34. Huphina siamensis, sp. n. 



Nearly related to //. lea, larger; the males with con- 

 siderably narrower black outer border to all the wings, the 

 veins on the apical third of primaries much more narrowly 

 black-bordered (not by any means subconfluent, as in //. lea) ; 

 the orange patch on the secondaries much larger, but less 

 vividly coloured : below, the black veins on the primaries are 

 more slender and the yellow submarginal spots are much 

 larger and more conspicuous, whilst the disk beyond the cell 

 is of a clearer paler yellow ; this is also the case in the female, 

 which in other respects much more closely resembles that sex 

 of //. lea than the males of the two species do.

The type is our male from Moulmein incorrectly figured 

 in Doubleday's ' Genera of Diurnal Lepidoptera ' under the 

 name of Pieris clemanthe. 



36. Huphina hespera, sp. n. 



Above very like H. lea, but the female showing scarcely 

 a trace of the tawny flush on the secondaries ; below, all the 

 dark markings are much broader and more confluent, the 

 apical area of the primaries being deep vinous brown, 

 enclosing two or three white dashes beyond the cell and an 

 imperfect submarginal series. In the wet phase nearly half 

 the secondaries is occupied by the dark brown outer border 

 and most of the submarginal spots are obscured ; the costal 

 border of the primaries and the subcostal and median veins 

 are much more heavily black-bordered than in the allied 

 species. In the dry phase the border of the secondaries is 

 reduced to half the width. Intermediate examples also occur 

 in which this border is slightly wider than in the extreme 

 dry types.
