I have examined the types of C. catenulata and C. 11l-maculata, and they only 
differ in colour and size. The species isa very variable one, as noticed by Boheman, 
and the elytra are sometimes entirely black. C. omissa was based upon abraded 
specimens of this dark form. C. catenulata may chiefly be known by its moderately 
convex shape (¢ subrotundate, 9 ovate) and pubescent surface, the elytra and the 
sides of the prothorax rather coarsely punctured. Specimens occur with the spots 
small, sometimes with only three on each elytron; those from Western Mexico are 
much larger than the others. We figure a male of one of Boheman’s types of 
C. catenulata (fig. 5), from Playa Vicente, a female of his C. 11-maculata (from the 
Stockholm Museum) (fig. 6), and a female of the variety a from Capetillo (fig. 7). 
13. Chelymorpha juvenca. (Tab. VII. fig. 8, 2.)

Apparently peculiar to the eastern and southern parts of Mexico. Six varieties of 
this variable species are described by Boheman. C. juvenca, especially in the male 
sex, has very much the facies of an Hpilachna, of the family Coccinellide ; it may be 
known by its very pubescent upper surface and convex shape—subrotundate in the 
male, ovate in the female.
