PARARILEYA new genus. 



Femiile: — Like Ncorileydla exct>i,it that, the abdomen lias segment 5 much lengtliened, 

 longer than half of the surface, the others short, transverse. Postmarginal vein a little longer 

 than the stigmal. The axilliB are distinctly separated. Stigmal vein straight. The unibilieate 

 punctures are shallow and not dense, the thorax tinely reticulate. Caudal margin of pronotum 

 straight, the pronotum as long as the scutum. The ]iarapsidal furrows are present, delicate. 

 Abdomen distinctly scaly dorsad except segment 3 and apex of segment 2 broadly. Abdomen 

 with a short petiole, shaped as in the Eurytomini. 



1. PARARILEYA SPADIX new species. GenotyiJe. 



Female: — Length, 2.15 mm. 



Reddish brown, the wings hyaline, the legs and scape yellowish brown, the flagellum 

 dusky. Funicle 1 longest, subquadrate, the others gradually shortening, the pedicel a little 

 longer than funicle 1. Distal joint of funicle distinctly wider than long. Mandibles 

 4-dentate. Hind tibia w-ith two spurs. Propodeum with a somewhat W-shaped carina across 

 it running down each side like a lateral carina, curving along the caudal margin and then 

 cephalad to cephalic margin of propodeum at the meson where it makes an obtuse turn and 

 repeats on the opposite side; it is shaped like a W with the apex of the middle arm obtuse 

 instead of being acute. Axilhc rather widely separated. Abdomen finely scaly reticulated like 

 the thorax. Parapsidal furrows very delicate. 



From three females reared from cecidomyiid galls on a wild grape vine, April, 1913- 

 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. JJyJJSl. Queensland Museum, Brisbane, the above specimens on a tag. 



Species in this family as a rule do not shrivel. The present arrangement of the tribes 

 may break down by the too great instability of their characteristics. The Eurytomini and 

 Isosomini may, perhaps, have to be joined. The differences in their thoracic structure are 

 certainly not great and the habits of the two seem to be identical. It is, therefore, a 

 question as to the value of tribal groupings based upon secondary sexual characters. My 

 knowledge of the family, however, is not extensive and for the present I do not like to 

 interfere with the present arrangement other than to suggest its probable unnaturalness, more 

 especially as regards genera.
