UDAIANA. By H. Fruhstorfer. 188 
chryselectra subsp. nov., which differs from cycinna above in the lighter, more purple-blue colour. Under¬ 
side of the forewing pure white, not grey-blue, cell suffused with saffron-yellow, distal border twice as 
broadly black, more sharply defined. Hindwing brilliant orange-coloured instead of yellow-green. Of the $ 
there are 2 forms, one above white and the other, which is rarer, yellow (flavescens Bibbe). — corinna 
Wall, is a distinct local form from Waigeu, with the hindwing similar to cycinna, only somewhat darker 
orange on the under surface. $ white, beneath with deep black, broader, distal border. Forewing beneath 
white, with the cell dusted over with greenish. Hindwing with dark yellow basal area, which in $-form 
hastia form, nov., from Kayumera Bay, Dutch New Guinea, is light lemon-yellow and the upper surface 
of the wings is darker scaled. 
S. giscofy Gr.-Sm., a species from the Solomon Islands which is unknown to me in nature, is said 
to he similar above to the $ of panda from Java. 
28. Genus: Udaiana Dist. 
This genus forms a transition from Appias to Huphina in the absence of the ventral tufts of hair 
in the $$, but differs from both in the position of the second subcostal vein, which as in Parelodina 
arises quite near the apex of the cell of the forewing. Only one species is known, which inhabits Macro- 
malayana with the exception of Java and only occurs in the plains. The <$<3 occasionally settle on moist 
places in the forset-paths, the $$ were observed on a green climbing plant. According to Martin they 
are found in Sumatra only in woods where the soil is red, never in those where it is black. 
U. cynis Hew. (62 c). The under surface is likewise white, the apex of the forewing dusted with 
greenish yellow, costal margin of the hindwing bordered with yellow, base with some green scales. A very 
light $-form, which in its extreme has scarcely darker margins than the J, Hagen has named androides. 
Malay Peninsula, North-East and West Sumatra. — pryeri Dist. (62 c) is a darker local form from Borneo, 
characterised by the more deeply incised black distal border of the forewing and by the basal area of the 
hindwing beneath being always broadly scaled with green. North Borneo, rather rare. 
Additions and Corrections. 
P. 125: D. hyparete aurago Snellen, described from Billiton in the Tijdschr. o. Entom. 33, p. 303, 
bears gold-yellow submarginal patches on the hindwing beneath and hence approaches hypopelia Hag. and 
jataka Fruhst. 
P. 126: D. agostina orita subsp. nov. Forms a transition from annamitica Fruhst. to infumataFruhst. 
and differs from the Annam race in the darker upper surface of the forewing, which is somewhat lighter 
than in infumata and bears much smaller white submarginal spots than in annamitica, hindwing as in 
annamitica, only somewhat more densely dusted with grey. Locality Tonkin; apparently very local and 
rare, as I did not myself observe it. 
P. 130: D. diva B. & J., preoccupied by diva Fruhst. 1899, must be replaced by sagessa nom. nov. 
P. 132: D. belladonna formosana Mats., described in the Ent. Zeitschrift Stuttgart 1909, p. 92, 
approaches lativitta Leech in the markings, but differs from it in that the white distal spots of the fore¬ 
wing are not united with the proximal ‘ones and the hindwing above is almost entirely whitish at the 
inner margin, with light anal yellow dusting. All the spots small, but distinct. Formosa, Horisha. 
P. 140: Line 12 from above read ajanta instead of ajuta. 
P. 142: Under Huphina nadina eunama Fruhst. an intermediate form should be mentioned, koan- 
nania Mats. (Ent. Zeitschr. Stuttg. 1909, p. 88), with grey instead of green-yellow under surface. Kan- 
schirei and Horisha on Formosa. 
P. 149: Under Appias lyncida formosana Wall. Matsumura has described a $-form as tsurui, 
which according to the description belongs to a dry-season form and was collected on December 1 at the 
east coast of Formosa. — yayeyamana Mats., from the Loo Choo Islands, appears to be a local race of 
lyncida and was described from a with an expanse of 5 —9 mm. (should probably read 50—60 mm). 
P. 166: Terias libythea punctatissima Mats, is somewhat larger than the Malayan forms of the 
species, $ very pale, and occurring according to my examples in two phases, either with narrow black 
margin to the hindwing above or with this more extended, reaching the anal angle. Formosa. 
P. 182: Under Saletara panda Matsumura mentions a form kawakamii, from Ivatosho, an island 
close to Formosa, with lemon-yellow which is said to be spotted like nathalia. A very interesting dis¬ 
covery, unless the form is a $ of Appias albina.
