forewings extend to or a little beyond the apex of the first tergite. The 
males apparently are always fully winged but differ from typical 
Ooencyrtus by having the funicle of the antenna slightly compressed, 
the joints subequal, about as broad as long, narrower at base than at 
apex and clothed with relatively short hairs, none of which is longer 
than the segments. These differences do not seem sufficient to justify 
the erection of a new genus for the species, the habits of which agree 
with those of other species of Ooencyrtus. 
Fully winged female.—Length 1.6 mm. Head as wide as thorax, 
with fine, reticulate sculpture; eyes rather large, very sparsely pilose; 
ocelli small, forming a nearly right-angle dtriangle; ocellocular line 
slightly longer than diameter of lateral ocellus; width of frons equal 
to approximately one-third width of head; frontovertex about one and 
one-third times as long as broad; scrobes moderately impressed, 
rounded above; cheeks rounded; malar groove distinct but fine; mandi- 
bles each with three short subequal teeth; maxillary palpus four- 
jointed, labial palpus 3-jointed; antennae inserted near anterior mar- 
gin of face; scape compressed, about four times as long as broad, broad- 
est medially; pedicel subcylindrical, nearly three times as long as 
broad, about equal in length to first and second funicular segments 
combined ; funicular joints cylindrical or nearly so, the first joint just a 
little longer than broad and slightly narrower than pedicel; second 
joint subequal to first; third to sixth joints about as long as broad, the 
sixth slightly thicker than the first; club cylindrical, not thicker than 
funicle, about as long as three preceding funicular joints combined and 
distinctly 8-jointed. Thorax slightly compressed dorsoventrally; 
mesoscutum distinctly broader than long, weakly convex, weakly re- 
ticulated and with numerous small, shallow hair punctures; scutellum 
low, nearly flat, subtriangular, subacute at apex, a little longer than 
mesoscutum and with similar reticulate sculpture, but with sparser 
and less distinct hair punctures; whole dorsum of thorax somewhat 
shining; propodeum short, weakly reticulately sculptured, without 
distinct carinae; pleura more strongly sculptured and less shining 
than mesoscutum. Legs normal, spur of middle tibia about two-thirds 
as long as first tarsal joint. Forewing extending beyond apex of 
abdomen, a little more than twice as long as broad; marginal vein a 
little longer than broad, postmarginal longer than marginal but a 
little shorter than stigmal, which is about twice as long as marginal; 
marginal cilia short; discal cilia rather dense and short; oblique 
hairless streak behind stigma! vein wider posteriorly than anteriorly 
and complete. Abdomen as long as head and thorax combined, as 
broad as or a little broader than thorax, rather robust, ovate, weakly 
reticulately sculptured; ovipositor not exserted. Black, somewhat 
shining; antennae entirely black; all coxae, anterior and posterior
