SPECIES 13.— AGROTIS SAGITTIFERA. Platf. XXIV., Fio. C. 

 SvNosYME.— A'oc/ua sagillifera. Hiibncr? Treitschke ? Stephens, III. Haiist., -J, 11!). 



Mr. Stephens is tlio only author who has noticed thi.s species as British, and as he considered it doubtful 

 whether his specimens were the true sagittifera of Iliibner, it will be necessary to quote his description of them ; 

 to which we are only able to add, that in the opinion of Mr. Bentley they are but another variety of A. Tritici. 

 lie has not, however, introduced them as sueli in his observations on that species in the "Entomologist" for 

 February last. 



Expansion of the fore wings lyW inch. " Head and thorax griseous, mixed with white ; anterior wings 

 griseous, clouded witli white, with a longitudinal, black, arrow-shaped line at the base ; the anterior sticnia is 

 rather elongate, ovate, whitish, with the centre pale ashy-brown ; the posterior griseous in the centre, marcined 

 with dusky and white ; the space between, as well as at tlie base of the anterior stirjma, deep fuscous ; the 

 teliforni stigma is rather elongate, and has a slender black streak extending from it : on tlic hinder maroiu is an 

 angulated pale stripe, having a few dusky wedge-shaped lineolaj within : the margin itself has a row of minute 

 black dots ; on the costa, near the apex, is a fuscous spot, in which are three white dots : the posterior win"s 

 are whitish, with the margins dusky; the male has tlie posterior wings milk-white." Taken in the neighbour- 

 hood of London.

This supposed species measures nearly 1.', inch in the expansion of tlie fore wings, wliicli arc of an asliy brown 



colour, but variable in tone, with the costa narrowly dark and interrujitcd ijy several pale dots ; the base of the 



wing is pale and irrejularlv clouded, with a double waved streak before tlie basal stigma, almost obliterated 



towards the costa ; the basal stigma is small and pale, preceded by a short black dash, the space between it and 



the ear-shaped stigma being sometimes dark ; the latter is pale, but darker iu the middle, and with a dusky 



margin ; the supplemental stigma is dark -coloured, with a black edge ; beyond the second stigma the wing is 



pale, with a row of black dots ; a triangular brown spot near the apex, anil a rather broad dusky apical margin 



with a row of minute black dots. The hind wings in the male are whitish, with a slightly dusky border, those 



of the female being rather darker-coloured. The caterpillar is ashy brown, with dark dots on the sides, and a 



reddish head. It is said, by Treitschke, to feed on the ladies' bed-straw in May, and the moth to appear in 



Jul}-. Treitschke distinguishes it with much care from A. vitta, which Boisduval gives as a variety of it. 



A. vitta is, however, regarded by Mr. Bentley (Entomologist, p. 257) as a variety of A. Tritici, of which protean 



species, perhaps, A. aquilina may also eventually prove another variety. Found near London, and on the coast, 



as well as in Glamorganshire.
