1090 THE I5UTTERFLIES OF NEW ENGLAND. 



on tlie under surface, where they are pale. Surface of the body finely punctate. 

 Spiracle.s of the color of the stigmatal band. Legs and prolegs of tlie color of the 

 under surface, the claws scarcely infuscated. Length, 18 mm. ; breadth of head, 

 1.8 mm. ; breadth of body, 2.5 mm. 



Chrysalis (84:56). Translucent green, the upper half with a bluish tinge, which 

 sometimes is wanting on the outer sides of the abdominal segments, and sometimes 

 encroaches more or less upon the whole of the under surface, where, however, it is 

 never so distinct as above; the frontal tubercle varying from pallid to fuliginous, 

 generally considerably darker below than above; lateral carina of the wings often 

 more or less pallid, sometimes rendered more distinct by a slightly darker edging 

 above; basal wing tubercle marked by pallid or ivory white, frequently intensified by 

 being in an infumated blotch. Surface of body generally smooth, but the entire sur- 

 face of the wings and of the head vermiculate, the creases often more or less infus- 

 cated, but generally to a very slight extent. The body in general may appear almost 

 destitute of any markings, but even the clearest specimens show a lateral series of 

 black dots just in advance of the middle of the third to the eighth abdominal seg- 

 ments, and a sprinkling of even finer black dots all over the ventral surface of the 

 abdomen and the outermost portions of the dorsal surface; but generally the mark- 

 ings are much heavier, the dots of the lateral scries become double and sometimes 

 onflueut, and extend even as far as the mesothorax. The prothorax is dotted on the 

 anterior half away from the middle with blackish fuscous specks, and there is besides 

 a series of laterodorsal spots on all the thoracic and abdominal segments, the abdomi- 

 nal segments, at least on the front half of the abdomen, including three spots, the ante- 

 rior the innermost. Besides this there is often seen a fuliginous blotch on a pallid 

 ground, just in advance of and above the spiracle of the fourth abdominal segment; 

 black dots follow the outer margin of the wing, in each of tlie interspaces, with 

 series of dots round the nervures, at tolerably regular intervals; at the same time the 

 sprinkling of black dots upon the ventral segments may considerably increase and ex- 

 tend upon the dorsal surface to a much greater extent than in tlie clearest specimens; 

 a fuliginous dorsal line, including a mediodorsal, pallid thread, often follows the 

 thoracic segments, and the head is marked at its extreme base, dorsally, with fuliginous 

 spots. The girth crosses the middle of the first abdominal segment. Length of body, 

 15.5 mm. ; greatest height at the wing cases, 4.5 mm. ; width, 3.4 mm. 



Geographical distribution (26: 2). This little butterfly is a char- 

 acteristic memlier of tiie Carolinian fauna where it is very abundant. It is 

 found from the Atlantic to the Great Plains in Iowa and Kansas, and south 

 of the loftier Kocky Mountains extends through Arizona to the Pacific Ocean 

 next the boundary line between California and Mexico. To the south it 

 occurs to the very limits of our territoiy from Atlantic to Pacific, having 

 been found at Florida Keys (Burgess, Palmer, Maynard), southern Texas 

 (Aaron, Lintner) and extreme southern California (H. Edwards). It 

 extends even beyond this, to Cuba (Gundlach) and also, according to 

 this writer, to Jamaica and Porto Rico. On the continent itself it extends 

 through Mexico, Rio Verte (Palmer) to Honduras (Reakirt). It is one 

 of the exceedingly few butterflies found at Bermuda (Jones). It has been 

 reported from Missouri (Museum Comparative Zoology), Kansas (Snow), 

 Illinois (Riley, Doubleday, INIichigan University). It extends beyond the 

 northern limit of the Carolinian fauna, having been found in Wisconsin 

 as far north as Racine where it is common (Hoy), in central Iowa at 

 Ames (Osborn), at Rockport "among the most rare species" (Kirtland)
