faintly, in other dorsal rings. Anal tuft ample, black above and later- 

 ally at base; below deep reddisli orange. Claspers yellow. Legs: 

 eoxfe golden; other joints black outwardly, golden inwardly to claws; 

 last pair with middle of tibia and tips of basal joints ringed with golden ; 

 the inner side of foretibise are light orange; spurs concolorous with the 

 golden yellow legs. 



The female expands 20™™. General color the same as male, but dif- 

 fers in having less black at tips of palpi; in having much more golden 

 beneath the abdomen; in having the same extending over dorsum so 

 that nearly all the rings are faintly edged and the fourth with a broad 

 band, and in having no black in the ample caudal tuft, which is deep 

 reddish orange. 



Ihavecompared the moth with Henry Edwards's description of ^geria 

 and conclude it is his ^geria corni, although one cannot be positive 

 without comparing the type. He had before him only one male taken 

 in Purgatory Swamp, Mass., and the description is not all that could 

 be wished. My specimens differ slightly from the description and vary 

 considerably, frequently more than some of Mr. Edwards's species differ 

 from one another. I will point out some differences which it seems to 

 me are easily reconciled. He gives expanse of corni 15™'" ; the smallest 

 of mine (males) is 15™™, the largest 18™™, average 17™™; he says "no 

 bands;" some of mine are scarcely banded after storage in the cabinet a 

 month; he says spurs light orange, in mine they are not — the only real 

 difference between his descriptions and my moths. 



Before our next annual meeting I shall try to compare my moths with 

 the type and shall take pleasure in reporting the results. 



Is the moth an inquiline ? It would seem so ; yet after much searching 

 I have found only one beetle borer that would probably serve as a fore- 

 runner. This was found in an excrescence of Acer dasycarpuni. The 

 JEgerian is far more abundant in Acer saccharinum. 



jEgeria rubristigma, n. sp. — Whilst searching in excrescences on the 

 oak for examples of JEgeria gallivora, I came upon the present species 

 which is less common than gallivora. It is a perfectly distinct species 

 and apparently undescribed ; hence, I propose to describe it under the 

 name given above. One male and one female obtained. 



Female : Fore wiugs pui-ple black with red scales between the veins and the square 

 stigma at end of cell red ; borders of hind wiugs very narrow, costa reddish ; fringes 

 ample, black, yellow at basal third of inner margin of hind p;iir ; beneath fore wings 

 yellow to stigma which is deep orange, beyond the borders and veins black with 

 reddish between; hind wings with costa yellow, also anterior third of inner margin. 

 Head all blue-black with milk-white lines before the eyes ; collar yellow ; palpi with 

 basal joint black, second black except the front margin which is yellow as is the 

 whole of the third joint; the antennae are wholly black except the under side of the 

 basal ring which is yellow. Thorax— uniform blue-black with color extending upon 

 the base of wings; metathorax golden yellow ; beneath, color as above with alight 

 yellow, almost white, spot under the insertion of the wings. Abdomen concolor- 

 ous with thorax above and below ; the second segment has a narrow dorsal band, the
