Imms, 1913, records a maximum of twenty-nine antennal segments for females of Embia major Imms; while Walker, 1914, records exactly the same number of segments (namely tiventy- nine) as the maximum for females of Grylloblatta campodeiformis, Walk., thus showing an astonishingly close agreement in the num- ber of antennal segments occurring in the two groups of insects. Indeed, there is a greater variation in the number of antennal seg- ments among insects belonging to the same order, or even family, elsewhere in the lower Pterygota, and, coupled with other ana- tomical features no less striking, this clearly points to a remarkably close relationship between the Embiids and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of Canada (1863-1871); Entomological Society of Canada (1951- ); Entomological Society of Ontario.
