caught a fine Pangonia [the o of a very striking new species] 

 feeding, hovering on the wing like a Bombyliid, from a Com- 

 posite flower. The specimen will be sent you; I think it's 

 not the same as the one which bit me" (Proc. Ent. Soc, 

 I '.»]<). p. lxxxii). Another Pangonia caught about the same 

 time is P. distincta, Ricardo, ?. 



" May 27, 1917. Itigi. 



" The operations in pursuit of a very elusive German force 

 in the neighbourhood are still in full swing. Some of the 

 ' W.A.F.F.s ' passed through here yesterday, and I saw a Hausa 

 for the first time. The commander of the force has been 

 taken prisoner, sick, but we have not had much success so 

 far, and the force still continues to run about, and gets lost, 

 and causes a lot of trouble. They cut our telegraph wire 

 this morning, and it is said they have put bombs on the 

 railway ! I am much less busy now, as (following the usual 

 custom !) quite a large staff has been sent up here, now that 

 the work is about half what I had to cope with without 

 qualified assistance a little while ago. 80 I have been able 

 to get out for a bit, but we are now having very fine dry and 

 (in early morning) cold weather, which is bad for butterflies. 

 I am cpiite fit and enjoy the 'cold mornings. 



" Pangonia is very common now, and I have caught 

 numbers of males. They often hover in the air exactly like 

 Svrphids (save that their long rostra are conspicuous), and 

 (with females sometimes) may be found on flowers. I caught 

 one male on a patch of white Labiate flowers, visiting flower 

 after flower, and putting his proboscis down each tube like 

 a bee ! There was a very curious Tabanid here a little while 

 ago, with proboscis relatively about as long as that ol Glossina, 

 a large blue-black fellow, with wings marked with brighl 

 brown, who never made any attempt to bite, but was only 

 found on flowers or hovering in the air. [This is the new 

 Pangonia feeding from a, Composite flower, v. supra. Three 

 females of another interesting Tabanid (Pangoniinae), 

 Dorcalaemus row pactus, Aust., taken Mar. 28, bore the note 

 that when flying their appearance and sound were very 

 bee-like.]
