light brown with darker streaks on dorsum; venter of thorax 
pale whitish with a few brown streaks; abdomen mostly dark 
brown; antennae and legs light yellowish brown; wings clear. 
Head strongly declivous, not as broad as thorax. Vertex 
somewhat quadrate in outline, nearly perpendicular to axis of 
body, nearly as long as broad, median suture not visible, sur- 
face without depressions, broadly convex and not flat, front por- 
tion extended forward between antennal bases. Frons small, 
visible from in front. Gense slightly swollen beneath antennal 
sockets. Antennae short, about as long as width of vertex 
between eyes, with three long setae at end of each. Eyes large, 
recessive. 
Thorax broad, well arched. Legs rather slender; hind tibiae 
without basal spur. Forewings hyaline, clear, narrowly rounded 
at apex, veins narrow, yellow ; pterostigma narrow, radius short ; 
first marginal cell (in both forewings of the only specimen at 
hand) divided transversely across the middle. 
Female genital segment nearly as long as abdomen, rather 
slender, dorsal valve a little longer than ventral, with a serrated 
carina along apical dorsal portion; both valves acutely pointed. 
Tenimber Islands, Larat {Muir), 1 female. 
This species is remarkable because of its vertex, which is with- 
out a visible median suture. The divided marginal cell of fore- 
wing is probably not a constant specific character but only an 
abnormality. 
Pauropsylla apsylloides sp. nov. Plate I, fig. 7. 
Length of body, 2.9 millimeters ; forewing, 4.2. General color 
light to dark brown, sometimes with dirty brown blotches on 
thoracic dorsum; eyes dark; forewing clear, with four brown 
spots on posterior margin and one at apical end of pterostigma. 
Body large and robust; surface reticulately marked. 
Head strongly declivous, not quite as broad as thorax. Ver- 
tex nearly perpendicular to axis of body, about three times 
as broad as length down median suture, arcuately concave on 
posterior margin; frons visible between gense, with large front 
ocellus at apex ; clypeus large, visible below frons. Gense 
swollen beneath antennal sockets. Antennse about as long sis 
width of vertex between eyes, sometimes a little longer, relatively 
thick, segments short and terminal setse rather short. Eyes 
large, recessive over propleurites. 
Thorax very broad and robust, strongly arched, and finely 
reticulately marked. Legs short and thick; hind tibise short, 
without basal spur, four thick, black spines at apex within.
