Additional Note.—Since this was written, I have received, through the courtesy of Mr. Hardy, a female paratype of his Boreoides suhidatus. Comparing this specimen with the type of Bor. tasmajuensis, 1 have found that the diflferences in the annulation of third antennal joint and in the position of hind coxae are not constant, being similar in the two species. On the other hand, there are very important differences in the shape of scutelhun, in the lengtji of wing-rudiments, and in the coloration of the back of mesonotum. I find, moreover_, that the legs of tasmaniensis are considerably more thin and.
