ORASEMA STRAMINEIPES Cameron 



Orasema stramineipes Cameeon, Biologia Centrali-Americana, vol. 1, p. 105, 



pi. 6, figs. 18, a, b, c, d, e, 1884. 

 Orasema flavipes Cameron, Biologia Centrali-Amercaiia, vol. 1, pi. 5, figs. 

 20, a, b, c, 1884. 



In the description of stramineipes Cameron refers to figures on 

 plates 5 and 6. On plate 5 the figures cited are referred to the name 

 ■flavipes, while those on plate 6 are referred to stramineipes. The 

 name favipes is evidently a lapsus calami and should be considered 

 a synonym of stramineipes. 



This species, which is the genotype, was originally described from 

 Panama. It is not represented in the National Museum collection 

 and is placed in the key solely on the basis of the original description. 



ORASEMA MINUTISSIMA Howard 



Orasema minutissima Howard, Journ. Linn. Soc. London, Zool., vol. 25, p. 84, 

 1894. 



This unusually small species has the head and thorax bluish green, 

 this color on face and underside of thorax more or less diluted 

 with testaceous. The abdomen is blackish, also diluted with testa- 

 ceous and with a slight metallic tinge in some lights. The antennae, 

 tegulae, and all the legs, including their coxae, are testaceous, the 

 flagellum of antennae and the coxae sometimes more or less fuscous. 

 The wings are hyaline. 



The sculpture of head and thorax is comparatively weak, consisting 

 of shallow more or less irregularly shaped areas, which are not quite 

 uniform in size and shape and hence not so distinctly alveolate as in 

 most of the following species. The scutellum has the transverse 

 fold very weak or subobsolete, and the usual lateral grooves are ab- 

 sent. The propodeum is weakly sculptured and has a very delicate 

 median longitudinal carina. The coxae are practically sculptureless. 

 The abdominal petiole is about as long as the hind coxae and weakly 

 sculptured. The stigmal vein is barely longer than broad and the 

 postmarginal fully half as long as marginal. 



Four female paratypes of this species from the island of St. Vin- 

 cent are in the collection of the U. S. National Museum. There are 

 also two females taken at Mina Carlota, in the Trinidad Mountains
