AMERICAN LEPIDOPTERA. 189 



This is an aberrant form, but seems to find its position here much 

 more naturally than in Anarta. The specimen examined by Mr. Grote 

 (1. c.) is no longer in our possession ; it was communicated by Mr. W. 

 H. Edwards and immediately returned after determination. This is a 

 high arctic species; the localities hitherto accorded it are as follows: 

 '•St. Martin's Falls. Albany River, Hudson's Bay," — Dr. Barnston — 

 "Fort Confidence," Sir J. Richardson — W(t/ker, 1. c. ; "Youkon Riv- 

 er, mouth of Porcupine River," R. Kennicott — Grofe, \. c; "Fort 

 Resolution am Sklaven-see (Great Slave Lake) westlich von der Hud- 

 son's Bay unter dem 61° N. Br.," Baron Osten Sacken — Zdlcr, 1. c.

This is a typical form ; the species is allied to the European A. par- 

 thenias and A. notha. Harris' MS. name does not appear to have 

 been published. 



Habitat. — Labrador southward through the Eastern States. 



DRASTERIA, Hiibner. 

 Drasteria agricola. n. s. (Plate 4, fig. 34, 9 •) 



Umber brown. Head and thorax, above, obscure brown mixed with 

 ashen scales, especially on the tegulae. Abdomen, obscure testaceous 

 cinereous. Primaries, above, of an even umber-brown, varying in the 

 depth of color and distinctness of the ornamentation. A transverse, 

 anterior, oblique pale line, edged within by brown scales, leaves the 

 costa at basal fourth and runs obliquely downwards to internal margin 

 (which it reaches at about the middle) is here shortly continued, thence 

 arises, forming a sinus, and is apparently continued till below the me- 

 dian nervure, where it joins the transverse anterior line, forming thus 

 a second sinus inversed when compared with the first. The transverse 

 posterior line is dark, edged outwardly by pale scales,* evenly and 

 finely dentate or tremulous, projected slightly outwardly below the 

 costa, and descending straightly and no further than the submedian 

 nervure. At this point it runs inwardly backward up the wing, meet- 

 ing and becoming continuous with the transverse anterior line with 

 which it is concolorous. Thus these two lines form a rude figure of 

 an inversed M with rounded angles, of which the inner limb or first 

 sinus is broadest and longest, since it reaches the internal margin, 



* This pale edging is obliterate in most of the individuals before us ; we have 

 taken the strongest marked specimen for the type of the species.
