355 



longer than the stigmal, the latter twice as long as the very 

 short postmarginal. Antennae 11-jointed; scape slender, also 

 the pedicel ; funicle joints about subequal, a little narrower 

 than pedicel, over twice as long as wide; club joints longer 

 than wide, the first a little the longest, a little longer than 

 last funicle joint. Ovipositor not extruded. 



Hab. — Northern Territory: Darwin (several females with 

 the variety brachyptera and hyaJ'tnipennis, and labelled 

 "From eggs of the Hemipteron, Megymenum insnlare, 

 27/4/15, G. F. Hill"). 



Type. — A female on a tag, two heads on a slide. 



brachyptera, n. var. 



9 . Like the typical form, but the wings aborted, mere 

 flaps ; anterior tibiae almost wholly yellow. 



$ Funicle joints much longer than the pedicel which is 

 short, the joints densely pubescent ; posterior tibiae yellow 

 also. 



Hab. — Northern Territory: Darwin (a large series 

 labelled as with the typical form). 



Types. — A female and male on a tag. 



Tetracnemella hyalinipennis, n. sp. 



9 . Length, 1'25 mm. Wholly dull dark green ; the 

 legs wholly clear golden-yellow ; abdomen with its ventral 

 basal half or more, and dorsad (except laterally), golden- 

 yellow; antennae wholly yellow, slightly dusky. 



Scutellum with much denser sculpture than the scutum. 

 Forewings hyaline. First funicle joint distinctly the shortest, 

 one-third longer than wide, 3-4 slightly the longest, barely 

 twice as long as wide ; pedicel fully twice as long as funicle 1 

 (not so in megymeni). Otherwise as in megymeni . 



d . Length, 1*10 mm. Abdomen merely suffused 

 yellow basally. Funicle joints pubescent, longer than in the 

 female, 1 somewhat longer than pedicel. 



Hab. — Northern Territory: Darwin (four females, one 

 male, labelled as in megymeni ). 



Types. — Two females on a tag, female and male heads 

 on a slide. 



Tetracnemella hemiptera, Girault. 



Ericydnus hemipterus, Girault. 



Closely related to megymeni. Girault has wrongly 

 placed the species in Ericydnus, to which genus it cannot 

 belong, since the axillae are widely separated.
