(ibid. I'M 7, p. 246) and Mr. Wheeler himself (ibid. 1917, 

 p. 166) have found both male and female taking the active 

 part. Mr. Hamm also saw, near Winchester (July 1896), a 

 male paired with the valesina female, and the latter, which 

 could not be mistaken, supported the former. More evidence 

 is required for all groups except the Pierinae. For these 

 Dr. Dixey's conclusion on p. clii, will meet with general 

 acceptance. In this group, indeed, the males appear to take 

 the active part even when smaller than the females.] 



Returning to the letter of Dec. 7 : " We have just heard 

 unofficially that von Lettow, the enemy commander, with 

 what forces are left him, has got across the Rovuma R. into 

 Portuguese East Africa. I'm not sure that it's good news, 

 although it now means that the country is free of Germans, 

 all the other bands having been accounted for. But the 

 affair won't be over till the gallant von Lettow is also 

 accounted for. He certainly is to be admired for his spirit. 

 " Dec. 9. — Sunday. Thundering and raining now and very 

 cool ! " 



The following account of Lulanguru, written for the Ento- 

 mological Society, was sent with the above letter of Dec. 7 : 



" This camp, 17 miles west of Tabora, is on the Central 

 Railway and also on the main road from Dar es Salaam to 

 Ujiji, along which countless slaves must have gone down to 

 the coast in old days, and up which Stanley may have come 

 to Ujiji. It lies in country which I am told by a Rhodesian 

 is much like parts of N. Rhodesia. It is flat, 1148 metres 

 above the sea, with scattered irregular low hills and kopjes 

 of granite. The bush is of the open kind with small, not 

 thorny, deciduous trees, now in full spring leaf, and the 

 grass is sprouting again, so that everywhere it is delightfully 

 green. We had about a week of quite heavy rain a little 

 while ago. 



"' My collecting ground here is on a kopje immediately 

 behind the camp, which seems to concentrate insects from 

 the surrounding flat country : at any rate, until I started 

 collecting on its summit I never found anything worth much. 

 " I will first go through the successive groups of butterflies 

 and then £jive a few notes on other Orders.
