Names
Scientific source:

Isodontia (Isodontia) philadelphica (Lepeletier) (Figs. 18, 44, 69) Sphex philadelphica Lepeletier, 1845, fist. Nat. Insect, Hymen., 3:340. Holotype ♀, Philadelphia, Pa. (TURIN). Sphex macrocephalus Fox, 1890, But. News, 1:137. Holotype ♀, Philadelphia, Pa. (USNM). Sphex (Isodontia) azteca of authors, not Saussure.


Geographic distribution
Distribution—This species occurs from coast to coast in the United States but does not appear to be a common insect (fig. 18). Our records cover most of the area south of the Great Lakes, from New York to eastern Kansas, thence westward to Texas, Arizona, and California, where it is found mainly along the coast north to the Oregon border.

Natural history
Lepeletier’s species has been questionably regarded as being the same as harrisi (Fernald), e.g., mexicana (Saussure), but examination of the type by Bohart has established the identity of this species as that generally known as azteca (Saussure) (Murray, 1951). True I. azteca, however, is a Mexican species. Cameron’s robusta, described from Mexico, probably is synonymous with azteca. Bohart has studied the type of macrocephalus. Biology.—Menke observed several females nesting in a log in Santa Barbara Co., California.
