HELIC0N1A I. 
irregularly placed ; the dorsals measure .2 inch, the 1st laterals .17, the lower .14 
inch, and there is little variation in the length of the spines of each row; le^s 
brown, tipped black, pro-legs brown, with a black spot on the side of each; head 
obovoid, rounded in front, truncated, a little depressed at the suture, the vertices 
but little elevated, rounded; color greenish-white, vitreous; on either side the 
suture on mid-front a round black spot; the ocelli black on a small black patch ; 
mandibles black ; on each vertex a black spine nearly like those of the body, but 
less tapering and more blunt, .12 inch long, directed forward at about 45°, and a 
little recurved. (Fig-/?/ 2,3,4 .) 
As the larva approaches suspension the spots change to brown, and the white 
becomes dull and sordid. Twelve hours after suspension, pupation takes place. 
Chrysalis. Length to top of head .95 inch, to end of processes on head 1.1 
inch; slender, compressed laterally, the thoracic segments on ventral side highly 
arched and rounded abruptly down to abdomen; the sides of this elevation 
covered entirely by the wing cases, sloping, almost flat or a little convex, the two 
wing cases not quite meeting, but separated by a narrow depressed ridge, on 
either side ot which is a row of small bead-like tubercles, each giving out at top a 
short sharp bristle or thorn ; this ridge widens anteriorly so as to include the an¬ 
tennas cases, and the rows of beads pass along and around head case to its top on 
the dorsal side, but for a little distance at the base of the antennas lose their bris¬ 
tles, head case prominent, compressed transversely, nearly square at top; upon 
each vei tex a narrow leaf-like process, lanceolate, flattened and thin, serrated on 
both edges, divergent, like horns ; mesonotum prominent, compressed at top into 
a thin carina which rises on the anterior part in a double curve to a sharp point, 
but on the postenor side slopes at about 45 ; followed by a rounded excavation 
considerably longer than the mesonotum itself ; abdomen cylindrical; on the two 
upper segments a large sub-dorsal, flaring, flattened process rounded irregularly 
on the edge and completely spanning both, segments; on the next segment is a 
small sharp rounded process, and on the next another small and flattened ; on the 
next a sharp tubercle, in some cases flattened ; on the tops of all these processes 
are thorns, one on each of the smaller, and two on the largest; in row with these, 
on the depression and on the sides of mesonotum, are four low conical tubercles, 
each with a short thorn; segments 9, 10, 11, in the ventral line, have the ante¬ 
rior edges turned up and produced into low divergent points; at the base of the 
head case on dorsal side a large burnished gold spot, and the tubercles behind the 
mesonotum gilded ; general hue brown, in shades ; the anterior parts, which in¬ 
cludes head case, mesonotum, and half the wing cases, being light or yellowish ; 
the rest of wing cases dark, or streaked dark in the interspaces of the wings; the 
light part of these cases somewhat gray or whitish; the processes on head and
