46 THE LEPIDOPTERIST 



below. Secondaries deep pink also without any 

 markings, except black discal dots which are on all 

 wings. Fringe whitish, slightly checkered. This is 

 very closely allied to boreata Pack, described in the 

 Proc. of the Peabody Academy of Sciences, taken 

 on Mt. Washington, N- H. Boreata Packard has 

 priority over alpmata Packard, described on the 

 same page, the differences being merely sexual. 



Dyar placed boreata and alpinata Packard as syno- 

 nyms of the European paludata, but Barnes and Mc- 

 Dunnough in their recent check list give it racial rank 

 and correctly so, I believe from the description that 

 lahr-adoriensis Som. is the same as boreata Packard, 

 but the latter type in the Boston Society of Natural 

 History is not fresh and it is hard to ban conclusions 

 on one specimen- I have quite a series of labrado- 

 riensis from Roma, Labrador, before me and there 

 seems to be very little variation. Thaxteri has a pink 

 head, where the Labrador form has a gray one, and 

 the color of primaries also separates them. I think 

 from the genitalia, it should be listed as distinct from 

 paludata. The European paludata lacks the long sac- 

 culus of the Labrador and New Foundland forms 

 and the shape of the outer margin of costa is very 

 distinct. In the American form the outer margin of 

 costa has a deep excision, forming a kind of jaw, as 

 it were. I can hardly see how any of the Labrador 

 or New Foundland forms can be regarded as palu- 

 data, the valvae being of a different shape. The penis 

 is very long but rather bulbous, at base the simial 

 duct seems to have minute armature close to sedoca- 

 gus. I think that boreata Packard will prove to be 

 same as l-abradoriensis. Som-, the former having 

 priority and thaxteri being a race of it. I take pleas- 

 ure in naming this pretty form after Professor Ro- 

 land Thaxter, whose collection forms an important 

 part of the Museum collection.
