130 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



174. Thecla autolycus Edwards. 



This butterfly ranges from Missouri to Texas. The following ac- 

 count is given us by Professor Riley : 



Found May 8, 1872, under an oak tree, beneath stone and bricks, a rather curious 

 conchiliform larva. 



Larva. — Head and first joint retractile. Color dull straw-yellow, variegated with 

 pale fulvous and olive green. Minutely granulated with black spots, each giving 

 rise to a short stiff hair. Dorsum narrow, flattened ; sides sloping roof-fashion. Ven- 

 ter glaucous, with full complement of legs well developed. Stigmata large, but so 

 coucolorous with body that they are seen with difficulty. Before transforming to 

 pupa the distinctive characters are lost and it becomes pinkish, more rounded, and 

 the black dots are all pale. 



Pupa. — Of the normal rounded form ; of a dull dirty yellowish-brown, speckled with 

 black, and pubescent with short pale blunt bristles. The head is produced into a 

 hood with flattened frontal edge, and the characteristic feature is a white narrow 

 trausverse egg-like elevated spot in place of the first spiracle on suture between head 

 and thorax — looking as though they might be eyes. Head parts not distinguishable. 

 Imago issued May 25. (Unpublished notes.) 



Butterfly. — Difters from Thecla favomua in the points of the W not touching the 

 outer line. Expanse of wings, 1.05 to 1.1 inches. (French.) 



175. Thecla edwardsii Saunders. 



The following note on this butterfly, which ranges from Maine to 

 Nebraska and Colorado, has been contributed by Professor Riley : 



July 2, 1875, found two larvae of a Thecla on oak. They are dark velvety green ; 

 changed to pupa July 4, and the imago issued on the 13th. (Unpublished notes.) 



Butterfly. — Upper surface pale wood-brown ; the male with the usual subcostal sex- 

 mark, hind wings with one short tail and an angle in place of the second tail ; two 

 faint blackish spots on the hind wings, one between the tail and the angle and the 

 other towards the anal angle, with faint orange crescents before each. 



Under side paler than the upper, two rows of spots across each wing, as in the lines 

 of Thecla acadica Edwards; they are shorter, with spaces between. The spots of the 

 inner row, except the last two on the hind wings, are oblong and oval, each sur- 

 rounded with white, the last two longer than the others. The outer row is a series 

 of blackish crescents, edged on the inner side with white, on the outside with orange, 

 fading out towards the apex of the fore wings, more prominent at the anal portion 

 of the hind wings; the usual blue patch between the next to the last and the mar- 

 gin, and the two black spots of the other species. At the end of the discal cell a 

 spot similar to the spots of the inner row. Maine to Nebraska, Colorado. Expanse 

 of wings, 1.1 inches. (French.) 



176. Thecla calaiius (Huebner). 



According to Scudder (Butterflies of the Eastern United States) this 

 biitterfly feeds on Qnercus rubra and Q.falcata, but prefers the walnut 

 and hickory. (See Walnut Insects.)
