marvellous thing that since I came here I haven't seen a 

 single Danaine of any kind whatever ! [A $ D. chrysippus, L., 

 of the type form was taken a little later, on Dec. 31.] 



" Acraeinae. — These have not proved to be plentiful : there 

 are one or two species that I never met until I had come a 

 good way south of the lake, and imagine they must be South 

 African forms. A. zetes, L., occurs in its typical Eastern form 

 [acara, Hew.] with yellow suffusion and very little black. 

 [The Lulanguru species was not acara, but anemosa (11) with 

 a single astriyera.\ It is thus more lovely than the forms I 

 met on the islands. I find it extremely shy and difficult to 

 approach — far more so than such an aposematic and tough 

 insect need be ! I am quite sure that the Eastern forms I 

 have met are far more difficult to catch than the island 

 specimens were. A. encedon, L., occurs — rather washy and 

 uncertain in colour. It annoys me because I have never 

 found its larvae, and yet one sees it in all kinds of country, 

 so it must feed on some universally distributed food-plant. 

 [The larvae feed on the water-plant Commelina,. " Sudd." 

 The Lulanguru collection contains — taken between Nov. 22 

 and Dec. 24 — 2 <$ $ and a $ and $ in cop. of the type form, 

 and 6 S 6* of the form daira, Godm. and Salv. Thus the 

 daira form was not nearly so predominant as in Capt. Lam- 

 born's collection made further east and north; Trans. Ent. 

 Soc, 1917, pp. 327, 328.] 



" Nymphalinae. — Charaxes abound on the kopje and several 

 forms are new to me. It is a wonderfully exciting spectacle 

 for an entomologist when these magnificent creatures chase 

 each other in the bright sun through the trees with their new 

 greenery. I saw one day a never-to-be-forgotten sight — two 

 species whose names I know not chasing each other, both in 

 perfect condition, one with the basal half of its wings sky 

 blue, the rest black [the ^ bohoiianni, Feld.], the other with 

 a broad border of rich terra-cotta to its velvety black wing3 

 [the $ azota, Hew.]. I put down rotten bananas as bait 

 (remembering Swynnerton's tip) and have taken about a 

 dozen different forms, though how many species I know not. 

 The above-mentioned blue one, in $, has a very conspicuous 

 white bar on the underside of the f.-w., which I am certain
