Efiilen in Cameroon by Dr. A. C. Good. The female is polymorphic, and 

 at least four well-defined varieties in this sex are known. The commonest 

 is that named althea by Cramer. The prevalent color of this variety is 

 black, with the wings crossed by a white mesial band. Closely allied 

 to it is the form called euthalioides by Kirl)y, in which the white mesial 

 band is broader and more irregular than in althea. Our plate gives 

 accurate representations of the other two varieties to which reference 

 has been made and a verbal description is not called for. I take pleasure 

 in designating the single specimen obtained by the American Museum 

 Congo Expedition at Medje as the type of C. coenis form rubida, new 

 form, 9 , but have selected a more perfect specimen from my own col- 

 lection taken at Kangve for representation on the plate. I have many 

 ex larva. 



The specimens of C. canis brought back by the Expedition were 

 almost all taken at Medje from June to September 1910, but there are a 

 couple ticketted as taken at Gamangui in June, one is labelled as from 

 Munie Katoto, September 1909, a few from Avakubi caught in October 

 of that same year, and several from Niangara captured in November 

 1910.

Aurivillius in his 'Lepidoptera .^thiopica,' p. 21.5, makes C. {Harma) 

 altisidora (Hewitson) a synonym of C. adelina, regarding the former as 

 being the male of the latter, which has priority. In Seitz, Gross-Schmet- 

 terlinge, XIII, PI. xxxvrf, he depicts a male of the following species 

 as that sex of adelina, and also gives a figure of a female which certainly 

 does not conform to Hewitson's type of C adelina. However, this species 

 is wonderfully varial)le in the female sex, as I have pointed out. I am 

 convinced that Dr. Aurivillius is in error. I give on Plate VIII, fig. 9, 

 a representation of the true male of C. adelina (Hewitson) . It is an insect 

 closely allied to C. ccenis, from which it consistently differs in always 

 having the ground-color of the wings on the upper side deep Naples 

 yellow and not white or creamy white, as is the case with C. ccenis. 

 With some hundreds of C. ccenis before me as I write, and a good series 

 of C. adelina both males and females, the difference is plainly visible 

 and strikingly constant. The females of C. adelina are exceedingly 

 variable in the ground-color or tint of the wings, although the black spots
