They were at first greenish, getting darker, with a light chest- 

 nut head, as in young C. rclicta larvae. True and pro-legs con- 

 colorous with the body. After the first moult, the larva is al- 

 most black with fine longitudinal whitish lines, the dorsum being 

 a little lighter than the sides. Head dark brown. True legs 

 brown. Pro-legs black. A white dorsal streak just back of 

 the head and another one on the top of the last three or four 

 body segments. After the second moult the caterpillar has a 

 yellowish brown dorsum and a dark lateral stripe. Body mark- 

 ed longitudinally. Head dark, flattened as in cara, lobed above 

 and streaked. Yellowish lunules at the lobes with dark dot in 

 the crescent. Body and head streaked longitudinally but indis- 

 tinctly. True legs lighter than the lateral stripe. Pro-legs dark 

 with dark yellow. A cross black ridge over the 5th abdomi- 

 nal segment. The ridge over the 8th abdominal segment not 

 distinct. Ventral side cream color with intensely black spots. 



After the third moult, the larva is one and one-half inches 

 long, light yellowish brown with a reddish yellow cross band, 

 inclosing the orange hump over the 5th abdominal segment. 

 Hump with a dark line encircling the base. Black dashes at the 

 pair of dorsal tubercles over the 8th abdominal segment. Pro- 

 legs body color with yellow central surface. True legs, red- 

 brown. Head, gray with brownish lateral dash and reddish-yel- 

 low spots at the lobes above, and flattened as in cara. Tuber- 

 cles reddish. Larva very much like that of cara. Whitish be- 

 neath and with black round spots. Short lateral fringe. At 

 this stage of its life, the larva of concumbens is hardly distin- 

 guishable from that of amatri.v at the same stage. 



After the fourth moult, the larva is less than two inches 

 long, dark yellowish-brown about the middle and dark brown 

 about the anterior and posterior ends. The tubercles are deep 

 red-brown with yellowish tops. Head flat as in cara, colored 

 like the body, with red lunules at the lobes above and shaded on 

 the outside by black dashes that extend from the mouth en- 

 tirely around above. True legs, flesh red. Pro-legs, body color 

 with indistinct light spot outside. Over the 5th abdominal seg- 

 ment is a cross elliptical raised yellow place or hump surround-
