Attestations from sources in English: 

One wonders whether the construction, tlalli (land) + xiquipilli (a bag or sack), refers to the beetle's appearance: "The back is rounded, ball-like; the neck slender, constricted; the nose has hair, or horns. The jaws are pointed. It has long legs. It is black, like bitumen. And this small insect lives only in the summer; it is not rare." General History of the Things of New Spain, 1963, p. 91.
