rounded toward the tip, showing under a lens a marginal row of about 

 ten delicate curved reflected spines on each side, and a larger terminal 

 double hook, by which the pupa is attached to some transverse threads 

 in its cocoon. 2 9 . 



The Imaqo appears early in May, probably as early as diffinu. Boisd. 

 which I have taken May 12th. It is often seen by day, feeding from 

 the blossoms of the Phlox of our gardens, and has been observed to 

 frequent the blossoms of the common Lilac, at twilight. 



Sphinx quinquemaculata Stephens. 



The young larva is of a delicate light green color, acutely granulated, 

 especially when it has recently moulted, resembling in its roughness a 

 Sm<rinthus. 



The mafare larva differs in color in diff'erent individuals to a degree 

 far exceeding any other with which I am acquainted. Its usual color, 

 by which it is generally known from its common occurrence on the 

 tomato, is a dull green, with yellowish-white lateral bands, with a pecu- 

 liar shiny appearance of the skin when at its maximum size. Occa- 

 sionally the following variety is met with : 



Sea-green variety. Head and collar glossy black. Body dull sea- 

 green, with the usual ocellated spots on the annulations almost obsolete 

 posteriorly. The lateral and connecting stigmatal bands, margin of 

 caudal shield, and an elongated triangular spot on the head, flesh color. 

 Legs, exterior of prolegs, caudal shield and plates, shining black. 

 Ventral region lighter green. 



Among a large number of the larvas which were brought me, taken 

 from a field of tobacco, several were found of the following variety, 

 which, from their food-plant and abnormal coloration, I confidently ex- 

 pected to give me the Carolina, but when reared I obtained an Imago in 

 no respect differing from those bred from the ordinary green tomato larva : 



Brown variety. Head black, large, with a triangular drab spot cen- 

 trally, and a lateral linear one. Body, very dark brown, sprinkled with 

 numerous raised yellow dots, showing minute ocellations under a lens. 

 Seven yellow lateral bands. The stigmatal bands yellow. Caudal 

 shield yellow bordered. Tips of legs, collar, caudal shield and plates, 

 glossy black. Caudal horn black, .3 in. long, studded with short spines. 

 Stigmata broadly oval and bordered with violet.
