EUXESTA. 397 
1. Euxesta laticeps, sp.n., ¢. (Tab. XI. figg. 7, wing; 7 @, head seen from 
in front; 7 6, head in profile.) 
Greenish metallic; head very broad; front and legs rufous; wings hyaline, with two costal spots. 
Length 4°5 millim. 
- - Head, seen from in front, much broader than high; front yellowish-rufous, in the middle with a transverse 
groove, the orbits of the eyes narrowly white ; ocellar spot greenish-black ; face short and broad, nearly 
white ; clypeus rufous; upper part of the occiput, behind the eyes, metallic green. Antenne dark 
rufous; third joint rounded. Proboscis black. Thorax, scutellum, and abdomen metallic blackish- 
green, somewhat coppery ; the flattened first joint of the ovipositor metallic black, the aculeate second 
and third joints rufous. Fore legs rufous, with the base of the coxe, femora, and tibie, the apical third 
of the tibie, and the whole tarsi, blackish; middle and hind legs rufous, with the coxe metallic black 
and the tip of the tibie and the tarsi, save the basal joint, infuscate. Wings hyaline, with yellowish 
veins and two blackish costal spots—one at the end of the mediastinal cell, the other subapical at the 
end of the second vein and extended to the third vein; last section of the fourth vein converging with 
the third vein. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
A single female specimen. This insect must be closely allied to L. spoliata, Low ; 
but as it differs in the coloration of the legs, and the peculiar shape of the head is not 
mentioned in the description (Low merely states that the face is unusually short), it 
cannot be referred to that species. 
Ortalis platystoma, Thoms. (Dipt. Eugenie’s Resa, p. 572), from Panama, certainly 
belongs to the genus Euvesta, and agrees with it in the enlarged head, the general 
coloration, and the pattern of the wings. It appears to differ from &. lateceps in 
having two green points on the sides of the front, and the hind femora blackish at 
the tip. 
2. Huxesta nigricans, sp.n.,g. (Tab. XI. fig. 8, wing.) 
Blackish; pleure with metallic reflections; antenne dark rufous; legs black, the hind tarsi rufous; wings 
hyaline, with four blackish cross-bands, the first, second, and fourth abbreviated. 
Length 3°5 millim. 
Head, seen from in front, rounded, not broader than high; front dark rufous, short-haired ; the vertex with 
several bristles; the orbits narrowly white; face and occiput cinereous. Antenne dark rufous; third 
joint rounded. Proboscis thick, brown. Thorax, scutellum, and abdomen black; the pleure greenish- 
metallic. Legs black, the knees and the first joint of the hind tarsi rufous, Halteres whitish. Wings 
hyaline, with four blackish cross-bands: the first near the base, reaching the first basal cell ; the second 
covering the end of the mediastinal cell and also terminating in the first basal cell, a little before 
the small cross-vein ; the third narrower and much longer than the second, extending as a border of the 
posterior cross-vein to near the hind margin ; the fourth reduced to a subapical spot, at the end of the 
second vein, and not extending beyond the third vein; third and fourth veins convergent towards the tip 
of the wing. 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 
A single male specimen. 
3. Euxesta latifasciata, sp. n., ¢(91). (Tab. XI. fig. 9, wing.) 
Metallic bluish-black ; head, antennew, and legs rufous; wings with four blackish cross-bands, the second and
