 CIODES CARLOTA, REAKIRT (CHARIDRYAS 

 ISMERIA, SCUDDER). 



BY WM. H. EDWARDS, COALBURGH, WEST VA. 



Egg. — Pear-shaped, broad at base and rounded, tapering rapidly to a 

 small, slightly depressed, truncated summit; marked by about twenty-four 

 low, vertical, not sharply defined ribs, which extend a little more than 

 half way from the top to base, but vary iri^ individuals ; below the ribs to 

 base thickly covered with shallow and irregular (both as to size and shape) 

 indentations, not separated by definite ridges or threads ; colour, when 

 laid, pale green. Duration of this stage, nine days. 



Young Larva. — Length, at one day from the egg, .08 m. ; cylindrical, 

 even, each segment rounded, with black hairs or processes rising from 

 concolored minute tubercles, arranged as in Tharos and Nycteis ; colour 

 green with a tint of brown ; head scarcely broader than 2 ; obovoid, bi- 

 lobed, black-brown, with many short and curved black hairs over the 

 face. Duration of this stage, between two and three days. 



After first moult : length, at one day, .12-inch ; each segment rounded ; 

 colour variable, either dark-brown altogether, or light yellow-brown with 

 a darker sub-dorsal stripe; under side, feet and legs, yellow-brown; armed 

 with spines as in the genus, these being small, conical, shining black, with 

 black bristles about the sides, and one larger at the top ; head nearly as 

 before. Duration of this stage, three days. 



After second moult : length, at one day, .18 to .20 inch ; shape as be- 

 fore, the spines somewhat longer in proportion ; colour variable, some 

 being wholly yellow-brown, some light-brown (not so yellow), and both 

 these types sometimes have a dark-brown sub-dorsal stripe ; some are all 

 dull green, and some are pale black, a little mottled with gray ; the 

 spines are black and rise from small shining black tubercles ; head as be- 

 fore. To next stage, from two to three days. 



After third moult: length, at one day, .3 inch; same shape; the 

 lower lateral spines brown-yellow, the upper rows black, and in shape as 

 before ; colour variable, some being light yellow-brown, with a dark sub- 

 dorsal stripe, some brown-black, with a patch 01 red-fulvous on dorsum of 

 2 ; others have a mid-dorsal row of such patches, one to each segment ; 

 others are reddish-brown ; in all the lower half of the side is different from 

 the upper part, being either greenish-brown, mottled more or less with 

 whitish, or light brown and so mottled, but without green ; head as before.
