I have been able to study a very interesting collection 
of Asilidae made by this excellent Dipterist mostly in 
the northern part of Egypt. The smaller species of 
this great dipterous family, so often neglected by col¬ 
lectors, were here represented by great numbers of 
specimens, so that the variation could easily he stu¬ 
died. Also the geographical distribution of many a 
species proved to be very interesting both in the pre¬ 
sence of some species known from the Ethiopian Re¬ 
gion, and in the confluence of those from the Western 
Mediterranean Regions with such from Arabia and 
Southern Asia. I found in the collection n species 
recorded by Prof. Bezzi (Bull. Soc. Hist. Nat. de l’A- 
frique du Nord, 1912, No. 4 ) from Tunis; 4 species 
from Algeria and i 4 species were previously described 
from Arabia and Southern Asia. Two species belong 
to the purely African fauna. 
In the arrangement of the sub-families I follow 
the new grouping proposed by Back, Hermann and 
Williston, beginning with I Leptogastrinae (no spe¬ 
cies in the collection), II Asilincie, III Dasypogonmae 
and their subdivisions after Hermann (Zool. Jahrh. 
1920, Bui. 43 ), IV Laphriinae.
