206 THE BUTTERFLIES OF NEW ENGLAND. 



direction, while tlie larger diameter of others, rarely exceeding one and a half times 

 the shorter, may lie in any direction ; all are more or less angular, Init all the angles 

 are more or less rounded ; the depressions are shallow and wholly smooth, the cell 

 walls low and rounded. The diameter of the egg is a1)out a millimetre and its color 

 pale green. 



Caterpillar. First stage (70:11). Head (78:15) luteo-testaceous, the surface 

 broadly reticulate with faint lines but otherwise smooth. Body delicate green, after- 

 wards changing to decided green, with longitudinal whitish stripes on either side of the 

 dorsal line and along the lateral and stigrnatal lines ; legs and prolegs green ; scattered 

 hairs Avhite ; ranged clubbed hairs black, not a third as long as the tapering hairs of 

 the head, except on the last segments where they are half as long again as the head 

 hairs. Length, 3 mm. ; breadth of head, .7 mm. (Principally after Edwards.) 



Seco7id stage. Head red-brown, Avith two green patches on either side the suture in 

 front; frontal triangle and back of head deep green, the ocelli emerald green; some- 

 times the head is wholly green and the coronal tubercles reddish; or a horizontal 

 broAvn band may traverse the front. Body green, the caudal fork faintly red; the 

 mimerous, fine, bristle-bearing papillae of the same color, excepting in yellowish, longi- 

 tudinal stripes as at the preceding stage ; under surface, legs and prolegs green. Length, 

 6 mm. The following stages are very similar. (After Edwards.) 



Last stage (74 : 8,12). Head (78 : 16) pea-green, the coronal projections, except their 

 base, testaceous, the moutli parts and lower edge of triangle pale testaceous; papillae 

 pale green with pale or black tine hairs, interspersed sparsely but uniformly with simi- 

 lar white papillae; ocelli emerald green in brown rings. Body yellow green, the 

 numerous papillae of the body color except in the longitudinal stripes, where they have 

 a more distinct serial arrangement, and are yellow, forming slender, yellowish, longitu- 

 dinal stripes, viz., a subdorsal stripe adjoining a dorsal stripe of a deeper green than 

 usual ; a lateral extending to the tips of the caudal fork, a ventrostigmatal, and l)etween 

 the last two a pair of less distinct or more ditt'used stripes ; caudal fork reddish ; under 

 surface with legs and prolegs green ; spiracles buff. Length, 30 mm. (From blown 

 specimens and Edwards' description.) 



Chrysalis (83 : 10,11). Green, all the carinate portions cream color, the Aviug cases 

 closely irrorate with the same. Surface of body, excepting the head, with delicate, 

 irregularly longitudinal, transversely and very finely striate, embossed vermiculations 

 paler than the ground. Length, 12 mm. ; breadth of head, 2.5 mm. ; of tliorax and 

 abdomen, at most, 5 mm. (From dried specimens and Edwards' description.) 



Distribution (18:7). This butterfly is strictly a southern species, 

 and would not be introduced in this part of this work, had not Mr. Ed- 

 wards received specimens taken at Morristown, N. J., rendering it not 

 altogether unlikely that it may yet occasionally be found on Long Island. 

 The only other localities from which it is recorded are Atlantic City, 

 N. J., where it was sufficiently common not to be an accidental visitor 

 (Aaron), along the creeks in the mountain valleys by the boundary of 

 North Carolina and Tennessee "common" (Aaron), Alabama (Gosse), 

 Georgia (Abbot), Appalachicola (Chapman) and Indian River, Fla. 

 (Wittfeld), and Texas (Strecker). 



Food plant. Dr. Chapman has reared the caterpillar in Florida on 

 Panicum sanguinale Linn. Mr. Edwards had difficulty in raising it on 

 our ordinary grasses and found that by selecting one of the coarser 

 species, Dactylotenium aegyptiacum, the caterpillars fed more readily, and 

 were healthier.
