17,4 Crawford: The Psyllide of Borneo 357 
Trioza papillata sp. nov. Plate 1, fig. 3. 
Very obviously related to T. insula but quite different in 
several respects. Insect much smaller, body, about 1 millimeter 
long; forewing, 2 millimeters long. Vertex as in related form, 
extending forward in front of front cellus; genal cones small, 
fingerlike or nipplelike in shape, separate at base and slender, 
acute. Antenne black, twice as long as width of head. Legs 
small and slender. Forewings similar to 7. insula in shape and 
venation, but smaller and without brown band. Female genital 
segment about as long as rest of abdomen, acute at apex. 
BORNEO, Sandakan (Baker), 1 female. 
Megatrioza asiatica Crawford. 
This tropical Asiatic species appears to be present in Borneo, 
being represented in C. F. Baker’s collection by four specimens 
which closely resemble specimens from other regions. These 
were taken at Sandakan, Borneo. 
Megatrioza eugenioides Crawford. 
This species appears to be rather widely distributed in trop- 
ical Asiatic regions. Several additional specimens have been 
taken by Baker at Sandakan, Borneo. 
Megatrioza grandis sp. nov. Plate 1, fig. 1. 
Somewhat similar to M. gigantea Crawford, but longer and 
slenderer. Length from head to tip of folded wings, 8 milli- 
meters or more. Orange to light brown, few or no markings 
on body; legs and antennz concolorous, wings slightly fuscous. 
Genal cones shorter than vertex, broad and rounded, sparsely 
hairy. Antennz nearly twice as long as width of head, slender. 
Thorax long. Legs long, rather stout; hind tibie with large 
spur at base and three short spines at apex. Forewing very 
long, three times as long as broad, subacute at apex; upper 
fork of media terminating at wing tip; cubitus forked distad 
of mid-point. Hind wings about half as long as forewings. 
Male forceps nearly as long as anal valve, slender, curved, 
with a fringe of hairs on posterior margin; anal valve broad, 
posterior margin bulging caudad, with a fringe of long hairs. 
BORNEO, Sandakan (Baker), 1 male.
