Guerin and Percheron, Genera des Inseetes, 6 e Livr., No. 9, 
Dipteres, PL VI (no sex; with description, without local- 
ity), has evidently nothing in common with Olfersia fusca 
Macquart. The very large size (length 5 lines = 11 mm.), 
and the statement that ocelli were present, would seem to 
point to a species of Ornithoctona. The figures, it is true, 
do not show the closed anal cell, but this may be due to an 
oversight. It should, moreover, be noted that some at least 
of the detail drawings were made from Ornithomyia avicu- 
laria.
