AGEOTIS AQUILINA. 21 



of the genus during the day, and crawled forth to 

 attack their food at night, and were full-fed by the 

 20th June, and the perfect insects emerged from 

 July 24th to 29th, varying much in markings, no two 

 specimens being alike, excepting in the general tint of 

 warm brown, peculiar to this species. 



The larva, when full-grown, is an inch and a half 

 long, cylindrical, and rather shining. The head is grey- 

 brown, mottled with blackish ; the back dingy brown, 

 a dorsal line of rather paler grey-brown, the subdorsal 

 line black, edged below with a thin line of grey-brown, 

 and which, like the dorsal line, runs through the 

 blackish plate on the second segment ; to this succeeds 

 a broad stripe of dingy blackish-green, then another 

 thin line of grey-brown, followed by another broad 

 stripe of dingy blackish-green, the black spiracles 

 being situated along its lower edge ; the belly and legs 

 grey-brown, the warty spots dark brown and not very 

 conspicuous ; the general aspect of the larva very dark 

 and dingy. (W. B., September, 1865 ; E.M.M., II, 133,

Agrotis obelisca. 

 Plate LXXII, fig. 4. 



I received, 5th June, 1870, from Mr. Wilson, of 

 Edinburgh, eight larvae, little and big, of an Agrotis, 

 said to be obelisca. The smallest were very dark 

 indeed, and had a pattern on the back of dark marks 

 through which runs the dorsal line, thus : (J) . 



Their natural food is asserted to be Helianthemum 

 vulgar 'e. 



The ground-colour of the back is greyish-brown, 

 the sides of a smoky or blackish-green. The sub- 

 dorsal stripe is rather broad and dark blackish-green, 

 the dorsal line pale grey, outlined with blackish-green ; 

 properly speaking, the subdorsal line is thin, of pale 

 greenish-grey, and edged above broadly with the dark
