Synplasta. Skuse, Proc. Linn. Soc. N. S. Wales (2), Vol. 5, p. 629 (1890). 
Characters. — Head roundish, the fore part compressed, situated deep in the thorax; front 
broad, the anterior border only very slightly produced in the middle; eyes longish round; ocelli two, 
tolerably large; palpi promnient, incurved, four jointed, first joint very small, second short, robust, 
third about twice the length of the second, fourth very slender, about equal in length to the others 
combined; antennae porrected, somewhat arcuated, 2 -|- 14 jointed, joints of the scapus cupuliform, the 
second slightly larger than the first, somewhat setiferous at the apex; flagellar joints somewhat com- 
pressed from the sides, densely covered with a minute downy pubescence. Thorax ovate, highly arched, 
densely covered with a short pubescence; lateral and hind borders setiferous; scutellum semicircular, 
setiferous. metanotum steep. Abdomen slender, in the male with six, in the female with seven segments, 
narrowed at the base, subcylindrical, a little compressed from the sides, anal joint of the male large, 
ovipositor of the female short, with two elongate lamellae. Legs long and slender, intermediate and hind 
femora rather broadly compressed, tibiae spurred and having lateral spines, fore pair without spines, 
intermediate pair with a range of small spines on the outerside, hind pair with two ranges of tolerably 
long spines on the outerside, metatarsus of the hind tarsi with minute prickles. Wings longer than the 
abdomen, oblong, with moderately rounded base, microscopically haired in longitudinal rows. Subcostal 
vein very short, bent posteriorly, ending in Rj ; costal vein extending slightly beyond the tip of the 
radial sector; media with a short petiole, its fork situated immediately below the basal section of the 
radial sector; branches of the cubitus not divergent, the base of its fork slightly proximad of the base of 
the fork of the media; both anal veins incomplete, the second stout (PI. 6, Fig. 5). 
This genus is allied to Kxechia, but differs in the position of the fork of the cubitus; from Allodia 
it differs in having a stouter anal vein.
