48 THE CANADIAN ENTOMOLOGIST. 



the winter ; these last two liad l^eeii shut u[) in a dark l)ox. Thus all my 

 four examples have produced perfect imagines. I can discern no specific 

 difference among these last three, inter sc. ; nor — what is much more re- 

 markable — between them and the one from the yellow and green chrysahs. 

 evolved on the 4th instant. The variation iii color, which distinguished 

 this individual, both in the larva and pupa (as 1 have described under 

 dates Aug. 16 and 30. 1834), seems, therefore, a very noteworthy circum- 

 stance. 



The liquid discharged by these butterflies, immediately after their evolu- 

 tion, is whitish, or cream-colored. The duration of the period of pupa- 

 repose is not quite uniform. It does not fall much short of eleven 

 months, from about the middle of August to about the middle of July. 

 And the evolution of my individuals kept in unnatural confinement through 

 the winter, does not sensibly vary, in seasonal period, from that of the 

 examples caught on Carbonear Island, last July. 



One of my evolved specimens, Ijefore it was killed for the cabinet, laid 

 five globular yellow eggs. So that I have seen this beautiful insect in all 

 its stages. 



P. Tunius, I.inn. Dwarfed in size, and paled in hue, from the normal 

 American condition. It is very uncertain in its appearance ; in some 

 seasons I have seen 15 or 20 examples ; in others not one ; it must always 

 be considered scarce. In my " Canadian Naturalist" I have given a few 

 notes of these species. 



Pieris Oleracca, Harr. Always alnmdant ; a nuisance in the cabbage- 

 gardens. The I St brood appears early in June ; the 2nd late in August 

 and early in September, at which times we find oleraceous plants studded 

 with the oblong, whitis-h eggs. I once saw a '^ lay an egg ; she alighted 

 on the under side of a leaf of horse-radish, and immediately, bending her 

 abdomen down, touched the leaf for an instant, and flew away. Looking 

 at the spot I found the white egg adhering by its end. I have had females 

 lay several eggs, when pinned on the setting board. I once found a pupa 

 which was all over of a light pellucid green hue ; this is always the color 

 when newly evolved, but in this instance the green hue remained without 

 any change till the imago appeared, some ten days after I had found it. 

 Another unusual circumstance was that this chrysalis, instead of being 

 horizontal, was bound in a perpendicular position, head downward to an 

 upright post. The June brood have remained in pupa through the winter.
