A LIST OF BL'ITEEFLIES COLLECTED IN THE TAVOY 

 DISTRICT, BURIVIA.

{With a map and i^late). 



No systematic collecting appears to have been done in the Tavoy District 

 since Doherty's time and as I have now collected and received specimens for the 

 past ton yearp, a list of the species taken may be of interest to readers of this 

 journal. 



As far as possible I have given exact dates, localities and altitudes of capture. 



When Doherty \'isited the district in the eighties there must have been little 

 or no communication with the interior, but now there are several good graded 

 roads, suitable for motor traffic, so that travelling is rapid and comfortable. The 

 accompamdng map shows all the good collecting grounds, so far as T am aware 

 of and the roads on which cars can be used. This list does not claim to be a 

 complete one, and only shows the forms that have been received or taken by me. 



It will be noticed that most of the collecting was done on hill-tops, and 1 

 should advise any one wishing to try Tavoy to keep to this, as on the plains 

 Httlc i3 to be seen and those mostly of the commonest species. The best collect- 

 ing grounds are fairly open hill-tops, with evergreen forest, where the sunlight 

 can filter through the foliage, and the best hours for catching are from 11 a.m. 

 to 5 P.M. 



These hill tops appear to be general meeting grounds and are frequented 

 by large numbers of butterflies, many of which appear to fly about 

 in an aimless nranner, while others of a fighting nature, seem to come there 

 with the sole object of attacking every butterfly that happens to pass within a 

 limited distance of their resting spots. 



The best seasons for collecting are from October to exid of December and from 

 the middle of February to end of May. Between June and September it is not 

 possible to do much owing to the heavy rain and the flooded state of the country. 

 In naming the species I have followed Colonel Evans' list of Indian Butterflies, 

 which was published in Vol.XXT of the Society's Journal. I am greatly indebted 

 to jNIr. W. S. Wood, of the Bombay Burma Trading Corporation, Ltd., for the 

 help he has rendered me and to whose knowledge of the country is due the 

 little success I have gained. He also personally collected a large number of 

 specimens including many of the rarities shown in this list. 



To Colonel W. H. Evans, D.S.O., R.E., I am also much indebted for the help 

 he has given me by identifying a large number of specimens —a task by no msans 

 light.
