 extremity of vein 3, slightly emarginate from 3 to 1, the anal angle 

 rounded. Antennas short, about half the length of the costa of forewing, club 

 moderate, with a short, pointed crook ; palpi upturned, second joint densely scaled. 

 third joint almost entirely concealed ; hind tibiie with two pairs of spurs. The mal(-

Type, Hesperia oceia, Hew^itson. 



Note. — This genus has heretofore been considered by most authors as monotypic ; 

 with this we have never agreed, and have asserted our opinion in several of our memoirs 

 that the Indian forms were different to the Philippine type of Hewitson's oceia, and 

 that Moore's unicolor differed from lioth. As Elwes' and Edwards' dissections of the 

 genitalia of Bornean and Chinese examples (which superficially resemble typical 

 Philippine oceia quite as closely as the Indian examples resemble that .species) pro^■ell 

 their distinctness from the Indian form, and as Davidson, Bell and Aitken, who bred many 

 of the so-called Baoris oceia, make no mention of any variations, we thought it advi-salJe 

 to settle the matter by having several examples of all the forms in our po.ssession dissecteil 

 by a competent authority. We sent fourteen males from the Philippines, Borneo, China, 

 the Andamans, Nikobars, Burma, Sikkim and Assam, to Dr. Chapman, who has dtan^ 

 such excellent work on the genitalia of the Lepidoptera, and we hereby append his 

 report, and beg to thank him most heartily for the trou])le he has taken in the matter. 



We give enlarged photographs of the genitalia of all the four species on Plate 

 No. 825a. 



Dr. Chapman says the result of his dissections is as follows : — • 



1. Typical oceia from the Philippines, very distiuct. 



2. Typical simillima from Brunei, North Borneo, \ 



typical unicolor from Darjiliug, and one / The same as each other, i.e. one species, 

 example from Burma. J 



3. Typical leechii from Omeishan. 



4. 3 typical sihkima from Sikkim; 3 typical scojndi- 



fera from the Andaman and Nikobar ,
