 somewhat advanced. Abdomen a little wider and scarcely 

 longer than the thorax ; with fine dense reticulation. 

 Mandibles tridentate. Forewings long; broad, the apex 

 broadly rounded ; hyaline ; marginal cilia short ; discal cilia 

 normal; postmarginal vein hardly shorter than the stigmal. 

 Antennae 10-jointed, scape, pedicel, three ring, two funicle, 

 and three club joints ; first two ring joints small, the third 

 larger; pedicel scarcely longer than funicle 1, which is 

 distinctly longer than wide, 2 little yet distinctly shorter, 

 slightly longer than wide ; club joints a little shorter, 1 and 

 2 a little wider than long. 



Hab. — Queensland: Cairns district (one female reared 

 from its pupa embedded in mid-rib of leaf of sugarcane, June, 

 1915, A. P. Dodd). 



Type. — A female on a tag, antennae and forewings on 

 a slide. 



Closest to douglassi, Girault, but that species has yellow 

 on the face, and the facial structure is different. Of the 

 species of AchrysoehareUa, Girault, approaching nearest to 

 olymjms, Girault, and mackai/ensisj Girault; differs from the 

 former in having funicle 2 shorter than the pedicel ; 

 mackayensis is only half the size of this species, but the 

 description agrees very well, though the species in question 

 is said to bear two ring joints. 



ACHRYSOCHARIS. 



A small species of this genus, related to brevicornis, 

 Girault, foersteri, Girault, and nigripes, Girault, reared from 

 stems of cow- pea badly infested with Agromi/za phaseoli, 

 Cairns district, September, 1915, A. P. Dodd. The species 

 is possibly a hyper-parasite.
