The genus Margarodes, originally erected to contain the 
single species formicarum and, for a long time, restricted to that 
species, is now justly considered to include Porphyrophora of 
Brandt. Sphaeraspis was suggested, by Giard, as a subgeneric 
name to contain the species vitcwm and capensis, but there seems 
no good reason to separate these from the other typical species. 
At the present date eleven reputed species are recognized, of 
which the recorded distribution is as follows :— 
Europe :—gallica, polonicus, perrisit and medtterraneus. 
Turkey in Asia (Armenia) :—hamelit. 
Africa :—capensts, triment. 
United States and West Indian Islands:—formicarum, rileyt, 
hiemalis. 
Chili :—vittum. 
Dr. Giard, in a manuscript note to a paper on the geographi- 
cal distribution of Margarodes, mentions the receipt of a species 
(allied to formicarum, triment, etc.) from Madagascar. In the 
same paper he states, on the authority of Trimen, that there are 
certain indications of the existence of the genus Margarodes in 
Australia. 
In addition to the above localities, Mrs. Fernald—in her 
Catalogue—attributes capensis, vileyt and hamelit to Europe, 
polonicus to Central America, and formicarum to the East Indies; 
but I can find no authority for these records, and am inclined 
to believe that they have been inserted in error, or owing to 
faulty identification. ‘The species capensis is certainly confined 
to South Africa: vileyi is similarly peculiar to Central America, 
unless—as suggested by Giard—it is identical with hzemalis of 
Cockerell. I am uncertain about polontcus, but it seems extremely 
doubtful that it should occur in such widely separated countries 
as Europe and Mexico. It is equally doubtful if formicarum (or 
any other species of Margarodes) has ever been found in the East 
Indies.
