1925] New N emestrinidce from Rhodesia and New Guinea 19 
A medium-sized, robust, brown black species, covered with 
a dull, reddish brown tomentum; legs and antennae testaceous. 
Pilosity brownish grey on head and thorax; abdomen almost 
destitute of hairs. Wings long, deeply bisinuate along the 
posterior margin, deep reddish brown; an elongate and narrow 
hyaline streak in the fourth posterior cell and faint indications 
of hyaline in the center of the combined first and second posterior 
and of the second basal cells. 
Male. Integument apparently black, though the body is so 
uniformly covered with tomentum that it is difficult to see the 
proper color. Antennae and legs pale testaceous; coxae more 
brownish; apical half of claws brownish black. 
Head and thorax with abundant, long, erect, brownish 
grey pilosity, which is denser on the ventral side. Hairs of the 
abdomen very short and sparse, dark grey; somewhat more 
abundant and longer ventrally and on the sides of the second 
tergite. Coxae and femora with moderately long, reddish grey 
hairs; the pilosity of tibiae and tarsi much shorter, but of the 
same color. Head, thorax, and abdomen are covered with a dull, 
cinnamon red bloom. There are no traces of dull stripes on the 
thorax nor of spots on the abdomen; but the second tergite 
bears close to its base a deep, transverse groove, which is shiny 
except on the middle; in addition there is a short, transverse, 
shiny depression on the side of each of the tergites 2, 3, 4, and 5. 
Head large, much flattened, a little broader than the thorax; 
semi-elliptical in profile and from above; kidney-shaped and 
nearly twice as wide as high when seen in profile. Front nar- 
rowly triangular, widest at the antennae where it measures about 
one-half the width of the eye; the inner orbits strongly converging 
above, where they come extremely close together for a short 
distance below the anterior ocellus, though not actually touching. 
Vertex triangular. Ocellar protuberance quite prominent, short, 
deeply divided behind from the inner orbits which project a 
considerable distance beyond the occipital margin of the vertex. 
Ocelli large, of about the same size, placed in an equilateral 
triangle. Eyes bare, composed in their upper half of large facets 
which gradually merge into the much smaller ommatidia of the 
lower half. Antennse (Fig. 2a) very small, placed a short dis-
