inside my ' rakuba,' a temporary grass-built shelter which 

 was erected in tlie shade of some large trees locally called 

 Tameiza, of the Ficvs sycomorus, L., type. Since then I have 

 seen both these species resting inside hollow trees such as 

 Adausonia digilata (locally called Tebeldi) which grow to a 

 vast size and are nearly always hollow." 



Emission op fluid from the antennae of Acraea 

 QUIRINA, F. — Prof. Poui.TON exhibited a male example of 

 A. quirina, captured in Sierra Leone probably in the neigh- 

 bourhood of Freetown, June 18, 1917, by Lieut. P. A. Buxton, 

 E.A.M.C., who had made the observations recorded in the 

 following letter, written on June 20. 



" I am circunmavigating most of the known world on my 

 way to the Euphrates. I shall post to you a small Acraea 

 which I took recently. When I pinched it in the net I dis- 

 tinctly saw drops of yellowish fluid appear, one on the club 

 of each antenna — drops about the size of the head of a 

 domestic pin. This seemed interesting, so I took the thing 

 out of the net, pinched it again, and got the drops again, 

 but much smaller. Third attempt, no drops. This is the 

 only time I observed it, though I -got lots of small Acraeas 

 that day and subsequently, and kept my eyes open, of course. 

 Is it an old observation ? " 



Prof. Poulton said that the fact had been observed by 

 Dr. G. A. K. Marshall in Planema aganice, Hew., and Acraea 

 terpsicJiore, L., f. rougeti, Guer. {serena, F., htixtoni, Hew.). 

 See Trans. Ent. Soc, 1902, pp. 413 and 323 respectively. 



Larva of Saw-fly with " Palisade." — The Eev. F. D. 

 MoRiC'E exhibited a photograph of a saw-fly larva with the 

 epidiascope and described it as follows : — 



" I show a print from a negative already exhibited at a 

 previous meeting (Oct. 3). It represents a young (living) 

 larva of the sawfly Lygaeonematus compressicornis, F., feeding 

 in the middle of a poplar-leaf, and surrounded with a sort of 

 ' stockade,' or rather circle of little glassy nearly equidistant 

 ' pillars,' which are believed in some way to protect it, but 

 against what sort of attacks has never been clearly made 

 out (Plate C, fig. 2). In another photograph I show one 

 of the pillars separately, at a magnification of 20 diameters
