Tibiae not serrate on tlie inner side ANCHODEMUS. 



Front and middle tibite serrate LIXELLUS. 



ANCHODEMUS n. g. 



I have establislied tliis genus upon tliree narrow species resembling in 

 form the European Bagous (Lt/prus) cylindrus, but quite ditlercnt by the 

 prosternum not being excavated, and by the tarsi broad and hairy, the tir&t 

 and second joints as wide as long, third wider, deeply bilobed ; fourth as 

 long as the two preceding united, claws large, divergent ; antennae inserted 

 about one-fourth from the end of the beak, scape reaching the eyes ; funic- 

 ulus 7-jointed; first joint stouter, second equal in length to the first, 3-7 

 short and gradually broader ; club elongate, annulated. Beak as long as 

 the prothorax, not very slender, cylindrical ; antennal grooves commen- 

 cing one-third from the tip, scarcely attaining the eyes, wiiich are large, 

 transverse, and rather coarsely granulated. Prosternum broad, somewhat 

 flattened, emarginate in front, not sulcate; postocular lobes distinct, coxsb 

 large, prominent, with a deep transverse impression in front of the coxa;. 



Scales brownish-gray, not mottled 1. angustus. 



grayish-white, " " 2. Hubbardi 



" brown, cl^ytra with a paler Inind 3. Schwarzi. 



1 A. angustus, n. sp. 



Elongate, blackish-brown, covered with a dirt-colored crust; beak slender, 

 tip naked and shining ; prothorax longer than wide, sides parallel, a little 

 narrowed and rounded near the tip, which is constricted, base oblique each 

 side, obtusely angulated at the middle. Elytra about one fourth wider than 

 the prothorax and tliree times as long, humeri oblique, angulated; stri* 

 punctured, interspaces nearly flat, each with a row of very small ])ristles. 

 Tibiie slender, slightly bent ; apical hook small ; antenna; and legs testa- 

 ceous ; second joint of funicle but little longer than first. Length 4 mm. ; 

 .15 inch. 



Michigan, Hubbard and Schwarz ; Illinois, Walsh ; New York, Ulke. 

 Greatly resembles in appearance Hydronomus' alismatis of Europe. 



2. A. Hubbardi, n. sp. 



Elongate, black, covered with a dense crust of grayish-white scales. 

 Beak, antennre, and legs, yellow-brown. Beak as long as the prothorax, 

 nearly straight, naked, shining, finely punctulate and slightly puliescent at 

 the base, whei'e it is finely carinate and feebly bisulcate ; frontal fovea dis- 

 tinct. Prothorax not longer than wide, slightly rounded on the sides, dis- 

 tinctly constricted near the tip. Elytra about one fourth wider than the 

 prothorax, humeri rounded, sides parallel, then obliquely narrowed, tips 

 separately acuminate and rounded, and Siightly thickened ; strife obscured 

 by the scales, shallow and punctured. Antennae with the second joint of 

 the funicle twice as long as the first. Tarsi with the third joint bilobed, 

 scarcely wider than the second. Length 7.5 mm. ; .30 inch. 



Detroit, Michigan ; Messrs. Hubbard & Schwarz, A fine species, of large 

 size for the tribe to which it belongs.
