Observations .— Described from a single $ sent by Mr. 
Marshall. It is very near C. cinereus, mihi, but is smaller, and 
differs in not having any lateral white abdominal spots, the 
absence of the white apical spot and the dark venter. It is also 
like C. nigrochaetae, but the ungues of the £ again separate it.
