Besides the above, nearly all those species before recorded occurred last season, al- 

 though many of them were not so plentiful as the previous year ; on the whole I con- 

 sider last season was but an indifferent one for collecting generally, the drought the 

 preceding summer, combined with the havoc the birds made with the larvae, was no 

 doubt the cause that made insects scarce. I took a number of larvae last autumn, 

 principally Geometridae, which are now laid up. I expect they will produce me some 

 rarities. — S. Stevens ; 38, King Street, Covent Garden, February 3rd, 1846. 



List of Orthosis occurring near Doncaster. — The following list shows the dates of 

 appearance this year of the species of Orthosia, &c. that inhabit this neighbourhood. 

 The fine warm weather which occurred early in spring, by bringing the sallows into 

 blossom so much sooner than usual, threw considerable light on the habits of the 

 spring species, and explained especially the reason of O. leucographa having been 

 hitherto found so rarely in a perfect state. 



Feb. 21. Orthosia munda, made its appearance in the breeding-box of my friend, 

 Mr. Evans. 



Feb. 23. Took O. munda and O. cruda, with Calocampa exoleta, Glcea vaccinii and 

 satellitia, on sugar.

Feb. 25. O. stabilis, with Semiophora gothica, on sugar. 



March 10th. Took four O. leucographa, from willow blossoms in Wadworth Wood, 

 with O. munda, cruda, &c. Leucographa had been taken at intervals during the pre- 

 vious fortnight at Levitt Hag.
