Dr. Signoret has separated, under the name of P. confusus, the Mexican and North- 
American specimens hitherto considered as representives of P. margo, relying upon 
differences of punctuation, particularly upon that of the costal area of the corium. In 
typical P. margo this area is almost levigate, while in P. confusus it is thickly punc- 
tate; but specimens from the intermediate localities, such as Guatemala, are also 
intermediate in this character, and I therefore prefer to let the species (a variable one) 
remain as before. 
7. Pangeus rugifrons. 
Pangeus rufifrons (p. 7). 
By a misprint this name appeared as “rujfifrons.” Signoret has since seen Prof. 
Uhler’s specimens identified as belonging to this species, and considers them as not 
conspecific. The habitat “ North America,” given on Uhler’s authority, must therefore, 
on these considerations, be withdrawn.
