This species was first sent to me by Mr. T. Iredale, 

 with the information that it was un-named. Subsequently, 

 Dr. T. Har^'ey Johnston collectted it in the same locality. 

 It is much like C. ihomnfti Crosse from New Caledonia, 

 but is smaller, duller in colour and more delicately 

 sculj'tured.
