in a grocery store until December. Motschulsky (18.~>r>, 77) re- 

 cords the importation of this species at the exposition in New 

 York in 1853 with the agricultural products from Cayenne, the 

 insects flying about as one approached the exhibits and continu- 

 ing to develop during the summer months. 



The beetle is very active, running, leaping and flying readily 

 when disturbed, and is always liable to occur in seaports, but 

 does not become acclimatized north of the cotton belt, though it 

 feeds on a variety of plants. It closely resembles Brachytarsus 

 alteriHitus Say in form, size and markings, but is easily separated 

 by the position of the anteunal fovese. 



XVII. CHORAGUS* Kirby, 1818. (A mythological name.) 



Small brownish or blackish species resembling dwarf forms 

 of Cryptocephalus and having the beak short, flat, deflexed, di- 

 lated and subtruncate at tip ; antennae inserted on its upper basal 

 surface, joints 1 and 2 robust, conical, subequal, 6 8 slender, 

 elongate, 1) 11 ovate-oblong; thorax convex, wider than long, 

 much narrowed in front, the base subsiuuate; scutellum minute; 

 elytra as wide at base as thorax, subcylindrical ; femora clavate, 

 tibiae almost straight, tarsi elongate. Four species occur in the 

 United States.

Elongate-oval, subcylindrical. Dark brown, the elytra paler, slightly 

 pubescent; antennae reddish-brown; tarsi piceous. Thorax minutely and 

 densely punctured. Elytra deeply striate-punctate, shining; intervals less

 bia, not rare on dead twigs. Ohio, in twigs of dead beech in- 

 fested with fungus. Larger and narrower than the next with 

 darker legs and shining elytra. 



*Jordan (Biologia, p. 382) has erected a new genus, liolostilpna, with Choragus jiitcus 

 Lee. as type. Until he treats the Anthribidae of the world in Genera Instclorum we 

 deem it premature to alter our nomenclature.
