Along the Pacific coast from Humboldt County, California, to Ensenada, Lower California. From an examination of speci- mens, this species, which Miers * says is scarcely to be distin- guished from /. ochotensis, Brandt, is seen to be specifically distinct. It differs from /. ochot- ensis in the proportions of the body, /. rectilineata being more slender—about five times as long as broad—while in I. ochotensis the length is only three and a half times greater than the width; in the relative length of the antennaj to the body and the proportions of the joints in the peduncle of the antennae, the antennae in /. ochotensis reaching only to the posterior margin of the third thoracic segment (in all the specimens examined), the joints of the peduncle being short and stout, while in /. recti- lineata the antennae extend to the posterior margin of the fifth thoracic segment, the joints of the peduncle being long and slender ; in the form ot the anterior margin of the head, * Journ.
