THE ENTOMOLOGIST. 97 



when I returned I found all had buried themselves in the 

 earth provided for that purpose. I did not disturb the pupae, 

 and one morning the next year I found in my breeding-cage 

 a perfect imago of Deilephila Livornica. I have troubled 

 you with this account, as it must show how similar the larva 

 is to that of Smerinthus Populi, and that in this case it fed 

 on the white poplar, and not on the lady's bedstraw as 

 generally supposed. The other specimen flew to a light in 

 a window on the 3rd of August, 1868. You may be surprised 

 that I did not announce these captures before, but at the 

 time I made them I did not know of your valued 'Entomo- 

 logist.' — T. Edward Morris ; Eimsdale, Wolverhampton. 



In the matter of Dianthcecia Barrettii. — Having seen 

 one of the specimens of D. conspersa bred by Mr. Moore, 1 

 have no doubt whatever about it being an aberration of that 

 species. How any person having " form," and not colour- 

 blind, can compare narrow-winged, silky, smooth, ochreous- 

 brown specimens to broad-winged, rough, greenish and 

 colcothar-coloured blotched Barrettii, I am at a loss to con- 

 ceive ; and as Mr. Moore's description of the larvae he bred 

 them from is a good practical description of the larvae of D. 

 conspersa as bred by myself, the matter may well end here, 

 they being undoubtedly D. conspersa, var. — C. S. Gregson ; 

 May 4, 1870. 



Have any Lepidoptera the power of rendering them- 

 selves invisible? — Have any of the Lepidoptera the power 

 of rendering themselves invisible when pursued ? When 

 in France and Switzerland last autumn, I had the good 

 fortune to meet with many of the Queen of Spain Fritillary 

 (Lathonia), and although the ground above which they were 

 flying was quite clear from underwood, yet just as I was 

 about to strike with my net they would often appear to 

 vanish in the most extraordinary and unaccountable manner. 

 I at first thought they must have dropped suddenly to the 

 ground, like many of the moths; but though I most narrowly 

 searched the spot, yet I could never find them. Can the 

 large quantity of silver under the wings have the effect of 

 dazzling the eyes in the bright sunshine ? — John Gatcomhe ;

Eupithecia satyrata. — Yesterday (May 8th) two specimens, 

 male and female, emerged at 8 a.m. At 9 a.m. they paired,
