444 LEPIDOPTERA. 



colour chestnut-brown, the wing-cases greenish, or entirely 

 brown. (X. M. \\.) 



I am indebted for all that I know about this species, and 

 for specimens, to Mr. N. ^[. Eichardson. He discovered it 

 at the Isle cf Portland in the 3-ear 1887, and has taken a few 

 specimens, with Mrs. Richardson's assistance, every year 

 since tliat time, a few on the wing at night, but the majority 

 at rest upon flowers, also at night. After some difticulty 

 they also discovered the larva and food-plant. Within 

 the ] ist year or two the insect has extended its range — or a 

 new locality for it has been discovered, by Mr. E. R. Bankes 

 — on the coast of the Isle of Purbeck in the same County of 

 Dorset ; but, so far as is at present known, it has not been 

 found in any other locality in the whole world. It is nearly 

 allied to — - though clearly distinct specifically from — E. 

 iUofilla, Z., found in Southern Europe, and commonly in 

 South Africa ; E. prodromclhi, Hh., found in Central and 

 Southern Europe, and in Asia ; and to the rare E. aderis, 

 Stgr., a French species, unknown to me. 



2. E. farrella, CVrt. ; boisduvalliella, (?«. — Expanse 



5 inch (17-2U mm.). Fore wings elongated, narrow, pale 

 drab, darker toward the costa, where also is a silvery-white 

 longitudinal stripe ; discal dot black. Hind wings pale 

 smoky-brown. 



Antennas of the male simple, but the basal joint thickened, 

 and the second bent and channelled, red-brown ; palpi thick, 

 porrected, greyish-white ; head pale grey-brown, with a white 

 line down the inner- side of each eye ; thorax reddish-drab; 

 abdomen whitish-lirown. Fore wings narrow ; costa nearly 

 straight ; ape.x bluntly rounded ; hind margin almost 

 straight and rather oblique ; pale yellow-brown or drab, 

 shading toward reddish-brown above the middle, where it is 

 cut off by a shiny white sub-costal stripe from the base to the 

 apex ; this stripe is so straight that it departs from the costal 

 margin a little in that portion which is slightly arched, the
