Popis:	Three geographic isolates of the range caterpillar, Hemileuca oliviae Cockerell, from Chihuahua, Mexico, and New Mexico, were compared by electrophoretic analysis of ten enzymatic proteins and measurements of male wings and genitalia. Nei's index of genetic identity for Raton (northeastern New Mexico), Vaughn (central New Mexico), and Chihuahua (Mexico) samples ranged from 0.985 to 0.999, indicating a high degree of similarity among all populations. Mean heterozygosity ranged from 0.029 to 0.156; the Chihuahuan populations were consistently the highest and the Raton population consistently the lowest. Morphological results were variable, Chihuahuan specimens having significantly larger wings but smaller length/width ratio values than the New Mexican specimens. Genitalia measurements averaged consistently larger in the Raton population. We conclude the populations are conspecific.
