NYMPHALIDAE: SATVRINAE. 1785 



mesonotum, narrow, excavateil at sides, ending in two sharp, divergent projections, 

 the depression Ijetween angular; mesonotum prominent, carinated, angular, the sum- 

 mit rounded ; followed by a shallow depression ; wing cases flaring on dorsal side ; 

 color of abdomen and dorsum from bufl" larva sordid yellow-bufl", the wing and anten- 

 nae cases and the projections all more yellow; the surface finely streaked bi-own, 

 irregularly and mostly longitudinally; from posterior base of mesonotum to ninth 

 abdominal segment a brown band; the wing case shows an irregular, wavy, brown 

 stripe on disk, and a stripe on costal margin; each nervule ending in a blackish dot. 

 Length, 11.7-13.25 mm. ; greatest breadth on abdomen, 3.(j mm. 



From green larvae green chrysalids ; blue-tinted, the dorsum and abdomen streaked 

 with whitish ; wing cases without stripe ; the dorsal edges of wing cases carmine, and 

 top of head case cream color. Duration of this stage, in May, eight days. 



The butterfly is found throughout the southern states, from the southern 

 part of West Virginia and Illinois to Florida and Texas, and extends also 

 into Mexico (Monterey, Aaron) and Guatemala (Polochie valley, Butler). 

 It seems to be restricted to the vicinity of running water, so that though 

 the caterpillars seem to feed readily on almost any grasses, their natural 

 food is probably some species found only near streams. 



According to Edwards it is triple brooded in West Virginia, flying in 

 April and May, in June and July, and from about August 20 to the end 

 of September, the winter being passed in the caterpillar state when full 

 grown. Eggs laid in April hatch in six days, in August in three or four 

 days, and in October six days. According to Edwards, the caterpillar 

 has but four stages, which are passed in from twenty-five to thirty or more 

 days, according to the season, and the chrysalis hangs eight days in May. 

 The caterpillar rests with the face upon the ground, so as to throw its 

 horns forward in a reverse position to those of the tail. 



NEONYMPHA MITCHELLII. 



Neonympha mitchellii French, Can. ent., xxi : 2.5-27 (1889). 



Imago. Head covered with mingled gray, black and brown hairs, paler in a stripe 

 behind the eyes, and on the sides of the palpi; antennae honey yellow at tip, else- 

 where brown, with white patches at the base of each joint. Thorax with legs above 

 and below uniform mouse-brown. 



Wings above uniform mouse-brown without markings, excepting a slightly darker 

 edging to the outer border of the wings, on the hind wings preceded by a slightly 

 paler line. Beneath, the same with a grayish sutTusion caused by a profuse flecking of 

 clay brown scales. Fore wings traversed by four narrow, ochre-yellow stripes, the 

 inner nearly straight, crossing the outer half of the cell, the outer just withiu the 

 outer m.argin, the other two arcuate in opposite senses and meeting above, enclosing a 

 very large oval space, nearly one-third the size of the wing, and including in the 

 "middle, in the median and lower subcostal interspaces, a transverse series of four or 

 five round or roundish ocelli, the middle ones largest, nearly fllling the interspaces, 

 composed of an outer rim of pale yellow scales surrounding a blackish purple spot, 

 with a few metallic blue scales scattered through it. Hind xuinrjs with similar trans- 

 verse stripes, the middle ones enclosing a longer oval, in which are six ocelli, situated 

 In all the median and subcostal interspaces, larger than on the fore wings, but as there 

 the middle ones largest, in this case three in number; especially the yellow edging is 

 broader and the metallic flecking of the interior more distinct. Expanse of wings
