The holotype, from Lichtwardt’s collection, is now at 
the Deutsches Entomologisches Institut, Berlin-Dahlem, 
where I have seen it. 
At the British Museum there is a specimen from Kolaw, 
S. Shan States, 4,000 ft. (F. M. Markwood Collector), which 
is possibly the undescribed female of H. basalis. 
Subgenus Hyrmophlaeba Rondani 
Hirmoneura (Hyrmophlaeba) laotica, new species 
Male. — A large, thickset fly, similar in appearance to 
H. obscura and most Oriental species of the genus, though 
not closely related to any of them. 
Integument of head, thorax and base of abdomen black; 
scutellum and juxta-alar tubercles dark brownish, the 
swollen margin of the scutellum bright ferruginous; an- 
tennae (except style), palpi, proboscis and legs (except 
hind coxae) , bright yellowish-red ; sides of second and most 
of succeeding tergites, most of the sternites and terminalia 
ferruginous-brown. Pruinosity uniformly dull gray, with- 
out markings or spots on thorax and abdomen; that of 
frons more yellowish; between the first and second tergite 
there is a narrow band of ashy-gray pruinosity. Body 
densely and uniformly covered with rather short, pale 
yellowish, erect hairs, longer on the head and on the sides 
and under side of the thorax; those below the base of the

with the yellowish on the frons; first and second antennal 
segments densely covered with long, pale yellowish hairs. 
Hind femora and tarsi with short, appressed, bright rufous 
pilosity. 
Head (Fig. 3B) large, hemispherical in profile, about as 
high as wide seen in front, not broader than the thorax. 
Eyes uniformly covered with short, yellowish-gray hairs, 
contiguous over most of the upper half of the frons. Ocel- 
lar triangle long and narrow, divided about midway by a 
transverse, saddle-like depression. Antennae (Fig. 3C) 
small, crowded together; first segment about three times 
as long as the second, slightly swollen throughout; second 
segment very short, transverse; third segment flattened, 
pear-shaped, only slightly longer and not broader than the
