Var. a. — Tlie pubescent bands of an asliy white instead of 

 a yellow colour. Pronotum of ^ marked anteriorly with a 

 small punctate area on each side of the middle line in addition 

 to the lateral punctate areas. 



Hah. Texas. 



Var. /3. — Pubescent bands ashy white or pale yellow in 

 colour. Pronotum of S marked anteriorly with a median 

 subrotundate punctate area, which is joined by means of a 

 transverse punctate band with each of the lateral punctate 

 areas. 



Hah. Mexico: Villa Lerdo, Durango {Hoge). 



From C. rohinice, Forst., which they greatly resemble in 

 markings, C. cari/ce and its varieties may be distinguished 

 by the thicker, longer, and usually darker-coloured antennae, 

 by the two widely separated yellowish or whitish spots on 

 each of the metathoracic episterna, the limitation of the sexual 

 puncturation of the male pronotum to the anterior part, and 

 in having the intercoxal 'process of the prosternum nearly 

 parallel-sided. 



In C. rohtmcB the antennse are generally reddish brown in 

 colour, somewhat slender, as a rule distinctly shorter (never 

 longer) than the body in the male ; the yellow pubescence 

 forms an almost continuous band on each of the metathoracic 

 episterna, when it is broken up into two spots the interval 

 between the spots is always narrow ; the intercoxal process 

 of the prosternum widens out posteriorly, its sides being 

 curved instead of almost parallel. The sexual puncturation 

 of the pronotum of the male is much more extensive than in 

 C. cart/ce; it covers the greater part of each side, forms 

 an anterior transverse band, and two bands running back- 

 wards on the disk diverging a little behind and dilating each 

 into an oval or rounded spot between the middle and the 

 base ; it is similar in character to that occurring in the 

 North-American species C. decora, Oliv., and the Brazilian 

 C. mellyi, Chevr.
