the river banks of the Wampoe near Kampong Inei and Stabat, 

 and is found in company with Danais hegesippns, 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 (Danisepa) diocletianus, Fabricius. 



Grose Smith as rhadamanthus. Snellen as radamanthus [sic], and 

 rhadamanthus, Hagen as diochtianus [sic], and rhadamanthus, Hors- 

 field [sic]. Staudinger as rhadamanthus. Distant. Moore. Mr. Moore 

 has recently shewn that Fabricius described " Papilio " diocletianus 

 from a female, and " Papil to" 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 Eurlpus halitherses, Doubleday 

 and Hewitson. 



37. *Ecpl(ea (Selinda) eleitsina, Cramer. 



Snellen records a single male from Sumatra. But for this solitary 

 identification the species has always been considered to be confined to 

 Java. 



38. Eupl(ea (Salpinx) leucostictos, Gmelin. 



Grose Smith as novarce. Hagen as novarce. Butler as vestigiata. 

 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 Euplcea 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, 

 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 

 Euplceas in Sumatra, both the brown and blue ones, even the rare 

 E. leucostictos, are exceedingly fond of spots where there is shade from
