130 HTMENOPTEEA. 



2. Epistenia maculipes. (Tab. VI. fig. 4, ? ; 4 a, antenna; 4*, fore leg; 4c, 

 maxilla and maxillary palpus.) 



Mgro-viridis ; antennis nigris ; pedibus rufis, coxis nigris, tibiis tarsisque posterioribus fuscis ; alis hyalinis, 



fusco maculatis. 

 Long. 9 millim. 



Hab. Panama, Bugaba (Champion). 



Head finely, thorax coarsely, punctured; pleurae finely punctured, smooth and 

 shining at the top. Antennal grooves less strongly punctured and less metallic than 

 the vertex. Head and thorax closely covered with a pale down. Abdomen alutaceous, 

 covered with a pale pubescence at the sides and apex. The apex of the pronotum, a 

 stripe across the mesonotum at the tegulae, the upperside of the pleurae, and the sides 

 of the metanotum are green. The legs are covered with a pale, longish pubescence. 

 The coxae are punctured. The apices of the posterior tibiae are not fuscous, the 

 same parts of middle tibiae paler ; the hind femora are black at their apices laterally. 

 All the parts of the legs tend to become more or less fuscous; the apices of the 

 coxae, and the trochanters, are usually white. At the base and apex the abdomen is 

 smooth and shining, the rest finely and closely punctured; the segmental divisions, 

 however, being smooth and shining; the base and middle are dark blackish purple, 

 the apex golden. The male does not differ in coloration. 



Differs from E. balteata in the thorax being much more closely and finely punctured, 

 in the longer prothorax and metathorax, and much shorter ovipositor, the latter 

 scarcely longer than the second segment, while in E. balteata it is nearly as long as the 

 abdomen itself. The size of the fuscous fasciae on the wings varies. 



3. Epistenia rufipes. 



Viridis; terebra flagelloque antennarum nigris, pedibus tegulisque rufis j alis subfumatis, nervis sordide 



testaeeis. 

 Long. 8 millim. 



Hob. Panama, Bugaba (Champion). 



Head and thorax coarsely punctured all over, the punctuation on face finer, the latter 

 sparsely covered with longish white hairs. Prothorax short, subtransverse. Scutellum 

 with a distinct border behind its apex; the border forming a tooth, which projects over 

 the metanotum. Abdomen not much longer than head and thorax together ; the base, 

 a narrow band in the middle, and the apical half blackish purple ; the middle punc- 

 tured, base and apex smooth, shining. Ovipositor but shortly projecting. 



AMOTURA. 



Antennae 10-jointed, situated not far from the mouth. Scape three fourths of the 

 length of the flagellum, compressed and dilated at the apex, the dilated portion forming 

 a broad knife-like keel. First joint of flagellum cylindrical, longer than any of the
