a riche pale blue, the submarginal dots white and more prominent than in cyanifera. Median band on under surface of 
hindwing sharply defined clistally. Hagen reports this subspecies to be the commonest among the 6 Neptididi occur¬ 
ring on Astrolabe Bay, German New Guinea. — glyceria Fruhst. (126d) has both median bands very much broader glyceria. 
than grimberta, almost as broad as in obiana Sw., but distally only faintly bordered with blue. Subapical and all 
other spots greatly reduced. Subbasal band on under surface of hindwing considerably broader anally, more 
so than in the New Guinean form of venilia. Fergusson, d’Entrecasteaux Islands. — moorei Macl. (126 d), moorei. 
a very distinct local form distinguished by the fact that the median band on forewing is reduced to a large, 
roundish discal spot, by the almost completely diffuse dash on the submedian, and the short median band on 
hindwing which strongly tapers costally. On the hindwing the submarginal spots are greatly reduced as is 
also the dark violet distal irroration along the median bands. Cape York, North Australia. — glaucia Fruhst. glaucia. 
In size as well as in the rounded shape of wings approaching moorei, but subapical spots and especially also the 
median patches on forewing considerably larger, the latter much broader anally, margined with pale blue. 
Discal spot on hindwing resembling that of glyceria, but shorter, costally very broad, well rounded, tapering 
towards the back, the blue distal bordering just as heavy as in grimberta. Submarginal spots elongate and nar¬ 
row on both wings, above united into a delicate, lovely pale blue band not again met with in any other sub¬ 
species of venilia. Underneath all the white spots are most sharply defined, clear white with a lovely, delicate blue 
iridescence. Not a trace of white scaling on distal border. Cellular dots on forewing as well as submarginal 
spots on hindwing of a darker blue than in any other form of venilia. Neu-Mecklenburg. — neohartnoverasia neohannove- 
Pagenst. Very much like glaucia, but the bordering of median bands violet instead of blue, the submarginal ' aruJt 
spots not united into a band. Neu-Hannover, types in the Tring Museum. 
Genus: Jfeptis F. 
Costal vein inosculates in <$ into costal margin, in $ into distal margin. The second subcostal nervule 
arises before the end of the cell. Comprising about 60 species, it is one of the largest genera of Southern 
Asia. 
Group A: Neptis. 
N. hylas is the oldest name of the species well known under the name of aceris, leucothoe and eury- 
nome, and at the same time the first name given any Neptis. Nevertheless it was neglected until in 1907 and 1908 
I reestablished its priority, and in my treatise on Neptidi (Stettiner Entomologische Zeitung 1908) referred 
also the other until then partly misplaced subspecies to this species. Being represented by about 30 described 
subspecies, local or insular forms, N. hylas appears as one of the most variable species found in the Tropics 
and Subtropics of the East; being represented, although as a great rarity, even in the Palaearctic Region, 
its range of distribution is enormous, comprising the entire Palaearctic-Asiatic and Indo-Malayan Regions, 
from Germany as far as Japan and southward to the Smaller Sunda Islands. Characteristic of the entire spe¬ 
cies is the black border of the main band on the under surface of the hindwing, which surrounds both the costal 
and anal margins and not infrequently also accompanies the submarginal band; its greatest development is 
found in a few Indian forms and that from Sumatra, whereas in specimens of the extreme dry-season or in the 
forms found on islands with predominating arid character (islands of the Timor Group), as well as in the northern 
races (f. i. the Japanese N. hylas intermedia and its local or seasonal varieties), this black border is partially 
obsolete. Going from North to South we encounter the following forms: yessonensis subsp. nov., recently sent yessonensis. 
to me by Prof. Matsu Mr ra, differs from intermedia Pryer from the main island of Hondo in the more rounded 
outline of wings; in si£e it stands midway between the fall-brood passerculus Fruhst. and intermedia Pryer passerculus. 
(Vol. I, p. 176, pi. 53 d)- The white markings are of much greater extent than in the Hondo form, especially mtermcdla - 
the subapical and intramedian spots are much more developed. The submarginal band on the hindwing is, 
corresponding to the more rounded contour of the wings, more strongly curved, the under surface darker 
red-brown than in intermedia, and the second (subbasal) white curved band is on account of its greater length 
more prominent. Sapporo, Yesso. luculentaFra/i-sf. (126e) is the largest among all known forms. Specimens luculenta. 
from Ishigaki and Formosa differ somewhat from Chinese and Tonkinese specimens in having on both wings 
the white bands rather narrower, and on the under surface of hindwing the submedian band nearly always 
black, hardly ever white. Quite abundant in Okinawa, Ishigaki (type) and the low-lands of Formosa. — 
hylas L. (Vol. I, p. 174, pi. 53 d) occurring throughout Southern and Indo-China in the following forms hylas. 
described already in Vol. I, p. 174: sangaiea Moore, probably the spring-brood, of very small size, flying from sangaica. 
December until May, most abundant in March and April. Hongkong. — fa. acerides Fruhst. from South and acerides. 
West China, collected by me in November at Hongkong. In Tonkin, Annam and Siam acerides is very common, 
the majority of specimens differing nowise from Chinese ones, although we meet occasionally specimens leading 
over to the Indian forms. The sexual organs of the hitherto mentioned and also of the European forms of hylas 
completely agree in every detail. Tegumen delicate, uncus slender and sharp pointed, somewhat broader in the
