saw was a mass of wings, those of each Termite overlapping 

 another's, so that the appearance reminded one of a piece of 

 butterfly's wing seen under a microscope. They made no 

 attempt to fly away. After a while the mass began to elongate 

 in two directions, and two long lines, headed by workers and 

 soldiers, began to move away. But the Termites very soon 

 stopped and bunched together again. What a meal for a 

 Wagtail had there been one there. This species of Termite 

 comes to light in the evening in a very annoying way. I 

 send you some of them. 



" On Jan. 5th I found under bark of a dead tree a small 

 Carabid [Thyreopterus flavosignatus, Dej.J and several large 

 Erotylids [Mimodacne grandipennis, Fairm.], both species of 

 the same coloiir scheme — black, with two orange transverse 

 bars. By a very curious coincidence, only the night before 

 some insectivorous animal had been in my hut, and left a 

 dropping behind it in which I found an elytron of this 

 Erotylid, and wondered what beetle it was, as I had not 

 hitherto met with it. The Carabid is a small one, and the 

 other so very much larger that it is difficult to believe that 

 mimicry is at the bottom of the resemblance (unless the 

 Erotylid is distasteful and the Carabid a synaposeme). 



" On Jan. Sfh I caught a very remarkable-looking large 

 black fly with conspicuous red head. I caught it on the 

 wing — it flew very slowly — and settled conspicuously on a 

 leaf. 1 send it you — I cannot place it at all." 



The fly is Bromophila caffra, Macq., figured as one of a 

 Rhodesian group of insects in Trans. Ent. Soc, 1902, pi. xxiii, 

 fig. 27. Dr. Marshall speaks, on p. 531, of its abundance 

 and sluggishness, and states that "it ejects a yellow liquid 

 from the mouth when handled, and was refused when offered 

 to my baboons and Cercopithecus monkey." 



" On Jan. 1th 1 got a very fine large black Carabid [Anthia 

 fornasinii, Bert.] with dull white margin to elytra, running 

 over bare ground in moonlight. As it is a common type of 

 colouring 1 picked it up to see if it was the most common 

 species, and saw it was one I had not yet seen : I send it 

 to you. 1 was looking at it by full moonlight, holding it 

 about L8 inches away from my lace. The fluid which it
