wardly-directed spine-like tooth followed after a slight interval " by a 

 lamina, the free edge of which is concave and spinulose, and ends at 

 about two-thirds the appendage-length in a second spine-like tooth, 

 longer and more acute than that near the base, beyond which the 

 appendage is moderately slender with a blunt apex ; middle third of 

 the outer edge of the appendage denticulate. In profile view the 

 upper edge of the appendage is slightly concave, or almost straight, 

 for the proximal two thirds, curved downward for the apical third; 

 the basal tooth and lamina of the inner margin are visible on the 

 lower edge, apex truncated. 



Inferior appendages in dorsal view reaching to the apex of the 

 second, more acute tooth of the superiors ; pale brown, abruptly nar- 

 rowed on the inner edge at half-length ; distal half as wide as proxi- 

 mal, of uniform width, or slightly enlarged in terminal fourth ; apex 

 rounded, with pale hairs. In profile view they rapidly taper to half 

 length ; distal half slender, directed upward. 



Legs yellow, femora with a superior and an inferior longitudinal 

 line, tibiae with an inferior longitudinal line and the tarsi blackish. 



Wings almost clear, stigma surmounting two cells or a little more, 

 brown to dark brown, proximal and distal edges parallel, paler ; 10-14 

 postnodals on the front wings, 8-1 1 on the hind. 



Older. — A blackish line bounding each side of the reddish mid- 

 dorsal thoracic stripe, beginning one-third of the way from the anterior 

 mesothoracic margin, and ending at five-sixths of the way ; a narrow 

 black stripe along each side of the mid-dorsal thoracic carina, but 

 leaving the carina itself pale, mesepimeral stripe blackish. (Chapada, 

 icT, abdomen 26.5 ; hind wing 16 ; costal edge of stigma, front wing, 

 1.2 mm. ) 



Oldest stage seen. — Prothorax blackish dorsally, with a pair of 



arcuate pale green stripes on the middle lobe, front lobe pruinose ; 



each of the blackish lines bounding the reddish mid-dorsal stripe of 



the preceding stage widened to a stripe .3 mm. wide at mid-height, 



where it is distant from the mid-dorsal carina by nearly .2 mm., not 



reaching the anterior mesothoracic margin below, nor the antealar 



sinus above ; area between the two black stripes more greenish than 



reddish ; black mesepimeral stripe continued down upon the mesin- 



fraepisternum, metasternal black stripe widened so as to reach almost 



11 In one male referable to this stage there is no interval and the basal tooth appears 

 to be fused with and forms the beginning of the lamina.
