well as material received in the past from the late Dr. Roland Trimen, 

 collected in the Transvaal. The study of this shows that there are 

 either a number of closely related forms which have not been hitherto 

 discriminated or that the species are remarkably variable. This is not, 

 however, the place to take up the discussion of this subject.

The American Museum Congo Expedition brought back two males, 

 neither very well preserved, which represent this species. We have in the 

 Carnegie Museum fifty-five males and ten females, including the type 

 of the species. The two specimens taken at Medje in July and August 

 have been compared with these and they agree absolutely. 



The writer has a suspicion that L. lima H. H. Druce (Proc. Zool. 

 Soc. London, 1910, p. 368, PI. xxxiv, fig. 5) is only a slight varietal 

 form of this species, and that L. magna Aurivillius may only be an albinic 

 female of the same insect. In fact, he has a specimen of a female in 

 which the yellow color of the upper side is so pale that it might almost be 

 termed white and which seems rather closely to agree with the descrip- 

 ion given by Dr. Aurivillius.

There are two somewhat imperfect male specimens of this pretty 

 species taken at Medje, one in June, the other in August. As the author 

 points out, the species is near to D. eleala Hewitson, from which, how- 

 ever, upon comparison it may be distinguished at a glance by the 

 heavenly ultramarine blue of the upper surface, which strongly contrasts 

 with the greenish blue ground-color of its ally, by the almost complete 

 obsolescence of the lobe-spot on the under side of the hind wing, and by 

 the much reduced width of the transverse lines on the under side of 

 both wings.

 markings near the anal angle of the secondaries less prominent. On the under side
