black; mesosternum and legs, except tibiae and hind femora, 

 yellowish brown ; surface of vertex and thorax finely reticulated. 



Head nearly as broad as thorax, short ; vertex convexly rounded 

 downward, very finely pubescent, with posterior ocelli somewhat 

 elevated ; f rons mostly covered by gense ; antennae a little longer 

 than width of head, slender ; terminal setae short. 



Thorax thick and very robust as in congeners, but pronotum 

 and prosternum much smaller and partly covered by mesothorax ; 

 legs moderately long and slender; wings large, hyaline, nearly 

 half as broad as long, broadest subapically; first marginal cell 

 twice as large as second. 



Abdomen rather short and thick; female genital segment not 

 quite as long as rest of abdomen, subacute at apex ; dorsal valve 

 a little longer than ventral. 



Described from one female, collected on Mount Maquiling, 

 Luzon, P. I. (Baker). This is very close to an Indian (Ben- 

 galese) species, Pauropsylla depressa Crawford.- 



Pauropsylla floccosa sp. nov. Plate I, fig. j. 



Length of body, 0.9 millimeter; length of forewing, 1.2 ; width, 

 0.4; width of head, 0.25. General color light brown, with 

 lighter spots and streaks; legs lighter colored. A very small 

 species. 



Head as broad as thorax, short; vertex rounded down in 

 front, but less evenly so than in some congeners, with posterior 

 ocelli not much elevated; frons, with its ocellus, visible as a 

 small, narrow sclerite to clypeus ; antennae somewhat longer than 

 width of head, slender; terminal setae much longer than two 

 terminal segments. 



Thorax moderately robust; legs relatively rather long and 

 slender;. wings hyaline, with a whitish tinge, brownish in apical 

 half, rather small, broadly rounded, about twice as long as broad ; 

 veins spotted with brown ; venation somewhat similar to that of 

 P. tuberculata Crawford, a Bengalese species, but the first mar- 

 ginal cell is much larger relatively. 



Abdomen small; third and fourth tergites rather prominent. 

 Male genital segment small; forceps relatively long and slender, 

 as long as genital segment ; anal valve as long as forceps, larger, 

 simple. Female genital segment nearly as long as rest of ab- 

 domen, acutely pointed at apex. 



Described from 17 males and females collected at Peradeniya, 

 Ceylon {Rutherford), on leaves of Aglaia roxburghiana. "The 

 leaf is inrolled along the edge from below upward. The nymphs
