Described from one specimen collected at Higuito, San Mateo, 

 Costa Eica. (Pablo Schild.) 



r?/^e.— Male, Cat. No. 40392, U.S.N.M. 



The species differs from Metti and scHhcce in having the tarsi 

 light yellow, but resembles them in the venation. 



LABIA ROSTKATA, new species 



Male. — Length, 8.5 mm. 



Color golden green, the humeri and scutellum more coppery. 

 Head convex in front, the vertical triangle coppery; without ocelli. 

 Antennae black, the third joint blunt, distinctly yellow at extreme 

 base ; eyes with long pale pile. Thorax densely covered throughout 

 with furry light yellow pile through which the ground color is visible 

 rather indistinctly. Abdomen golden green; first three segments 

 with pile similar to that on the thorax, but a little deeper yellow on 

 the sides of the segments tending to become brown. Last segment 

 with long, silky, pale yellow hairs, especially on the sides. Front 

 coxae green ; femora and tibiae dark brown ; knees and tarsi yellow. 

 The femora and tibiae are covered with almost white pile. Calypters 

 translucent light yellow with yellow rim and covered with dense 

 pale pile. 



Wings hyaline, first and second veins joining the costa separately; 

 the anterior branch of the third vein joins the costa distinctly be- 

 yond the second vein; so that the venation is like the figure given 

 by Wiedemann for splendens.^ 



The proboscis is remarkably long, so that it projects behind the 

 abdomen about two-fifths of its own length. 



Described from one male, collected at Higuito, San Mateo, Costa 

 Rica (Pablo Schild). 



T^/pe.— Male, Cat. No. 40393, U.S.N.M. 



This species agrees so well with Wiedemann's description and 

 figure of splendens that I would have identified it as that species if 

 I could have seen anything corresponding to the thoracic stripes 

 which Wiedemann mentions and figures. They are entirely absent 

 on this specimen. 



A female specimen from the same place and taken by the same col- 

 lector agrees in most characters, including head structure and vena- 

 tion. The proboscis, however, is much shorter, projecting only a 

 little beyond the tip of the abdomen; while the ground color of the 

 abdomen is blackish with very little metallic reflection; the pile of 

 the abdomen is largely dark brown. Although it is probable that 

 this belongs to the same species I did not venture to label it as the 

 allotype.
