Phorocera melanoceps, Bigot, Ann. Soc. Ent. Fr. 1888, p. 260’. 
I have examined a typical specimen of Bigot’s species, and find that it does not differ 
from P. atriceps, both being from Mexico!, The French author's name has priority, 
but I do not propose to adopt it, the word melanoceps not being grammatically 
composed. 
Phorocera xanthura (p. 80). 
To the locality given, add :—Mexico, Amula in Guerrero (H. H. Smith). 
The male received from Amula agrees with the description, which was taken from a 
female, except in the following points:—The frontal band is blackish-brown and less 
sharply limited; the palpi have a rufous tip *. and the sides of the second and third 
abdominal segments are somewhat ochraceous.

The female specimen from Guerrero agrees very well with the description of 
Macquart 1, the insect being elongate in shape and having the first abdominal segment 
as long as the following. As in P. sobrina and P. setigera (antea, p. 84), the third 
vein has a row of short bristles extending from the base to the small cross-vein, a 
character not mentioned by Macquart. 
The analytical table (anted, p. 76) must be amended to include the present species :— 
16. First abdominal segment as long as the following . . - - - + + tenuiseta, Macq.
