Show 610 MR. H. H. DRUCE ON BORNEAN LYCEENIDEE. [June 18, described species are much alike, but in the examples before me do not show any variation. Dr. Staudinger has received a considerable number of female metasuja from Kina Balu. CHERITRA, Moore. C H E R I T R A FREJA, var. OCHRACEA, nov. Hesperia freja, Fab. Ent. Syst. iii. p. 263 (1793). Sithon freja, Druce, P. Z. S. 1873, p. 351. Cheritra freja, Distant & Pryer, Ann. & Mag. Nat. Hist. ser. 5, vol. xix. p. 269 (1887). Differs from the Continental Indian form by the whole of the fore wing as well as the costal half of the hind wing below being ochraceous, and by the inner black band towards the anal angle being much broader and less broken. Sandakan (Pryer); Labuan (Low and Waterstr.); Sarawak, S.E. Borneo. This apparently is the usual Bornean form of the species, as in a large number of specimens before me there is no variation. Mr. Distant's figure * of C. freja shows a form intermediate between the Indian and Bornean representatives. CHERITRA PALLIDA. Sithon pallida, Druce, P. Z. S. 1873, p. 352, pi. xxxiii. fig. 3. Sithon pallida, Distant & Pryer, Ann. & Mag. Nat. Hist. ser. 5, vol. xix. p. 268 (1887). Sandakan (Pryer) ; Labuan (Low). I have examined the type of this species and find that it is nearly allied to C. freja var. ochracea, the tails on the first median nervule being broken off. It agrees in neuration exactly with that species. On the upperside it can be distinguished by its rich purple colour in all lights, and by the distinct and even black margins. On the underside it differs from C. freja var. ochracea only by the black markings being more extensive and by the inner black band being situated higher up the wdng. The metallic blue line is placed on the black, not above it as stated in the original description, and the black spot in the submedian interspace, which in 67. freja and in var. ochracea is nearly obsolete, is in C. pallida large and distinct. The type specimen, now in Messrs. Godman and Salvin's collection, is the only specimen I have seen. It is, I believe, a perfectly good and distinct species. RITRA, de Nicev. Butt.
