Lengili, JO mm. 



Described from one specimen in the Indian Museum from 

 Sibsagar. 



Bigot's description of his faveolus is very short, and would 

 apply to the present species, but as he marked /hZ?;/c7»5 himself as 

 a new species 1 presume it to be distinct. 



Some considerations on the possible synonymy of this genus 

 with LepUjxil2ms, liond., and HelionDjia, Dol., have been set forth 

 by me.* Of the three genera, Leptipalims (1850) would take 

 precedence. Apart from the two species described by me, only 

 one other is Vnoww, j(aveolns. Big., from New Guinea.
