170 JOHN B. SMITH. 



In the % genitalia the supra-anal plate shows no important differ- 

 ences from that of celem, save that the hook is less curved ; the side 

 pieces are rather narrow, elongate, the tip narrowing and obtusely 

 rounded. The clasper is a long, tapering, sinuate prong, with the 

 edges serrate ; very different from anything else in the genus. 



The larva has been figured by Smith and Abbot, and subsequent 

 authors have copied from them, so far as I can find. Burmeister 

 gives a brief, original description from Brazilian specimens.

The head and thorax above are grayish brown ; palpi somewhat paler above, 

 white beneath. Collar with two transverse black lines; patagise edged with 

 black and with a black line through the middle, below which they are gray; 

 metathoracic tuft? black, edged in front with blue and behind with yellow. Ab- 

 domen with dorsum broadly brownish gray, with an interrupted brown dorsal 

 line; there are five rosy, oblong, lateral spots, decreasing in size posteriorly and 

 separated by black bands. The sides of the thorax, abdomen and all the legs are 

 of a lighter gray color, while the under side of the body is whitish, with a row 

 of three or four black sj)ots along the middle of the under side of the abdomen. 

 Primaries dark brownish gray, with a small gray spot at the base. The discal 

 spot is small, reniform, pale gray and encircled with black. A series of three or 

 four angulated, blackish brown lines cross the wing basally and inside the discal 

 spot, and a series of three similar lines crosses the wing beyond the discal spot, 

 outwardly angulated below the cell and reaching the internal margin about one- 

 third from anal angle; along the outer of these lines is a grayish white accom- » 

 l^anying shade. These two sets of lines are joined by a dark brown shade with 

 two black dashes in it below the cell, thus forming, with the upper and darker
