SECOND ANNUAL REPORT OF 



with the knees of the middle pair of legs, it severed and ruplured the 

 thin chrysalis shell, and the very moment the anus touched the rup- 

 tured end, the creamy fluid usually voided by newly-hatched moths 

 was discharged. 



I have never found any parasite attacking this species, but its 

 solitary habit and large size make it a conspicuous object, and it is 

 easily controlled by hand, whenever it becomes unduly numerous 

 upon the Grape-vine. 



THE SATELLITE SPHINX— Philampelus satellitia, Linn.* 



(Lepidoptera Sphingidae.) 



Like the preceding insect this one occurs in almost every Slate in 



[F»s- 52.j the Union. It also bears a strong 



resemblance to the Achoraon 



Sphinx, and likewise feeds upon 



the Ampelopsis as well as upon 



the Grape-vine; but the worm 



% may readily be distinguished 



1 from the former by having five 



r ; cream-colored spots each side, 



J instead of six, and by the spots 



themselves being less scalloped,

i\ this worm is found full grown

the last of October. The eggs 



. of this species, as of all other 



ty Hawk-moths {Sphinx family)

 of the authors above quoted, is distinct from S. SatcMIio, Linn., and would lain "eliminate a 

 third species {posiivatva). For reasons which it would be tedious to give here, 1 prefer to regara 

 lycaon. as a variety of satellitia.
