scutellum dirty white or yellowish; antennal segments 3 to 8 
dark at apex and light basally, 9 and 10 black ; forewings opaque, 
brown, small area at base and another at tip whitish, veins 
tawny; between the veins rows of many, small, light-colored 
patches, giving a very striking and characteristic appearance 
to the wings. Body surface sparsely covered with rather long 
hairs. 
Head short, not as broad as thorax, much deflexed, hairy; 
vertex roundly convex, without foveal impressions, scarcely ele- 
vated at posterior ocelli ; frons scarcely visible ; front ocellus not 
visible from above, close to clypeus; gense small, somewhat 
swollen beneath each antennal insertion, without cones. An- 
tennae twice as long as width of head, slender. 
Thorax broad, robust, hairy. Legs rather short; front and 
middle pairs of tibiae conspicuously flattened and somewhat fo- 
liaceous and front femora somewhat flattened in distal half; 
hind tibiae with a large, prominent tooth near apex. Forewings 
coriaceous, not flat but somewhat convex, broadly rounded at 
apex; venation very singular and characteristic; pterostigma 
shaped like a marginal cell ; radius much contorted, second mar- 
ginal cell long and narrow and parallel with posterior and apical 
margins of wing. 
Abdomen about as long as thorax. Female genital segment 
short, about one-fourth as long as abdomen ; dorsal valve a little 
longer than ventral, both slender and acute at tip, dorsal valve 
with an acute epiphysis at apex.

Genus HETEROPSYLLA Crawford 
This American genus, comprising seven described species, is 
a well-marked group. One species apparently abundant in the 
South Pacific is closer to this genus than any other. Although 
it differs in some important characteristics from the American 
species, it is nevertheless included herein for the present.

Length of body, 2 millimeters; length of forewing, 2.1 ; length

eral streaks on thoracic dorsum white or pale; two longitudinal 
rows of white spots on each side of abdomen. Body surface
