xv, 2 Crawford: Jumping Plant Lice 145 



Forewings very large and broad, hyaline, clear, acutely pointed, 

 veins slender; marginal cells very large; pterostigma elliptical, 

 radius short. 



Abdomen thick and short. Male genital segment short; for- 

 ceps as long as anal valve, slender, not much bowed outward, tip 

 slightly enlarged and provided with a short, downwardly and 

 inwardly directed point. Anal valve slender, apical third in- 

 clined caudad and tubular in shape. Female genital segment 

 longer than abdomen, much narrower and acuminate, dorsal 

 valve a little longer than ventral and both acutely pointed. 



Tenimber Islands, Larat (Muir), 1 female. Borneo, San- 

 dakan (Baker), 1 male. Southern China, Macao (Muir), 1 

 female. Hawaii, Oahu (A. Koebele), 1 imperfect specimen ap- 

 parently of this species. The last was no doubt an immigrant, 

 perhaps taken on some recently imported plant. It appears not 

 to have become established on this island as it has not been 

 again taken in subsequent collecting during many years. 



The male specimen differs from the others in being darker 

 colored and in having the antennse nearly as long as width 

 of head including the eyes, the basal tarsus of hind legs a little 

 longer, and the cubital petiole (M -f- Cu) longer than the stem 

 of the cubital vein, while in the females it is shorter. Whether 

 or not these are specific differences can scarcely be determined 

 until examples of both sexes from each locality are available 

 for study. 



This insect is somewhat suggestive of Apsylla cistellata, an 

 Indian species, but seems to be closer to Pauropsylla than to 

 Apsylla. 



Pauropsylla udei Riibsaamen. 



Pauropsylla udei Rubsaamen, Ent. Nachrichten 25 (1899) 262-266. 

 Pauropsylla bakeri Crawford, Philip. Journ. Sci. § D 10 (1915) 258. 



Length of body, 2 millimeters ; length of f orewing, 2.6 ; length 

 of antennae, 1. General color dark reddish to chocolate brown; 

 antennse, legs, ventral portion of gense, and genital segment 

 orangS yellow or paler; eyes pale; wings clear. Body robust. 



Head short, defiexed, not as broad as thorax; vertex reticu- 

 lately marked, elevated at posterior ocelli, extending forward 

 between antennal bases and covering frons, inclosing anterior 

 ocellus so that latter appears to be on vertex; frons scarcely 

 visible; gense swollen beneath antennal bases, without cones; 

 clypeus small. Eyes rather large; front ocellus near posterior 

 ocelli and visible from above. Antennse a little longer than 

 width of head, slender.
