510 LORD WALSINGHAM ON THE [Nov. 17, 



margin ; 7 and 8 one after another out of 6, the one before, the other 

 behind the origin of 5, 7 to costa; 9, 10, and 11 separate ; a small 

 supplementary cell caused by the continuation of 6 to between 10 

 and 11. 



Hind wings narrow, evenly lanceolate, acuminate ; with very long 

 cilia extending to the base of the costal margin. Neuration : 8 veins ; 

 3 and 4 separate ; 5 and 6 from a common stem, 6 to apex ; 7 parallel 

 with 6. 



Abdomen somewhat flattened. 



Legs with the hind femora much flattened and somewhat concave 

 at their outer sides ; hind tibiae hairy. 



This very inconspicuous and ordinary-looking Tineid differs entirely 

 in its structural characters from any genus or subfamily hitherto 

 described ; the neuration is very peculiar, somewhat resembling that 

 of CEcocecis, Gn., to which, however, it is not allied. 



A single female, possessing the same remarkable neuration which 

 characterizes this genus, differs in the structure of the palpi and in 

 the slightly greater expanse and breadth of the wings. Having at 

 first regarded it as a separate species, I am now strongly convinced 

 that it is but the other sex of Dendroneura prcestans. A description, 

 so far as it indicates structural differences, is appended : — 



Labial palpi porrected, scarcely twice the length of the head ; 

 second joint with a projecting brush of scales below, apecten of three 

 or four separate hairs on its outer side near the apex ; apical -joint 

 smooth, short, scarcely more than half the length of the second 

 joint, not recurved nor erect. 



Abdomen laterally compressed; ovipositor extended, long. 



If any reasonable doubt can be entertained as to the identity of 

 this female with the male on which the genus is founded, it must be 

 based upon the difference in the shape of the head, which is of the 

 ordinary form, not flattened or fringed at the side in the manner so 

 remarkable in the type. 



Dendroneura prcestans, sp. n. 



Antennce and palpi pale greyish ochreous. 



Head pale greyish ochreous ; face shining white. 



Thorax dull greyish ochreous. 



Fore wings dull greyish ochreous, with a narrow transverse line of 

 slightly raised brownish fuscous scales before the apex, at the upper 

 end of which is a minute oblique spot of similar scales turning back- 

 wards from the costal margin ; cilia dull greyish, with an ochreous 

 tinge. 



Hind wings pale greyish, with a slight ochreous tinge ; cilia greyish, 

 tinged with ochreous towards their apex. 



Abdomen rather shining, ochreous. 



Legs shining, pale cinereous ; tarsal joints unspotted.
