1 ? , Tssororo, N.W.D., Dec. 1918 {Bodkin). 



Previously knonn only by tlie unique type, from Frcncii 

 Guiana. The abdomen does not show the strong- coppery 

 tints of the type, but this variation is like that found in 

 related species. 



AugochJora {Oxystoglossa) eruhescens^ sp. n. 



? . — Length about 7 mm., anterior wing about 5'3. 



Head, thorax, and abdomen green, strongly suffused with 

 copper-red; the face (except the broad black lower margin, 

 of clypeus) entirely red, the clypeus and supraclypeal area 

 crimson j mesothorax and seutellum red, but meso])leura 

 yellowish green, reddish along its posterior border. Abdo- 

 men above brilliant red, with almost lilacine tints, becominjj 

 green at sides. Legs black, with the anterior tibiae and 

 tarsi, middle tibiae in front, hind knees^ and middle and 

 hind tarsi obscurely, ferruginous ; flagellum dusky reddish

 broad, posterior orbits reddened ; supraclypeal area closely 

 punctured, but shining; clypeus closely punctured, depressed 

 in apical middle ; front dull and greenish ; mesothorax: 

 shining but not polished, the microscope shows many very 

 small punctures and scattered much larger ones; area of 

 metathorax large, with fine radiating stride all over, these 

 wrinkled about the middle; posterior truncation not abrupt; 

 first recurrent nervure meeting second intercubital ; hind 

 spur simple (microscopically denticulate). Abdomen with 

 pale pruinose pubescence ; first two segments not vibrissatc, 

 but with extremely short fringes of branched hairs. 



Issororo, June 1915 (Bodkin). 



A distinct species, for which I find no very close relative, 

 but it may be compared with the much more brilliantly 

 coloured A. ignifera, Crawford, from Dominica. 



Augoc/dora [Augocfdoropsis) barticana, sp. n. 



$ . — Length about G*.") mm., anterior wing 5 or a little over. 

 Brilliant yellowish green, with golden tints on metathorax
