658 [December 



Head small, flat, suboval, of a clear apple-green, yellowish on the sides. 

 with a lateral black stripe exteriorly. Body apple-green, lighter and 

 of a transparent hue dorsally, deepening laterally. Lateral bands, .seven, 

 confined to one segment each, with a sharply defined bordering anteriorly 

 of dark blue almost black, white centrally, and yellow interiorly. 

 Caudal horn .40 in. long, quite curved, light blue, thickly studded with 

 shining black tubercles, which coalesce at the tip. Caudal shield and 

 anal plates yellow green, dotted with small black elevated points. Stig- 

 mata pale orange — their upper portion extending in the yellow of the 

 bands. Legs black, pearly at base. Prolegs with two black spots ex- 

 teriorly, separated by yellow, or connected posteriorly by a black line. 

 Feeds upon the Lilac {Si/rinya vulgaris and S. Pcrsu-a.) I have 

 taken it ready for pupation, 25th July, and as late as 2Uth September. 

 At least three-fourths of those which I have met with, have been stung 

 by its parasite, the grubs of which eat out of the body and cover it with 

 their cocoons (apparently the same as those occurring on Darapxa 

 3Ji/ro)i), usually just as the larva has attained its growth. 



I regret my inability to give a description of the Pupa. Its exserted 

 tongue-case, from my recollection, in length, is intermediate between 

 ilrupiferarum and cinerea. 



Sphinx Drupiferarum Sm. and Ab. 



Larva. 3 inches long, cylindrical, apple-green. Head green, with 

 lateral brown stripes, uniting at the apex, and becoming broader toward 

 the base. Body, with the lateral bands white, bordered anteriorly with 

 violet, and confined to one segment. Stigmata orange. Caudal horn 

 .40 in. long, dark brown. 



Taken on the Apple and Plum from August 5th to the 25th, full 

 grown. 



Among some notes made by me in 1859, is the following : 



August 1st took young larva of Drupiferarum, feeding on the Plum ; 

 apparently after its second molting, 1 inch long; its body rough with 

 numerous small granulations, more conspicuous toward the head; no 

 (■audal horn. Molted August 4th; granulations less prominent; no 

 caudal horn. Escaped before its next molting. 



I can only account for the above anomaly of the absence of the horn 

 in this species, by the supposition, that it may have been lost by some
