AdDALIA QUADRILINEATA, Sp. 710V. Plate 10, fig. 64. 



8 $ and 6 9. — Fore wings less acute and hind wings less angled than 

 in A. enucleata. Front black, extreme edge paler. Palpi rather large, heavier 

 than usual, projecting well beyond the front, and blackish above. Antennae 

 of male whitish above, beneath testaceous, with a minute fringe. Wings 

 white, peppered over with black scales, with sometimes five (usually three) 

 rather broad, pale-ochreous, oblique, firm lines, the marginal one curved and 

 parallel with the edge of the wing; costal border ochreous; fringe long, 

 ochreous at base. The same arrangement of four lines on the hind wings, 

 the lines being very equal in size, three of them being a little broader and 

 more diffuse than the basal one. Beneath, the wing is subochreous on the 

 costal and outer edge, usually with a dark scalloped line common to both 

 wings, and situated half-way between the discal dot and outer edge. Legs 

 white, fore legs brownish. Hind tibiae flattened and swollen, but less so than 

 in A. enucleata, while the tarsi are two-thirds as long as the % tibia\ 



Length of body, 3, 0.38, 9, 0.35; of fore wing, <?, 50, 9, 0.50; 

 expanse of wings, 1.08 inches.

This moth, where it occurs, is fully as common as A. enucleata, but 

 seems more restricted to the Northern States. It differs from A. enucleata, 

 to which it is nearest allied, by its smaller size, the much longer hind tarsi 

 and shorter tibia?, the less pointed and angulated wings, by the want of any 

 discal dot and marginal black dots, while the extradiscal line is firm, not 

 waved. It varies much in the. number of the lines, there being often only 

 three lines on the fore wings and three on the hind wings, and sometimes 

 the lines are nearly effaced. It differs from AValker's description of A. restric- 

 tata in wanting any discal dots or submarginal lines, and in its smaller size. 

 On a comparison with Mr. Walker's type of A. restrictata, kindly made for me 

 by Mr. Charles O. Waterhouse, assistant in the British Museum, it proves to 

 be different. Mr. Waterhouse writes me that it "differs from the specimens 

 [of A. quadrilineata] sent, in having the apical of the three transverse bands
