TUIISK III. HYPERIXI. 1(>3 



211 (8455). LISTROXOTTS IMPRESSIFROXS LeConte, 1876, 134. 



Form and size of latiusfulus. Scales mostly dirty brown, the elytra not 

 mottled as there; thorax with a narrow pale stripe each side. Beak wider, 

 stouter, much more distinctly carinate and sulcate, sparsely covered with 

 large rounded scales intermingled with slender, hair-like ones. Frontal 

 fovea large, deep. Sides of thorax broadly rounded, disc densely and coarse- 

 ly punctured. Elytra mere than one-half broader at base than thorax, 

 intervals feebly convex. Last ventral of female not impressed. Length 

 5.5 5.8 mm. 



Described from Georgia and Louisiana. Quite common about 

 Lake Okeechobee., Fla., March 2 8, among and beneath the de- 

 caying stems of the water hyacinth, Piaropus crassipcs Mart., 

 next to the water's edge; also at Ihmedin, Jan. 1) March 31. 



212 (8454). LISTROXOTUS CRIURICOLLIS Lee., 1876, 134. 



Also of the form, color and sculpture of latiusculus. Thorax distinctly 

 wider than long, mere strongly rounded on sides, distinctly constricted 

 near tip, so that looking from above the postocular lobes appear more 

 prominent; humeral angles of elytra more distinctly oblique. Last 

 ventral of female with a large rounded impression, the bottom of which is 

 shining and nearly smooth. Length 6.7 mm. 



Such is LeCoute's description of his single female type from 

 Georgia. No other record can be found. 



213 (8456). LISTROXOTUS SETOSUS Lee., 1876, 134. 



Oblong. Black, above densely covered with round, dirty gray, fus- 

 cous-brown and silvery white scales, which are larger on the thorax 

 and not hair-like on the head; the fuscous ones forming a few irregular 

 blotches along the sides and a large one near the apex of elytra; the silvery 

 ones a narrow median line and a sinuous stripe each side of the thorax and 

 a few spots on sides of elytra; antennae, tibiae and tarsi reddish-brown; 

 femora blackish with a ring of silvery scales near apex. Beak rather 

 slender, longer than thorax, the median and lateral carina? evident but 

 weak. Thorax short, distinctly wider than long; sides rounded, strongly 

 so near base and apex; ocular lobes prominent, disc densely and coarsely 

 punctate. Elytra one-fourth wider at base than thorax, base broadly and 

 feebly emarginate; humeri rounded, striae rather finely punctate; inter- 

 vals feebly convex, each with a row of rather long, inclined, club-shaped 

 blackish bristles. Last ventral with a rounded shallow impression near 

 tip in male, and a very deep median cavity on apical half in female. Length 

 5 5.5 mm.
