insect on the Continent ; and Pallas relates that he 
saw such extensive flights of them in the vicinity of 
Winofka, that he at first conceived them to be flakes 
of snow. The female, indeed, is very prolific, and 
covers her eggs, which she deposits on the extremity 
of a hawthorn branch, with a coating of varnish, so 
effectually weather-proof, that they remain in secu- 
rity (sometimes, it is said, for several years), till cir- 
cumstances favour the exclusion of the larvae. The 
chrysalis is very obtuse anteriorly, and of a yellow 
colour, streaked and spotted with black. (PI. III.
