Dr. Perkins, referring to these fine observations, had written 

 with natural gratification : — 



"It is remarkable that the biology of Bethylidae should 

 have been so much elucidated in little Hawaii, with its meagre 

 fauna ! The biological work on the allied Dryinidae was also 

 published there, being the result of observations of Hawaiian 

 entomologists. So also that on the Pipunculus flies and on the 

 Stylopidae. There is no doubt that Hawaii can congratulate 

 itself on the work of its band of entomologists ! " 



Fellows of the Entomological Society would also wish to add 

 their congratulations. 



Mr. a. Loveridge's notes on the Driver- Ant Dorylus 



NIGRICANS IlLIG., AT KiLOSA, TANGANYIKA TERRITORY. — 



Prof. PouLTON gave an account of the following notes and 

 exhibited the specimens referred to by the author. In the 

 determination of the species he had received the kind help 

 of Dr. a. A. K. Marshall and Mr. W. C. Crawley. A few 

 additional facts recorded below were quoted from letters 

 written between July 11, 1921, and March 1, 1922. 



" Kilosa is now spelt with one ' s ' — Roy. Geogr. Soc. ruling." 

 It was spelt " Kilossa " in Proc. Ent. Soc, 1921, pp. Ixii, xci. 



The " Marmalade Ant " {Camponotus maculatus F.) was 

 described as " harassed by Driver- Ants," the " Cocktail Ant " 

 {Cremastogaster castanea Sm., r. tricolor Gerst.) and the " Small 

 Ant " [Pheidole sp.) as " left in peace." The " Lesser Stink- 

 Ant " — " a match for the Driver- Ants," — was so called " as 

 we have an outsize in these creatures here." 



The " Green Bug," Platacantha lutea Westv/., " which came 

 to light in great numbers during the rains, was comparatively 

 scarce at the time of the invasion, but was eaten by the 

 Drivers." The " Brown Bug," Nezara chloris Westw., also eaten, 

 " began coming to light in great numbers during the rains." 



From a later letter — " I have only recently read Carpenter's 

 notes on the Uganda Driver-Ants [Proc. Ent. Soc, 1914, 

 p. cix] in which he says that they approached but retreated 

 from a bug, and he suggests that the peculiar odour of the bug 

 may have protected it. The reverse happened here. Drivers 

 swarming to the spot where a bug was and the whole house 

 reeking of the smell."
