1834 BUTTERFLIES BEYOND NEW ENGLAND. 



cell beyond the middle at right angles to the costal margin ; extending above half way 

 between the cell and the margin, below abont to the centre of the medio-submedian 

 interspace, its exterior margin crossing the cell above about midway between the base 

 of the first and of the second subcostal nervules and below just including the extreme 

 base of the upper median interspace, the whole rather broader than the cell and 

 rounded beneath; the apical half of the costal and the upper half of the outer margin 

 marked in black, most distinctly at the middle of the interspaces, those on the lower 

 half of the wing being marked apically in the same way ; besides there is a very broad 

 exterior mealy band of raised scales, in the form of broad and very longlunulesiu the 

 interspaces, separated apically only by the nervures, and extending to the depth of an 

 interspace and a half in the lower half of the wing, as far as the cell above, even filling 

 the whole of the upper subcostal interspaces and often present as a small patch in the 

 apex of the cell itself (^) ; or, sordid yellow often more or less pallid, sometimes with 

 an orange tinge especially toward the outer border, with the marginal markings of the 

 other sex to form distinct, tolerably large, transverse, oval, blackish brown spots, con- 

 fluent with a narrow band at the apex of the wing, besides having an extra-mesial 

 series of smaller and more or less powdery spots in all the subcostal and median inter- 

 spaces, near the middle of the apical two-thirds of each interspace, forming thus a 

 tolerably sinnous series, bent strongly at about right angles at the apex by the spots in 

 the upper subcostal interspaces ; besides these an obscure similar spot at the lower 

 extremity of the cell cut by the transverse nervure ( ? ). Hind wings of the same coloras 

 the fore wings, the outer margin with a very broad suffused blush of yellow orange ( <? ) 

 or red orange (?) growing deeper in tone toward the outer margin, much broader 

 (often covering half the wing) in the female than in the male and in both narrowing 

 and fading above and below ; it is accompanied in the female by tolerably large, trans- 

 verse, oval, powdery, blackish spots barely before the margin seated on the nervules 

 instead of, as on the fore wings, in the interspaces. In the male there is a very nar- 

 row, uniform area of raised scales along the outer margin. 



Beneath orange buff, heavily flecked in the female with ferruginous orange. Fore 

 winys with the dark markings of the upper surface of the female repeated in both 

 sexes in ferruginous with these variations : the marginal markings of the male are 

 even less distinct than in the same sex above, often quite absent; and the spot at the 

 end of the cell is generally larger, accompanied by another seated on the upper trans- 

 verse vein and both more or less heavily pupiled with silvery. Hind wings crossed, 

 more heavily in the female than in the male, by an extra-mesial series of very powdery 

 ferruginous, slender lunules corresponding to the similar series of the fore wings, 

 besides similar, transverse, powdery, ferruginous bars forming a "subcontinuous, nar- 

 row, bent, V-shaped stripe near the base of the wing below the subcostal nervure, ac- 

 companied by a bar edging interiorly the lower, outer margin of the cell and two small 

 silvery ovals on either side of the extreme base of the last subcostal nervule, set at 

 right angles to each other (more distinctly in male than female) and edged with ferru- 

 ginous. Expanse of wings, 80-98 mm. 



This Callidryas, like the preceding, is a tropical species, extending from 

 Mexico to Bahia, but is ai)parently confined to the mainland and so invades 

 the United States only at one point, so that, so far as known, it is only 

 found constantly in Texas, but it, too, occasionally flies northward up the 

 Mississippi valley and has been found even as far as northern Illinois 

 (Evanston, Bontell) and Wisconsin (Racine, Hoy). 



The early stages are quite unknown and no information is at hand re- 

 garding the history or seasons of the insect.
