ground color. Stigmatal line absent; spiracles brownish, pale 

 ringed. In the incisure, between the joints 5 and 6, is a black 

 band, edged with yellow, anteriorly, concealed when the larva is 

 at rest, but suddenly exposed when the presence of an enemy is 

 suspected. 



Fifth stage. — Head rounded, the sutures deep, minutely wrin- 

 kled and clothed with very short pile; pinkish brown, whitish 

 around the mouth; ocelU black; width 3.8 mm. Body entirely 

 smooth, uniform soft green, whitish at the sides and beneath, and 

 minutely, but obscurely dotted with yellowish; joint 2 is yellow 

 anteriorly around the slit for the scent organ. The marks on 

 joint 4 are without tubercles, and consist of a rounded triangular 

 orange spot in a black edge, below it a pale blue dot, then a black 

 edged pyriform spot, very slightly excavated in front and pro- 

 duced on its lower posterior side, divided above the middle by a 

 transverse black line (above which it is orange, below yellow) 

 and containing a violet dot in a broad black border. As the 

 stage advances this mark becomes terra cotta color, except the 

 lower part of the pyriform spot, which is yellow, shaded with 

 terra cotta. In the fold between joints 5 and 6 is a black band 

 edged with yellow anteriorly, reaching over the dorsum to the 

 lateral region on each side. On joints 5, 9, 10 and 11 deep blue 

 dots represent the former tubercles of rows i and ii; on joints 5 

 to 12 a subsiigmatal row of deep blue dots and on joint 5 a sub- 

 dorsal and lateral pale blue dot. Spiracles small, white, sur- 

 rounded by a broad brownish border; scent organ orange. 



Chrysalis. — Cylindrical, the abdomen tapering, no depression 

 between thorax and abdomen, a blunt trigonate thoracic promi- 

 nence projecting forward parallel, with a similar process over

 row of subdorsal abdominal granular elevations, tljree of which 

 are most distinct. Color wood-brown, longitudinally streaked 

 with olive-brown; wing-cases grayish; a subdorsal line of deep 

 brown shading over the dorsum, continued as a broad shade to 

 the end of the thoracic projection; a broad, lateral, similarly 

 colored band, extending the whole length, diffuse on its upper 

 edge; a brown shade on the wing-cases basally, below the cell 

 and a greenish shade on the leg-cases. Length 35 mm. ; width 

 9 mm.
