are labelled as having been captured in April, the rest were taken at 

 dates ranging from July 8 to September 24, 1910. If collecting went 

 on continuously at Medje this fact would indicate that there ma}' be 

 two broods annually. 



There is some variation in the coloring of the upper side of the wings, 

 a few specimens having a purplish tint contrasting with the purer blue 

 of the markings of most of the specimens, and the white spots beyond 

 the end of the cell of the fore wing in an occasional specimen are suffused 

 with blue almost throughout their extent. 



The two females in the collection belong to the form to which 

 Suffert has applied the name H. cissalma, characterized by having the 

 white of the paler spots replaced by yellow. The collection contains 

 no males corresponding to the form cissalma in that sex, which Suffer! 

 describes as having all the lighter markings on the upper side, except 

 the subapical spots, blue throughout.

This species, which has been by some authors regarded as a varietal 

 form of the preceding but which is quite distinct, is represented in the 

 collection by twenty-one males and one female. They all were taken at 

 Medje, except one male which is ticketted "Niangara, November 14- 

 16, 1910." Three of the males taken at Medje were captured in April, 

 all of the other specimens bear dates ranging from July 8 to September 

 27, 1910. Like the preceding species, this probably has at least two 

 annual broods.

This species is represented in the collection by a single male, which 

 does not differ at all from specimens in the collection of the writer from 

 the southern parts of Cameroon. It was taken at Bafwaboli, Nov- 

 ember 11, 1909.
