Larva. — Body noetuifoini, tapering toward each end; smooth, entirely uiiarincd. ITcad 

 rounded, snioolli, \vi:h :i bhiek strijie on eacli sside. Body with a suhdor.sal yellow line on eat'h 

 side of back, otherwise i)ale green, or with several dorsal pink patches. 



Freshly hatched larva with a large round head, wider than the elongated body, which tajiers 

 toward the end; segments smooth, sutures deeply impressed; glandular hairs short, minute, 

 ending in three prongs; no lines or spots. 



Cocoon. — Slight and thin, spun between leaves. 



Pupa. — Flattened, oval, rounded obtusely at each end; creniaster obsolete, with no traces of 

 spiues. Color darker than usual. 



Geonrapliical (lisiribittiou. — The species range throughout the Appalachian Subprovince into 

 the Hudsonian fauna, and westward occur in the Campestriau Subprovince. None have yet been 

 found south of the thirty-second parallel of latitude, cither on the Atlantic or Pacitic slopes of the 

 continent. The genus also extends over Europe, being represented by a single si)ecies ( (1. crciuila) 

 which inhabits England and Europe, extending eastward into central Russia and doubtfully into 

 ^jjain. One si)ecies {C. liturata Walk.) inhabits Silliet and India (Madras). 



It is divided into two sections, as follows: 



SYNOPSIS OF THE SPECIES.

II. Thorax usually with a tuft; head rather small; palpi feeble; the two branches of the snbco.stal vein of 

 hind wings long.

A dorsal thoracic tuft, aud a bright, distinct basal and discal sjiot G. screra.

 latter.
