THE CANADIAN ENTOMOLOGIST. 45 



J>. 92, and re-described by Dr. Clemens, Proc. Ent. Soc. P/ii/a., 1863, p. 

 216. It does not agree accurately with either of Dr. Clemens' 

 descriptions, but it seems to be a somewhat variable species, though some 

 of the most striking marks in my three specimens are not mentioned by 

 Dr. Clemens. I therefore retain the above name for the present, at least,_ 

 as Dr. Clemens gives no measurement for his species, and was unacquainted 

 with its food plant. In the following description I have noted the points 

 in which my specimens differ among themselves and from Dr. Clemens 

 ■description. 



Maxillary palpi and basal joint of the labial palpi dark brown ; ter- 

 minal joint white, with a dark brown annulus before the middle. (In one 

 specimen the labial palpi are entirely white, except the annulus. Dr. 

 Clemens' first description says : " white, with a blackish spot near the 

 middle and one near the tip." His second says : " Second joint fuscous 

 at its end, third with a broad fuscous ring.'') Antennae brown ; head 

 white ; thorax white, narrowly margined near the apex with dark brown, 

 and a dark brown line beginning on the head and extending to the apex 

 of the thorax. (Dr. Clemens does not mention this line nor the dark 

 margins.) Primaries dark grayish brown. A white streak along the 

 dorsal margin from the base to about the middle, where it is confluent 

 with the first dorsal oblique streak. (In one specimen it does not attain 

 the oblique streak. This oblique streak is not mentioned by Clemens, 

 who simply says " the basal portion of the inner margin is white.'') A 

 small white dorsal streak at the beginning of the ciliae (not mentioned by 

 Clemens.) A short white costal streak in the basal portion of the wing; 

 another about the middle, extending to or crossing the fold and pointing 

 towards the second dorsal streak. (Dr. Clemens calls this second costal 

 streak a fascia extending obliquely across the wings and sometimes con- 

 stricted or partially interrupted near the dorsal margin. If sufficiently 

 interrupted, this would make my second d6rsal streak.) Two narrow 

 white fasciae in the apical part of the wing, the last one not oblique. (Dr. 

 Clemens calls these costal streaks extended to the middle.) All these 

 streaks are dark margined internally, and the two last named are continued 

 into the dorsal ciliae (a mark not mentioned by Clemens.) A fifth white 

 , short costal streak at the apex (not mentioned by Clemens, unless this is 

 what he means by " Ciliae — at the tip of the wings white, touched with 

 black at the ends.") Ciliae of the general hue, with a dark brown hinder 

 marginal line beyond their middle. Anterior legs dark brown, with yel-
