wahlhergi I have only taken in the same district, i. e. on 

 the Coast hills. H. deceptoi' is not uncommon, but it is 

 very difficult to get in good condition.] 



{^Rahai, May 1, 1906. The first specimen of H. deceptor 

 I ever captured was settled with its wings hanging down 

 just like ochlea, bat I have never observed this since and I 

 have seen dozens of the species. It is very fond of settling 

 on the outer leaves of small trees and chasing its com- 

 panions from time to time, and on the wing is not at all 

 unlike H. misijjjms.] 



[Buralia kirhyi is included in the observations on E. 

 deceptor recorded in the above extracts from two letters. 

 The two species, which are extraordinarily alike, were not 

 at first discriminated. E. B. P.] 



[Bahai, May 9, 1908, I saw a good many Euralia decep- 

 tor and Idrhyi last Saturday, which was a fine day after 

 rains earlier in the week, but they were mostly in bad 

 condition and the better specimens were flying high. I 

 also caught two or three Buxanthe wakefieldi, but they 

 were none of them perfect, and I did not keep any.] 



Euxanthe tiherius, Gr.-Sm., $ (Plate XXVII, fig. 3). 

 The female of this species should also be included in the 

 combination, although the male is very distinct. It is 

 true, however, that the conspicuous fulvous patch on the 

 inner part of the fore-wing at once distinguishes the female 

 from all the other members, and is a prominent feature 

 even on the wing. The development of the white patch 

 on the hind-wings is the more striking because of its total 

 absence in the male. As a further mimetic modification 

 of the female, all the pale spots in the fore-wing are larger 

 and whiter than in the male. I am strongly of the 

 opinion that B. tiherius itself must be regarded as a pro- 

 tected species and a Miillerian mimic. Unless thoroughly 

 disturbed, it is a very sluggish insect and is most con- 

 spicuous on the wing, especially in the deep shade which 

 it loves. It is true that the texture of the wings is much 

 softer and more readily torn than that of species like 

 A. niavius domiinicanus and ochlea, but the body is ex- 

 tremely tough, and I have found it exceedingly difficult to 

 kill by pressure between the finger and thumb, — even 

 more so than Banaida {Bimnas) chrysippus, L. 



\Rcd)ai, May 1, 1906. I have captured a fine Euxanthe 

 \E, tiherius\ which is quite new to me. This was a great 

 surprise, as I have worked this district pretty hard, and
