THE CANADIAN ENTOMOLOGIST. 303 



Gluphisia septentrionalis, Walker. 

 Dasvchira clandestina, Walker. 



Both these names refer to G. trilineata, Pack., and both antedate it. 

 Mr. Butler has sent me a sketch of septentrionalis and notes on it, and 

 Mr. J. A. Moffat has compared the type of clandestina with specimens of 

 trilineata, and writes me that " it is, so far as I can make out, almost 

 identical with what we have under the name of Gluphisia trilineata." 

 The synonymy will be : — 



G. septentrionalis, Walker. 



1855, Walker, Cat. Brit. Mus., IV., 1038, Gluphisia ? 



1882, Grote,' check list, p. 18, pr. syn. trilineata ? 



clandestina, Walker. 



1861, Walker, Can. Nat. & Geol., VI., 36, Dasychira. 



1877, Grote, Can. Ent, IX., 21, Gluphisia. 



trilineata, Packard. 



1864, Packard, Proc. Ent. Soc. Phil., III., 355. 



Ichthvura apicalis, Walker. 



As suggested by Dr. Packard (Ent. News, IV., 79), this species proves 

 to be /. vau. Mr. Butler has sent me a coloured figure of it. The name 

 takes precedence, and we have : — 



I. apicalis, Walker. 



1855, Walker, Cat. Brit. Mus., V., 1058. 



vau, Fitch. 



1859, Fitch, 5th Rept. Nox. Ins. N. Y., 65. 



indentata, Packard. 



1864, Pack., Proc. Ent. Soc. Phil, III., 352. 



oruata, Grote and Robinson. 



1868, G. and R., Trans. Am. Ent. Soc, II., 191. 



incarcerata, Boisduval. 



1868, Boisd., Am. Soc. Ent. Belg., XIL, 86. 

 Not to mention the synonymy of the paler form. 



Certila flexuosa, Walker., 



I have shown Mr. Butler's figure of this to Prof. J. B. Smith, and he 

 feels sure that it represents Raphiaf rater. This removes the name from 

 the list of undetermined Bombyces. 



Mr. Butler deserves hearty thanks for his kindness in assisting us to 

 determine these names.
