242 MESSES. H. J. ELWES AND JAMES EDWAEDS : 



This species differs from any form of _/V. feisthamelii in having on the fore wing a 

 triangular spot, which occupies the basal third of cell 3, included in the white band. 

 Very few specimens are known, all females.

 Java (fide Mabille) ; N. Borneo (Pryer, in coll. Bothschild). Cf. p„ 215 ante. 



(Erane, gen. nov. 



Antennae two-thirds the length of the costa ; club slender; apiculus about one-fourth 

 as long as the club. Palpi laxly scaled, second joint ascending, third long, acicular, 

 erect. Fore wing (male) : costa one-third longer than the dorsum ; termen straight 

 from the tornus to vein 5, subequal in length to the dorsum, vein 5 with its basal 

 portion receding from vein 6 and therefore arising evidently nearer to vein 4 than to 

 vein 6. Species blackish brown above, with an oblique white abbreviated discal band 

 between vein 2 and the upper edge of the cell. Hind tibiae with two pairs of spurs. 



This genus contains at present the two species mentioned below, and as both of 

 them exhibit the characters given above it cannot be said that one is more typical 

 than the other. 



They may be thus distinguished inter se : — 



Subtornal blotch on fore wing below pale brown. Fore wing (male) apparently 

 narrower, by reason that the angle between the dorsum and the straight 

 part of the termen is about 115° necera, de Nice"v. 



Subtornal blotch on fore wing below white, almost as pure as the discal band. 

 Fore wing (male) apparently broader, by reason that the angle between the 

 dorsum and the straight part of the termen is about 100° microthyrus, Mab.

 There is a specimen in the Hewitson collection from Singapore unnamed.

 Notocrypta microthyrus, Semper, Schmett. Philipp. p. 317 (1892). 



Hab. Luzon, E. Mindanao (Semper) ; Mindoro (coll. Staudinger). 



Herr Semper was mistaken in his statement that he had not the female of this 

 species, the specimen submitted to us is undoubtedly of that sex. 



In this species the pale band on the fore wing below is continued to the costa, and 

 there is a tendency to the acquisition of this character in some females of CE. necera.
