themselves. When weaving, the larva made a circnlar motion with its 

 head; all the time advancing slowly, and the resnlt was a succession of 

 loops like figs. 8. 



I have now bred from the egg every species of Neonympha found east 

 of the Mississippi River and north of Texas to the Rocky Mountains, in 

 all cases but Caiithiis obtaining chrysalids. These species are Eurytris, 

 Sosybius, Ar col at us, Gciiivia and Canf/n/s/' Oi Henshaiuii I received, in 

 summer of 1881, eggs from Mr. Doll, in Arizona. They were dead, and 

 no larva; had l)een hatched. The shape of the egg was like that of Caii- 

 t/ius, but there was a fine net work of lines over the surface, as in Gemma. 

 In fact, the eggs of the six s])ecies spoken of are alike in shape, almost 

 globular, flattened at the bottom, and all l)ut Cauthus show distinct 

 reticulations over the surface. The larvfe fall into groups, Canthus and 

 Gemma forming one, then Arcolatus one, Eiirytris one, Sosybius one, this 

 last coming nearest tlie true Satyrids (AloJ>c, Szc). The heads of the 

 young larva\ from egg. are round, or truncated ovoid, and except Sosybius, 

 all have processes on vertices at tliis stage. Gemma begins with a pair of 

 high, divergent, conical horns. At first moult, these are of same descrip- 

 tion, but higher in ])roportion, and tlie horns are retained to last stage. 

 Cauthus, at first, has on each vertex a depression, and out of the middle 

 of this rises a low cone. But at first moult, the larva takes on a pair of 

 long, conical horns, and carries them through all stages. Areolatusht'gxw'^ 

 with an ovid knob on vertex, and two others smaller down each side of 

 face. At first moult, there is a low cone on vertex and those on face are 

 suppressed. And essentially the same sort of process runs through all 

 subsequent stages. In the last, it is small, short and pointed. Eiirytris, 

 at first, has a round liead. shaped like a Satyrus, but on vertex is a 

 rounded knob. After first moult the shape of head changes to the Neo- 

 nympha type, sub-ovoid, truncated, and the knob is continued. Same in 

 next two stages, but at fourth moult (and last) these processes are a little 

 longer, pointed and compressed. Sosybius l)egins with a round head, no 

 processes on vertex, and goes through all stages in same manner. Canthus 

 and Gemma are long and very slender, and both change from green to 

 brown when about to hybernate, and back to green again after the hyber- 

 nation, and before a moult. Arcolatus also is long and slender. But 

 Eurytris and Sosybius are stout, and more in shape like S. Alopc. The
