264 LEPIDOPTERA. 



there is no 3'ellow band on the fore-wings, though, sometimes, 

 each eye-like spot is surrounded by a yellowish diffuse ring. 



Xeonympha Enrytris Fabr. flies low, Avith a jerky sort of 

 motion, in thick Avoods, in June and July. The larva is like 

 that of S. Alope, Avhile the clnysalis is shorter with the head 

 obtusely rounded. The adult is dark brown, with two black 

 eye-spots, pupilled with a lead-colored dot, and surrounded 

 Avith an ochre-^'elloAA' ring. On the hind A\ing is a smaller, simi- 

 lar spot. It expands one and seAcn-tenths of an inch. 



The aberrant genus Libythea, Avith its long, snout-like palpi, 

 reminds us of the Pyralids. It is small and the wings are 

 U'regularl}^ notched. L. Baclimanii of Kirtland is not a common 

 butterfly. It occurs southward, and in Central America is re- 

 placed by L. carinenta. 



The small, delicate Theclas and LA^ca^nas are often of great 

 beaiity and interest. The palpi are elongated, the AAings 

 entire, and the hind pair are often once or double tailed. 

 The larA'se are slug-like, as when m.oA-ing on their short feet, 

 sixteen in number, the}" seem rather to glide than walk. They 

 are OA^al, flat lielow and rounded aboAC, both extremities being- 

 much alike, Avith the small head reti-acted Avithin the body. 

 The short and thick chrysalids are flat beneath, but A'ery con- 

 A-ex aboA^e and rounded at each end. Chrysojiltanus Ameri- 

 canics Harris, our most abundant form, is coppery red aboA'e. 

 Its green larA'a feeds on the sorrel, and there are three broods 

 of butterflies in the year. The chrysalis is usually suspended 

 under a stone. One sent by Mr. Saunders, is smooth, Avith 

 no fine hairs. The head and thorax, including the wings, is 

 dull reddish brown, dotted Avith black ; the abdomen is much 

 lighter cinereous, with A^ery distinct, and irregular black dots, 

 and a lateral row of twin black dots, one dot being a little 

 behind its mate. On the middle of the back are three rows of 

 smaller black dots. It is .45 of an inch in length. Chryso- 

 phamts Thoe WestAA-ood is quite a rare species. Mr. Saunders 

 describes the eggs as being "nearly round, a little flattened at 

 the apex and flattened also at the base, Avhere it is fastened to 

 the box. They are greenish Avhite, and thickly indented ; at the 

 apex is a considerable depression ; immediately around this, 

 the indentations are small, groAving larger toAvards the base."
