The distributional area of the genus comprises the 

 mountainous districts of many of the Mediterranean countries, 

 namely, Portugal, Spain, Switzerland, northern Italy, the 

 islands of the Grecian Archipelago, and north-eastern Africa, 

 whence it extends eastwards through the Caucasus, Asia 

 Minor, Arabia, Persia, Sind, and Baluchistan to Central Asia. 



The genus is closely connected with Pseudo'is by means 

 of C. cauaisica ojlindricornis.
