AUSTRALIAN EYMENOPTEBA CHALCIDOIDEA, I.— GIB AULT. 
105 
Type: No. Hyl603, Queensland Museum, the foregoing specimen. 
The species is dedicated to Matthew Arnold. 
The characteristic of the genus is really the short marginal ciliation of, 
the fore wing which so far is not known to intergrade; that is to say, species 
of Oligosita heretofore known have never failed to have the ciliation long and here 
its shortness is correlated with antennal peculiarities. I must, therefore, consider 
the genus distinct until it is known to the contrary. 
Genus CENTROBIELLA Girault. 
1. CENTROBIELLA MAGNA new species. 
Male: — Length, 1-05 mm. Large and robust for the family. Deep 
golden yellow, the wings hyaline, the sides of thorax and five conspicuous 
stripes across the abdomen from base to tip, jet black, the first three stripes of 
the abdomen fused in the dorsal aspect centrally. Marginal and stigmal veins 
conspicuously blackened, the stigmal knob enlarged and round, somewhat as in 
the Megastigminre but more rounded. Genitalia conspicuously exserted. Tibial 
spur of intermediate legs long, straight and slender, as long as the proximal 
tarsal joint of these legs which is moderately long. Differs from female muliernm 
in its much large]* size, the blackened marginal and stigmal veins, the enlarged 
stigmal knob, the greater development of the intermediate tibial spur and in 
bearing live abdominal stripes, the fifth one in muliernm being obscure, repre- 
sented by a spot at extreme apex; from the male of the same species in the 
same characters and also in having the conspicuously banded abdomen (merely 
darkened toward tip in male muliernm). Funicle joint longer than wide, stout 
Cephalic tibial spur very short and straight. Fore wings not very distinctly 
infumated proximad. 
Female : — Not known. 
Described from one male captured by sweeping grass and foliage in forest, 
August 5, 1913. 
Habitat: Nelson (Cairns), Queensland. 
Type: No. Hy 1604, Queensland Museum, the above specimen on a slide. 
OPHIONEURINI. 
Genus LATILROMEROIDES Girault. 
Differs from Tumidiclava Girault in having the abdomen very long and 
tubular, the club not much swollen and not terminating in a seta, the thorax
