little in front of middle, the prosternum with verj' 

 ievf and very fine punctures. Metasternum and abdomen obsoletely, very sparsely 

 punctate. Length .08 inch ; 2 mm. 



In this species the prosternal striae are so much abbreviated that there 

 is no difiiculty in distinguishing it from any of those with obliquely 

 divided eyes. 



Occurs in Oregon and Washington Territory. 



I'ACTOPIIS Lee. 



Antenna? fusiform, a little longer than the head and thorax, received 

 in deep sinuous grooves in the sutures of the prosternum and which ex- 

 tend outwardly to the hind angles of the 

 prothorax, the tip of the antennae rest- 

 ing against the elytral humeri ; first 

 joint obconical, nearly twice as long as 

 the second which is slightly transverse ; 

 joints o— 7 nearly square, closely articu- 

 lated, 8-10 very little larger, eleventh 

 one-half longer, acute at tip. Eyes en- 

 tire. 



Tarsi long and slender, the joints 

 .simple, the first as long as the next 

 three ; middle and posterior tarsi received in grooves, those for the mid- 

 dle pair are on the metasternum and divergent, reaching the hind coxa? ; 

 those for the hind pair extend from the base of the first ventral segment 

 to the posterior margin of the third and are also divergent.
