Colour of pronotum from ochraceous brown to black never with dark vittae along dorsum (Figs 38, 56, 65, 76, 88); sexual dimorphism of various type but never anterior tibiae in males with elongate, obtuse thorn apically followed by small tubercle in the middle on inner margin (Figs 39, 57, 66, 79, 89).......................................................2. - Colour of pronotum ochraceous with two dark vittae along middle (Fig. 29); anterior tibiae of male with elongate, obtuse thorn apically followed by small tubercle in the middle on inner margin (Fig. 30)........................ C. bivittata sp. nov. 2. Colour of pronotum and elytra from ochraceous to mostly dark brown, if almost black then elytral costae at least in anterior part paler coloured than dark background (Figs 38, 56, 65, 88); sexual dimorphism manifested mostly in structure of fore and mid legs, interantennal process in males at most as long as in females distinctly shorter than antennomere I (Figs 37, 44, 54, 55, 63, 64, 86, 87)...........................................................................................3. - Colour of pronotum and elytra uniformly black ( Fig. 76 ); sexual dimorphism strongly manifested in structure of head, interantennal process in males twice longer ( Fig. 74 ), in females as long as antennomere I ( Fig. 75 ) …….. C. sarasini ( Heller, 1916 ) 3. Area between third costa and elytral margin behind humeral callus with numerous additional irregular punctures among regular rows; fore and mid femora in males not swollen, apex of fore tibiae without long spine on inner margin.................4. - Area between third costa and elytral margin below humeral callus with two regular rows or at most with 1-3 additional irregular punctures; fore and mid femora in male strongly swollen, apex of fore tibiae with long spine on inner margin (Figs 39, 40, 48, 49)......................................................................... C. freycinetiae (Gressitt, 1960) 4. Interocular plate elongate, distance from anterior margin of eye to anterior corner of interocular plate as long as length of globular part of antennomere I; interantennal process in both sexes short, extending to ⅓ length of antennomere I (Figs 86, 87); expanded apex of prosternum deeply impressed with short grooves and granulation, appears irregular (Fig. 85); elytral intervals behind middle with numerous small and dense additional punctures, rows disappearing among secondary punctures and sculpture apically (Figs 82, 83), area between third costa and outer margin mostly with irregular punctures; midtibiae in males only slightly widened preapically, without expanded plate on inner margin (Fig. 91)...................... C. spinosa sp. nov. - Interocular plate short, distance from anterior margin of eye to anterior corner of interocular plate as long as half length of globular part of antennomere I; interantennal process in males extending to ¾, in females to ⅓ length of antennomere I ( Figs 54, 55 , 63, 64 ); expanded apex of prosternum not impressed, with fine punctures, surface smooth, shiny, regular ( Fig. 53 ); elytral intervals behind middle with large additional punctures, rows not disappearing among secondary punctures and sculpture apically, area between third costa and lateral margin partly with regular rows of punctures ( Figs 51 , 61 ); midtibiae in males strongly widened from midlength, forming expanded plate on inner margin ( Figs 59 , 68 )........... C. panieensis sp. nov.
