520 Rev, K. St. Aiibyn Rogers' Bionomic. Notes mi 



Now althougli I have usually found F. trimenii a rare 

 species, this is not the case at Rabai. In fact, in some 

 seasons it is more common than any other member of the 

 group with the single exception of A. natalica. It 

 frequents much the same situations as the Acra^as but its 

 flight is more lofty and sustained, and when alarmed it 

 goes off at a great rate. Still the integuments of the 

 thorax are very tough and quite different from those of 

 species which adopt a protective (cryptic) appearance. 

 Although the specimens of trimenii from British East 

 Africa differ in some details from the South African type, 

 still they always have the brilliant piidc and jiearly white 

 under side which at once distinguishes them from the 

 nearly allied P, hoisduvali, Doubl., in which the corre- 

 sponding surface is ochreous. 



[Tavcta, July 5, 1905. 



Abantis tettensis, Hopff,, mimicking on the under surface 

 and at rest the pattern of the smallest Acr*as of the 

 doiiblcdayi type, was quite common here in the rains in 

 one place. It flies backwards and forwards with great 

 rapidity quite in the usual skipper manner, and always 

 settles with wings half-raised, so that it gives no idea of an 

 Acrma on the wing or during the brief pauses between 

 successive flights.]

This group of large Acrpeas also includes Acriea chilo, 

 Godm., captured by Rev. St. Aubyn Rogers in several 

 localities. A. astrigcra, Butl., not in his collection, but 

 sent to me by Mr. and Mrs. S. L. Hinde from Fort Hall 

 and Kitui, must also be regarded as a member, although 

 apparently much rarer than any of the others. The group 

 is furthermore perhaps united by its smallest members, 

 A. pharsalus and small individuals of A. natalica, with the 

 still smaller species, — acrita, Hewits., Ir/vsia. Godm., doulle- 

 dayi, Guer., and neohule, Doubl. The following table 

 shows the numbers of specimens (with the inclusive dates) 

 at Oxford captured by Mr. St. Aubyn Rogers at various 

 localities in British East Africa.
