This is a large robust species somewhat resembling C. porcellantis 

 in the character of the keels of the third segment which similarly 

 extend forward over those of the second, but which are rather less 

 expanded. In C. porcellanus the keel of the fourth somite on each 

 side is distally acute with the anterior margin convex and the pos- 

 terior slightly concave, in the present species this keel is distally 

 conspicuously rounded and is bent caudad, showing also a slight 

 notch on the caudal side a little proximad of the tip. The present 

 species lacks the notches on the caudal side of the keels in the pos- 

 terior region of the body, the caudal margins, on the contrary, being 

 straight or the last few bent moderately caudad; although the last 

 two keels show a very small and obscure notch close to the caudal 

 angle. 



Yellowish. Obscure darker marks on the sides and a darker mid- 

 dorsal line showing more distinctly in the caudal region. 



Maximum length near 13 mm.; width, 4.8 mm.
