262 CURCULIONID^E. [LeCoiite. 



sides are slightly rounded near the base; the scales of the elytra are com- 

 paratively larger and denser, and there is no distinct pattern of paler spots. 

 Length 2.3 mm. ; .09 inch. 



Georgia, Illinois and Texas. The paler scales in well-preserved individ- 

 uals are condensed so as to give the appearance of three vittas on the pro- 

 thorax, and to leave two faint dark clouds on each elytron, one about the 

 middle, the other near the tip, separated by a sutural line and limited by 

 pale bands. 



3. C. mammilla/bus, n. sp. 



As large as the largest specimens of C. operculatus, but distinctly broader; 

 black, clothed with large oval scales of a light and dark brown color. Beak 

 densely punctured, subcarinate; front half as wide as the beak. Prothorax 

 not wider than long, sides feebly rounded, narrowed near the tip, and 

 rather strongly constricted; coarsely and densely punctured, with a large 

 subquadrate spot of white scales at the hind angles. Elytra slightly rounded 

 on the sides, suddenly sinuate near the tip, and then broadly rounded; the 

 tips are separately thickened and produced into a stout, conical, ascending- 

 process; the striae are punctured as usual, and the interspaces feebly con- 

 vex; the color is mottled, pale and dark brown and white. Beneath the 

 inetasternum and first and second ventral segments are covered with pale 

 scales, the rest darker; second ventral with two tubercles near the posterior 

 margin, about as distant from each other as from the side. Length 4.1 

 mm.; .16 inch. 



Southern California; one specimen collected by Mr. Hardy, and kindly 

 given me b} r Dr. David Sharp. The \vhite spots of the elytra are as fol- 

 lows : a small dot at the base of the sixth interspace; a transverse spot on 

 the second and third interspaces, one-fourth from the base; immediately 

 behind this spot is a large, dark space; a smaller transverse spot behind 

 the middle ; a large lateral spot opposite the first ventral segment, and an 

 adjoining small spot on the seventh interspace; the apical edge is also 

 clothed with whitish scales. 



4. O.^adspersugj n. sp. 



Elongate, black, beneath densely clothed with dirty white scales, above 

 with ochreous scales, varied with dark brown and white spots. Head and 

 front as in C. operculatus; antennae pale testaceous, second joint of funicle 

 longer than the third. Prothorax longer than wide, narrowed and feebly 

 constricted near the tip; surface coarsely and densel3 r punctured, scales 

 large, rounded, concealing the punctures, the white spots are three at the 

 base and three at the tip, indicating thus three, more or less interrupted 

 white vittse. Elytra with well marked punctured stria?, and flat inter- 

 spaces; white marks conspicuous, indicating an annular basal mark, com- 

 posed of small spots, then a long sutural line, and two oblique, interrupted 

 bands behind the middle. Hind thighs with an indistinct band. Length 

 3.3 mm.; .13 inch. 



Texas; four specimens. The scales are as large as in C. operculatus.
