R. elcia Hew. (146 Bg) is very similar to drasmos with the same scent-spot of the rj, being elcia. 
circular, bent around the bases of the median branches; but the under surface is more greyisli-brown, the 
postmedian transverse stripe on both wings distinct and between it and the margin another- almost just as 
distinct submarginal stripe which is absent in tarn. The $ is on both sides lighter, and the greenish-blue reflection 
above is just as extensive as in the <$. Philippines (Polillo in Luzon).

discal spot. — We figure a race from Java, abusina Fruhst. (160 d), which differs from Sumatran specimens abusina.

R. kessuma Hsf. (160 g, 146 h). This lepidopteron deviates still more from its allies than abnormis. kessuma. 
The under surface has 4 parallel oblique chains of white streaks. As the $ is also above lighter blue with a 
narrow dark distal margin, the exterior of a Lampides is produced. Only the $ shows yet dark forewings, 
the blue colouring being confined to the hindmarginal portion. Beneath, however, it resembles the though 
the ground-colom* is darker. Typical kessuma occur in Java. — deliochus Hew. (146 B d), from Rangoon; delioclius.

established for it. The scent-spot of the <$ is absent, the antennae are shorter, but the palpi are much longer 
than in most of the other <$<$ of Rapala, above black, the basal and discal portions of the wings with a violet 
gloss; $ violettish lilac, the black distal margin and costal margin being 3 to 4 mm broad. Under surface 
of a beautiful reddish yellow or cinnamon-brown colour; the transverse bands are not very prominent, 
but they are recognizable by rows of small fine whitish hooks forming chains particularly on the hindwing. 
Similar small white hook-spots are also scattered in the disc of the hindwing. Sikkim to Burma; rare. 
R. todara Mr. This species was hitherto only taken near Coonoor in the Nilgiris (above Metupalayan). todara. 
Somewhat smaller than distorta ; <$ above dark violettish-brown, basal part of forewing with a dull violettish - 
blue gloss; hindwing quite brown. $ similar to the preceding species, but above more blue than lilac. Under 
surface similar to distorta , but the small white lunae are better arranged, not so scattered. — Although I lived 
in Coonoor for some weeks, I did not discover this species; it is apparently either very rare or its flying season 
is very much confined. 
Note: Another species of the Zinaspa- group, zcina Nic.. has been described from the north (from China). Th eZinaspa- 
group represents the transition of Rapala to the rather closely allied Thecla and Surendra. This is most distinctly proved by 
the larvae: the larva of Z. todara is said to be extremely similar to that of Sur. quercetorum, the pupae of the two species 
not at all discernible. 
84. Genus: Poritia Mr. 
This genus is so very singular that it might be opposed as a separate division to the Lycaenini, Theclini, 
and Chrysophanini. Already the first observers (Marshall, de Niceville), who knew the live insects, stated 
the peculiarity of the lustrous colours producing the impression of American Erycinidae. I should like to add 
to this comparison, that the Poritia presumably represent the very youngest offspring of the Lycaenid family, 
and thus perhaps the most recent group of the palearctic butterflies. It seems that all the Poritia are rather 
rare insects, living very well concealed, with relatively very few specimens. When Kirby’s Catalogue was 
published, only the typical species was known; in the ,,Supplement" to it already 10 forms were mentioned, 
and to-day almost 50 are known. But nevertheless numerous large consignments from their patria arrive 
here without containing a single specimen of Poritia. Even large collections are greatly pleased to own a few 
species of this genus in scarce specimens. 
The chief centre of the range of the genus comprises the Peninsula of Malacca, Sumatra, and Borneo, 
each with about 10 species known. To the east two reach yet the Philippines, to the west no species goes as 
far as Ceylon. The insects presumably fly very early in the morning, when they sometimes come down 
and settle on low leaves; where they stay during the day I am unable to state. 
What Fruhstorfer mentions as a peculiarity for the whole Theclini, proves correct above all in the 
Poritia, for whilst the structural differences can hardly be used for the separation of the genus, the habitus
