brown spot on the basal third of inner margin divided by a short white hne ; an 

 oblique line from basal third of costa to outer fourth of inner margin limits the pale 

 basal space and is darkly shaded without. Transverse posterior line brown, slender, 

 excurved beyond the end of the cell, not waved, joining the oblique line above inner 

 margin; subterminal line white, slender, excurved and parallel to the t.-p. line, not 

 waved, followed at apex by two black spots, the lower of which may have at its tip a 

 semi-hyaline white spot joined to the t.-p. line by a slender white line. Terminal 

 space lightly brown shaded. Hind wing pale brownish with mesial whitish line and 

 brown marks on the inner margin. Expanse 37 to 40 mm. 



Three males, Guadalajara, Mexico (Neumoegen), Nogales, Arizona 

 (Oslar). 



Type. — No. 7727, U. S. National Museum. 



Near Apatelodes diffidens Druce but the transverse posterior line is 

 distinct and continuous. 



Family LIMACODID^. 

 Adoneta bicaudata, new species. 



I have been keeping Adoneta leiicosigma Packard separate from 

 spinuloides Herrich-Schaeffer on the strength of a light colored speci- 

 men in the National Museum. The recent receipt of more specimens 

 of the light form, makes certain that it is specifically distinct, but also 

 that Packard's description cannot apply to it. I therefore refer leiico- 

 sigma as a synonym of spinuloides and describe the light from under 

 the name bicaudata. 



It is of a light ochraceous color, the fore wings narrowly and diffusely margined 

 with cinnamon brown. In some, this color is lightly overspread on theocherous part 

 and there is a faint median shade of the dark color. Markings as in spinuloides : a 

 black discal dot more or less obscured ; a silvery streak on costa and inner margin 

 joined by an excurved row of blackish spots. 



Described from 8 specimens, Washington, D. C. (?), marked 

 "344, October 7, 1883, issued July 16, 1884," Plummer's Island, 

 Maryland (E. A. Schwarz), Tryon, North Carolina (W. F. Fiske). 



Type. — No. 7728, U. S. National Museum. 



A blown larva is before me, marked "344," and it is the larva 

 tentatively identified as Monoleuca semifascia by me five years ago.* 



Larva. Long, rather narrow, quadrate, a little tapering behind. Dorsum 

 broad, flat, not arched and scarcely higher at joint 5, yet a little so. Subdorsal ridge 

 indicated by change in direction. Sides perpendicular or nearly so, the lateral space 

 broad, continuous with the subventral space which is infolded in the middle. Sub- 

 dorsal horns distinct, short, those of joints 3, 4, 5 and 12 moderate, those of joint 13 

 long, nearly three times as long as the ones on joint 12, the rest short, those of joints
