middle; the angle near the base at the flexure appears almost rectangular; 

 sides obliquely and broadly rounded. Elj^tra with striae of large punctures, 

 interspaces even, alternately variegated with distant, small white dots; a 

 spot of yellow and white hair covers the base of the 4-7 interspaces. Be- 

 neath thinly clothed with fine gray hair; legs mottled with gray hair; an- 

 tennte testaceous with dusky club, slender, extending to the base of the 

 prothorax. Length 4 mm. ; . 15 inch. 



Enterprise, Florida, two specimens; Mr. E. A. Schwarz. Quite different 

 in appearance from the preceding, though presenting no special structural 

 peculiarities. 



ALLANDRUS Lee. 



I have established this genus upon a small Canadian species remarkable 

 by the sexual differences The form is as slender as in Tropideres; the beak 

 is longer than the head, narrower at the base, slightly dilated at the tip; in 

 the male it is furnished with a very high crest, gradually fading out in 

 front; in the $ only an obsolete carina is seen. The antennae in the 9 ex- 

 tend to the base of the elytra, and are just as in Tropideres, except that the 

 second joint is thinner; joints 9-11 form an oval, compressed club. In the 

 (^ the antennae are as long as tlie body; joints 3-8 elongated, and a little 

 thickened at tip ; 9-11 flattened, forming a loose club. The prothorax as 

 in Tropideres, but not tuberculate at the sides; transverse ridge remote 

 from the base, feebly curved, and subsinuate; flexed obliquely forward at 

 the sides. Eyes rounded, lateral, prominent, finely granulated. Tarsi 

 more slender than usual; third joint not as wide as the second; claws 

 appendiculate rather than toothed. Mentum with the lobes wide, nar- 

 rowly rounded at tip; ligula large and coraceous, filling up the emargi- 

 na'ion of the mentum more than in the preceding genera, (somewhat as in 

 certain Lehiini). 



1. A. bifasciatus, n. sp. 



Blackish brown, with a brassy tinge; head and prothorax densely punc- 

 tured, thinly clothed with cinereous hair; the latter longer than wide, nar- 

 rowed at tip and base; elytra with punctured striae, and two ill-defined, 

 broad bands of cinereous hair; the anterior one extending along the suture 

 to the base; scutellum white. Length 4.3 mm. ; .17 inch.

Group III. Hormisci 



The genera upon which I have founded this group, seem sufiiciently 

 distinct from the other Corrhecerides of Lacordaire to be separated from 

 them. I would define it by the following characters: 



Beak not dilated at the sides over the antennal cavities. Eyes emargi- 

 nate, not finely granulated. Prothoracic ridge antebasal, curved or ob- 

 tusely angulate backwards at the middle, flexed obliquely forward at the 

 sides. Tarsi with the first joint long; second triangular, scarcely emarginate;
