4 Lord Walsingham's monograph of the genera 



it to the neighbourhood of Butalis or the Elachistidce : 

 and in the case of Tinageria, Walker and Butler again 

 agree that the genus seems to connect the jEgeriidce 

 with certain families of the Tineites. Felder and 

 Kogenhofer place the type of the genus with a "?" in 

 Eretmocera, and a specimen in my own collection, 

 received from Mr. G. F. Mathew, was named by Mr. 

 Meyrick before I received it, " Atkinsonia lineata, Walk.," 

 showing that all these authorities concur in classing 

 Tincegeria with the Tineites (Tineina, Stn.). 



I am unable to regard the genus Acridura as allied to 

 any of the genera here mentioned ; its long, slender, 

 and pointed abdomen, its Pyralidiform wings and neura- 

 tion, and certainly its general appearance, seem to 

 separate it very widely from Tincegeria at the one end, 

 as well as from (Edematopoda and Eretmocera at the 

 other end of our proposed series. 



The more important structural characters of the genera 

 included in this paper are as follows : 



1. Antennae thickly clothed with more or less long 

 projecting scales, extending to a greater or less distance 

 along them. 



2. A greater or less tendency to transparency in the 

 hind wings. 



3. Legs often more or less clothed with projecting 

 scales upon or above the strong spurs. 



4. Bodies usually flattened, frequently brightly 

 coloured, and with strong lateral scales. 



4. Fore wings narrow, elongate, the costal and dorsal 

 margins nearly straight, and parallel to beyond the 

 middle ; the apex depressed. 



If any affinity to the Mgeriidce can be supposed to 

 exist in this group of genera, the species having trans- 

 parent hind wings may be regarded as in this respect 

 showing less departure from the characters of that 

 family than others with opaque hind wings. For this 

 reason, as a matter of convenience in classification rather 

 than as an arbitrary assertion of a supposed physio- 

 logical fact, however probable, I have here ranged the 

 genera according to their degree of approach in structure 

 and appearance to the " JEgeriida." They seem to 

 present a gradual and well-marked departure from the 

 typical form of that family by modifications traceable 

 step by step throughout the series, but it should be
