spicuous, and the pale fringe of the secondaries in one example 

 shows a tendency toward the white fringe of that species. Its 

 wings are not quite as pointed. The examples before me show 

 none of the bluish hairs which sprinkle the primaries of N. funer- 

 alis and are still more numerous in N. Juve7ialis Fabr. and A^. 

 Propertius Scudd.-Burg. 



This may possibly be the N. Terentius of Scudd.-Burg., 

 based upon the genital armature ; but as the differences presented 

 between the genitalia of this species, which have been carefully 

 observed, and those of N. Terentius as described and illustrated, 

 are greater than those which have served to separate other of the 

 genitalic species, it would not be proper to accept the two as 

 identical. 



NiSONIADES PETRONIUS, n. sp. 



In ornamentation and general character, allied to N. Proper- 

 tius Scudd.-Burg., resembling it in the quite oblique line of sub- 

 sagittate black spots crossing the nervules. The black ma kings 

 of the wings are more strongly contrasted with the dark brown 

 ground than in N. funeralis or N. Naevius, but less so than in N. 

 Propertius and N. Juvenalis — about equal to N. Persius. The 

 white hyaline spots of the primaries are of medium size — smaller 

 than in the average of A^. Jiivenalis ; that in the discal cell is 

 small ; that in cell 3 on the transverse line of sagittate spots 

 is crescentic, concave toward the base ; below the latter, in cell 2, 

 a smaller white spot, wanting in one example. 



Beneath, reddish-brown, especially the secondaries, which 

 show two rows of pale brown submarginal spots which become 

 obsolete before reaching the front margin of the wing, and wholly 

 want the white spots in cells 6 and 7 which characterize N. 

 Juvenalis * and N. Propertius. The white spots of the primaries 

 are larger than above. 



Head: above the eyes and just behind the " locklet " are a 

 few white scales ; behind and beneath the eyes are some pale 

 yellow-brown scales, and similar colored hairs compose most of 

 the palpal covering, quite in contrast with the dark brown color 

 of the legs, thorax and abdomen. 



A single ? , accompanying the examples submitted to me, I 

 refer, somewhat doubtfully to this species, from general markings 

 and the pale-colored palpi. The transverse row of ellipsoidal 

 black spots, and those of the medial and basal regions, are con- 

 spicuously outlined on a somewhat pale umber-brown ground — 

 the contrast about that presented in N. Martialis ? . An oval 

 white spot in cell 2 accompanies the round one in cell 3. The 

 costo-apical white spot in cell 9 is wanting. 



■* In 45 examples of TV. Juvenalis before me, these white spots are a prominent feat- 

 ure. In one example, the spot's each occupy the entire breadth of the cell.
