blackish cross-bands: the first very small, at the humeral cross-vein ; the second much broader, at the 
end of the mediastinal cell, and reaching with its outer side to near the small cross-vein ; the third 
narrower, especially where it borders the posterior cross-vein ; the fourth in the form of a rather broad 
border at the tip of the wing ; the third and fourth cross-bands are connected with each other by a very 
narrow infuscation atthe costal vein; the hind margin of the wing is greyish; the third and fourth 
veins are distinctly convergent. 
Hab. Mexico, Orizaba (H. H. Smith & F. D. Godman). 
A single male specimen.

Five males and two females. They agree fully with Loéw’s description. The 
ovipositor of the female is similar to that of the allied species; it has the cylindrical 
terminal joint pale rufous. . alternans is nearly allied to EL. major, but it is of much 
smaller size (length 4 millim.); the front is more rufous; the abdomen is steel-blue ; 
the two median cross-bands fully reach the hind margin of the wing, and the third 
and fourth cross-bands are not connected at the costa. |

Four males and three females, agreeing exactly with Low’s description. This species 
is easily recognizable by the black spot between the antenne. ‘The second cross-band 
of the wings is less intense beyond the fourth vein; the third cross-band is much 
attenuated where it borders the posterior cross-vein, and on the costa it is fully 
connected with the fourth cross-band. 
8. Euxesta conserta, sp.n.,¢. (Tab. XI. fig. 14, wing.) 
Metallic greenish-black; head and legs rufous; wings with four blackish cross-bands, the third and fourth 
connected at the costa. 
Length 3°5 millim. 
Head rounded ; front rufous, as broad as the eyes, with parallel sides ; vertex metallic green ; frontal bristles 
very short, the ocellar and post-vertical bristles much longer; face pale rufous, with metallic-blue 
reflections. Antenns, proboscis, and palpi rufous; third antennal joint oval. Thorax, scutellum, and 
abdomen metallic greenish-black. Legs dark rufous, the femora and tibia more or less infuscate ; middle 
and hind coxe greenish-black. Halteres yellow. Wings hyaline, with four blackish cross-bands: the 
first is very small at the humeral cross-vein, and extending to the base of the second basal cell; the
