This species is extremely variable in size, and the punctuation of the ventral 
segments is also variable to a considerable extent. It may, however, be always 
recognized amongst its allies by the narrow, numerously punctured head, the thorax 
with the base gently rounded and not in the least sinuate, the well-marked acute 
angles of the elytra, the unimpressed or only obscurely impressed prosternum, and 
the sexual characters. The last ventral segment of the female is not truly impressed, 
but has a rather extensive, somewhat triangular, deplanation of the surface in the 
middle. In the large males the sexual supplementary punctures at the sides of the 
ventral plates are distinctly seen, though confined to a quite small space; but in the 
small males only a few of these punctures exist, and may readily be overlooked. 
Herr Hoge procured a large number of examples at Bobo, and these exhibit the great 
variation in size remarked on above; the series does not include, however, any 
specimens quite so large as those he met with at Misantla or Jalapa. Outside 
Mexico the species would appear to be rare, only two females having been procured at 
Mirandilla, and one in each of the other localities, and as these few specimens are 
rather aberrant, and the male is unknown from there, it is just possible they may 
prove to be distinct, but this I think is extremely improbable. These females have, 
however, the ventral segments decidedly more sparingly punctate than usual. 
We have no evidence of the occurrence of 7. chevrolati in our region more to the 
south than Salvador or Guatemala, so that its existence in Brazil, as recorded by 
Reitter 1, is open to considerable doubt.
