IIELICONIA I. 



Body above l)lack ; beneath, the thorax blaek with an obhque yellow side 

 stripe; a yellow maeular stripe on side of abdomen and two yellow lines below; 

 the edges of the segments more or less yellow : luulei' side pale salmon eolor ; a 

 red spot on either side of abdomen next the wings; tour yellow spots aeross 

 thorax and a bar lyehind them ; two rows of four small yellow spots baek of the 

 head; legs blaek with dull yellow scales, the aborteil pair bright yellow; i)alpi 

 ^■ello^v with many long blaek hairs in front, the upper side at tip blaek ; antenu;u 

 and club black. 



Femalk. — Expands 4 to "> inches; similar in color an<l markings to the male. 



The species is subject to con.siderable variation : one example submitted to 

 me has a patch of yellow on primaries between the two lower bands. (Fig. i\.) 

 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 tlinn broad, ilat at base. tai)ering very 

 slightly from 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, whli the vertical ones, inclose lonu', 

 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 llattened top is composed of three concentric rows of 

 spaces, pentagonal, except the innermost, which are rhomboidal ; color yellow. 

 (Fig. o, «".) Duration of this stage three days. 



Young Larva. — Ijength .08 inch ; cylindrical, segments '2 to 7 of al)out even 

 thickness, then tapering, the (U)rsvim 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 ■! 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 juncticni of the segments from l2-3 to 11^-13. with another at the end 

 of 13; and one over feet, two tubercles to each segment in longitudinal line 

 from 2 to 10. and one from 11 to 13 ; on 2 is a chitinons 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 

 vows long, and on dorsum, on the three anterior segments, bent forward, on the 

 next three or fom- t>rect, the rest recurved ; of the side rows, both large and
