ENTOMOLOGY 847 
Edwards the midge is an undescribed species, probably of a new genus. It is 
remarkable in having no claws, while the empodium has a most peculiar struc- 
ture. There seems to be only one previous record of midges attacking dragon- 
flies. KE. Jacobson, in Sumatra, observed on two occasions midges fixed to the 
wings of these insects, in one case of the species Anax magnus Rambur. ‘The 
midge has been described by de Meijere as Ceratopogon aeschnosuga (1923, 
Tijdschr. v. Entom., LXVI, p. 187, fig. 1; ¢).1 This species likewise lacks 
claws, and probably belongs in the same genus as the Liberian one.

Liperia. — Lenga Town, August 17, 1926, biting man in the village at 
6 A.M. 
BELGIAN Congo. — Kisenyi, on the northern shore of Lake Kivu, 1,460 m., 
February 13, 1927, biting man at 7 a.m. Burunga, 1,800 m., February 17, 1927, 
biting man about 9 a.m. In the Semliki Valley, May 17, 1927, biting man. 
Slopes of Mt. Ninagongo at 2,300 m., February 15, 1927, biting man at 9 a.m. 
A most vicious and troublesome insect, which bites in broad daylight, though 
preferably in the evening about dusk and in the early morning. It is extremely 
abundant in the forested part of the Semliki Valley (Bwambwa Country). 
Carter, Ingram, and Macfie, in Sierra Leone, found the larvae in decaying vege- 
table matter at the base of banana stumps. 
C. grahamii is the commonest and most widely distributed of the African 
punkies, being known from Sierra Leone to Uganda and Angola. 
In British Cameroon, N. A. D. Sharp (1928, Trans. Roy. Soc. Trop. Med. 
Hyg., X XI, 5, pp. 371-396) found that the embryos of the worm, Acanthocheilo- 
nema perstans (Manson), develop in C. grahami during at least three days. 
Probably this midge also may act as an intermediary host of the parasite.
