PARARILEYA new genus. 
Female :—Like Neorileyella except that the abdomen has segment 5 much lengthened, 
longer than half of the surface, the others short, transverse. Postmarginal vein a little longer 
than the stigmal. The axille are distinctly separated. Stigmal vein straight. The umbilicate 
punctures are shallow and not dense, the thorax finely reticulate. Caudal margin of pronotum 
straight, the pronotum as long as the scutum. The parapsidal 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. Genotype. 
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 with 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. Axille 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.

Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 8281, 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 
TIsosomini 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.
