THE BUTTERFLIES OF SIAM. 12S 



133. Ergolis specularia arca Fruhst. 

 Occurs in most districts, but is nowhere common. 



134. Penthema dahlisa mimetica Latliy. 

 Onl)- four examples of tliis butterfly are known. 



It was described, as Penthema mimetica, from a single female 

 which came from the neighbourhood of Korat, and which is now in the 

 Adams Collection in the British Museum. I have since taken three 

 other females — one at Hup Bon in April 1911, and two at Pak Jong in 

 January 1914. One of these specimens is now in the British Museum- 



On the upper side, the female of mimetica bears a most extra- 

 ordinary resemblance to the female of E. in. mulciber. The first time 

 I came across it I was completely deceived, and should have left it alone 

 as being mulciber had not its flight struck me as peculiar for that butter- 

 fly. On the second occasion I was again deceived, although I was 

 prepared for the resemblance. The third specimen was resting on the 

 ground with closed wings and the resesnblance was not so obvious. 



135. CcpiiA erymantuis lotis Sulz. 

 More or less common everywhere. 



136. Atella rnALANTOA PiiALANTHA Drury. 



A few specimens taken on the Petchaburi River in April, and 

 ftt Sriracha in September. 



137. Atella alcippk alcippoides Moore. 



This butterfly was quite common on the Petchaburi River in 

 April 1910, but I have seldom come across it since. 



138. Issoria siniia sinha KoUar. 

 Widely distributed, but not common. 



139. Cynthia erota erota Fabr. 



Males common in all forest areas, females rare. 



140. ClKKOCnHOA fasciata fasciata Fldr. 



Not uncommon in Bangkok, but apparently rare elsewhere. 

 The dry-season form is flavobrnnnea Sn. 



141. CiRROCllROA TYCUE MITFIILA Moore. 



Widely distributed and fairly common. 



142. CiREOCHROA SURTA SIAIIENSIS Fruhst. 



This butterfly is at present known only from Bangkok, where it 

 is rather scarce.
