ubrotundato ; prozona sat tumida, sutura mediana distincta, 
utrinque impressa; elytra brevia, truncata, quadrata, carina 
laterali acuta, per totam longitudinem elytri percurrenti ; al

This genus is well characterised by the form of the 
elytra which are almost square, with a sharp and very 
distinct carina along the edge, running throughout the 
length of the elytra; the wings are wanting in the only 
known species, which in general characters otherwise 
resembles Chelisoches. 
The type, and only known species, is Chelisoches punctu- 
latus, Burr, Ann. Mag. N. H. (6), xx, p. 315 (1897), 
from the Southern Celebes. 
Genus 2.—CHELISOCHELLA, Verhoef.

Chelisochella, Verhoeff, 1902, Zool. Anzeig., No. 665, 
pol96. 
This genus, very inaptly named by Verhoeff, for it con- 
tains the giant of the group, is characterised by the form 
of the elytra, which are broadened in the middle, and 
furnished with a lateral keel throughout their length. 
Verhoeff includes in it the species Chelisoches pulchripennis 
and ylaucopterus, Borm., but he was evidently not familiar 
with the species, for they do not possess the essential 
character mentioned by him, that is, the long keel of the 
elytra; in other respects, C. pulehripennis approaches to 
this genus, that is, in colour and in the form of the feet ;
