334 FIRST ANNUAL REPORT OF THE STATE ENTOMOLOGIST. 



none of the bluish hairs which sprinkle the primaries of iV. funeralis and are 

 still more numerous in N. Juvenalis Fabr. and N. 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. Propertius Scudd.-Burg., 

 resembling it in the quite oblique line of subsagittate black spots crossing the 

 nervules. The black markings of the wings are more strongly contrasted with 

 the dark brown ground than in N. funeralis or N. Ncevins, 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 N. 

 Juvenalis ; 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. Jwoenalis^ 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 conspicuously 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 m cell 

 9 is wanting. 



Expanse of wings: $ , 1.90 to 2 in. ; ? ? , 1.80 in. 

 Described from 4 ^ 's and 1 ? , from Indian River, Florida. 



This is the largest species known to us in the genus. It is separable from N. 

 Jutenalis and N. Propertius by its darker color, less distinct ornamentation, less 

 rounded wings, and absence of the white spots of secondaries in cells 6 and 7. 

 From N. Ncevius with which it is associated, it is distinguished by its large size, 

 more distinct markings, and the contrasting lighter shade of the palpi. 



The genitalia of this species resemble those given for N. Horatius and J^. Vir. 

 gilius, named from their genital armature, by Scudder and Burgess, but I am un- 

 able to refer it to either. Examples from Florida, which Mr. Scudder has 

 kindly permitted me to examine, and labeled by him as iV. Horati^is^ have the 

 white hyaline spots of the primaries larger than in the above species, and, ac- 



* In 45 examples of N. Juvenalis before me, these white spots are a prominent feature. 

 In one example the spots each occupy the entire breadth of the cell.
