This last species is placed under Silvius by Karsch as 
probably belonging to that genus, but the antenne were 
broken off and the eyes are not mentioned, so that it cannot 
be included in the above table, but is placed last with a 
short description to aid its identification. 
In No. 6 the eyes are not mentioned; it is presumed they 
are bare. 
Silvius decorus, Macq., is imserted in the table after 
Macquart’s description and figure, which do not bring it 
into line with S. decipiens, Loew, with which Loew supposes 
it may be identical. 
Silvius glandicolor, 3 , Loew. 
One male and one female specimen in poor preservation 
from Port Natal, 58. 13. 
The female has the forehead shining, similar to the species 
described by Macquart, in Dipt. Exot. 1. p. 32, as Zabanus 
fallax, which Loew suggests may be the same as the species 
he described as S. glandicolor, but the colouring of the legs 
differs in the two species.
