[September 
1 have seen no specimens of this species, but Emery’s 
figure and description show that it is very closely related to 
S. opaca sp. nov., described below. Emery’s measurements 
are probably too low (‘‘2%-3 mm.”), and in his figure, the 
eyes may be portrayed as much too flat, judging from other 
related species. In the width of the head, form and pilosity 
of the antennal scapes, and other features, this species and 
S. opaca together form a subgroup distinct from the other 
szalayi relatives. Possibly wallacei, like opaca, may also 
lack the intercalary tooth of the apical fork. Of ivallacei, 
Emery says the gaster is “nitida, nigra, basi rugosi-striata.” 
In the new species, the entire first tergite is sculptured and 
opaque, and is deep red instead of black. As already men- 
tioned, the difference in the eyes as portrayed in Emery’s 
figure may not be reliable, so we shall have to await an 
opportunity to see types of ivallacei before citing other dis- 
tinctions between the two species. The types are either 
in the Emery Collection, Museo Civico di Storia Naturale, 
Genoa, or in the Hungarian National Museum, Budapest, 
or both. Type locality: Lemien Forest, near Berlinhafen, 
New Guinea. 
Slrumigenys opaca new species 
Holotype worker : TL 3.49 mm., HL 0.83 mm., ML 0.46 mm., 
WL 0.81 mm.; Cl 86, MI 55. Occipital lobes overlapping pro- 
notum by about 0.04 m., this amount not subtracted from 
TL. 
Head in outline very much as in Emery’s figure of S. 
wallacei (see above), very broad and similarly deeply ex- 
cised posteriorly. Eyes larger, more convex and more 
strongly protuberant, also more anteriorly directed, than 
those shown for ivallacei in Emery’s figure. Actually, the 
eyes are situated on low protuberances, immediately in 
front of which run deep vertical preocular sulci ; the latter 
continue onto the ventral surface of the head and join there 
to form the deep postoral sulcus. Antennal scrobes ending 
abruptly above the eyes. As the head is seen in direct dorsal 
view, the dorsolateral borders run well inside of the ventro- 
lateral borders and are only very feebly indented at the 
level of the eyes. The periocular structure is similar to that 
of szalayi, niclifex, etc., but differs in having the dorsolateral
