! Acerbas duris. 



Carystus duris, Mabille, Comptes Rendus Soc. Ent. Belg. iii. no. 31, p. lix (1883). 

 Lotongus duris, Semper, Schmett. Philipp. p. 289, pi. xlix. fig. 7, ? (1892). 

 Carystus mabillei, Staudinger, MSS. 



Hah, Philippines {Semper); Kina Balu, Borneo (Waterstradt). 



Though the characters given in the table seem sufficient to separate the few specimens 

 (only six in all) that we have seen of these two species, yet the occurrence of both of 

 them in Borneo throws some doubt on the constancy of the differences, and we have 

 seen no female of martini as yet. The female of duris is similar to the male. The 

 male genitalia of the two forms do not afford material for their separation. 



! Acerbas nitidifasciata, n. sp. (Plate XX. fig. 9, 6 ; Plate XXIV. fig. 51.) 

 Besides the characters given above this species may be distinguished from 

 A. martini by its larger size (expanse 47 mm.) and the broader white band on the 

 hind wing below. The latter at its greatest breadth extends from the cell at the level 

 of the base of vein 2 as far as the apical third of cells 4-5 ; in A. martini this band at 

 its greatest breadth extends from the cell at the level of the base of vein 2 only half- 

 way across cells 4-5. In A. nitidifasciata the apex of the lower lobe of the clasp is 

 simply rounded and serrate ; in A. martini the same part is broadly truncate, and its 

 inner angle is produced into a long strap-shaped lobe, rounded at the apex. 

 Hal. Labuan (fide Staudinger) ; N. Borneo (Fryer); Pulo Laut (Boherty). 



Pudicitia. 

 Pudicitia, de Niceville, Jour. Bomb. Nat. Hist. Soc. 1895, p. 379. Type pholus, de Nicev. 



This genus has been established by Mr. de Niceville for his Parnara pholus, an insect 

 of the size and shape of P. assamensis, Wood-Mason and de Nicev., and having deep 

 yellow hyaline spots on both wings, those on the hind wing forming a transverse discal 

 series. The course of vein 5 in the fore wing is not stated in the description, but vein 

 la in that wing has in the male "a narrow brand formed of modified black scales 

 placed anteriorly against it along its basal second and third fifths." 



Pudicitia is compared by its author with Erionota, Mab.
