funicle. The genus is distinguished from Brachistella and AbheUa 

 by its very short marginal vein, and its long, slender stigmal. It 

 is gratifying to me to be able to throw light on this point. 



1. Neobrachista novifasciata n. sp. 



Female. — Length 1.00 mm. 



Closely allied with the type species, fasciafa Girault, but more 

 robust, the abdomen broader (a little wider than the thorax, 

 distinctly narrower in fasciata), and with but three black stripes 

 across it, one a little out from base, the second a little distad of 

 the middle, and the third a little distad of the mid-distance from 

 the second to apex. The first funicle joint is a little longer and 

 more distinct (yet not quite half the length of the second which is 

 a little wider than long; in the type species the first joint is only 

 about a fourth the length of the second which is a little longer 

 than wide). Second, black stripe of abdomen interrupted at the ^ 

 meson, the others continuous and straight. Mandibles tridentate. 

 Also the fore wings are shorter and broader, subtruncate at apex 

 (bearing about 26 lines of discal cilia across the widest point). 

 Fore wings slightly clouded, more distinctly under the 

 stigmal vein and along the venation. Thorax with a distinct 

 median sulcus (not present in the single specimen of the type 

 species before me though slightly indicated in places, nevertheless 

 plainly absent), as deep as the parapsidal furrows. 



Male. — Not known. 



Described from a single specimen captured v/ith the above 

 LathromereUa. 



Habitat. — Australia, Nelson (Cairns), Queensland. 



Type. — The above specimen on a slide with two 9 's of 

 LathromereUa fasciata Girault. 



Family MYMARID^. 

 Genus Polynema Haliday. 



1. Polynema zolai n. sp. 



Male. — Length 1.50 mm. Large. 



Jet black, the wings hyaline, the venation black, also the 

 antennae (but the pedicel brown) and the legs except the tarsi, 

 knees, tips of tibia:? and all of cephalic tibiae which are brown. 

 Characterized by the wings which are broad, subtranslucent and
