34 TWENTY-THIRD REPORT ON THE STATE CABINET. [166] 



single individual of it was taken by me last season, in Bethlehem, on 

 the 30th of July. The Schoharie specimens, as they appear in my 

 collection, differ from this, in being less shaded with red ; but it is 

 probable that their colors have become somewhat impaired, through a 

 partial exposure to the light during my earlier collections. The colors, 

 as above given, are from the perfectly fresh Bethlehem specimen.* 



Nisoniades Ausonius nov. sp. Plate 7, figs. 11, 12, $ . 



Head, palpi, thorax and abdomen reddish-brown ; the latter with a 

 few grayish scales at the margins of the segments, and with yellow- 

 brown hairs bordering the genital organs, less conspicuously so than in 

 N. Martialis / antennae red at tip, annulated with a clearer white than 

 in the other species, having the joints beneath almost entirely white. 



Anterior wings above, pale umber-brown with grayish scales 

 sprinkled over most of their surface (more diffused than in the other 

 species) except on the fuscous bands, showing especially behind the sub- 

 marginal band. There are two brown basilar spots resting on the 

 subcostal and median nervures, not so dark as those of the disc. The 

 discal band usually continuous in this genus, here consists of three 

 elongate fuscous dashes (appearing to the unaided eye as a single spot) 

 resting on the subcostal near the discal cross-vein, extending nearly 

 half-way to the median, the intervening space having merely an indica 

 tion of the spot which appears distinctly in most of the species as the 

 inner cellular tooth of the discal band ; following this is an obscure 

 fuscous spot at the fork of the first and second median nervules, and 

 beyond, the usual hour-glass shaped spot extending from the second me 

 dian nervule to the submedian with its constriction on the interspaceal 

 fold. The discal cross-vein is quite curved and is conspicuously marked 

 in brown. The submarginal band of fuscous spots is doubly curved, 

 being convex toward the hind margin, from the costa to the third 

 median nervule, thence concave to its termination at the submedian. It 

 consists of four acutely ellipsoidal fuscous spots between the subcostal 

 nervules, which are wholly destitute of the usual hyaline spots, followed 

 by three others of similar form but of greater breadth, the next suba- 

 cute posteriorly, and the last, similar in outline to the corresponding 

 one of the discal band. There is a marginal row of interspaceal brown 

 spots, the first four of which are surrounded with gray scales and lie 

 near the margin, and the remaining four more remote from it than in 

 JV. Martialis j also, an obscure row of brown spots resting on the tips 



* The delay in the publication of this report has permitted a revision of the 

 description of this species, from the inspection of thirty specimens subsequently 

 collected, and of a few reared from the larvae. Notes upon the earlier stages of the 

 insect (egg, larva and chrysalis) have been made, and will be given in a future paper.
