VIII, D, 4 Craivford: Psyllidse from the Philippines 297 



elude it in this genus because of the unquestionably close relation- 

 ship in all other respects. In P. depressa Crawford the cubital 

 petiole is very short, approaching the condition found in the 

 present species. This is only another bit of evidence showing 

 that too much importance has been ascribed to such venational 

 characters. 



Pauropsylla triozoptera setifera var. nov. 



Corresponds very closely with the species in nearly every 

 respect except the following. Veins of forewing set with con- 

 spicuous setse; often all of the veins setigerous, but sometimes 

 only a part of them. Dorsum of thorax more pubescent than in 

 the species. Claspers of male stouter and larger. Male in some 

 cases very light colored and the female sometimes dark. 



There seems to be more or less gradation in the number of 

 setse on the wing veins. In some specimens of the species there 

 may be seen a very few widely scattered hairs, but usually the 

 veins are entirely without them. However, in some specimens 

 of the variety the number is reduced, but never to such an extent 

 as in the species. 



Described from 3 males and 4 females collected on the leaves, 

 of Columbia serratifolia DC.,^ Los Bafios, P. I. (Baker) . 



Epipsylla pulchra sp. nov. (Plate I, figs. D, G, K, 0.) 



Length of body, 2.3 mm. ; length of forewing, 3.1 mm. ; width 

 of head with eyes, 0,93 mm. General color light reddish brown, 

 with 2 conspicuous white stripes bordered narrowly by black 

 extending from the tip of genal cones along vertex and notum 

 and uniting on metascutellum ; another similar short stripe from 

 each posterior ocellus to antennal insertion; a third pair on 

 under and outer side of cone beneath antennal insertion. Body 

 surface covered sparsely with stiff black hairs. 



Head about as broad as thorax, moderately long, somewhat 

 deflexed ; vertex fully half as long as broad between eyes, slightly 

 depressed along each white stripe; cones only slightly longer 

 than vertex, divergent, subacute, porrect, pubescent. Antennse 

 about twice as long as body without wings, very slender, segment 

 VIII longest. 



Thorax arched ; propleurites very narrow, as in Psylla. Legs 

 slender, wings membranous, rounded at apex, two and a third 

 times as long as broad, light brown throughout; veins slightly 

 setigerous; pterostigma wanting.
