Front and middle tibiaj serrate LIXELLUS. 



ANCHODEMUS n. g. 



I have established this genns upon three narrow species resembling in 

 form the European Bagous {Lyprus) cylindrus, but quite different by the 

 presternum not being excavated, and by the tarsi broad and hairy, the first 

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

 long as the two preceding united, claws large, divergent ; antennaj 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-tliird from the tip, scarcely attaining the eyes, which are large, 

 transverse, and rather coarsely granulated. Prosternum broad, somewhat 

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

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



Scales brownish-gray, not mottled 1. angustus. 



grayish-white, " " 2. Hubbardi 



" brown, elytra with a paler band 3. Schwarzi. 



1 A. angustus, n. sp. 



Elongate, blackish-brown, covered Avith 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 three times as long, humeri oblique, angulated; striae 

 punctured, interspaces nearly flat, each with a row of very small bristles. 

 Tibiae slender, slightly bent ; apical hook small ; antennse and legs testa- 

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

 .15 indi.

 Greatly i*esembles in appearance Ilydronomus alismatis of Europe. 



3. A. Hubbardi, u. sp. 



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

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

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

 the base, where it is finely cariuate 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 ; striae 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.
