On some Fijian Psyllidee. 553 
in metazona, impressed in the lower third of the prozona, with 
some short and low longitudinal carinulee between the trans- 
verse sulci which are scarcely developed but still perceptible. 
Elytra extending a little beyond the middle of the meta- 
notum, four or five times as long as at the base, broad, 
narrowed towards the rounded apex. Abdomen with a low, 
linear, median keel, Hind femora probably olivaceous in 
lite ; hind tibie pale brown (reddish in life ?). 
Length of body 14 mm.; pronotum 3 mm.; elytra 1-5 mm.; 
hind femur 8°5 mm. 
The type is labelled “Mt. Everest Exped. Up to 
18,500 ft., July, 1921.” It is in the British Museum 
collection. 
The exact systematic position of this curious insect is not 
yet clear, It evidently has nothing to do with Conophyma, 
which it resembles so closely at first sight, because it has no 
outer apical spine of the hind tibis, and belongs therefore to 
another division, The absence of the prosternal spine seems 
even to indicate that it is a member of either Acridinze 
(=Truxalinz) or Locustinee (=CE&dipodine), but I am more 
inclined to include it in Catantopinee judging by all other 
characters, though a definite solution may be arrived at only 
after the male sex is described. 
It is a great pity that only one specimen has been brought 
by the Expedition, though the insects are undoubtedly not 
uncommon on the Alpine pastures. It is worth drawing the 
attention of all future collectors on high altitudes in Central 
Asia that their Orthopterous fauna is wholly unexplored, and 
collecting of small, wingless, larvee-like grasshoppers 1s 
especially desirable, as they are usually strictly localized, and 
their extensive study may throw some light on the origin and 
history of the Palssarctic fauna.

Turoven the kindness of Dr. G. A. K. Marshall, Director 
of the Imperial Bureau of Entomology, I have been able 
to examine a collection of Psyllide from Fiji. Three un- 
described species appear to be present, and descriptions of 
them are given herewith.
