The Burrowing Bugs of Hawaii, with Description of a New Species (Hemiptera: Cydnidae)

The Hawaiian fauna now contains four species of burrowing bugs, each belonging to a separate genus and each introduced: A wide ranging species of southern Asia and many Pacific islands; a Formosan species; a native of the Greater Antilles and the southern tip of Florida; and one species, apparently undescribed, closely related to certain forms occupying lands around the Indian Ocean. Undoubtedly all arrived on the Hawaiian Islands as unwitting passengers on man's transportation vehicles. The four species may be separated by the key at the end of the text or by careful comparison with the accompanying illustrations (figs. 1-6). On the latter the critical points are the number and kinds of spines occurring sub-marginally on the head; the shape of the cuticular modification associated with the scent gland opening on the metapleuron; and the shape and extent of the evaporative areas (stippled) on the meso- and metapleura
