210 CAPTURE OF NOCTURNAL LEPIDOPTERA. 



and then during the month of October, but the specimens 

 were somewhat faded. 



Euthalia miata, — middle of October. 



Euthalia Psitticata begins to appear at the latter end of 

 September, and continues on the wing until the middle of 

 November; but is very susceptible of cold, particularly the 

 female; and only appears in warm humid evenings. The 

 males were all, more or less, faded ; but the females inva- 

 riably, to the 14th of November, retained their beautiful rich 

 green appearance. 



Hybernia connectaria, — beginning of November. 



Himera pennaria, — 20th of October. 



Thera variata, — middle of October. 



Juniperata, — one taken on the 22d of October, 1832, some- 

 what faded. 



Oporabia dilutata, — latter end of October. 



Cheimaiobia brumata, — middle of November. 



Margaritia ferrugalis.- — I captured one beautiful specimen 

 of this rare insect at the latter end of October. 



Sarrothripus degeneranus, — appears in the middle of Octo- 

 ber, and continues until the beginning of November. 



Oncomera podagraricB, — latter end of October. I cap- 

 tured this Coleopterous insect feeding upon the yew-berries. 



I have been induced to make the above observations upon 

 the appearance of the autumnal moths, as some are not re- 

 corded, and others very incorrectly. I thought they might be 

 useful to help to define the natural times of their appearance in 

 the imago state. I think I may say, that very few persons have 

 been out so many successive days and weeks for two years, or 

 have captured so many insects as myself, at such an inclement 

 period. I never lost a night; and was more generally suc- 

 cessful in capturing the rarer species when the nights were 

 warm and rainy. 



I will now describe, in as few words as possible, consistent 

 with clearness, the method of capturing the moths. I use a 

 bull's-eye lantern, with a powerful lens, — the larger the better ; 

 a pair of forceps, such as are generally used by entomologists,, 

 having the sides and bottom covered with white gauze, and about 

 six inches wide at the mouth when opened. Also I use a portable 

 sliding rod, or one with two lengths, jointed like a fishing-rod,
