an angle of a box in which it was confined ; died without becoming a 

 pupa. 



The above description diifers in coloration from that given by Harris 

 and others. It is possible that the colors may have undergone some 

 change, from its approach to its pupal state, although I can recall no 

 instance where so long a time as two days has elapsed, after the change 

 of color, before the larva has taken its position for pupation — the usual 

 period being about twenty-four hours. 



I have taken the Ima<jo the middle of June, about the fragrant 

 Honeysuckle.

Youwj Larva, after first molting, .50 in. long, light green, yellow late- 

 ral bands running into the yellow subdorsal line. A dorsal series of 

 yellow triangular spots, which on the sixth and seventh segments are 

 centered with orange. Caudal horn green, straight. .20 in. long. It 

 is not until after the last molting that the horn becomes curved. 



Mdture Larva. Head small, oval, with yellow granulations and four 

 yellow perpendicular lines. Body with fourth and third segments 

 swollen, tapering rapidly from the former to the head ; color, yellowish- 

 green, with numerous pale yellow dots. Lateral bands, seven, connect- 

 ing above, with a white stripe, which borders a darker green subdorsal 

 line, extending from the lateral stripes of the head, nearly horizontally 

 to the tenth segment, upon which it curves upward to the horn. On 

 the three anterior segments the subdorsal line is yellow bordered be- 

 neath. Five dorsal spots of pale green, the base of each resting on the 

 anterior of the segment, and the apex on the posterior — having within 

 on the vascular line, a lozenge shaped dull rose spot resting on the an- 

 terior incisure of the segment. Caudal horn .25 in. long, bluish-green, 

 granulated anteriorly with black, posteriorly with yellow, and with a 

 yellow tip. Stigmata orange, with a white spot at each extremity. 



A short time before its pupation, the color of the larva changes to a 

 dull rose throughout, with the white lateral and subdorsal bordering 

 bands of a clearer rose. Previous to this change of color, I have ob- 

 served the caterpillar to pass with its mouth, over the entire surface of 

 its body, even to the tip of its horn, covering it with a coating of appa- 

 rently glutinous matter — the operation lasting about two hours. 



The larva, which occurs on the Grape, is very liable to be stung by
