here is a distinct interruption the between submarginal and stigmal veins; 
stigmal, marginal and postmarginal vein, have not distinct borders 
and are only indicated by the pigment. 
Wings somewhat dusky, without white 
bands and witha small irregula rfascia be- 
neath of the submarginal vein. Antennae 
light brown. In other respects similar to 
the female. 
Habitat. One female and four males 
were reared from Æriococcus greeni on 
Agropyron repens at the Poltava Experi- 
ment Station. 
In Dr. G. Mayr’s table of the 
species of Encyrtus the species in question 
would run to 12, where it ought to be 
placed next chalcostomus Dalm., from 
which it differs by the broader vertex 
and darker colour. 
Fig. 5. Encyrtus subapterus, Encyrtus breviventris, sp. nov. 
sp. n. d and 9. Mandible of 
the male and antennae of both 
sexes. 
Female. Length 0,5 mm. Head round, 
vertex moderately broad; scape of anten- 
nae not dilated. Antennae slender, pedicel 
about as long as first three funicle joints together; each funicle joint 
longer than broade. Threejointed club as long as four preceding funicle 
joints combined. Abdomen short. Wings‘ light brownish; venation si- 
milar to that of the preceding species. 
Dark brown; pedicel, funicle and club of antennae uniformly pale 
brown; the veins of the wing brow- 
nish; trochanters, knees, tibiae at 
apex and tarsi testaceous. 
Male. Length 0.6 mm. Man- 
dibles distinctly four-dentate, as 4, 
it was observed on one dissected IRIS ox 
specimen. Flagellum with long hairs; 
first and second funicle joints as 
long as broade, the rest longer than 
wide; pedicel about times two and a half as long as first funicle joint. 
Club unjointed. 
Habitat. One female and two males were reared from Eriococcus 
greeni on Agropyron repens at the Poltava Experiment Station. 
In Dr. Gr. Mayr’s synoptic table of species of Encyrtus this 
species would run to 35. Butit does not seem to be closely allied to either of
