324 GROTE AND ROBINSON. 



the black scales are followefl by a fulvous streak, tliis by first a few 

 white then black scales. Outside of the black scales, edging the sub- 

 terminal line on the next interspace above, is a patch of powdery blue 

 scales extending to the margin; on tlu; interspace above is a distinct 

 fulvous crescent, succeeded by black scales on the margin ; the fulvous 

 scales are also faintly continued on the next succeeding interspace, 

 within the subterminal lunule, which is here completely enclosed. A 

 narrow white line lies directly before the margin ; its analogue on the 

 primaries is faintly perceptible at internal angle. A narrow, dark, ter- 

 minal shade; fringes as on primaries.

The absolute distinguishing character of this species from T. lorata, 

 its nearest ally, consists in the absence of the extra basal line of dark 

 atoms which crosses both wings beneath in the species from Virginia. 

 A female specimen (Ga.!) differs by the costal edge of primaries at base 

 and the extremity of the antennal club beneath being fulvous. 



Since describing T. lorata, we have seen the typical specimen of 

 Godart's T. falacer, in the Colleotion of Dr. Boisduval in Paris. It 

 is a specimen of T. calauus. and is so regarded by Dr. Boisduval. The 

 species figured by LeConte was not known in nature to Dr. Boisduval, 

 who was led to regard these figures as representing Godart's spGcie^. 

 Under the name of T. falacer Dr. Harris has probably described 

 specimens of T. calanus. From this latter species T. inorata differs 

 by its smaller size, its more blackish color, darker fringes, and the ab- 

 sence of the orange lunule on the upper surface of secondaries before 

 anal angle. 



The synonymy of these closely allied species will then be as follows; 

 1. 1'. calanus, }Y(Mitu\ (Rii.^ticns annatus Calanus, Iliibn.; Tkcvla. J'a- 

 laccr, Godt.; /(/. Bdv. k Lcc, p. text). 2. Thecla inorata, G. k li. 

 ( rha-la falacer, % Bdv. k Lee, Plate 29). 3. Thecla lorata, G. A- R. 

 4. Thecla acadica, Edwds. In this latter species the extra discal band 

 of the under surface of primaries is completely macular, and the gene- 

 ral color is more as in Thecla mellinus, Wadw. (^T. ]iumuli,\l\iYv\^). 

 In all these species the costal edge of primaries at base is more or less 

 touched with fulvous, most prominently so in T. calanus, while in T. 

 lorata it is with difficulty to be detected.
