The specimens are very close to X. coii'/uiirti(.t .lord. (18'J5), from New Guinea, 

 and perhaps only subspecitically distinct. However, the fifth segment of the 

 antenna is pilose on the outside in the i S of me.tile.s, while it is naked in the two 

 cf cJ which we have of conjunct us. Further material of conjnnctus may prove that 

 this difference does not hold good. In pattern iiuxiles differs fnjm conjunrtiis 

 esjiecially in two points. The discal line in the basal half of each elytrum is con- 

 nected behind the base with the sutural stripe in conjunctun, while in mesites the 

 line only bears a short branch which does not reach the sutural vitta; further, the 

 lateral apical line ends at the sutural edge in con/nnctiis and at the a|)ical edge in 

 7nesites. In both species the suture is narrowly edged with white posteriorly.
