X2o9) 1. Eurs^hura achlys (Hopffer) 



Harma achlys Hoiffer, 1862, Peters, Reise n. Mossambique, Ins., p. 390, PI. xxii, 

 figs. 5, 6. 



There is one female, taken at Niangara in November^ which agrees 

 well with the figure given by Hopffer, and with specimens in my collec- 

 tion from Zanzibar. 



(260) 2. Euryphura chalcis (Felder) 

 Harma chalcis Felder, 1860, Wien. Ent. Monatschr., IV, p. 234. 



Euryphura chalcis AvRi\ihi,ivs, 1912, Seitz, Gross-Schmett., XIII, p. 157, PI. xxxvic?. 



To tjiis species I refer four males and an aberrant female. One 

 male and the female were taken at Medje in August, the other three 

 males were captured at Niangara in November. 



(261) 3. Euryphura plautilla albofasciata Staudinger 

 Euryphura albofasciata Staudinger, 1896, Iris, IX, p. 213. 



I refer to this form a single female taken at Bafwabaka, January 7, 

 1910. It agrees quite thoroughly with the descrijation given by Staud- 

 inger. 



Cymothoe Hiibner 

 The genus Cymothoe is characteristic of the hot, wooded lands of the 

 Ethiopian subregion, to which it is confined. It offers a number of diifi- 

 culties to the student because of the great dissimilarity of the sexes in 

 . most of the species and the further fact that many species in the female 

 sex are known to be polymorphic. Until the test of breeding the various 

 species shall have been made, there will necessarily remain a measure of 

 uncertaint}^ as to the true relationship of various forms, some of which 

 have been alreadj^ named and described in one or the other sex and some 

 of which prudent students have been holding in the hope of obtaining 

 more light. 



The genus is rich in species, some of which are among the most 

 beautiful insects found in the region thej'' inhabit. The American 

 Museum Congo Expedition returned good series of a number of the com- 

 moner forms and. in addition, three species which I believe liitherto 

 undescribed, the males of C. angulifascia Aurivillius and of C. aramis 

 (Hewitson), of which hitherto only the females have been known, and 

 other material which helps to confirm conclusions, already reached by 

 the writer with the help of collections made for him in other parts of 

 the general region, which in some respects are at variance with the pub-
