PHYTOPHAGA FROM SUMATRA 401 



The penis in tliis species is short and rolmst, strongly curved, 

 ratlier strongly widened at the npox, which is obliquely pointed, 

 t!ie upper cavity is confined to the apical portion only. Tliis 

 small species is closely allied to N. par villa, Jac. from Burmah, 

 ])ut differs in the close punctuation at the sides of the thorax, 

 which part in lY. parvula is very finely and sparingly punctured, 

 the sides of the thorax in the latter s})ecies also are nearly 

 straight and tlie legs are entirely fulvous ; there is no apprecial)le 

 difference ])etween the two sexes in N. fulvitarsis, as far as the 

 punctuation is concerned.

Head with a few fine punctures, tlie clypeus not separated 

 from the face , antennae extending to the Ijase of the elytra ,

 portion rather dellexed, the surface finely and not very closely 

 punctured, the punctures stronger at the sides, basal margin

Of this species, which I at first took to be the female sex of 

 iV. fulvitarsis, tlie male is unknown to me; that the species is
