620 Prof. Mario Bezzi’s Report on a Collection of 
TYPE ¢ from North Nyasa, Deep Bay to Vua, May 14, 
1909 (Dr. J. B. Davey); additional specimens, all males, 
from Deep Bay, November 3, 1909; near Virauli Mt., 
July 23, 1909; from Karonga to Fort Hill, near Lufira 
River, May 30, 1909; from Akamanga, South Rukuru 
River, October 10, 1909 (all by Dr. J. B. Davey). 
Type § and a male from Nyasaland, Fort Johnston, 
2000 ft., June 1910 (Dr. A. H. Barclay). 
10. Anthrax, Scopoli (1763). 
This is not the Anthrax of authors, but as I showed in 
my paper of 1908 (Zeitschr. 7. Hymenopterol. u. Dipteralog., 
p. 34) is the same as Avgyramoeba, Schiner, as restricted 
by Dr. Sack in his monograph of 1909. 
The genus seems to be very well represented in the 
Ethiopian fauna, as the collection contains many species ; 
those before me can be distinguished as follows :— 
1 (8). Upper branch of the fork of the third vein bent at a right 
angle in the middle, and with an appendix at the angle. 
2 (3). Apical half of the wings with many confluent black spots ; 
basal appendix very long; discal cell darkened in the 
greater part ; squamulae dark. . . pithecius, Fabr. 
3 (2). Apical portion of the wings wholly hyaline, or with 2-3 
separated black spots only ; discal cell in the greater 
part clear ; basal appendix short; squamulae white. 
4 (5). The basal dark marking of the wings extends broadly beyond 
the small cross-vein, and is in contact with the spots at 
the base of the cubital fork and at the end of the discal 
cell; no hyaline spot before the small cross-vein ; 
plumula with a black fringe ; . diffusus, Wied. 
5 (4). Dark marking ending a little beyond the small cross-vein, 
and not coalescing with the cubital spot; end of the 
discal cell not spotted ; hyaline spot at the end of the 
first basal cell just before the small cross-vein ; plumula 
with a white fringe. 
6 (7). Species of greater size, with larger rounded brown spots 
at the bases of cubital fork and third posterior cell ; 
anal cell closed at the wing margin . aygulus, Fabr. 
7 (6). Species of smaller size ; a small cloud only at the base of 
cubital fork, that at the base of third cell not separated ; 
anal cell open : : : homogeneus, sp. N. 
8 (1). Upper branch of the catital fork gently curved or bent at 
an obtuse angle, without appendix.
