HELICONIA I. 
Body above black ; beneath, the thorax black with an oblique yellow side 
stiipe; a yellow macular stripe on side of abdomen and two yellow lines below; 
the edges of the segments more or less yellow; under side pale salmon color; a 
red spot on either side of abdomen next the wings; four yellow spots across 
thorax and a bar behind them ; two rows of four small yellow spots back of the 
head ; legs black with dull yellow scales, the aborted pair bright yellow; palpi 
yellow with many long black hairs in front, the upper side at tip black; antennae 
and club black. 
Female. — Expands 4 to 5 inches; similar in color and markings to the male. 
The species is subject to considerable variation : one example submitted to 
me has a patch of yellow on primaries between the two lower bands. (Fig. 6.) 
Another has the spots of hind wing pure white on both sides (Fig. 5): and 
there is much difference in size, some being dwarfed. (Fig. 4.) 
Egg. — Cylindrical, one half higher than broad, flat at base, tapering very 
slightly fiom base to about three fourths the length, then conoidal, the top flat¬ 
tened and a little depressed ; marked by fourteen vertical ridges, straight, nar¬ 
row, not very prominent, extending from base to the middle of the cone°; below 
the cone are horizontal low ridges which, with the vertical ones, inclose long, 
rectangular spaces ; there are nine tiers of these, each space being roundly ex¬ 
cavated ; next above the base of the cone is a tier of similar spaces, but higher, 
more nearly square, and more deeply excavated ; next are seven cells, irregu¬ 
larly pentagonal. The flattened top is composed of three concentric rows of 
spaces, pentagonal, except the innermost, which are rhomboidal; color yellow. 
(Fig. a, « 2 .) Duration of this stage three days. 
louNG Baeva. — Length .08 inch; cylindrical, segments 2 to 7 of about even 
thickness, then tapering, the dorsum sloping; marked by four principal rows 
of rounded and flattened tubercles, of which two are dorsal, and one is on either 
side; the former extend from 3 to 13, the latter from 3 to 11, each tubercle 
standing on the middle of the segment; there are also two rows of similar but 
minute tubercles, one lying between the dorsal and lateral, each tubercle placed 
at the junction of the segments from 2-3 to 12-13, with another at the end 
of 13; and one over feet, two tubercles to each segment in longitudinal line 
fiom 2 to 10, and one from 11 to 13; on 2 is a chitinous dorsal band with tuber¬ 
cles ; a rounded tubercle on side in line with the lateral body row, but small; 
and near the front of the segment two others, one upper, one lower; each 
tubercle, wherever placed, sends forth a black tapering hair, those from the main 
lows long, and on dorsum, on the three anterior segments, bent forward, on the 
next three or four erect, the rest recurved; of the side rows, both large and
