EARLY STAGES OF SOME NORTH AMERICAN 



LEPIDOPTERA. 

 By Henry Edwards. 



With a view to the publication at an early day of a "Catalogue of 

 the Described Transformations of North American Lepido/tera," which 

 I wish to make as complete as I can, I have prepared the present 

 paper, and I take the opportunity now presented to me, of asking my 

 fellow entomologists throughout the country to publish as quickly as 



ble, any descriptions they may have of eggs, larvae or pupa-, so that 

 the references to them may be made in my forthcoming work, to save as 

 far as may be, their future issuance in the form of an Appendix. The 

 Catalogue up to the end of the Sphingidae is now ready for the printer, 

 but will be kept back until the close of the year, so as to embrace de- 

 scriptions which may be given in answer to this appeal. 



RHOPHALOCERA. 



Synchloe (Coatlantona) Janais, Drury. Chrysalis. 



In form very much like the chrysalis of Melitcea. It is obtusely cylindrical, 

 swollen about the head parts, and tapering abruptly at the 4th abdominal segment, 

 those behind being somewhat bent downwards. The color is dull sordid white, with 

 numerous black dots and dashes. There are dorsal and sub-dorsal rows of raised 

 black points, two raised black points on the thorax, and between and behind them 

 are two liars of black, placed like the sides of a triangle. The sides of the thorax and 

 head are also conspicuously marked with black irregular blotches. On the wing- 

 e several long distinct black streaks, and a row ot black dots marks the course 

 of the spiracles. Underside also strongly marked with black dashes and blots. The
