Soldier. — Head pale yellowish brown, the nose rather more brown 

 than rest of the body, antennae brown, pronotum brownish in front, 

 dorsum of abdomen rather dark brown, venter and legs pale. Head 

 pyriform, vertex not as much rounded as usual, below the middle it is 

 faintly constricted, nose long and slender, all parts finely hairy, the 

 hairs mostly very short, but a few longer ones; antennae slender, 

 third joint but little longer than the second; legs and body finely 

 haired. Length 3.2 mm.; head 1.4 mm. 



By slight constriction of the head it is related to C. toussainti and 

 C. flaveolus, but the nose is much longer and more slender than in 

 either; the head is much paler than in C. toussainti and darker than 

 in C. flaveolus; the head is more finely haired than in C. toussainti, 

 and the antennae much longer than in C. flaveolus; the constriction 

 of the head is less than in either of these species.
