A paper giving biologic notes on some New Mexico Coleoptera was published in “Insect Life,”, Vol. V., p.37–40; and a paper treating of the blister-beetles or meloids of New Mexico and Arizona, in “Psyche,” 1894, p. 100–102. The species mentioned in the latter not at all. These three papers, therefore, will serve as a catalogue, or list with notes, of all the Coleoptera observed by the writer in New Mexico and Arizona except a few, the names of which it has been impossible to get from those to whom they were sent for determination.
