ORASEMA TOLTECA Mann 



Orasema toUeca Mann, Psyche, vol. 21, p. 183, 1914. 



This unusually large species, the type of which measures over 4 mm. 

 in length, is metallic green in color with the head mostly metallic 

 green with a strong aeneous tinge on f rons and face, the thorax metallic 

 green but strongly aeneous dorsally as well as on the pleura, the coxae 

 green, the femora dark metallic except apically, and the abdomen pol- 

 ished bluish green. The antennal scape is metallic and the flagellum 

 black. The tegulae are metallic green. The legs except their femora 

 are reddish testaceous, and the wings hyaline. 



The sculpture of f rons and face is distinctly alveolate while that of 

 vertex, occiput, and temples is more irregular. The clypeus is prac- 

 tically smooth and polished, its anterior margin straight. The supra- 

 elypeal area is nearly twice as long as broad, indistinctly separated 

 from the clypeus by a depression but not a furrow, its surface dis- 

 tinctly sculptured but more weakly so than the frons. The malar space 

 is a little longer than the height of the eye, and there is a broad shallow 

 depression extending from the eye margin to the base of mandible. 

 The ocellocular line is distinctly a little longer than the distance be- 

 tween the posterior ocelli. The antennal flagellum is distinctly thicker 

 than the short pedicel, not thicker apically than basally, its first seg- 

 ment about twice as long as broad, the following segments successively 

 decreasing slightly in length, the last three subequal and each about as 

 long as broad. The mesoscutum is strongly rugoso-punctate, the 

 parapsidal grooves deep and foveolate, and the scapulae along their 

 inner margins transversely striated. The scutellum and axillae are 

 rugoso-punctate, the scutellum with a broad shallow depression medi- 

 ally and with a distinct transverse fold before the apex but without 

 distinct lateral grooves. The propodeum is longer than the hind 

 coxae, nearly uniformlj^ rugoso-punctate, but with a shallow depres- 

 sion along its anterior margin, this depression divided by a short longi- 

 tudinal carina on the median line and crossed by numerous more or 

 less longitudinally directed rugae. The mesepimeron is sculptured on 

 its upper half as well as on the lower half. The abdominal petiole, 

 viewed from above, is about twice as broad as long, as long as hind 

 coxa, margined by a longitudinal carina on each side, and very weakly 

 sculptured dorsally. The gaster is rather large, smooth and polished. 

 The second sternite is polished with its apical suture foveated.
