IL The female of Planema macar is ta and the female of PI. 
alcinoe with their mimics the car?nentis form of the female Acrœa 
jodutta, a form of the female of A. althojjft, and the female of 
Pseudacrœa hobleyi. The rare female A. altliojfi is probably a 
secondary mimic of the abundant female A. jodutta , rather than 
of the primary Planema models, while another female form of 
althojfi with yellowish markings appears to mimic the male 
jodutta. 
III. Both sexes of Planema tellus with their mimics ' a female 
form of Acrœa jodutta, a female form of A. althojfi , both sexes of 
Pseudacrœa terra , and the female form niobe of Papilio dardanus 
dardanus. The female form of A. jodutta exhibits a very well- 
marked dimorphism at Entebbe and both forms are abundant. In 
this combination as well as in II it is probable that the female 
jodutta is the model lor the female A. althojfi. Dr. Karl Jordan’s 
opinion, that Pseudacrœa hobleyi , Ps. terra and Ps. obscura are all 
forms of a single species, was confirmed by Mr. Wiggins, who 
captured transitional specimens on August 14th and Septem¬ 
ber 24th. He also took a few female A. jodutta combining the pat¬ 
terns of the two mimetic forms. 
Mr. Wiggins has greatly extended his accurate observation of 
these interesting combinations in the year 1910, and has also, in 
both 1909 and 1910, studied the associations that are grouped round 
Danaine models, round the black-and-red Acrœas, and round the 
highly protected genus Aletis. (Vol. II, Mémoires, p. 483.)
