insect on the Continent ; and Pallas relates that he 

 saw such extensive flights of them in the vicinity of 

 Winof ka, 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.
