1920] Holland, Lepidoptera of the Congo 223 



There is one female specimen in moderately good condition, taken 

 at Medje, July 20, 1910. As this sex of the insect has never heretofore 

 been descriljed, unless, as Aurivillius suggests, 0. melanomitra Karsch 

 be it, I venture to briefly gives its characteristics. 



9 . On the under side apparently agreeing completely with the description and 

 figure given by Dewitz {loc. cit.). On the upper side the ground-color is gray laved 

 witli lilac, especially on the cells and discal areas of both wings. The costa and outer 

 margin of the front wings are darker, and on the hind wings there is just below the 

 upper angle a dark spot or band of limited size, which is darker than the rest of the 

 wing. The lower end of the hind wing is broadly white on this side, with the three 

 marginal spots standing out conspicuously upon the light ground. On the under 

 side the anal angle and the adjacent parts of the wing are somewhat broadly laved 

 with yellow, which is also the case in the male.

There are eighteen males and one female of this insect, all in more or 

 less damaged condition, as is usually the case with them when received 

 from collectors. It appears to be almost impossible to preserve the long 

 narrow tails with which the hind wings of the species of this genus are 

 adorned. I have himdreds of them, and none seem to be absolutely 

 perfect. All of the specimens returned by the expedition were taken at 

 Medje on dates ranging from March to September, except two, one of 

 which was caught at Risimu in September 1909. and the other at 

 Gamangui on June 14, 1910.

There are four damaged specimens of this species all captured at 

 Medje, one in April, the other three in July.

This is indeed a very dubious species, as its name implies. It is 

 probably onh^ a seasonal variety, or local race of H. lebona Hewitson, 

 characterized by being a somewhat brighter blue on the upper side of the 

 fore wings, and having a wider inward extension toward the cell of the 

 light color of the inner margin. It is a very common insect in Cameroon 

 and on the Ogove River, and I have hundreds of specimens, both males
