The variety carolinti from southern Florida differs from the t3^pc 

 form in that all the brown spots of the fore wings are smaller and 

 narrower. I have eon-fine from Mexico and Venezuela, and they con- 

 stantly differ from the Floridian specimens hy the larger, more rounded 

 spots, contrasted on the more whitish, less unii'ormly ocherous- tinted 

 ground color. The larva of the stem form has not been described, so 

 no comparisons can ])e made. Our larva is a true Syntomid. 



Egg. — Shape of two-thirds of a sphere, rounded, smooth; white, 

 translucent, with a pale green tint, not shining. Reticulations small, 

 irregularly hexagonal, slightly raised, about alike all over, distinct; 

 diameter, 0.9 mm. Laid singly on or adjoining the food plant. 



Stage T. — Head slightl}' bilol)ed, whitish testaceous, clypeus high, 

 ocelli ))lack, mouth brown; width, 0.4 mm. Body all white, the shields 

 concolorous, tubercles' large, arctiiform, faintly slat^^ Feet normal, 

 arctiiform. Setje long, stiff', pale, ii black as well as iii, l)ut posteri- 

 orly the long black hairs have pale tips. Warts i to v present, sin- 

 gle haired, no subprimaries; leg shields pale slaty like the tubercles; 

 i and iv small. On the thorax ia+ib+iia, large, iib separate, pos- 

 terior, small. Cervical shield small, reduced, concolorous. Seta3 ia 

 and ib of joints 3 and -1 are black, iia white, l)ut all on a single wart 

 with a projection behind. Later the larva is pale yellowish, the food 

 faintly green; tubercles pale, a little darker on the rims. Joint 2 

 retracted and with very weak shield; no anal plate. 



Stage II. — Head rounded, slightly bilol)ed, pale greenish yellow, 

 ocelli narrowly black; width, 0.5 mm. Body arctiiform, normal, pale 

 yellow, a dark shade from the food. Warts large, perfectly concolor- 

 ous; hairs long, straight, and rather stiff, deep black and pure white 

 mixed, black predominating dorsally, white subventrally. Joint 2 

 small and retracted; joints 3 and 4 rather large. Feet all pale, no 

 shields. Only one subdorsal wart on joints 3 and 4; wart i of abdo- 

 men small, as also iv and v, but all several haired. Toward the end 

 of the stage traces of a double white dorsal line appear. 



Stage III. — Head broad, round, bilobed; clypeus reaching about
