Described from 2 female specimens collected by Charles Robertson 

 and bearing his numbers 12716 and 12754, respectively. The speci- 

 men bearing No. 12716 is the holotype. 



ORASEMA BAKERI, new species 



This species is not easily distinguished from viridis and cocherelli^ 

 but it differs from both by having the supraclypeal area as broad as 

 long and the clypeal foveae unusually large and deep. The abdomi- 

 nal petiole is distinctly shorter than in viridis and the color is much 

 less distinctly aeneous than in cockerelU. The shorter and more 

 evenly sculptured petiole, the larger and deeper clypeal foveae, and 

 slight differences in color and sculpture are all that distinguish it 

 from loheeleri. 



Female. — Length 3.25 mm. Head and thorax dark green in color 

 with a slight brassy tinge, stronger on the face ; scape reddish testa- 

 ceous, pedicel fuscotestaceous, flagellum brownish black; coxae 

 concolorous with thorax; femora all dark f uscometallic ; trochanters, 

 apices of femora more or less, all tibiae, and all tarsi reddish tes- 

 taceous; tegulae brownish: propodeum and abdominal petiole dark 

 bluish green, sometimes with a purplish tinge; gaster shining dark 

 green ; wings hyaline, venation yellowish. 



Head with alveolate sculpture, the alveolae on face, frons, and 

 temples irregular in shape and somewhat coarser than on vertex; 

 dorsum of thorax sculptured like the head, the posterior portion of 

 prescutum, the axillae dorsally, and the scutellum dorsally with very 

 fine, nearly round, alveolae; the anterior portion of prescutum and 

 the scapulae with the alveolae more irregular in shape and those on 

 scapulae distinctly shallower than on prescutum; transverse fold on 

 scutellum present but not distinctly foveated, the lateral grooves 

 distinct and weakly foveated; propodeum very finely alveolately 

 punctate, with some foveae along the anterior margin, but without 

 carinae, the spiracular grooves deep and complete and weakly 

 foveated; pleura nearly uniformly finely alveolate, with the prepec- 

 toral triangle not sharply margined anteriorly ; coxae distinctly sculp- 

 tured ; abdominal petiole about as long as broad and evenly alveolate 

 like propodeum ; second sternite as well as rest of gaster smooth. 



Head viewed from in front broader than long, about in the propor- 

 tion of 50 to 40; clypeus distinctly broader than long, its anterior 

 margin very nearly straight; clypeal foveae very broad and deep; 

 supraclypeal area well defined, separated from clypeus by a deep 

 depression connecting the clypeal foveae, at least as broad as long 

 and usually a little broader than long; malar space very nearly as 

 long as eye, flattened but without a distinct longitudinal depression ; 

 ocellocular line nearly equal to the distance between posterior ocelli 

 and a little more than twice as long as the long diameter of a lateral
