300 ERNEIST WARREN. 



Durban. These specimens have been kindly submitted to me 

 by Mr. E. C. Chubb, Curator of the Museum, and they certainly 

 belong to the species P. akermani. 



Subsequently I was informed (in litt, 27/3/15) by Dr. F. 

 Silvestri that he had found a similar terniitophile in the nest 

 of Enter 111 es trinervius in West Africa; quite possibly 

 this also is akermani. 



The specimens found in Natal are the following : 



Environs of Pietermaritzburg : Durban Road (Akerman), 

 one specimen, March, 1913 ; Botanical Gardens (Cullingworth), 

 one, July, 1913; Zwart Kop Road ("Warren), one, July, 1913 ; 

 Bisley Road (Warren), one, December, 1913 ; Town Hill 

 (Akerman), five in one nest, September, 1917. 



Natal Coast: Durban (Boyce), three in one nest, March, 

 1915; Winkle Spruit (Akerman), two in one nest, May, 1917. 



Of these 14 I have examined all but one. There were three 

 undoubted males, 6 undoubted females, and the sex of the 

 remaining 4 could not be determined without mutilation. 



It was in June, 1905, that Dr. Tragardh found numerous 

 specimens of his Termitomimus entendveniensis in 

 Eutermes nests in Zululand, and from his published account 

 of the anatomy it will be seen that this beetle bears some 

 striking similarities to Paracorotoca akermani. 



In June, 1916, I found many specimens of Termito- 

 mimus, belonging undoubtedly to Tragardh's species, in the 

 nests of Evitermes trinervif ormis Holm, in a restricted 

 area in the environs of Pietermaritzburg, and subsequently 

 Dr. Akerman found the same species in a neighbouring 

 locality. 



The pupae of Paracorotoca and Termitomimus are 

 unknown, but certain Staphylinid larvae modified in a termi- 

 tophilous manner have sometimes been found fairly abundantly 

 in the nests in which adult Paracorotoca occurred; also, 

 one specimen of a somewhat differently shaped Staphylinid 

 larva was discovered in a nest containing numerous adult 

 T e r m i t o m i m u s . There would seem to be little doubt that 

 these larvcG may be referred to the two physogastric beetles,
