48. Teeacolus ANTIGONE Boisd. 



Intermediate and dry forms. S 6 ■, 9- ■, Salisbury, 19th and 22nd 

 May ; 5th and 18th June, 1898. 



Mr. Marshall labelled two females of T. {thonus (var. hyperides) 



as "T. 2Megetonia^'=antiyone: one example of the intermediate 



form is labelled with the wet sign ^ , but was taken on the same 



day as another marked ^ , and differs from the true wet form in 



the total absence of the bright lemon-yellow at the base of the 

 primaries on the under surface and the reddish tint of the 

 secondaries ; this must, therefore, have been a lapsus, for it is not 

 likely that wet, intermediate, and dry forms (in equal condition) 

 would all be flying within less than a week of each other. The 

 single female obtained, though taken on the 5th June, belongs to 

 the intermediate phase.

Dry form. cJ , Salisbury, 5fch June, 1898. 



The two males are labelled as T. achine (intermediate and dry) 

 and the two females as T. evagore-pJdegetonia (intermediate aud 

 dry). The male obtained in March is, however, the typical wet 

 form of T. ithonus (=Jiero c? ) ; the two females obtained in May 

 are the intermediate form of the same species ( = T. hyperides $ ) ; 

 and the male obtained in June is the dry form (=T. ignifer 6).

Mr. Marshall labels all the specimens as " T.pallene"; he writes 

 as follows : — " I am somewhat in doubt as to the Teracoli I have 

 sent you labelled pallene, for they are practically indistinguishable 

 from the extreme dry form of ompJude ; yet the wet form is 

 certainly not omphale, which I do not remember ever to have seen 

 here, but seems referable to pallene. The larva is very similar to, 

 though distinct from, that of phlegetonia as observed by me in 

 Natal, but they are not distinguishable in the pupal stage. I 

 obtained some thirty eggs from marked females of '1 pallene, 

 intending to submit the moulting larvae to varying conditions in 

 order to ascertain the range of its specific variation : a large 

 number of eggs proved infertile and of the remainder all the larvae 

 died before they were half-grown — why 1 know not." 



I do not believe that T. ptallene occurs so far to the south as 

 Mashunaland ; but in none of its seasonal forms does it resemble 

 T. omphale ; indeed it belongs to the same section of the genus as 

 T, daira. The wet form of T. omphale may vary more than is at
