Ornithomyia batchianica, Walk. (Journ. Proc. Linn. Soe. 
v. p. 300), from Batchian,=O. (Ornithoctona) nigricans, 
Leach (op. cit. p. 558, tab. xxvii. figs. 7-10). 
Ornithomyta (Ornithoctona) erythrocephala, Leach: op. cit. 
p. 559, tab. xxvii. figs. 4-6.—The type of this species, bearing 
a label in Leach’s handwriting, is in the Museum collection.

Ornithomyta vicina, Walk. (List Dipt. iv. p. 1144), from 
Jamaica, on Ephialtes grammicus and Psittacus leucocephalus, 
belongs to this genus, and may be identical with O. ({Orni- 
thomyta) confluenta, Say. 
Ornithoica beccartina, Rond. (Ann. Mus. Civ. Genov. xii. 
(1878), p. 160), the type of the genus Ornithoica, from 
Amboyna, on Ardea alba, is identical with O. (Ornithomyia) 
exilis, Walk. (Journ. Proc. Linn. Soc. v. (1861), p. 254), from 
Dorey, New Guinea. In spite of the great difference in 
locality, O. eatlis is possibly identical with O. vicina, Walk. ; 
if so, the latter name has priority. It has just been pointed 
- out, however, that O. weina, Walk., perhaps= O. confluenta, 
Say, in which case O. beccartina, Rond., and O. exilis, Walk., 
are also synonyms of O. confluenta, Say. My knowledge 
of this group is unfortunately insufficient to enable me to 
decide this question, and all I can say is that after carefully 
comparing our specimens of O. confluenta, vicina, and exilis, 
I have been unable to discover any characters which would 
warrant a positive assertion of their distinctness. 
ORNITHOPHILA, Rond. 
Ornithomyia simplex, Walk. (Journ. Proc. Linn. Soc. v. 
p. 263), from Menado, Celebes (A. &. Wallace), belongs to 
this genus; as also does an undetermined specimen from 
Natal (Guecnzius), and another, with unusually long palpi, 
from Port Molle, Queensland (H1.M.S. ‘ Rattlesnake’; collected 
by Macgillivray), trom Tallegalla Latham, 
STILBOMETOPA, Coquillett.: 
This genus was founded (Canad. Ent. xxxi. (1899), p. 336) 
for Ornithomyia fulvifrons, Walk. (List Dipt. iv. p. 1145), 
from Jamaica, of which, including the type, we have five
