FOSSORIAL HYMENOPTERA

I hope these notes will lead others to watch them. They 
are the most easily studied of any Hymenoptera. So long as one

the prey alone. 
The observations herein upon Bernbex were published

appeared in sundry publications of the Entomological Society

I have bracketed both these diseases together, as, until a few 
days ago, I have been unable to discover that the Lumbwa 
differentiate in any way between the two. The disease is 
endemic in this district, carrying off both adult and young 
stock — mostly the latter. It appears to break out with 
particular violence towards the close of the dry weather, and 
disappears again in the epidemic form with the advent of 
the rains. The two names used — as far as I can discover, 
interchangeably — refer to different symptoms. Kakatanet is 
the Lumbwa for the gall-bladder, and this appears to swell 
up and become full of a blackish-coloured liquid. Kipkaita 
refers to the diarrhoea or dysentery from which the animal 
suffers. In the case of adult stock, death takes place on the 
fifth day from the time the animal gets sick. Dysentery 
appears on the third day. If the animal survives past the
