446 L. de Niceville & Dr. L. Martin —Butterflies of Siimatra. [No. 3, 
preceding species in May and September in tbe same localities. All 
species of Oerydus and Paragerydus are shade-loving butterflies, and 
never venture into the direct rays of the sun. With the exception of 
the three common species, G, symethus , Cramer, G. biggsii, Distant, and 
P. horsfieldi , Moore, they are only found in deep forest, mostly restlessly 
flying round the buds of not very high bushes. They are rather 
weak on the wing, but disappear immediately in the forest if pur¬ 
sued. Both genera can be instantly distinguished by the struct are of 
the legs in both sexes, and both possess three or four minute whitish 
or ochreous spots on the costa of the forewing on the upperside. 
These are very prominent in P. psetus, de Niceville, and P. horsfieldi , 
Moore, less so in P. panormis , Elwes, and just visible only in P. portunus , 
de Niceville. 
295. Allotinus nivalis, Druce. 
Occurs throughout the year in forest near Selesseh, but is 
rather rare. 
296. Allotinus alkamah, Distant. 
Distant. Found from Namoe Oekor to the Central Plateau, but is 
always rare. I do not yet possess specimens of A. subviolaceus, Felder, 
from Java, to compare with Burmese, Malayan Peninsula and Sumatran 
specimens of A. alkamah. It is I think probable that the latter is only 
a synonym of the former. 
297. Allotinus apus, de Niceville. 
A. apus, de Niceville, Journ. Bomb. Nat. Hist. Soc., vol. x, p. 27, n. 11, pi. S, 
fig. 17 , female (1895). 
Two female specimens only have been obtained at Bekantschan in 
February, 1894. 
298. ^Allotinus major, Felder. 
Hagen. Originally described from Celebes. We have not seen any 
species from Sumatra agreeing with Felder’s description and figure. It 
is probable that Dr. Hagen identified A. apus, de Niceville, with this 
species, as superficially they are somewhat similar. 
299. Logania malayioa, Distant. 
Originally described from Sungei Ujong in the Malay Peninsula. 
300. Logania sriwa, Distant. 
Originally described from Malacca in the Malay Peninsula.
