nuUo .' 2. Nesogaster, Verb. 



Genus 1. Nesogastrella, VerhoefF. 

 1902. Zool. Anzeig. no. 665, p. 192. 



I only know this genus from VerlioefF's description. It 

 appears to differ from JSesogaster in the purely rudimentary 

 elytra, which gajje along the suture and expose a triangular 

 scutellum ; the pronotum does not extend so far over the 

 elytra. The pygidium, in the ? at least, is prominent, with 

 triangular points on each side, with two blunt processes. 



It is known only from a single female from Borneo, with 

 which scanty material Dr. Verlioeff did not hesitate not only 

 to describe a new species, but even to found a new genus ! 



Genus 2. Nesogastee *, Verhoeff".

 latius ; elytra postiee truncata ; carina externa acuta instructa ;

Body brilliantly shining, smooth, hairless : antennae with 

 12 segments ; first stout and clubbed ; third long, somewhat 

 clubbed at the apex ; fourth about half as long as third,
