small and subpunctiform notauli, large and 
elongate metathoracic spiracles, the prom- 
inent petiolar spiracles, more deplanate ab- 
domen, very large but slightly curved tarsal 
claws, straight discocubital nervure, centrally 
strongly incurved second recurrent and gen- 
icular nervellus, which emits a very strongly 
sinuate nervure to apex of the wing. I will 
not include P, inflexa Motley in Poecilocryptus 
Cameron. 
Motley (1914: 36) describes some small 
specimens reared by Froggatt in 1892 from 
the swollen stems of Acacia leaves at Sydney, 
a male from Agrizon galls. Rose Bay, and a 
third specimen taken by French at Melbourne 
in 1900. 
These specimens Motley considered a va- 
riety of P. nigromaculata, as he states: ’T can- 
not regard as distinct a much smaller, clear 
stramineous form with the black markings 
very much sparser, the sides of the abdomen 
alone spotted and the legs immaculate: these 
modifications lend the insects a very different 
aspect, and the length is but 6-7 mm.; but 
the structure is in every way identical, and I 
will simply term it Var. stramineaP 
I have examined a series of a dozen spec- 
imens of this small form which Morley con- 
sidered a variety of P. nigromaculata Cameron, 
and consider it to be without doubt a distinct 
species. 
Although Morley stated that in structure 
it is in every way identical with P. nigromacii- 
lata, the specimens I have examined may be 
separated structurally from Cameron’s species 
thus: 
P. nigromaculata Cameron 
Postocellar space wider 
than the ocellocular space 
Antennae longer than 
fore-wing, with less than 
30 joints in flagellum 
Ovipositor not as long as 
the abdomen 
Length 9-10 mm. 
P. straminea Morley 
Postocellar space equal 
to ocellocular space 
Antennae shorter than 
fore-wing, with more than 
30 joints in flagellum 
Ovipositor always longer 
than the abdomen, some- 
times nearly IV 2 times as 
long 
Length 5-7 mm. 
On the above differences in structural char- 
acters, together with the constant differences 
in the distribution of the black markings on 
the abdomen. Motley’s variety straminea is 
given specific rank. 
KEY TO SPECIES of poecHocryptus 
1. Radial side of areolet about twice as long 
as upper inner side of areolet and as long 
as or longer than lower outer side 2 
Radial side of areolet equal to upper inner 
side and shorter than lower outer side of 
areolet. A crest or tooth at apex of denti- 
paral area. Spiracles of petiole before mid- 
dle P. nigripectus 
2. Antennae with over 30 joints in flagellum, 
shorter than length of fore-wing. Second, 
third, fourth, and fifth tergites of abdomen 
with lateral spots, more or less discrete. 
Ovipositor as long as or longer than ab- 
domen P. straminea 
Antennae with less than 30 joints in flag- 
ellum, and longer than length of fore- 
wing. Second, third, and fourth tergites of 
abdomen with wide basal transverse bauds 
of black, sometimes strongly incised me- 
dially, but usually not separated into dis- 
crete dorsolateral spots. Fifth tergite has 
a broad transverse band not incised me- 
dially. Ovipositor not as long as abdomen
