the river banks of the Wampoe near Kampong Inei and Stabat, 
and is fonnd in company with Banais hegesippus , Cramer, and Euplcea 
distantii , Moore, the Danainse of the lowest elevations For twelve 
years Dr. Martin did not succeed in obtaining a female, only in the last 
two years were females found in considerable numbers by the imported 
Lepcha collectors from India, but that sex is always much rarer than 
the male. 
36. Euplcea ( Banisepa) diocletianus, Fabricius. 
Grose Smith as rhadamanthus. Snellen as radamanthus [sic], and 
rhadamanthus. Hagen as diochtianus [sic], and rhadamanthus , Hors- 
field [sic]. Staudingef as rhadamanthus. Distant. Moore. Mr. Moore 
has recently shewn that Fabricius described “ Papilio ” diocletianus 
from a female, and “ Papilio ” rhadamanthus from a male of the same 
species, so the earlier name applied to the species is here used irrespec¬ 
tive of the sex. Is rather a common species in the plains, and occurs in 
the outer hills as high as Bekantschan ; the female is always much 
rarer than the male. The male is mimicked by Papilio velutinus , Butler, 
and also by the first and second forms of Euripus halitherses, Doubleday 
and Hewitson.

Snellen records a single male from Sumatra. But for this solitary 
identification the species has always been considered to be confined to 
Java, 
38. Euplcea (Salpinx) leucostictos, Gmelin. 
Grose Smith as novaroe. Hagen as novarce. Butler as vesfigiata. 
Distant as vestigiata. Very rare in Sumatra, perhaps commoner in Java 
than elsewhere. I have during many years past added to my collection 
every specimen of this group of Euploea I could obtain, and now that I 
have very extensive material to compare, I find that it is quite impossible 
to separate E. leucostictos , described in 1789, E. dehaani , Lucas (1853), 
E. novarce , Felder (1862), E. vestigiata , Butler (1866), E. leucogonys y 
Butler (1879), and E. lazulina, Moore (1883). The species is obviously 
a variable one, the variations which it exhibits are not confined to parti¬ 
cular localities, but are shewn wherever it is found. Mr. Moore in Proc. 
Zool. Soc. Lond., 1883, restricts E. novarse to the Nicobar Isles and 
Tenasserim, E. vestigiata to Sumatra, E. lazulina to Malacca, E. leuco- 
gonys to Malacca, E. leucostictos to Java, and E. dehaani to Java. All 
Euploeas in Sumatra, both the brown and blue ones, even the rare 
E. leucostictos , are exceedingly fond of spots where there is shade from
