The numerous individuals of both sexes from Central and South America referred 
by me to this species differ from the description given by Kraatz (loc. cit.) in being 
larger, the epistoma in the male very deeply emarginate (sometimes with a feeble 
tooth in the middle), the posterior femora in the same sex flattened and swollen, the 
outer half of the upperside of which is concave and finely rugulose within. These 
examples, however, vary considerably in size (19-30 millim.), and in the size of the 
head in the male: fully developed males have the head long, large, and strongly 
exserted ; in other smaller examples of the same sex from the same locality the head 
is scarcely larger or more exserted than in the female, the epistoma less deeply emar- 
ginate, and the posterior femora smoother, though always concave within. I cannot 
but regard these as more than forms of one species. 
Z. ambiguus, Kr., is perhaps allied to this, but the description of that species is too 
short to speak with certainty. 
10. Zophobas kraatzi. 
Form of Z. laticollis, less opaque. The head in the male not larger or more exserted than in the female, the 
epistoma broadly but not very deeply emarginate in the male, closely and rather finely punctured on each 
side before the eyes; prothorax less convex, the sides straighter (less narrowed towards the base); elytra 
sculptured as in that species; the posterior femora in. the male much less swollen, smoother, and not 
concave within. 7
