inhabits S. Europe, and also occurs in China, and was probably there and 
in Hindostan before it came into Europe. These two species are thus 
examples of the two affinities of the European insect race, one with North 
America, the other with North Asia, and both increasing northward. 
Many genera of insects may be traced from the tropics northward, and 
their species may be observed in successively smaller circles till they attain 
their highest latitude. The distribution of the insect race by migration, 
and the variety thereby of their kinds in different regions, afford far 
greater proofs of the design, and contrivance, and wisdom of the Creator, 
than would have been manifested by their immediate appearance in the 
spots where they now exist. 
MISCELLANEOUS. 
Meir#a Harrisi.—Mr. W. H. Edwards, of Coalburgh, W. . Va. 
has, during the past summer, reared the larva of Melitea Harrisii. It 
was found feeding on Actinomerus squarrosa, a composite plant allied to 
Helianthus. It is probable that this species, so widely distributed, feeds 
on many of these closely allied plants in different localities.—W.

been found destructive to the foliage of 
some strawberry plants, by Mr. J. Pettit, 
of Grimsby, who has kindly furnished 
me with specimens. It was observed 
during the past season in the Township 
of Oxford. For the accompanying figure, which represents the female, I 
am indebted to my esteemed friend, Mr. Cresson, who very kindly made 
the drawing from which the cut was engraved. I am also indebted to him 
for the determination of the species. In the figure the insect is repre- 
sented on an enlarged scale, the hair line at the side showing its natural 
length. In both sexes the. head, thorax, and abdomen are green, and 
more or less densely covered with whitish down or short hairs, those on
