43. Tbbias bbigitta Cram. 



Wet form. Salisbury, 6th March ; 2nd, Srd, and 6th April, 1898. 

 Dry form. Salisbury, 14th, 19th, and 22nd May, 1898. 

 I was pleased to receive a male of the dry-season form, which 

 seems to be much rarer than the wet-season male. 



44. Tbkias hapale Mab. 



c? . Wet-season form. Salisbury, 16th February, 1898. 



A second male (indicated as a var, in the direction of jioricola) 

 was obtained on the 11th May ! This seems to indicate that the 

 wet phase may sometimes occur in the dry season. 



S . Intermediate form. Salisbury, 30th March, 1898. 



S . Drijform. Salisbury, 4th, 17th, and 20th April, 1898. 



Mr. Marshall writes : — " Tou will notice among the Terias that 

 I have pointed out that T. cethioinca and butleri of Trimen are 

 respectively dry and wet forms of the same species, and thus, 

 taking the synonymy given in your revision, Impale must fall as a 

 seasonal form of senegalensis. I have not actually proved the case 

 by breeding, but I think you can take my observations on trust 

 now." 



Unfortunately Mr. Marshall's dates (upon the specimens for- 

 warded) seem to point to a different conclusion ; for he sends 

 wet, intermediate, and diy examples of true T. 1iaiKile=cethiopica, 



with the signs ^ •, ^ ■, (7) on their labels, and taken in February, 



March, and April respectively. Of T. senegalensis ( = butleri)h.e also 

 sends wet forms taken from February to March and intermediate 

 to dry forms obtained in March and April. Therefoi-e, although 

 T. Jioricola and T. Impale may prove to be only variations of the 

 heavily-bordered species, analogous to the narrow-bordered vari- 

 ations of T. suasa, there is, at present, no proof that such is the 

 case, and it certainly is not correct to call T. hapale the dry form 

 of T. senegalensis, because each of these types has its proper 

 seasonal phases. 



45. Terias senegalensis Boisd. 



Wet form. cT c? , $ , Salisbury, 16th February, 6th and 16th 

 March, $ 3rd April. 



Intermediate to dry. Salisbury, 6th and 13th March, and 2nd to 

 3rd April. 



The extreme dry form was not forwarded : it is represented by 

 T. bisinuata.
