with no covering. The young larvae consume about half the 

 empty shell. 



Larva. — Body black both above and below in some cases, in 

 others there is a broad, dorsal, velvety-black line, the sides paler, 

 with an indistinct darker lateral line between the first and second 

 tubercles, sometimes followed below by a pale, broken line. Head 

 black. Second segment very short, carrying two black fascicles 

 directed forward, somewhat tufted at the tip, and a few, long, 

 pale hairs between them at the base Segments 3 and 4 are short, 

 with four small, yellowish lateral tubercles on each side, with pale, 

 short radiating hairs. Segments 5 to 8 similar, each with a com- 

 pact yellowish, stiff dorsal tuft or brush, and three lateral tubercles 

 on each side, with pale radiating hairs, that nearest the dorsum 

 orange-colored and conspicuous, the others tawny and obscure. 

 Segments 9 to 1 1 similar. The black dorsal stripe is narrowly 

 edged with pale yellowish, each segment carrying a few pale marks 

 in the black dorsal line. Four lateral tubercles on each side, the 

 two uppermost orange and conspicuous, the others pale. All with 

 pale hairs. Segment 12 similarto 1 1, but only two lateral tubercles 

 on each side, the uppermost orange, and a stifT, vertically com- 

 pressed, black fasicle, directed backward, of which the posterior 

 hairs are the longest. Thirteenth, dusky with long, dusky hairs. 

 Legs brownish. Length, i.oo to 1.25 in. 



The special characters are the black appearance of the larva, 

 the pale marginal mottlings of the dorsal line on segments 9 to 

 12, the hairy orange tubercles, the want of brilliant dorsal fleshy 

 tubercles, and the pale lateral line in pale colored examples. In 

 the black examples, the orange tubercles and dorsal mottling on 

 segments 9-12, are alone conspicuous. 



Lviago. S . — Comparison of 5 <J Badia with 2 6 Antigua re- 

 ceived from Dr. O. Staudinger, reveals such trifling differences 

 that unless the larval differences are considerable, the two forms 

 must be considered one, and as Mr. H. Edwards suggests nova of 

 Fitch must probably share the same fate. My specimens of An- 

 tigua, it is true, are somewhat ..mailer than the five Badia, and 

 there is a browner tint on the latter than obtains on Antigua, but 

 so far the markings on the primaries above are identical in both 

 forms, while the secondaries above and the entire insect beneath, 

 as well as the body parts, show no appreciable difference.
