1858 BUTTERFLIES BEYOND NEW ENGLAND. 



Second stage. Head black ; dorsal thoracic shield blackish castaneous ; body pale 

 greenish yellow, all the legs and prolegs concolorous. Length, 2.75 mm ; breadth of 

 head, .55 mm. From specimens in glycerine. 



Third stage. Colors as before. Length, 4.5 mm. ; breadth of head, .85 mm. From 

 specimens in glycerine. 



Foxirth stage. Head black, densely clothed with delicate pallid hairs. Dorsal tho- 

 racic shield fusco-castaneous. Body green, the legs and prolegs concolorous. Length, 

 8 mm. ; breadth of head, 1.75 mm. From specimens in glycerine. 



Last stage. Head piceous, scabrous, including near the middle of the front of each 

 hemisphere some slightly larger, piceous and smooth tubercles, the pile pale brown. 

 Dorsal thoracic shield testaceous, paling behind. Body green, covered with the 

 minutest possible papillae in the centre of small, circular bits of tougher integument, 

 and bearing the minutest fungiform colorless bristles. Legs and prolegs concolorous. 

 Spiracles testaceous. Length, 25 ram. ; breadth of head, 2.75 mm. From blown speci- 

 mens. 



Chrysalis. Uniform pale castaneous, glistening, with no bloom, the apical third of 

 the wing cases more or less blotched or discolored with fuliginous tints; rim of the 

 prothoracic spiracle black; cremaster very dark castaneous above, apically blackish 

 fuscous, the hooks luteo-castaneous ; hairs of body rather abundant, long and pale 

 fulvous. Length, 14 mm. ; breadth, 4 mm. From dried specimens. 



This butterfly inhabits all our southern states as far north as West Vir- 

 ginia and ^Maryland on the Atlantic coast, and west to Kansas and New 

 Mexico. 



Nothing is known of its seasons, excepting what I can give from notes 

 furnished by Dr. WilHam AVittfeld of Brevard Co., Florida. He ob- 

 tained eggs on pigweed, presumably Chenopodium, July 25 ; these hatched 

 in four days and the successive moidts were passed August 2, 5, 8, 13, and 

 the chrysalis was formed August 22, the duration of which is not staled. 

 Evidently, then, there must be several broods a year. The eggs, according 

 to Dr. Wittfeld, are always laid on the upper side of leaves ; when irri- 

 tated or in self defence, the full grown caterpillar ejects a greenish fluid 

 from its mouth. The buttei-fly flies low and almost always in the woods, 

 though it feeds at the edges of the same ; excepting this, it is seldom to be 

 found in open ground ; it feeds or suns itself, alike on a leaf or on the 

 ground, with spread wings. 



TRIBE PAMPHILIDI. 



OARISMA SCUDDER. 



Oarisma* Scudd., Syst. rev. Amer. butt., 54 (1872). Thymelicus pars Auctorum. 



Imago. Head broad, exceptionally depressed. Front transverse, three times as 

 broad as high, slightly, broadly and roundly emarginate below, the lower outer angles 

 strongly excised, slightly and uniformly tumid, surpassing considerably the front of the 

 eyes. Whole vertex raised above the eyes, though flat, the eyes being set low. An- 

 tennae in slight depressions, very distant, being separated by four times the diameter 

 of the basal joints, very short, being scarcely half as long as the elongated abdomen, 

 and hardly more than a third as long as the fore wings, composed of about thirty-one
