Distribution (24:.s). Tliis l)iitteitl\ hdoiigei to tlic Canadian fauna, 

 altlioui;li it lias not been detected in all the ])laces we should have antici- 

 pated and is very aliundant in certain spots beyond these boundaries. For 

 in.xtaiK'o, it i.< not reported tVoni (^uel)ec, Montreal, Ottawa nor the AVhite 

 Mountains, while Mr. Lintner has ob.-ier\cd large Hocks in a single spot 

 in the vicinity of Albany, New York — the nearest point to New England 

 at which it has yet been discovered. Mr. Edwards even writes that he 

 has seen several specimens in the collection of Mr. Akhurst of Brooklyn, 

 N. Y., which were .said to have been taken in that vicinity, while, on the 

 other hand, Mr. Coiiper found it "common" on the northern shore of the 

 Gulf of .">t. Lawrence opposite the Mingan Islands, a point closely ap- 

 proaciiing the Hudsouian fauna. MiJschler reports it from the same 

 region, 55° 35' W. Strecker quotes it from Anticosti, Thaxter brought it 

 from Cape Breton, and it is pretty certainly this species which Edwards 

 describes under the name of aster, taken in Newfoundland by Mead. In 

 the west it has been taken as far south as London abundant (.Saunders) 

 and Toronto, Ont. (Fletcher). Michigan (Edwards), northern Illinois 

 (Wortbington) and AVisconsin "not i-are" (Hoy) ; but it belongs more 

 properly farther north, for it has been taken at Charleton Island, Hudson 

 Bay (Macoun t. Fletcher), at the mouth of the Saskatchewan (Scudder), 

 LakeLabache (Edwards) and Fort Simpson on the McKenzie (Edwards). 



It has never been taken in New England, Init I do not see why it should 

 not be found on some of the sandy plains of the Connecticut Kiver where 

 Lupinus abounds. 



Oviposition. By confining the butterfly over Lupinus many eggs 

 were laid, generally on the under side of the leaves or on the stalks, 

 sometimes on the upper. They hatch in June in from seven to eight 

 days. 



Food plant. The caterpillar has been taken in the field only by Mr. 

 Saunders, who found it upon Lupinus perennis Linn, one of the Legumi- 

 nosae. The European species to which it is closely allied are reported to 

 feed upon Melilotus, Genista, Hedysaruni, Trifolium, Onobrychis and Co- 

 lutea. Our species feeds with the utmost freedom on Lupinus. which 

 grows in abundance in the locality near Albany where Lintner finds it, 

 but it must find other food in the high north. Edwards states that it also 

 feeds on Ccanothus, one of the Kbamnaceae. 



Habits of the caterpillar. In the spring of 1887 Mr. Lintner kindly 

 guided me to bis happy hunting grounds at Centre near Albany, when for 

 the first time I had the pleasure of making the personal acquaintance of 

 this butterfly, of obtaining eggs and rearing the insect through all its 

 stages. The caterpillar eats its way out of the shell by biting a hole at
