stems of the grass, low down, with a network of pure white 

 silk for pupation." 



April to June on Triticum repens and its var. littorale, and 

 other coarse grasses. 



Pupa long and rather slender, yellowish green. In an open 

 network cocoon among grass stems. About four days before 

 emergence the wing cases of the pupa assume a golden brown 

 colour, and the eye-covers a brilliant crimson, changing in 

 two days to black ; the tips of the antennte cases also black. 

 Attached to a carpet of silk, by a silken girth and the anal 

 hooks, within the chamber formed by the larva among the 

 grass stems. 



Of species now known to exist as British the present is the 

 latest added to the British fauna. In July 1888 Mr. F. W. 

 Hawes, desiring to improve his series of H. linca, collected a 

 number of specimens in Essex, and, among them, brought 

 home three which, after having been for some time supposed 

 to be varieties of that species, were ultimately recognised as 

 belonging to the present. In the following year specimens 

 were taken by Mr. J. T. Carrington, who had assisted Mr. 

 Hawes in identifying the species, and it has in the subsequent 

 years been taken in plenty, the most favoured locality being 

 along the north bank of the Thames, at Leigh, Southend, and 

 Shoeburyness. Upon the publication of this discovery much 

 examination of the specimens of H. linca in collections 

 ensued, with, in some cases, satisfactory (?) results. Mr. J. 

 Jenner Weir found that it had been taken many years ago in 

 either Kent or Sussex ; Mr. H. W. Barker had found it in 

 Sussex, on chalk formation ; Mr. W. G. Mackmurdo had 

 taken it in the years 1863-5, at Felstead, Essex ; Mr. J. N. 

 Young in 1880 at Clumbei-, Notts; Lieutenant Gervase F. 

 Mathew in 1886 at Harwich, Suffolk; and I found two old 

 specimens in the British collection in the Museum at Taunton, 

 which had almost certainly been taken in the West of Eng- 

 land. In 1890 it was found also at Wicken fen and at
