XXXIV. Description of the male of Gastroxides ater, a 
Dipterous Insect belonging to the Family Tabanide. By 
W. W. Saunpers, Esq. F.L.S. 
[Read 7th July, 1845.] 
In the first part of the third volume of the Entomological Society’s 
Transactions I described a dipterous insect from the north of India, 
belonging to the family Tabanide, under the name of Gastroxides 
ater, At that time I was only acquainted with the female, but 
since then, through the kindness of Mr. Westwood, I have been 
allowed to examine and figure the male, which is in Col. Hearsey’s 
Collection, and differs from the female in having the second joint 
of the abdomen rufous, and the eyes large, and contiguous verti- 
cally. This figure and description I now beg leave to lay before 
the Society.
