This is primarily a West Indian and American species, and the 

 identity with it of the forms here referred to is doubtful. Daday 's 

 species may be identical with Kraepelin's C. ncocaledonicus in which 

 case it would have precedence. Ribaut points out various minor 

 differences of his single specimen from the Aru Islands from typical 

 C. impressus.

Color olive, with head more brown. 



Cephalic plate finely punctate; with two sulci diverging forward 

 and extending beyond middle, nearly attaining level of caudal edge of 

 eye group; basal plates distinct. Antennae composed of seventeen 

 articles of which the first five are glabrous and the sixth less densely 

 hairy, Tergites margined from the ninth or tenth caudad; paired 

 sulci distinct from the first to the twentieth; a median keel distinct 

 though low from the third caudad, Aveaker on the second, a very 

 obscure lateral keel also evident on each side of many of the plates. 

 Each prosternal dental plate a little wider than long, with three 

 teeth or the most mesal of these showing a slight tendency to djvide. 

 Prosternal plate with two fine sulci uniting at an angle in front and 

 crossed by a transverse line which gives off branches. Ventral plates 

 from the second to the twentieth with two complete longitudinal sulci. 

 Last ventral plate strongly narrowed caudad; caudal margin very 

 weakly incurved. Legs without tarsal spines. Anal legs enlarged 

 as usual ; femur with a single spine at distomesal angle above and one 

 on mesodorsal edge between the distal one and the middle of length; 

 ventral surface with four spinules in two widely separated rows of 

 two each and mesal surface with three of which one, larger than the
