The femoral article in particular is strongly compressed and very broad. In fact, the lateral view of the female crab reminds one greatly of the burrowing Orthopteran insect Gryllotalpa with its stout strong first pair of legs modified for burrowing. Heller, in 1862, also called attention to the resemblance in general shape to the cylindrical wood-boring beetles. But Cryptochirus differs from both these

Heller, in 1862, also called attention to the resemblance in general shape to the cylindrical wood-boring beetles. But Cryptochirus differs from both these cases in the fact that no active boring and burrowing is performed and the great development of one pair of appendages in both Cryptochirus and Gryllotalpa is thus due to different 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 Carnegie Institution of Washington.
