One butterfly and 7 moths from various localities were 

 presented by the Zoological Museum, Tring, Hertfordshire. 



A beautiful group of 4 similar butterflies belonging to 

 three Sub-Families from New Britain (1899) ^^^^ presented 

 by Col. C. Swinhoe, Hon, M.A., constituting a valuable 

 addition to that part of the Bionomic Series which illustrates 

 theories of Mimicry. Col. Swinhoe also presented 4 butter- 

 flies of the genus Acraea from S. and S.E. Africa (1899), 



A very interesting pair of insects was presented to the 

 Bionomic Series by H. Donisthorpe, Esq., viz. the TIpfniptf?rnn^(SJ»^^ 

 Lomechusa striivtosa and its host Formica mifu ^ both capturedsa^*^.t*v 

 in the neighbourhood of Roermond, Holland, by Father 

 Wasmann in 1897. 



A fine series of 93 butterflies from British East Africa 

 (Mombasa, Machakos, and Machakos Road), 1900, was pre- 

 sented by the captors, S. L. Hinde, Esq., and Mrs. Hinde. 

 The series included several interesting examples of seasonal 

 forms, including a most beautiful variety intermediate between 

 Precis octavia (wet season) and P. sesamiis (dry), of forms 

 showing the influence of local conditions, such as height above 

 the sea and dryness. There were also valuable groups of the 

 diff'erent varieties of the same species captured in less than an 

 hour on a patch of ground a few yards in extent. The 

 excellent condition of the specimens and the admirable data 

 accompanying them render the gift especially valuable to 

 the Hope Museum. 



Later in the year another valuable series of 113 specimens 

 from Machakos (June 6, 1900) and Kitui (Nov. and Dec.) was 

 presented by the same generous donors. The series included 

 a very interesting set of 68 Lepidoptera, almost exclusively 

 butterflies, caught in two hours at a single spot at Kitui, on 

 Dec. II. The group represents in a most interesting manner 

 a characteristic assemblage of Rhopalocera in this locality. 

 It contains several seasonal forms (wet) of butterflies of the 

 genus Precis and some interesting local varieties. There are 

 also species which are new to our collection, and others which 

 are almost wanting. Among the former one beautiful 

 Acraea, also absent from the British Museum, is conspicuous.
