AMERICAN LEPIDOPTERA. 17 



margin, nervules darker clothed; a pale streak within anal angle, mar- 

 gined without by a very few roseate scales, and discontinued above 

 median nervure. Fringes a very little paler than ou anterior wings. 

 Undersurface of wings, silky, cinereous, with a faint purplish lustre, 

 darkest superiorly, and with a median faint pale shade line across both 

 pair, arcuated on anterior wings where it is analogous with the post-me- 

 dian line of the upper surface. 



E.rpaiisr, 0.75 inches. Length of hodi/, 0.35 inches. 



Habitat. — Atlantic District. (Ma.^s. to Pa. I) 



Mr. Walker's description makes no mention of the abbreviated band 

 on the upper surface of posterior wings; the anal tuft is not " whitish." 

 nor are the fringes of the secondaries properly characterized as of the 

 same hue. The hind wings are rather dark cinereous, not " reneous," 

 or concolorous with the fringes of the primaries. Nevertheless, the 

 general coloration and the conformation of the distinct lines of the 

 upper surface of anterior wings, lead us to believe, that this is the spe- 

 cies intended in the British Museum Lists. In the case that a new 

 name be used for this species, we propose that of Botys (Rhodaria) 

 vinulenta, nob. Athaloessa signatalis, Zcller., sp., had been already 

 described at the time of the publication of Rhodaria signatalis, 

 Walker. 



A single specimen, brought by Mr. Ridings from Colorado Territory, 

 oiFers no points of distinction, when compared with specimens of B. 

 signatalis, from the Atlantic States. 



Botys laticlavia, n. sp. (Plate 2, fig. 12, -J, .) 

 Bhodana laticlavia, G. & R., MS. 



Malt and Female. — Head, above, and palpi obscure ochreous fuscous; 

 two narrow, white lines run from the tips of the palpi, along their su- 

 perior edge, back to the antennal bases, narrowly margining the eyes 

 on the front; beneath, the palpi are white at base. Thorax, ochreous; 

 abdomen, pale dull ochraceous, the segments obsoletely defined by a 

 paler edging of scales posteriorly ; beneath, the legs and under corpo- 

 ral surface are of a dull pale color, not whitish, but of an obscure 

 ochraceous or cinereous hue. Antennae, dark, somewhat purplish su- 

 periorly. 



Anterior wings, light purple, silky; a broad, rather square, yellow 

 patch at base, resting on internal margin, but not attaining the costal 

 region; a distinct, sub-spherical, yellow discal spot; a broad, yellow, 

 slightly oblique, sub-terminal band, a little narrower and constricted in 

 the female, running from internal margin to costal region, not attain-
