Labellse wide and flat with circular, naked margins, proboscis 
slightly chitinized, dark brown, somewhat shrivelled in this 
specimen (Plate 1, figs. 1 and 2). 
Thorax compactly subquadrate, mesonotum convex with a 
transverse sulcus on caudal third, pilosity crenulate, worn on 
notum except laterad, where it is golden, a tuft of golden pile 
on mesopleuron cephalad of spiracle and another caudad of wing- 
base; scutellum lenticular, transversely striate, its lateral mar- 
gins circularly excised, its caudal margin with a broad elevated 
callosity, a fine crenulate golden pile just caudad of its margin 
on metanotum (Plate 1, fig. 6) ; abdomen as long as head and 
thorax, broadly oval in outline, segmentation prominent by rea- 
son of inflation of interstitial membranes; tergites brownish 
yellow, glabrous and with fine, black, scant, adpressed pile, worn 
off in patches, sternites as tergites, but paler glabrous and with 
much scantier pile; interstitial membranes with black pile; 
genitalia prominent, glabrous, brown (Plate 1, figs. 8 and 9). 
Legs normal, fore femora nearly as long as tibise and tarsi, 
mid femora slightly longer, hind femora as long as hind tibiae, 
all pale rufous brown with uniform, coarse, reddish brown or 
auburn pile, hind tarsi swollen basad and curved (Plate 1, 
fig. 7) ; fore and mid femora paler. 
Wings uniformly shaped and typically veined, longer than

Mindanao, Lanao, Kolambugan, Latitude 8° 10' north, longi- 
tude 123° 55' east. June 15, 1914, Charles S. Banks. 
This species falls naturally with H. annandalei Licht., and 
H. basalis Licht., because of its bare eyes, there being not a 
vestige of pubescence, even under the microscope. From H . 
annandalei it differs in size, in the color of the hairs, there being 
no “yellowish” abdominal hairs, in the color of legs and wings 
and in width of vertex and frons with respect to eye width. 
Another remarkable thing concerning this insect is that it 
was taken at sea level in latitude 8° 10' north, while those 
species recorded from British India come from altitudes of from 
3,000 to 9,000 feet, about 1,000 to 3,000 meters.
