NEW AND LITTLE-KNOWN BUTTERFLIES. 143 



is unknown to the writer— (a) owing to females only having been des- 

 cribed : Gerydus petronius, Distant, O. gallus, de Nieeville, G. gatulus, 

 de Nieeville— (?^) owing to no mention by the describers of any male 

 sexual characters : Ger/jdus biggsii., Distant, G. dfucei, Semper, G. 

 lean-hus, Folder, G. stygianns^ Butler, and (?) G. plant us, Fabricius. 



12. LOGANIA WATSONIANA, n. sp., pi. Z, figs. 17, $ ; 18, 9. 

 Habitat : Upper Burma. 



Expanse : $, 1*1 to 1*4 ; 9, 1'l to I'd inches. 



Description : Male. Upperside, forew'mg with the basal two-thirds 

 greyish-blue, the apex and outer margin broadly black ; an oval out- 

 wardly-oblique discal white patch just beyond the discoidal cell, crossed 

 by the third median nervule, which, as in some species of Gerydus, is 

 swollen at the base (though not quite to the same extent) and bare of 

 scales. Hlndifing with the costa as far as the subcostal nervure and second 

 subcostal nervule black, the rest of the wing greyish-blue. Underside, 

 forew'mg dull fuscous, the apex mottled with ferruginous, the outer 

 margin broadly black ; a broad discal cur\ed white fascia, of about 

 oijUal width throughout, connnencing about the subcostal nervure and 

 ending on the inner margin. Hindwing fuscous, profusely irrorated 

 with ferruginous. Female. Upperside, foreio'mg differs from the 

 male in having the discal white patch less prominent, and merged into 

 the oreyish-blue basal area. Otherwise much as in the male. 



This species in the only Logania known to me which has a broad 

 discal curved white fascia on the underside of the forewing in both 

 sexes. L. sriica, Distant, aad L. malayica. Distant, are the only two 

 species in my collection which have the base of the third median 

 nervule in the male not swollen. 



Described from six pairs in Major F. B. Longe's and my own 

 collection, taken at Hsipaw in the Northern Shan States, roughly 

 between Lat. 22° and 23° and Long. 97°. I have u'lmed this species 

 after the late Captain E. Y. Watson, from whom I first received it, 

 who had made a speciality of the butterflies of Burma.
