936 THE BUTTKRKLIES OF NEW ENGLAND. 



slightly dcpper tint of violet on the upper surface of the wings of the male 

 ncglecta ; in tiiese respects, also, as well as in sueh other slight ditlerenccs 

 as appear in comparison of the more typical examples, a complete and easy 

 transition appears hetween the two. Lucia and violacea heingbut early and 

 late meml)ers of the same brood there is also every gradation between 

 them ; but here the case is altered, for, first, there is the ditt'erence in the 

 time of appearance often not found in tlie larger and smaller summer forms, 

 and second, there is a corresponding segregation of foi'nis, and a tendency of 

 inter"-rades to resemlile closely one or the other according; to their time of 

 eclosion. Marginata on tlie otiier hand seems to me only one of the 

 stages in the intergrades between these two, possibly sliglitly more com- 

 mon than others, but not so in New England at least ; on general consider- 

 ations it should he looked for as the extremest type in the direction of lucia 

 where lucia proper does not exist ; but I do not see that we gain anything 

 here by the use of a separate name. There is, however, an exception to be 

 made in favor of the use of the subordinate term nigra for the dark dimor- 

 phic male of the race violacea. 



Distribution (24 : fi ) . This delicate little Imttcrfly is already known 

 over a vast extent of territory. As already stated, it has various forms 

 previously looked upon as adistinct species, having distinctive geographical 

 boundaries. It occurs in Alaska (Dall), lint until recently — indeed since 

 the printing of my map — has not been reported from any of the re- 

 gion between that and the lower Saskatchewan (Kirby), which is the 

 more surprising as no inconsiderable collections have been obtained from 

 there. Now we know of it from Telegraph Creek, Lat. 58°, Long. 131° 

 (Dawson) and Cassiar trail, ten miles west of Dease Lake, Lat. .58° 23' 

 N., Long. 130° 11' W. (Dawson). Otherwise its northern boundaries 

 extend to not far north of the southern extremity of Hudson Bay ; for it 

 has been taken at Lake Winnipeg (Kennicutt, Scudder), at Martin's 

 Falls, Albany River (British ^luseum), the southern coast of Labrador 

 and Anticosti (Couper). The extreme western boundaries of this north- 

 ern portion of its range are quite unknown : but it has been taken iu 

 Dakota, Montana and Ne\ada (Edwards) and is found in Victoria 

 (Fletcher). Further soutli on the Pacific coast it assumes a distinctive 

 form, formerly considered another species (piasus) . Here it has been found 

 from the southern boundaiy of California and Arizona to central California 

 and according to some authors as far as Oregon. It is also reported from 

 Mexico, as noted since our map was printed. East of this the species is 

 found in all the Rocky Mountain region of Utah, Colorado and Wyoming. 

 East of the Rocky Mountains it occurs in all tlie Gulf states excepting 

 Florida, although it does not appear anywhere to touch the Gulf, but has 

 been received from central Texas (Belfrage), is mentioned by Gosse from 

 central Alabama, and figured by Abbot fiom Georgia. It occurs abun- 

 dantlv througliout New P^ntjland.
