Among a small collection of Micro-Hymenoptera kindly lent me by Mr. W. 

 W. Froggatt, Government Entomologist of New South Wales, the two species 

 described herein were picked out as new ; of these one is of special interest, being 

 a primary parasite of the Sheep-Maggot Flies. 



I am very miii^h indebted to Mr. Froggatt for the loan of the sjjecimens. 

 and also for the data and information contained in his lettei-s. 



Family DIAPRIIDAE. 



Hemilexomyia, n. gen . 



?• — In Kieffer's table of genera (Genera Insectorum, 1911), running to 

 Uemilexis Foerster, Paramesius W^estwood, and Spilomicrus Westwood; closely 

 related to all these genera and combining many of their characteristics, but at 

 once differing in the incised base of the body of the abdomen, and the very 

 long stigmal vein ; Uemilexis and Spilovucrus possess a more or less truncate 

 abdomen at the apex, but in botli the.se the base of the body of the abdomen is 

 distinctly raised from the petiole, whereas Paramesius, which does not possess 

 the latter character, has the apex of the abdomen narrow and pointed. The 

 detailed generic characters are given in the description of the species. 



Type, Hemilexomyia abrupta, n.sp. 



Hemilexojivia abrupta, n.sp. 



?. — Length, 5.5 mm. Shining black; legs, including the coxae, bright red; 

 antennae red, the apical half more or less dusky; tegulae red. 



Head normal ; smooth and shining, except for scattered small punctures 

 each bearing a long fine seta; viewed from above, sub-rectangular, about twice 

 as wide as long; viewed from the side, the frons triangular, the antennal prom- 

 inence distinct; cheeks broad; eyes moderately large, giving off a few long setae; 

 ocelli large, close together. Antennae inserted on a prominence in centre of 

 frons, 13-jointed; scape long and slender; pedicle and flagellar joints with scat- 

 tered long pubescence; pedicel twice as long as its greatest width: flagellum 

 without a distinct dub, the apical seven joints a little thickened; joint 1 cylin- 

 drical, one-half longer than pedicel (in two specimens from ]\Iarsden longer and 

 twice as long as pedicel) ; joint 2 one-half as long as 1; joints 3 and 4 subequal,
