180 CURRENT NOTES. 
information regarding the distribution of this bed-bug both in the Lado and in 
the Bahr-El-Ghazal. It is worthy of note that the first case of kala-azar found 
in the Sudan by Neave was a boy who had recently come from Meshr-El-Rek, 
in the Bahr-E1-Ghazal Province.” 
Although it is quite probable that C. rotundatus may have been introduced 
into the Red Sea Province of the Sudan, from Arabia, yet there seems reason to 
believe that this species is the common bed-bug of Tropical Africa, Examples 
of it have recently been received by the Entomological Research Committee from 
the following localities: —NyasaLanp: North Rukuru River (Dr. J. B. Davey), 
Zomba (Dr, H. Hearsey and A. M. D. Turnbull), Blantyre (Dr. J. E. S. Old) ; 
N. I. Reopesta: various localities (S. A. Neave); NortHEern NIGERIA: 
Zungeru (J. J. Simpson) ; SOUTHERN Nigeria: Benin City (Dr. R. W. Gray); 
whereas no C, lectularius have been sent from these localities. 
A Locustid injurious to Man. 
With reference to this subject, Dr. Hugh S. Stannus writes from Zomba, 
Nyasaland, as follows :—‘* In a recent number of the Bulletin Dr. C. A. Wiggins, 
of Entebbe, Uganda, gives notes upon a Locustid, Knyaliopsis durandi, whose 
bite, he says, ‘ gives rise to a very nasty eruption . . . the skin at the site 
of the bite sloughs away,’ &c. An editorial note states that immature specimens 
of the allied /. peters? emits a clear yellow fluid from the sides of the body when 
handled, and mentions that these insects have no poison glands. For some 
years I have been cognisant of the fact that among the natives of Nyasaland an 
allied if not the same species is held to cause skin lesions by the emission of a 
fluid on the bare skin surface of the body. The Yao name for the insect 
is ‘ Nantundira’ (from ‘kutunda,’ to make water); the Anyanja call it 
‘Nalibvibvi.’ I have seen cases of ulcers on various parts of the body for which 
the ‘ Nantundira’ was assigned as the cause. 
“Curiosity prompted me to seek further, and haying asked for a volunteer, I 
procured a specimen of the Locustid in question, and tested the truth of the 
native statement. The insect was put on to the arm of the native, and then 
worried with a penholder. It promptly emitted a slightly yellowish clear fluid 
from pores at the side of the body near the junction of the thorax and abdomen. 
This secretion was allowed to remain on the arm. In a few hours a sensation of 
burning was produced, the skin showed signs of reaction, swelling and redness, 
and twelve hours later the superficial layers appeared to be dissolved, so that the 
pink skin beneath was visible, covered by a serous exudation. This superficial 
destruction of tissue healed in a few days without trouble. The secretion was 
acid to litmus. 
“ T have little doubt that such a breach of surface may in many cases be the 
starting point for extensive ulceration, if it becomes infected, as in a similar way 
small abrasions in the native are often followed by ulceration, owing to lack of 
proper treatment. I am inclined to think that Dr. Wiggins, in using the term 
‘bite,’ is repeating native evidence, and that the explanation of the production 
of ulceration and sloughing is the same as I have mentioned as occurring in this 
country.”
