DESCRTPTioy OF Xew Species of Xisoxiades. 167 



of the nervules and extending on the cilia. The cilia are of the color 

 of the gronnd of the wings, with a few of the basilar scales gray. 



Posterior wings above, of a darker ground than the anterior, sprink- 

 led with blackish scales, darker basally, and with pale yellow-brown 

 spots, of wliich the discal spot (conspicuous in JST. Persius ? ), is 

 obsolete ; the spots of the submarginal row are crescentic in form ; 

 those of the marginal row are obsolete ; between these two series, and 

 nearly inclosed by them, is a range of oval fuscous spots, and anterior 

 to the submarginal row is a similar range of sub-connected spots. Cilia 

 light brown, with dark brown basilar scales. 



Beneath (Plate 7, tig. 12), reddish-brown with the terminal margin 

 t^ray. The anterior wings have the fuscous sj)ots of the submarginal 

 Dand and marginal row as on the upper surface ; of the discal band, the 

 cellular spots are alone obscurely visible ; the basal ones are lost in the 

 color of the ground ; the marginal interspaceal brown spots below 

 the subcostal nerv^ules rest centrally on elliptical gray patches, while 

 those of the posterior wings approach a semi-oval form, and are pre- 

 ceded by conspicuous gray crescents which nearly inclose them by 

 uniting with some marginal gray scales ; at the tips of these crescents, 

 a submarginal row of fuscous spots is obscurely seen ; the discal 

 spots, so distinct on the secondaries of xY. Martialis, are here obsolete. 

 Cilia of the wings, reddish brown ; those of the anteriors are somewhat 

 encroached upon by the gray of the margin. 



Expanse of wings 1.06 of an inch. Length of body, .45 of an inch. 



This interesting species was taken at Center on the 12th of May, 

 1871.* It may be known by its small size, being the smallest yet dis- 

 covered of the genus ; by the entire absence of the usual white apical 

 spots pertaining to all the other known species except JSl'. Brizo / by 

 the quite curved submarginal band of elongate black dashes ; by the 

 peculiar cellular spot and the brown scales covering the discal cross- 

 vein. In its markings it approaches N. Martialis more nearly than 

 any other of our species. 



Only a single individual was obtained. The time of its appearance 

 another season will be awaited with no little anxiety, in the hope that 

 it will prove another instance of a solitary capture being the precursor 

 of many others the ensuing year. Thus, it had excited much surprise 



* If an apology is due for embodying in a " report for 1869 " a few observations 

 made during the two following years, it may be found in the temptation to 

 embrace the earliest favorable opportunity for publication, in consideration of the 

 unavoidable delays which sometimes occur in the issue of the State Cabinet reports, 

 as in the case of the present one, which, when nearly all in type and within, perhaps, 

 two weeks of its completion, was destroyed by fire, in the burning of Weed, Parsons 

 & Co.'s printing house in April of the present year (1871).
