on the oth, 6th and 7th coitae, and Avith a small triangular patch of 

 the same hue on the suture, first and second costae, close to the apex ; 

 that pateh forms an apical triangular plaga extending really on both 

 elytra ; in some specimens the apical part of the outer margin is also 

 yellowish ; underside coppery -blue, legs reddish. 



I know of no Chlcenius which this species is closely connected ; it 

 comes in the vicinity of C. fulvicollis, Ch., the facies and size being 

 alike ; the postical sub-triangular patch is very mush like that of 

 C. vitticollis, Boh., but it is far removed from that species in other 

 characters and markings.
