triangular on each side of median line with long side next to 
eye, prominently elevated at posterior ocelli, with median suture 
conspicuous and convex between antennal sockets and median 
suture, with an elongate sulcus distally on each side of median 
line; anterior ocellus scarcely visible from above; frons mostly 
covered by gense; gense very expansive, but not swollen, contin- 
uing to clypeus in nearly the same plane with distal portion of 
vertex. Clypeus moderately large, beak very long and prom- 
inent. Eyes very large. Antennse one and a half to two times 
as long as body without wings, very slender and threadlike, 
darker apically. 
Thorax broad, well arched; propleurites covered by recessive 
eyes, metascutellum elevated into a large, prominent epiphysis. 
Legs large, hairy; hind tibiae with spur at base and several 
spines at apex ; basal tarsus of third leg with two black spines 
at apex. Fore wings membranous, clear, with several (usually 
six) black or brown spots along posterior and apical margins; 
veins setiferous. 
Abdomen somewhat laterally compressed dorsad, and more or 
less triangular in transverse section, sharply angled above ; each 
segment with a dense fringe of hairs on posterior margin. Male 
genital segment not large; forceps not quite as long as anal 
valve, nearly as broad; anal valve long and slender, inclined 
toward forceps, truncate at apex. Female genital segment about 
half as long as abdomen, both valves subequal in length, acute, 
hairy. 
Tenimber Islands, Larat {Muir), December, 1907, 57 males 
and females. Moluccas, Amboina {Muir), January, 1908, 1 
male and 12 females. 
This differs from the other species of the genus in the larger 
size, longer antennae, armed hind tibiae, and epiphysis on meta- 
scutellum. The other species are American. An imperfectly 
preserved specimen from the Philippines seems to belong to this 
genus.

Nymph . — The nymph of this species is very large and robust, 
not flattened as in 'most psyllids but more cylindrical or saccate, 
the shape characteristic of most gall-forming species. Head 
very short, much narrower than thorax ; eyes not bulging, small ; 
antennae about as long as width of head, stout; clypeus large 
and prominent. Thorax nearly as broad as abdomen, legs short
