me to include it, together with the Lithosia, amongst the Thieida, 

 which accords with the ideas of Latreille in his Genera Crustace- 

 orum, &c. V. 4. p. 221. 



As it is clear that these species connect two families, the 

 necessity of forming them into a genus will be obvious : the name 

 Eidejiia alludes to the pretty disposition of the coloured scales in 

 the upper wings. 



Ealepia Crihrum has never before been described or figured in 

 any British work ; and I am indebted to the assiduity and kind- 

 ness of my friend, J. C. Dale, Esq., for the specimens that enrich 

 my cabinet, as well as for those which were given to me to make 

 the dissections necessary to illustrate the genus. Mr. Dale says 

 they settle much upon heath in particular spots, as well as upon 

 the stalks of grasses, with their wings closed round them like 

 Bomhyx putcJiella Linn. (Deiqpeia pnlc/ira Steph.), and the true 

 Lithosia and Crambi. Several males have been taken by Mr. 

 Dale in different years, the end of June and beginning of July, 

 upon Parley Heath, HampsWre ; and two females were captured 

 on the same ground about the middle of June last year : Mr. 

 Bentley has also taken the male near Ringwood, in the same 

 county. A specimen of the male is figured in the plate ; the 

 females differ only in having a larger abdomen; the larva is at 

 present unknown. Of the other species E. grammica, which is 

 equally rare, (the larva of which is well known, is found in May, 

 and is a general feeder,) specimens have been taken at Windsor 

 in October, which are now in the cabinets of the British Museum 

 and Mr. Stephens : Mr. Donovan also found it in September 

 near Manachty in the Isle of Anglesea, and has figured it in his 

 British Insects, v. 13. pi. 450. 



Alopecunis agrestis (Field Fox-tail grass) is given with the 

 insect.
