(H. H. Smith). 
Length no more than 4'5 millim. Metallic-violet, the last two abdominal segments 
bluish-green ; head ochraceous; eyes coalescent, the facets on the disc not enlarged ; 
antenne brown, their basal joints rufous; subhumeral cicatrix yellowish. Wings with 
~ an interrupted brownish costal patch, which at the end of the second vein is somewhat 
extended over the tip of the wing. 
Lucilia, sp.—A single male specimen from Costa Rica, Caché (Rogers). 
It agrees with the preceding in the coloration of the wings, the ochraceous head, 
the coalescent eyes, and the yellow subhumeral cicatrix; but it is of much larger 
size (7-5 millim.) and of a bright metallic-green colour, with obscure violet hind- 
borders to the abdominal segments. The front legs are rufous. Dorso-central bristles 
are absent. 
Lucilia, sp.—A single male specimen from Mexico, Northern Yucatan (Gaumer).

coalescent on the vertex; subhumeral cicatrix blackish ; dorso-central bristles distinct ;

1. Pyrellia suspicax. 
Pyrellia suspicaz, Walk. Trans. Ent. Lond. new ser. v. p. 312 ( g) (1861) *. 
Pyreilia iris, Bigot, Ann. Soc. Ent. Fr. 1878, p. 36 (¢? )*. 
Hab. Mexico 12, Sierra de las Aguas Escondidas 7000 feet and Omilteme 8000 feet, 
both in Guerrero (H. H. Smith), Orizaba (H. H. Smith and FP. D. Godman). 
Four male and two female specimens. Walker’s description of the male agrees 
with the specimens before me. Of the two black marks on the costa, one is imme- 
diately beyond the humeral cross-vein, the other at the end of the auxiliary vein; they 
are present in both sexes, but not very conspicuous. Bigot, in his description of 
P. iris (@), makes no mention of these markings, but for the rest his description 
applies, as, for instance, the dark tegule. 
The thoracic dorsum has distinct dorso-central bristles; in the male the eyes are 
nearly coalescent and their central facets are larger than the others.
