$, . $ . — " Head, thorax and abdomen reddish ocherous. Anterior 

 wings dark ocherous yellow to reddish brown, with an oblique silvery 

 band, inclined towards the base of the wings, fi-om the costa to the 

 middle of the inner margin, and toothed toward the base on the sub- 

 median nervure or fold. A rather faint reddish-brown line extends 

 from the costal origin of the silvery band to the hind margin beneath 

 the middle. Hind wings pale ocherous yellow." 



" Var. (?). Imago brownish luteous, sometimes inclining to yel- 

 lowish. Fore wings with an oblique silvery band from the costa to 

 the middle of the inner margin, toothed on the submedian fold, and 

 shaded behind iviih blackish broivn, with a blackish brown line from the 

 costal origin of the silvery band to the hind margin beneath the middle. 

 Hind wings dark broivn, yellowish at the base." Clemens, (loc. cit.) 



Expanse of wings, 0.60 — 0.70 inch ; length of body, 0.30 inch. 



Habitat. — New York (Grote). Boston (Sanborn). Illinois, (Ken- 

 nicott, Clemens). Texas (Belfrage). 



Larva. — " Outline elliptical, somewhat pointed behind; body flat- 

 tened, with the sides curving from a central ridge, flattened above. 

 The ridge has a vertical elevation at its sides, growing less and less 

 before and behind, and terminates in front in a rounded margin, and 

 behind in an obtuse short spine. The body is smooth, with no dis- 

 tinct defined papulae, but the edges of the ridge and the oudine of the 

 body are thrown into folds, subcrenated. The body is thickest in the 

 middle, whence it curves anteriorly and posteriorly. General color of 

 the body is pale green and dotted with numerous yellow points. Cen- 

 tral ridge is bordered in front with yellow. " 



" The larva feeds on the underside of the leaf of maple in Septem- 

 ber, and the i7nag9 appears in the spring. There is doubtless a spring 

 brood of larvse." Clemens, (loc. cit.) 



The above description of the larva is given by the writer as belong- 

 \\-\<y to the type of his L. laticlavia, it being evident that he was unac- 

 quainted with the larva of the variety with blackish bands on the prima- 

 ries of the imago. The specimen here figured was received from Mr. 

 Belfrage, of Texas, along with others, all of which show the blackish 

 band on the primaries more or less distinctly, and in this respect cor- 

 respond more closely with the "var.'' of Dr. Clemens, than with his
