"Closely resembles the male of .4. seiKiforic in color, but the hind wings are rounded as in 

 the female, not aiigulated at apex and anal ang-le, and the t.-jj. line is much more obscui-e. 



■'Female; wings purplish brown, basal iind terminal spaces darker; a white discal dot and 

 faint blackish strig-a^. Hind wings with a purplish mesial band. 



" Darker than either senatoria or sti(/?/ia, the lines less distinct; wing.s opaque, not thiidv 

 scaled as in i-irgini'e»sts. Types male and female, bi"ed from lar\ iv. 



This species also diifers from ^4. Ht'xjnm in the extradiscal line passing much nearer the 

 discal spot, and in being decidedly incurved. The white discal spot is smaller and the wings 

 more opaque. 



'"Zrt/vv/. — Primary spines black, secondary granules sparse, white. Head shining red- 

 l,)rown, width 3.5 to 4 mm. Body red-brown, a dorsal, subdorsal (i), latei'al (iii), stigmatal. and 

 subventral clouded black l)an(ls. Dorsal and stigmatal bands harp [dark ;] and narrow, the others 

 clouded, the subventral tilling the whole space. All except the subventral are bordered by white 

 shaded lines on the lower side, that below the stigmatal line very distinct. All the lines become 

 obsolete on joint \'l. leaving the anal end and all the feet red-brown. In large examples the 

 skin has a fleshy tint, different from the head and plates, while the shaded lines tend to be broken 

 at the primary' spines." — (Dyar). 



F'i'od plants. — Live oak. 



Habits. — Found by Doctor Dyar on the live oak in Januai-y in company with those of 

 A. stigma, etc. The larva of this species is I'epresented on PI. ^^ from a colored drawing made 

 by Mr. Joutel and kindly loaned me by Doctor Dyar. 



Geographical dixtriiivtinn. — West Palm Beach, Florida (Dyar).

Imago. — ^10 S , 40 $ . The characters of this species are best brought out by a comparative 

 description, as the females of this and ^4. stigma are scarcely distinguishable. 



The S differs from that of ^1. stigma in the hind wings being distinctly triangular, the apex 

 being less rounded, and the outer edge of the wing not so convex, while the inner angle is 

 slightly produced; the wings reach only two-thirds of the length of the abdomen: they do not 

 extend back so far as in ^I. xtigiiia. 



In one $ from Rhode Island the hue is fully as dark as in i A. stigma from southern Illinois, 

 and tlie discal spot is as large. The comnion extradiscal line is quite heavy, being on the hind
