darker medio-dorsal stripe the row of white tubercles forms quite a broad 

 stripe, another one at edge of dorsum, and another at base, over feet ; 

 the head emerald green, shaped as before. To next moult 5 days. 



After 4th moult — Length .56 incli. Without another moult this stage 

 continued till maturity. 



Mature Larva — Length .76 inch. Cylindrical, obese, thickest in the 

 middle, rounded dorsally, and sloping slightly to 11, then rapidly to last 

 segment, which ends in forked, divergent tails ; color emerald green, much 

 covered with fine yellow tubercles placed on the ridges caused by the 

 creasing of the segments, and with larger tubercles disposed in longi- 

 tudinal rows ; each tubercle giving out a fine and short white hair ; at 

 base of body tlie stripe is more heavily tuberculated than on dorsum ; on 

 either side of a clear, dark green, medio-dorsal stripe is a tuberculated 

 stripe, and another at edge of dorsum ; under side, legs and pro-legs, nearly 

 same green as above ; head rounded, broader than high, bilobed, and but 

 little depreseed at the suture, somewhat flattened frontally, broader than 

 2, equal to 3 ; covered with yellow, conical, fine points, arranged in close 

 vertical rows, and at same time in transverse rows also ; the ocelli black, 

 mandibles brown. 



The larva suspended in form of figure 6. Duration of this stage 7 

 days. 



Chrysalis — Length .4 inch ; greatest breadth .1 inch. Cylindrical, the 

 abdomen stouter than anterior portion ; mesonotum rounded, carinated ; 

 the head case truncated, scarcely projecting beyond the mesonotum, 

 slightly arched at top, narrow, beveled at corners ; the wing cases flaring 

 a little on dorsal side, the neuration of wings seen distinctly ; color green, 

 on the abdomen yellow-green ; on either side of dorsum on abdomen is a 

 small ridge, and on either side of this are three black dots, placed in pairs 

 between the mesonotum and extremity ; on either side below wing cases 

 a brown stripe ; the keel of mesonotum brown, and the wing cases are 

 crocked along the principal nervures, and on the margin is a black dot at 

 the end of each nervule. Duration of this stage 13 days. 



This species is very common in this part of West Virginia, and is 

 found over the Southern and Southwestern States and in Mexico. Here 

 it is two brooded. It flies in company with gemma and eiiryiris, keeping 

 within the edge of the forest, or if in the open country, is always near 

 timber. The egg is shaped very much like that of eurytris, but still more
