C. Head short behind the eyes and semicircularly rounded ; eyes large, 
prominent, looking forwards, in consequence of the front being suddenly

*This species seems allied to C. Traili Sharp, Staphyl. Amazon Valley, Trans, 
Lond. Ent. Soc. 1876, 224; these two species show an approach to the genus Ophites. 
+Cryptobium angustum and eylindricum Sharp, op. cit. supra, 220, seem allied 
by the form of the head to this remarkable species.
