D. ornata Mg. Apparently a rare species; there are 
examples in the British Museum from Cusop, Hereford, 
taken by Lt.-Col. Yerbury on the undersides of butter- 
burr leaves, while Dr. W. Wallace informs me that he has 
taken it in the same situations near Grimsby. The species 
is easily distinguished by the position of the vein Cu,a 
(great cross-vein) and by the four large dark spots on the 
costa, the first and fourth being at the base and apex of 
the wing. The vem Cu is entirely dark and dark- 
bordered, not spotted; the species first recorded by 
Verrall as D. ornata, which has this vein spotted, is really 
D. goritiensis. 
D. goritiensis Mik. Apparently common along the south 
coast from the Isle of Wight to Cornwall. I took it abun- 
dantly last June on wet cliffs and rocks on the shore at 
Sidmouth. An interesting aberration from Lelant, Corn- 
wall (Zt.-Col. Yerbury) is in the British Musuem. In this 
specimen (a male) the only dark spot on the wing, apart 
from the stigma, is a cloud in the upper basal cell beneath 
the base of Rs. The yellow ves R, and Cu and the 
structure of the hypopygium prove its identity. 
D. lucida Meij. I first recognised this very distinct 
species from a female taken by Mr. A. H. Hamm at Hogley, 
Oxford, 10 viii. 1915, and presented by him to the British 
Museum; last June I found it at Weston Valley, near 
Sidmouth; I believe it was common there, though I only 
took away one specimen. There are other examples in the 
late Mr. F. C. Adams’ collection in British Museum, col- 
lected by Dale, and named D. ornata, to which this species 
bears a considerable resemblance, All these specimens
