104 SUBFAMILV X. CURCULIONINJE. 



214 ( ). LisTuoxoxrs DEBILIS sp. nov. 



Oblong, rather robust. Black, above and under surface, except abdo- 

 men, densely clothed with a crust of small, round, dirty white scales, 

 each with a minute golden dot at center; antennae, tibiae and tarsi reddish- 

 brown ; femora piceous, densely scaly near apex. Beak slender, sub- 

 cylindrical, as long as head and thorax, naked, feebly carinate and slightly 

 widened on apical third, not carinate and densely scaly behind the anten- 

 nae; frontal fovea large, deep. Thorax slightly wider than long, sides 

 broadly rounded, feebly but distinctly sinuate at middle, disc densely and 

 finely granulate-punctate. Elytra at base one-third wider than middle of 

 thorax, humeri rounded, sides parallel to apical fourth, then converging to 

 the conjointly rounded apex; stria? very fine, their punctures concealed; 

 intervals wide, flat, each with a row of short, white inclined bristles. 

 Length 5.5 mm. (W. 8. B.) 



Putnam and Vig'o counties, Ind., rare; June 12 July 1. A 

 unique form, easily known by the peculiar color of scales, sinuate 

 thorax and scaly head. The last yentral is not impressed in either 

 of the two specimens, both of which are probably males. 



IV. HYPERODES Jekel,* 1804. ((Jr., Hypera + "like.") 



Small oblong- or elongate-oval species haying the eyes lateral, 

 not encroaching 1 on the front; beak deflexed, narrower than head, 

 slighlly widened at tip and with one or more carina? on its upper 

 face; antenna? inserted near tip of beak, their grooves deep in 

 front and visible from above, directed against the eyes, usually 

 shallow and more or less widened behind; scape clavate, reaching 

 the eye, first joint of funicle always stouter than second, the two 

 usually sub-equal in length, 3 6 of almost equal width, seventh 

 wider; thorax never longer than wide, ocular lobes distinct; 

 scutellum small ; elytra oblong-oval, wider than thorax, usually 

 emarginate at base, slightly narrowed toward apex; femora cla- 

 vate. Males with the third joint of tarsi moderately dilated, and 

 the last ventral subtruucate; females with the last ventral broadly 

 rounded, usually more or less impressed. 



Like the species of Listronotiifi, they occur beneath cover on 

 sandy or muddy ground near water, or upon semi-aquatic plants. 

 They probably feed upon such plants, though the life history of 

 no species is recorded. Up to the present they may, therefore, be 

 termed innocuous rather than injurious to agriculture. The only 

 paper treating of the North American species as a whole is by 



J)h /.:, Win. G. "On the Species of Macrops Inhabiting North 

 America," in Trans. Am. Ent. Soc.. XVI, 1889, 2854. 



In it 33 species are described from the United States. Of 

 these 18 occur in the territory covered by this paper, while four 



*This name takes the place of Macrops Kirby which was preoccupied in Reptilia.
