Eurema euterpe, referred to above, E. dclia Gram., flying with it 

 though not nearly so numerous, and in the field hard to distinguish 

 from it until captured, so rapidly does it move its wings with the tell- 

 tale band on the primaries' lower margin. And as for the delia 

 females I suspect that many a specimen was overlooked, being misled 

 by its euterpe -like dress. E. jucunda Bdv. all but escaped me too, 

 looking like a faded dclia; while E. nicippe Cram., the fourth, de- 

 manded sharp attention to differentiate the occasional example from 

 the hosts of male Eurymus eurytheme. Of the Hesperids Pyrgus 

 tessellata Scud, was distinctly a meadow species, very abundant, 

 rarely rising in its flight above the tops of the grasses, that is, above 

 eight or ten inches from the ground surface, and from the freshness 

 of many of the specimens noted evidently a brood just emerged. 

 Lerodea eufala Edw. was also taken in the grass; but Atalopcdes 

 campestris Bdv. was found only on the aster blossoms, which dis- 

 appeared during the last week in October. Another species that 

 proved especially partial to the asters was Dione vanilla Linn., most 

 numerous, and in life with the most brilliant red coat of any of our 

 red butterflies. It was a constant joy to see them clinging to the 

 swaying stems, generally two or more on the same flower spray, or 

 fluttering in their quest for a more tempting feast. Phyciodes tharos 

 Dru. was everywhere in the grass; Vanessa virginiensis Dru., better 

 known to most of us as huntera, was another old acquaintance, but 

 by no means common ; while in the fields Euptoieta claudia Cram., a 

 very few Danaus archippus Fab., and an occasional ubiquitous 

 Pieris rapes Linn, were noted. The dry limerock road in front of 

 the house had its frequenters too, including Polygonia interrogationis 

 Fabr., and the little peacock Junonia cosnia Hubn. Close to the house 

 in a bed of garden asters Papilio cresphontes Cram, lingered too long 

 for his own good; while flying high overhead, bound for other parts, 

 black swallow-tails were sometimes seen, of which the only one 

 taken proved to be P. philcnor Linn. 



My most important observations however were the following, one 

 having to do with a new record for the section treated of, the other 

 with an interesting manifestation of instinct in a common southern 

 species. On the fourth of November, a bit further afield than I was 

 wont to wander, I saw what I supposed was a tailed Polygonia, but 

 having netted it discovered I had taken an Ana a, presumably portia
