[LeConte. 



3. A. Schwarzi, n. sp. 



Elongate, brown, densely clothed with brown scales ; pro thorax trivit- 

 tate with paler ; elytra clouded with pale, and with a broad conspicuous 

 common angulated band behind the middle, having the angle at the suture 

 directed forwards. Beak as long as the prothorax, stouter than in the other 

 two species, straight, densely punctured, slightly pubescent, not shining. 

 Prothorax a little longer than wide, very slightly rounded on the sides, not 

 constricted in front. Elytra more than one-third wider than the prothorax, 

 humeri oblique, slightly rounded ; striae fine, well impressed, finely punc- 

 tured ; tips conjointly rounded. Antennae and legs yellow-brown ; second 

 joint of funicle scarcely longer than the first ; third joint of tarsi broad, 

 bilobed. Length 4.5 mm. ; .175 inch. 



One specimen, Detroit, Michigan ; Messrs. Hubbard & Schwarz. Easily 

 recognized by the stouter beak, and conspicuous paler band of the elytra. 



LIXELLUS n. g. 



A small species of still narrower form constitutes this genus. It has pre- 

 cisely the appearance in miniature Of a slender Lixus, and differs from 

 AncJiodemus by the third joint of the tarsi being not wider than the second, 

 and not bilobed ; the fourth tarsal joint is as long as the others united, and 

 the claws are large and divergent. The thighs are less clavate, the tibiae 

 strongly bent, and the front and middle pairs are serrate on the inner edge 

 from the middle to the tip ; they are all feebly nmcronate at tip. The beak 

 is shorter than the prothorax, rather stout, nearly straight, and the anten- 

 nal grooves commence near the tip ; the funiculus is 6-jointed, with the 

 first and second joints longer, the joints 3-6 short, slightly wider, club 

 elongate oval, acute, annulated, pubescent. 



L. JJlifonfiis. n. sp. 



Very elongate, cylindrical, black, covered with extremely small brown 

 scales, mottled in color. Beak opaque, punctulate, and scaly. Prothorax 

 longer than wide, feebly constricted in front, sides nearly straight, very 

 densely punctulate. Elytra little wider than the prothorax, striae punc- 

 tured, interspaces flat ; tips conjointly rounded ; antennae and legs yellow- 

 brown. Length 4.3 mm. ; .17 inch. 



One specimen from Canada, and one from Oregon. 



Group VII. Hydronomi. 



The same varnish-like covering noticed in the three preceding groups is 

 retained in this, the species of which are also found on plants near water. 

 They are easily distinguished by the longer and more slender legs, the tibiae 

 curved, and frequently serrate on the inner side and strongly hooked at tip. 

 The tarsi are usually slender, the third joint frequently not dilated, and 

 the last joint moderate or very long, with stout, simple, divergent claws. 

 The prosternum is usually broadly sulcate.
