Tue Hispine collected by the Percy Sladen Trust Expedition consist of two 
interesting species. It is necessary to erect two new genera for them. Nesohispa, 
n.g., resembles Xiphispa Chap., which occurs in Madagascar and in New Guinea. 
Brontispa Sharp, which has also certain affinities with Nesohispa, occurs in Rodriguez 
Island, Mauritius, Luzon, New Guinea, the Aru Islands, and New Pomerania (New 
Britain). Nesohispa seems to be an intermediate form between Xiphispa and 
Brontispa. 
Rhabdotohispa, n.g., has a close resemblance to Celenomenodera Blanch., which 
is distributed in Madagascar and West Africa. In Rhabdotohispa the apical joint 
of the antenna seems to be formed by the fusion of several joints which are distinct 
in Celenomenodera. The sensory pit under the last jomt of the antenna of Rhab- 
dotohispa is a very remarkable character. Both species were taken only in the high 
endemic mountain-forests*. In preparing this paper I have received great assistance 
from Mr Hugh Scott, who has very kindly checked my work and has made the drawings 
of the antenne. 
Nesonispa, n.g. (Figs. 1 and 2). 
Body elongate, parallel-sided, not very strongly depressed. Head longer than 
broad, produced between the antenneze into a blunt process; near the middle of the 
head there commences a longitudinal groove which widens out at the base of the 
process and continues along this to its apex. Hyes viewed dorsally not so prominent 
as in Brontispa Sharp, inferior, large, convex. Antenne (Fig. 2) 11-jointed, scarcely 
reaching the base of the thorax; joint 1 longest, almost as long as 2 and 3 together, 
almost cylindrical, constricted at the apex (the constricted portion somewhat resembling 
a very short separate joint); joints 2—6 subequal in length, constricted at the base, 
* The locality-lists would seem to indicate that these Hispine are in some way connected with certain of 
the endemic palms.—H. Scorv.
