Psylla ccmpta sp. nov. Plate III, fig. 11. 
Length of body, 1.9 millimeters; forewing, 2.3; antenna, 3.5. 
General color orange; genal cones entirely white, pronotum pos- 
teriorly margined broadly with white, dorsulum on posterior 
margin narrowly margined with white and two white areas on 
mesoscutellum ; venter of thorax and dorsum of abdomen dark 
brown ; abdomen ventrad pale whitish ; legs flavous, except front 
tarsi brown; antenna brown except three basal segments orange; 
forewings, clear. 
Head strongly deflexed, nearly or quite as broad as thorax; 
vertex half as long as broad between eyes, elevated at posterior 
ocelli, with a very small foveal depression on each side of 
median suture, sparsely hairy, median suture scarcely impressed 
and narrowly black. Genal cones slender, conical, not quite as 
long as vertex, acutely pointed in apical half or third, closely 
appressed to each other, very briefly pubescent. Antennse very 
long, five times as long as width of head, segments 3 and 4 
slightly thicker than in most species. 
Thorax slightly pubescent; legs long, slender, hind tibiae with 
basal spur, distal spines numerous. Forewings clear, veins 
yellow or brownish, costal vein conspicuously hairy ; pterostigma 
narrow or wanting. 
Male genital segment moderately small, forceps small, about 
half as long as anal valve, slender, acutely pointed, simple; anal 
valve rather long, broadest at base and converging slightly to- 
ward subacute apex. 
Fiji Islands {Muir), 1905, 1 male and 1 imperfect example. 
The most characteristic feature of this pretty species is the 
form of the genal cones which is suggestive of the genus 
N eotriozella. 
Psylla muiri sp. nov. Plate III, fig. 5. 
Length of body, 2 millimeters; forewing, 2.1. General color 
chocolate brown with irregular and narrow white markings and 
stripes on thorax, vertex, and abdomen; legs light brown or 
femora darker ; antennae pale with apex of each segment darker ; 
forewings fumate or brown, with a dark spot at tip of clavus 
and three others on posterior margin. 
Head deflexed, not quite as broad as thorax, vertex roughly 
triangular in outline, half as long as broad, with a small pro- 
tuberance behind eyes on outer margin, a small foveal depression 
on each side of median suture and the two connected by a shallow 
transverse fossa. Genal cones scarcely half as long as vertex, 
narrowly rounded at apex, declivous from vertex, divergent;
