This species is so weakly vibrissate on the abdomen that 

 it might be referred to the subgenus P seudaugochloropsis , 

 falling in Vachal's tables near the Mexican A.tonsilis 

 (Vaclial). In Schrottky^s table of Brazilian species it falls 

 ill the vicinity of the much larger A. hecuba, Schrott., A. 

 circe, Schrott., A. brasiliana, Ckll., and A. monochroa, Ckll. 

 The two latter are very well vibrissate. The most distinctive 

 feature is the sculpture of the metathorax. The type of 

 Augochlora seems not to have been fixed; I will herewith 

 designate A. pura, Say *. 



Augochlora (Augochloropsis) semilata, sp. n. 



? . — Length about 7 mm., anterior wing 5. 



Brilliant emerald-green, including the legs except the 

 dark reddish tarsi; head very broad; clypeus prominent, 

 with large punctures, its lower margin broadly black ; 

 labrum black, with fine transverse lines and a pair of apical 



* I wished to designate A. pandora, Smith, the first species in Smith's 

 series described from the female, but in Canad. Entom. 1897, p. 4, I 

 restricted ^wr/oc/i/orrt, s. str., to a different series, and inchided in it two 

 of the species iu Smith's original list — jnira, Say, and labrosa, Say. 

 I choose of these the better known. This will make Oxystoylossa a 

 synonym o? Augochlora.
