PYRALID:. 
Margaronia sericea, Dru. (1).—A West African species. 
ZY GARNID Ab. 
Euchromia fulvida, Butl. (2.)—A West African species. 
Of the eighty forms comprised in the above list, sixty-nine are, 
so far as is known, peculiar to the Ethiopian region, and thirty- 
nine of these have hitherto been found only in West Africa. 
Five of the remaining eleven are common to the Ethiopian and 
Oriental regions, one to those two regions and also to the Pale- 
arctic, four to the Ethiopian, Oriental, and Australian regions, 
and one to all the regions of the Old World. It will be noticed, 
therefore, that about fifteen per cent. of the species are not peculiar 
to the region in which they were found. This is an indication 
of the fact that there is less speciality in the lepidopterous than 
in the vertebrate fauna of each great zoological division of the 
earth’s surface. The relationship between the Ethiopian and 
Oriental faunas, shown in this small collection by the specific 
identity of such a fair number of insects with Indian forms, 
would, in a collection of vertebrates, be indicated hardly at all 
by identical species, but only by common genera or families.
