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. Genae 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. 



Tenlmber 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 genae, with large front 

 ocellus at apex; clypeus large, visible below frons. Genae 

 swollen beneath antennal sockets. Antennae about as long as 

 width of vertex between eyes, sometimes a little longer, relatively 

 thick, segments short and terminal setae rather short. Eyes 

 large, recessive over propleurites. 



Thorax very broad and robust, strongly arched, and finely 

 reticulately marked. Legs short and thick; hind tibiae short, 

 without basal spur, four thick, black spines at apex within.
