518 The Philippine Journal of Science 1921 
specimens in the Bureau of Science were being sorted that its 
true nature was discoverd, with considerable surprise, it must 
be admitted. Had I at the time realized what a real treasure it 
was, I should have been on the alert for more specimens:. As 
it is, we have but a single male, intact, but with much of the 
pubescence worn from the notum and tergum. 
Hirmoneura philippina sp. nov. 
Male large, robust, brown, pubescent, legs brownish yellow, 
with coarse, adpressed auburn pile ; wings uniformly semi- 
opaque brown, each longer than body. 
Head wider than thorax, slightly more than hemispherical, 
nearly holoptic, the face and vertex one-seventh of the head- 
width, sides of vertex converging slightly caudad in region of 
ocelli (Plate 1, fig. 3) ; eyes bare, red-brown with garnet reflec- 
tions, occupying nearly whole of head in profile ; occiput slightly 
convex near eye margins, dark tawny, pilose ; ocelli placed 
on two prominent tubercles separated by a shallow, wide, trans- 
verse sulcus, the anterior ocellus at cephalic margin of anterior 
tubercle, each posterior ocellus at lateral margin of posterior 
tubercle and contiguous with eye (Plate 1, fig. 3) ; vertex from 
region of ocellus, and face to buccal cavity bisinuous in profile 
and with black and tawny, semierect, silky hairs growing more 
tawny at antennae and continuing shorter along lateral margins of 
buccal cavity (Plate 1, fig. 1). 
Antennae stout, tawny, covered with heavy, tawny to golden 
bristles proximad, rather bare distad; of seven segments, first 
oval, three times length of second which is concave distad to 
receive segment 3, the latter being one-third longer and very 
broadly and bluntly fusiform; segments 4 to 7 form the style 
which is as long as segments 1 to 3 together, segments 4 to 6 
tawny, 7 opaque black-brown; segment 1 with heavy, tawny 
bristles, 2 with fewer scattered ones and 3 with an equatorial row 
of about seven stout black setae in addition to a very fine, closely 
adpressed golden pile; segments of style finely pubescent (Plate 
I, fig- 5). 
Palpi reddish tawny, long, erect, partially concealed in longi- 
tudinal sulci close to eye-margins, first segment subarcuate, 
second sinuate, slender, five-ninths length of first, entire palpus 
twice length of antenna excluding style, geniculate at base, 
strongly hairy on anterior margin, no hairs basad, hairs semi- 
erect, those on second segment pointing proximad (Plate 1, 
fig. 4).
