Pupa heretofore undescribed, but Hill (1925:

simple or rarely two-forked; 7 medium, simple 
or two-forked. 
Dorsal: 8 small, about one-fourth length of 
trumpet, three- or four-forked, rarely five- or 
six-forked. 
Supra-alar: 9 long, two-thirds length of trumpet, 
simple. 
Metanotum: 10 medium, two- or three-forked; 
11 long, simple; 12 long, simple or rarely two-

Trumpet: Short, length about three times great- 
est diameter of meatus; pinna long, about one- 
third of total length of the trumpet; base slightly 
darker than apex; tracheoid area obsolete. 
Abdomen. — Segment I: h medium, simple; 
K long, simple; L small, two- or three-forked, 
rarely four- or five-forked; M small, three- 
branched or rarely two- or four-branched; S long, 
simple, very rarely two- or three-forked; T long, 
two-forked near basal one-third or simple; u 
small, simple. 
Segment 11: A small, simple spine; B long, sim- 
ple; C medium, most often seven-branched, 
range from five to twelve; c' small, simple spine 
on this and all following segments; 1 long, two- 
forked, rarely simple; 2 medium, simple or 
rarely two-forked; 3 small, two- or three-forked,
