570 L. de Niceville — Little- Known Butterflies from the [No. 3, 



narrow black line connecting the bases of the antennae. Thorax orange, 

 bat streaked and barred with black. Abdomen orange, ringed above 

 with black, the apex black. Legs mixed orange and black. 



This species is probably the one recorded from India by Capt. 

 E. Y. Watson as Odina hieroglyphica, Butler, in Jo urn. Bomb. Nat. Hist. 

 Soc, vol. ix, p. 422 (1895), on the authority of a specimen so named 

 in Colonel C. H. E. Adamson's MS. list of his collection from 

 Tounggya Sekkan, Upper Tenasserim, captured in February, 1881. 

 0. ortygia is nearest to the specimen figured by Distant in Rhop. 

 Malay., p. 470, n. 2, pi. xliv, fig. 25 (1886), as " Plastingia" hierogly- 

 phica, Butler, from Perak, but that figure shews the black bands 

 on the wings on both surfaces twice as wide. It is more distantly 

 allied to the true " Plastingia " hieroglyphic^, Butler, from Sarawak 

 (Borneo), from which it differs on both sides in all the black markings 

 being even more greatly reduced than in the Malayan Peninsula form, 

 all the orange markings therefore greatly enlarged. It may be said 

 (to judge from Mr. Butler's figure of that species) that it is a black 

 insect with yellow spots, while 0. ortygia is a yellow insect with narrow 

 black lines dividing the surface into irregular orange tessellations. 

 Dr. Martin and I have recorded 0. hieroglyphica from a single specimen 

 from N.-E. Sumatra, but that specimen is not available to me for com- 

 parison, being now in the collection of the Hon. Walter Rothschild. 

 Lastly, Herr Georg Semper in Schmett. Philipp., p. 314, n. 472, pi. 

 xlix, fig. 11, male (1892), has described " Plastingia " cuneiformis from 

 a single male from Mindoro in the Philippine Isles, which differs from 

 0. ortygia in having the black areas still more largely developed even 

 than in the Bornean 0. hierogliphica. All the species of this group 

 seem to be excessively rare, I know of only six recorded examples. 

 The type of the genus is Odina chrysomeloena, Mabille, Bull. Soc. Ent. 

 Belgique, vol. xxxv, p. cxiii (1891), from Mangkassar (Macassar) in 

 Celebes, which is probably quite distinct from the other described 

 species, though it is difficult to say how it differs from them as M. 

 Mabi lie's description is very short and is non-comparative. 



Described from a single example in my collection. 



Genus Inessa, nov. 



Male. Forewing, costa very straight, if anything very slightly 

 emarginate in the middle; apex acute; outer margin convex; inner 

 angle acute ; inner margin straight ; costal nervure short, ending on the 

 costa long before the upper end of the discoidal cell ; subcostal nervules 

 arising at progressively decreasing distances apart ; discoidal cell narrow,
