in metazonn, impressed in the lower third of tlieproz)na, wiih 

 some short and low longitudinal c-uiniilre between the trans- 

 verse sulei wiiich are scarcely developed but still perceptible. 

 Elytra extending a little beyond the middle of the nieta- 

 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 prol)ably olivaceous in 

 life ; hind tibiaa pale brown (redilish in life?). 



Length of body li nini. ; pronotiim 3 mm. ; elytra 1"5 mm. ; 

 hind femur b'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 Conophijma^ 

 which it resembles so closely at first sight, because it has no 

 outer apical spine of tlie hind tibire, and belongs therefore to 

 another division- The absence of the prosternal spine seems 

 even to indicate that it is a member of either Acridinje 

 ( = Truxalina3) or Locustinse ( = (E(iipodinfe), but I am more 

 inclined to include it in Catantopince 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 S|)ecimen 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 iiigh altitudes in Central 

 Asia that their Orthopterous fauna is wholly unexplored, and 

 collecting of small, wingless, larvre-like grasshoppers is 

 especially desirable, as they are usually strictly localized, and 

 their extensive study may throw some light on the origin and 

 history of the Palsoarctic fauna.

Through the kindness of Dr. G. A. K. Marshall, Director 

 of the Imperial Bureau of Entomology, I have been able 

 to examine a collection of Fsyllidie from Fiji. Three un- 

 described species appear to be present, and descriptions ot 

 tuem are given herewith.
