MELITJiA I. 



Body a])Ove black, the abdomen with a dorsal and lateral row of yellow points; 

 beneath, the thorax black ; the abdomen black, with yellow at the junction of the 

 segments, and with a fulvous stripe on either side ; the extremity also fulvous ; 

 legs and palpi fulvous; antenna? black, slight!}- ringed with yellow on the upper 

 side ; club black, tipped either with fulvous or with black and fulvous. 



Female. — Expands 2.2 inches. 



Primaries less produced and broader than in the male; paler colored, similarly 

 marked. 



Egg. — Ob-ovate, truncated, rounded at base, flat or slightly depressed at sum- 

 mit, smooth ; the upper third marked by from twelve to eighteen vertical ridges 

 Avhich spring from the surface, increase in elevation as they proceed, and ter- 

 minate at the edge of the flattened summit ; color lemon-yellow when first 

 deposited, changing in a few days to dull crimson, and shortly before the dis- 

 closure of the larva to black. Duration of this stage nineteen or twenty days. 

 (Fig. b, egg magnified.) 



Young Larva. — Length, .08 inch ; cylindrical, translucent, luteous, each 

 segment showing a transverse row of brown tubercles, which indicate the posi- 

 tion of the future spines, each giving a pencil of light hairs ; legs brown, pro- 

 legs luteous ; head broader than the body, obovate, bilobed, brown. Time to 

 first moult six days. (Fig. e, larva magnified.) 



After first moult : length, .16 ; shape as before ; color dull luteous, the ex- 

 tremities dusky ; from each tubercle arises a short black fleshy spine, which 

 bristles with light hairs; head blackish-brown. To second moult six or seven 

 days. (Fig. d. magnified.) 



After second moult : length, .3 inch ; the spines longer, the bristles larger 

 and black ; color either ochraceous or brown, the segments at either extremity 

 black ; head black, much covered with short black hairs. Duration of this stage 

 nine to ton days. (Figure omitted accidentally.) 



After third moult : length .35 ; the spines longer, black, .shining, each spring- 

 ing from a glossy black tubercle, the bristles radiating and interlacing ; the 

 extreme segments black, the others dark yellow-fulvous, with black stripes ; 

 head black. Lnmediately after this moult is completed, the larvae cease feeding 

 and become lethai'gic, in which state they remain till the following spring. 

 (Fig. e, larva natural size ; e^, magnified.) 



The fourth moult takes place a few days after animation is restored ; length, 

 .6 inch ; scarcely changed in appearance from last stage ; color dull yellow-ful- 

 vous. Time to next moult about ten days. (Fig. /", natural size.) 



After fifth moult : length, .8 inch. The growth is now rapid, and in a few 

 days the larva reaches maturity. (Fig. g.)
