model being nanna, while in reality it was phyllis, for by the 

 condition of the specimens it was probable that phyllis was 

 going over, and it was well known that H. erato phyllis was 

 always abundant wherever it occurred. Nanna, reaching so 

 far north as Pernambuco, was of special interest, and from 

 the four specimens fairly constant, only one showing a hori- 

 zontal red streak below the yellow transverse hind-wing, 

 band.

A NEW FORM OF PsEUDACRAEA POGGEI, DEW., MIMICKING 

 THE DORIPPUS, KlUG, FORM OF DaNAIDA CHRYSIPPUS, L., IN 



ex-German East Africa. — Prof. Poulton said thai he had 

 recently received four letters and three consignments from 

 ('apt. G. D. H. Carpenter, who had written from Lulanguru 

 on the Central Railway, 17 miles W. of Tabora, at a height 

 of 3766 ft. From these letters he had arranged the following 

 communications, of which each section bore the date of the 

 letter to which it belonged. 



Nov. 5, 1917. — ■" I have had a piece of stupendous hick and 

 hasten to tell you. A few days ago, on the small kopje of 

 granite behind the camp, about 300 ft. high, I caught what 

 I took to be, at first, a couple of Hypolimnas misippus, L., 

 the $ variety [inaria, Cram.] without apical black and white 

 markings. When I had caught them 1 thought they looked 

 a little odd, but as I have not caught a large number of 

 misi ppus and have not handled it much, and it's some time 

 since I caught one, I thought I must have forgotten the 

 details of its appearance, and put the specimens away for a 

 time. (Can you guess what's coming?) Next day I caught 

 a female of the type and felt quite sure then that I had go1 

 Pseudacraea poggei, Dew., and it was soon certain when I 

 caught a genuine misippus form inaria and then a male 

 poggei. I am now sending you, by registered post, in a 

 chocolate box by themselves these most exciting specimens — 

 three of the type and two of the variety, together with the 

 inaria.
