our New Check List and placed next to icarioidcs in the genus Plcbcius 

 L. ; it is possibly a lowland race of this species characterized by brown 

 ground color and heavy spotting on the underside and it is quite within 

 the bounds of probability that maricof^a Reak. will, after all, take 

 precedence over the name pardalis as the large black spots are distinctly 

 mentioned in the original description. Our San Francisco collectors 

 should be able to solve this problem and discover whether the $ "s 

 ever show any traces of blue or are constantly dark brown.

We were incorrect in stating that ohakensis falls to ciiicira Staud. ; 

 Sir Geo. Hampson has called our attention to the fact that while 

 cincrea was diagnosed in 1861 (Stett. Ent. Zeitsch. p. 369) it was not 

 until 1871 (Cat. Pal. Lep. p. 114) that the name cincrea was actually 

 given to the Labrador form and that therefore okakensis Pack, has 

 several years priority. 



Page 164. Homohadena inconstans Grt. 



Our statement that Grote originally referred this species to 

 Oncocnemis was erroneous; it was described as a Homohadena (Can. 

 Ent. XV, 28). This will not, however, aiJect the statements made in 

 the remainder of our note.

On reviewing Packard's description of quadrilineata with a view 

 to determining a White Mt. species captured by ourselves in 1916 at 

 Bretton Woods, N. H., we were struck by the fact that the description 

 did not tally well with the specimen we had recently compared with 

 the type in the Cambridge Museum Collection and on the strength of 

 which we had made pcrsimilis Hist, a synonym ; this was particularly 

 the case with regard to the underside which calls for a 'dark scalloped 

 line common to both wings and situated half-way between the discal 

 dot and outer edge.' We wrote Mr. Swett on the subject and he was 

 kind enough to examine the types ; he wrote us that of the original type 

 series only 1 $ from Orono, Me., and 1 $ from Brunswick, Me., 

 remain in the Packard Collection and that these represent two species, 

 the former showing the irregular dark s. t. line on the underside, the
