LYCAENINAE: EllORA LAETA. 819 



Miissachusctts, in tluit part of tlio Cuuueoticut valley where the river 

 passes between Jits. Tom and Holyoke, as well as in other sections of the 

 triassic traps of this valley which here find their culmination. In north- 

 ern Maine, with its vast forests, one is dependent on the clearings and the 

 older logging roads near open water, and the mountain elevations are not 

 so full of resources as elsewhere. Princeton, Mass., with its elevated 

 meadows, broken surface, abundant flowers and breezy hillsides and its 

 proximity to W'achusett is one of the best localities in New England. 

 Amherst in the same state is favorably situated, and so are several towns 

 in New Hampshire which Monaduock overlooks. Indeed wherever a local 

 collector of enterprise and spirit is to be foimd, it would almost seem, 

 from the variety of his Ciiptiires, as if his were a particularly favored 

 locality. I doubt indeed, if tiicre is a spot in New England (unless we 

 except the heavily wooded unsettled parts of northern Maine which are 

 not likely to be favored in many a year with the presence of a local ento- 

 mologist) where it would not be easy in a single summer to obtain 

 within a radius of ten miles one-half the nominal species of all New Eng- 

 land ; and there are not a few in which more than one hundred species 

 have been secured. Aliout Boston tlie choicest localities are the less 

 settled districts about the Blue Hills, Prospect Hill in Waltham, the 

 region about Waverly and the Middlesex Fells.

Full many a Ladie faire, in Court full oft 

 Beholding them, him secretly envide, 

 And wisbt that two such fannes, so silken soft, 

 And golden faire, her Love would her provide ; 

 Or that, when them the gorgeous Flie had doft, 

 Some one, that would with grace l)e gratifide, 

 From him would steal them privily away, 

 And bring to her so precious a pray.
