Otherwise iu good condition. This is distinctly the smallest species 

 in this series and characteristic by the almost complete absence of 

 maculation. The pectinations of the male antenuse are as in elimata. 

 The specimens were taken at sugar by Mr. J. A. Grossbeck.

Ground color bluish-ash-gray. Head more whitish, palpi black at the sides. 

 Collar with a blackish median line, inferlorly a little paler. Thoracic tuftings 

 distinct, patagia with a black line at base of wings. Primaries with the trans- 

 verse maculation obscure, except for the t. p. line, which is marked by veuular 

 pale dots, the tendency being toward a strigate type which is not, however, very 

 conspicuously developed. There is a narrow black basal streak marked by a 

 paler gray shade which extends into an outward angle of the t. a. line nearly to 

 the middle of the wing, and beyond which a narrow obscurely marked claviform 

 extends across the median space. The basal line is marked by geminate oblique 

 streaks on the costa. T. a. line broken, partly lost, with long outward teeth in 

 the interspaces, geminate, with gray included spaces. T. p. line irregularly cren- 

 ulate and denticulate, incomplete, but marked on the veins by a series of gray 

 dots, which after the abrupt outcurve on the costa, run almost parallel with the 

 outer margin. S. t. line lost, the interspaces toward the margin with diffuse 

 smoky shadings. There is a narrow pale line at the base of the gray fringes. 

 Orbicular very narrow, oblique, gray filled, open toward the costa, narrowly black 

 margined and extending to the inferior angle of the reniform,but not fused with 

 it. Secondaries rather evenly smoky, the discal lunule and median line of under, 

 side showing through. Beneath : gray, powdery, costal region of both wings 

 with a reddish tinge; a common crenulate extra-median line and a smoky discal 

 lunule.

One male, in good condition, from Prof. C. V. Piper. This spe- 

 cies has been in my collection for many years associated with the 

 female of dernarius, also now described. I could never decide 

 whether I had one species in which the sexes differed markedly or 

 whether there were two allied species, and therefore waited for addi- 

 tional material. The occuri'ence of a male dernarius has enabled 

 me to decide the question satisfactorily. The antennae are serrated 

 and bristle tufted, and the species is allied to vernilis in type of 

 maculation. As I cannot actually demonstrate any spinulation 

 of the fore-tibia, perhaps a generic reference to Anomogyna as de- 

 fined by Hampson may be better; but as in dernarius, which is 

 closely allied, there are none visible in the female, though they are 

 obvious in the somewhat defective male, I prefer to hold the species 

 here for the present, until more material will enable the question to 

 be settled.
