Genus PARANAGRUS Perkins. 



" Paranagrus, gen. nov. 



Like Anagrus, but more slender and elongate, and with the third joint of 

 the antennae in the female elongate, not much shorter than the following and 

 quite slender. Otherwise as in the preceding genus. Ovii)ositor either slightly 

 or strongly exserted behind the abdomen. Antennae of male 13-jointed, as in 

 Anagrus, but with the third joint slender and elongate, as in the female. (Plate 

 XII, fig. land 2.) 



Parangriis ojjtabilis, sp. nov. 



Male ; flavous, head more or less sordid or smokj^ ; a large elongate sub- 

 triangular spot on either side of the middle line of mesonotum, the apex of these 

 spots reaching nearly to the scutellum ; a spot usually triangular on the 

 parapsides, and one on the axillae, dark; abdomen with at least the apical 

 segments more or less dark, blackish or fuscous; all the joints of the flagellum 

 smoky or fuscous. 



Female, like the male, but with the thoracic markings generally much 

 fainter, though occupying the same positions ; spots on the axillae sometimes not 

 discernable, the abdomen not dark on the apical segments. Length f mm. 



Hab: Queensland; bred in all localities from the eggs of PrrJ.insiclla 

 saccharicida. A very similar form inhabits Fiji, but the material is insufficient 

 to determine whether they are specifically identical. 



Paranagrus perforator, sp. nov. 



Female ; yellow or orange red ; head subinfuseate, the whole of the 

 flagellum of the antennae, two long triangular spots on the mesonotum, nearly 

 or quite reaching the scutellum, one on the front angles of each of the parapsides. 

 another on each of the axillae, an interrupted band on the first abdominal 

 segment, and an entire one on the second and third, the lateral margins of at 

 least some of the apical segments, and the sheaths of the ovipositor, dark, blackish 

 or piceous. Ovipositor extending w\41 behind the abdomen, for a length equal to 

 that of all the joints of one of the hind tarsi taken together. Length f mm. 



Hab : Fiji, bred from eggs of Delphaeid leaf-hoppers." 



The place of deposit of the types is unknown to me. 



POLYNEMA REDUVIOLI Perkins. 



" Polynema, Hal. 



The single species here described under this genus has a shorter marginal 

 vein than any of the others dealt with in this paper, but it is less punctiform 

 than in some other species, that I have examined. 



Polynema rcduvioli, sp. nov. 



Third and ten following joints in the male elongate, subequal, in the 

 female the third, fourth and fifth are very slender and elongate the following 

 three much shorter and wdder, the club about as long as the three preceding
