AMERICAN LEPIDOPTERA. 7 



per surface of secondaries in ornamentation. Basally and centrally 

 the wing is covered with bright rose-colored, longer, hair-like scales, 

 foruiiug a middle triangular patch. A large, distinct, deep black dis- 

 cal blotch, lying immediately beyond the cell. An external darker 

 transverse band, diffusely shaded outwardly, and becoming roseate 

 where it crosses the middle patch. Internal angle washed with lilac. 

 Elsewhere the ground color of the wing is as on upper surfixce, becom- 

 ing very pale along internal margin. 



Secondaries, above, with a centi'al bright xose-colored patch of 

 longer, hair-like scales. A large, distinct, deep black, discal blotch 

 like that on under surfoce of primaries. An arcuate, external, trans- 

 verse line, becoming roseate where it crosses the central bright shade, 

 above and below which it is more faintly continued. Elsewhere the 

 secondaries are concolorous with upper surface of primaries, and are 

 slightly touched with lilac over anal angle. Under surface, pale dull 

 brownish ochreous, obsoletely irrorate, without markings, except a me- 

 dian diffuse darker shade band which is broadest on costa and discon- 

 tinued inferiorly. 



Expanse^ 3.00 inches. Length of hoihj^ 1.25 inch. 



Habitat. — Mexico, (W. H. Edwards, Esq.) 



This species is very distinct from Adelocephala subangulata, as illus- 

 trated by Dr. Herrich-Schaeffer. Our specimen has lost some of the 

 scales, at the base of the wings above, by atrition. 



ADELOCEPHALA. Boisd. 

 Mr. Walker, (C. B. M., Lep. Het. PI. 6, p. 1498), in writing for 

 the first time upon this genus, ascribes simple antennae Q'Foevi. — 

 Anteniife simplices.") to the female. But the first species cited — 

 Adelocephala cadnius, Boisd — as illustrated by Dr. Herrich-Schaeffer, 

 has the antennfe (fig. 78) feathered at base, and but little less promi- 

 nently than in the male (fig. 77), from which latter it differs in the 

 rounded external margins of the wings. We describe here a new 

 Mexican species of the genus, which approaches our United States A. 

 bicolor, Harris, sp., quite closely in habitus and structure, but the 

 antennae (9) are simple. In the shape of the secondaries, the pecu- 

 liar color and structure of the feet, our new species (A. quadrilineata), 

 agrees with, and otherwise presents no marked differences when com- 

 pared with A. bicolor. In the female Adelocephala anthonilis, Boisd., 

 the antennae are basally impectinate, and in a large and heavy, hith- 

 erto undescribed Mexican species, (A. grandis, nob.) which equals in 

 size the Brazillian A. cadmus, the 9 antennae are also simple. This
