the thorax being longest. The female is larger than the male. The male

_ Mr. Pettit says “the insects were taken in East Oxford, July 2nd, on 
a few strawberry plants in my brother’s garden. The plants, perhaps 
‘nearly ioo in number, had been nearly all denuded of their leaves, and a 
search in the evening having failed to reveal the authors of the mischief, I 
examined them again in the heat of the day, and found the little culprits 
actively engaged in nibbling away the remaining shreds of the leaves 
They appeared to chew the fragments into a pulp, and carry it away, but 
the little time I spent in observing them was insufficient to determine 
anything further respecting their habits.” 
Doubtless the leaves so consumed were used either in the construction 
or lining of their nests.—W. SAUNDERS. 
NOTES oN Some BUTTERFLIES AND THEIR Larva.—We extract the 
following interesting details in reference to the life history of some of 
our butterflies, from a letter received from Mr. W. H. Edwards, of Coal- 
burgh, West Virginia, U. S., under date of October 12th :—W. S. | 
“ I have in all, probably 200 eggs of Argynnis Cybele, some deposited 
on violet leaves, and some on the cloth that covered the keg in which I 
confined the females, with the growing plant, and I suppose half of them 
have given larvae. I also had quite a number of eggs of Aphrodite, and 
a few larvæ from them. I endeavored this time to avoid dryness, as the - 
contrary state seemed to be most natural to these lar\æ,and I attained this 
end by placing wet sand in the bottom of a glass goblet, in which sand 
were stuck small sprigs, or single leaves of different sorts of wild violets, 
all the species I could find hereabouts at this season; I also tried the 
pansy. The goblets I covered with damp cloths.” 
“The young larvæ, as soon as hatched, were transferred to these various 
leaves, and as none have died—although three weeks have elapsed since 
the first were hatched—I think they must be healthy. They are but little 
bigger than when hatched, but must have eaten for some days, as they 
were then pretty lively, but I have been unable to discover on the leaves 
any visible evidence of feeding. I presume they eat the surface of the 
leaf, not the edge. For a week past I have seen no sign of motion, but 
the larvae remain in the same position. In the grooves of the larger 
violet leaves are several, three or four in a row, and I notice that the
