276 . THE ZOOLOGIST. 
“The Mantis was sitting on a grass-stem, holding the Cicada on its back, 
and biting it on the hind wing, which you will see is damaged in con- 
sequence. My attention was attracted to it by the unusually loud noise 
the Cicada was making.” ‘This narrative is also interesting as showing 
that the stridulation of the Cicada is also used as a sign of alarm or pain, 
and is not of a purely sexual or esthetic character.— Ep. 
Southerly Extension of the East African Butterfly Fauna.—Durban, 
the well-known port of Natal, is the home of several good lepidopterists, 
the name of Col. Bowker being a host in itself; consequently the butter- 
flies of that neighbourhood have been well and persistently collected, and 
there is little chance of prominent species being overlooked. Of late years 
several species hitherto considered as part of the Mozambique fauna have 
appeared at Durban, such as Godartia wakefieldii, which I took myself when 
at that spot in 1896. Last year Dr. Dimock Brown, who was in England, 
called and showed me a specimen of Crenis rosa, originally described from 
Delagoa Bay, which he had captured in the Durban Botanical Gardens ; 
and now Mr. A. T. Millar informs me that this year at least a dozen 
specimens of that species have been captured about Durban, and in such 
splendid condition as to prove they had but recently emerged in the imago 
condition ; so that C. rosa may now definitely be included in the Natal 
lists. The route followed is evidently the coast forest belt, which extends 
from Delagoa Bay to and beyond Natal, and further visitors may be 
expected.— Eb.
