 and the arms are roughened; each segmental line is completely 

 encircled by a row of small, chitinous, rounded dots.

Pupa {fg. 8). — Light amber yellow; semitransparent, with the 

 thorax shining and the abdomen rather dull and cylindrical. The 

 antenna! capsule annulatecl, more reddish yellow in color; there is 

 a deep groove between the bases of the antennal capsules; no horn- 

 like projection at base of capsule; at the dorsal base of each antenna 

 is one long yellowish, bristle-like hair ; the plate or area back of the 

 antennae has two raised parts on each side; three oceliar punctures 

 present; to the outer side of these punctures, on each side, is a 

 group of about 15 long yellow bristle-like hairs; postero-dorsal 

 suture of the head is sinuous and marked by about a score of elon- 

 gated, narrow depressions. The thorax is much longer than wide; 

 near the anterior end of dorsum is a transversely arcuate row of 

 punctures, which are larger toward the middle of the row, and near 

 its posterior end is a sinuous suture vrith numerous elongated narrow 

 punctures in front; the anterior or prothoracic spiracle (fig. o) is 

 deep reddish yellow with several wrinkles which are much darker in 

 color, and it is located at the outer anterior angle of the thorax; 

 spiracular slits light yellow, radiating and arranged in a sinuous 

 row whose ends are bent toward each other and nearly touching; on 

 each side of the thorax, near the transverse middle line, is a large 

 bristle-like hair; just back of this hair and above it are two similar 

 hairs; near the posterior end of thorax is a sinuous suture having 

 numerous, elongated, narrow punctures along its anterior edge; and 

 near the posterior angles of the thorax, on each side, are two 

 bristles. Abdomen cylindrical or occasionally depressed, composed 

 of eight nearly equally long segments; segments from 1 to 7, on 

 each side, with a shining reddish j^ellow spiracle (fig. ^.) similar 

 in color to the prothoracic; below each abdominal spiracle is a spine- 

 like bristle ; first segment with a transverse roAV of widely separated 

 bristles along the posterior edge; these bristles are more numerous 

 toward the lateral end; posterior margin of segments 2 to 7 with a 

 row of closely set bristles which are longer laterally; each of the 

 segments fr-m 2 to 7, w\i.en iully extended, has a broad transverse
