NotoUster nodicornis, sp. n. 



Oralis, parum dcpressus, niger, nitidus, supra punctulatus, antcnnis 

 pedibusque piceis ; fronte anterius deprcssa, hand striata; pro- 

 noto stria marginali integra ; elytris striis subhuraerali uulla, 

 dorsalibus 1-3 intcgris, 4-5 apicali brevibns, suturali antice 

 evanesceute; propj'gidio pygidioque distincte punctatis ; prostcrno 

 bistriato, lobo punctato ; mesosterno sinuato, stria integra ; tibiis 

 anticis 7-8-spinosis. 



L. 3^ mm. 



Tills small species is very distinct from the others described 

 in being flatter and finely thougli distinctly punctured above. 

 The prostcrnal stride do not meet anteriorly and the fourth 

 dorsal stria has a basal puncture and the fifth an elongate 

 mark, which indicate ap))endages. The mesosternal stria is 

 fine and marginal at the sinuosity only, but it is continued 

 laterally to tlie posterior edge of the metastenmm. 



The trivial name is suggested by a prominence on the upper 

 edge of the scape of the antenna, a character common to all 

 the species of JS'otoh'ster.
