Sept. 28, 1915.—In the Shagamu district down to Ikorodu 
(W. of Epe and Oni) I saw lots of the Matabele ants [ Mega- 
ponera|, always with the same prey. They are very 
abundant round there and are called by the natives 
(Yorubas) “Jamjogu” (syllables all of equal length), 
which signifies “fighting”? or “ warlike.’ I had no 
opportunity of getting at their nests. I got a few more 
specimens.

Santschi. 
[Material :—A long series of $9, varying, although not 
ereatly, in size, taken May 25, 1915, from a nest in an old 
Termitarium in the decayed base of a large tree. It is 
probable, although not certain, that the tree was the one 
referred to below as cut down on May 28. For the relation 
of this form to Lycaenidae see the notes on Catochrysops 
phasma (p. 392) and on Lachnocnema bibulus (p. 388). The 
5 ant attending a pupa of this last Lycaenid came from the 
same nest as the above-mentioned series. ] 
May 28, 1915.—We have been having rather heavy rains 
to date. My last piece of entomological news relates to 
ants again. To-day a large tree was felled here, and in the 
decayed base of it was a nest of what I take to be Campo- 
notus maculatus, var. melanocnemis. I failed to find the 
queen, but I got larvae in all stages as well as pupae, the 
latter being in pale flesh-coloured cocoons of very thin 
texture. I will send you, this mail, specimens of larvae 
and cocoons as well as soldiers and workers. What puzzles 
me is, that last year we had an extraordinary flight of winged 
forms which Dr. Lamborn took to be of this variety. They 
were very large insects. A few winged forms came from 
prematurely ruptured cocoons to-day and they are quite 
small. However, I have secured a large number of pupae, 
larvae and adult forms, which I have put into a box with 
wood from the same tree—in fact, the portion where the 
nest was, which had been previously tunnelled by Termites— 
and they appear quite at home. All the pupae and larvae 
are stowed away out of sight, and the adults are now gorging 
themselves with sugar at eleven-and-six per stone. pie 
ought to do well.
