doubt, which will prevent us from placing the genus among the 

 allies of Colpodota. 



A. flisiforitlis n. sp. — Rather stout, black, the elytra just visibly rufo- 

 piceous ; legs and antennae throughout pale ; integuments finely but not 

 strongly reticulate, rather shining, the head very sparsely, obsoletely punc- 

 tate, more coarsely so toward the sides and base ; pronotum finely, not densely 

 and obsoletely, the elytra strongly, closelj and asperately punctate, the abdo- 

 men more sparsely, feebly and subasperately, very sparsely so toward apex ; 

 pubescence short, coarse, decumbent, moderately distinct, sparser on the abdo- 

 men, the latter bristling with long erect setae toward apex. Head orbicular, 

 wider tlian long, about three-fifths as wide as the prothorax, strongly, evenly 

 convex ; eyes not prominent, at rather less than their own length from the 

 base ; antennae long, slender, fully attaining the middle of the elytra, the 

 fourth and fifth joints longer than wide, about two-thirds as long as the third, 

 outer joints rather loosely connected, very feebly increasing in width, the tenth 

 not distinctly wider than long, eleventh pointed, as long as the two preceding. 

 Prothorax three-fourths wider than long; sides broadly arcuate, subparallel 

 toward base, becoming straighter and distinctly convergent in apical half; 

 base broadly, strongly arcuate, much wider than the truncate apex, becom- 

 ing feebly subsinuate near the basal angles, which are obtuse and slightly 

 rounded ; apical angles only feebly deflexed, rounded ; disk transversely, 

 strongly convex, very obsoletely impressed along the median line toward the 

 middle, the posterior margin strongly beaded- Eltfira two-fifths wider than 

 long, at base scarcely as wide as the pronotal disk, but at apex distinctly 

 wider, about one-third longer ; sides distinctly divergent, subarcuate ; humeri 

 concealed ; disk rather strongly, indefinitely impressed on the suture behind 

 the scutellum. Abdomen equal in length to the anterior parts, at base slightly 

 narrower than the elytra, the apex of the fifth segment scarcely more than 

 one-half as wide as the elytral apex ; tergites, except the first, perfectly even, 

 not impressed, broadly, feebly convex toward the abdominal apex. Length 

 2.1 mm.; width 0.75 ram. 



N'ew York (near the city). Mr. H. H. Smith. 



The single specimen in my cabinet has no sexual marks of promi- 

 nence; the sixth tergite is feebly exserted, much narrower than the 

 fifth, with its apex feebly, evenly sinuato-truncate. 



THIASOPHILA Kraatz. 



The American species of this genus resemble the European 

 angulala Er., in all essential points of structure, sculpture and 

 vestiture, but have the prothorax a trifle wider near the base, and 

 the abdomen more parallel and much more distinctly narrower than 

 the elytra. The genus is widely diffused throughout the subarctic
