Fairmaire has described some species as to be attributed to Laius, from Madagascar, Nossi Be. 1 have not seen them, but I suspect it will be found that there are such radical differences as to preclude such an association; and he does not mention enlarged joints. Laius, it may be observed, was founded upon a female example from Australia, and ought strictly to be suppressed for Westwood's name Megadeuterus, which at least expresses the fact that the second joint of the antennae is enlarged in the male sex. That he included other insects in his genus is no reason for suppressing the name, but only for confining it to the type, and to such as can be associated with it. H edonistes l ^e tu s , sp. n.

Femina, fronte plana, antennis simplicibus. JIab. Willowmore, Cape Colony (Brauns). Head and thorax black, thickly and the latter rather coarsely punctured; the antennae have four joints at the base reel, the rest black, the apical joint is elongate, the intermediate joints in the male are longer than wide, in the female about as long as wide, not serrate but rather triangular. The thorax is shining, not wider than the head, and much narrower than the elytra at the base, somewhat cordate, with the margins a little reflexed. The elytra are blue-black, with a fascia which is interrupted at the suture, but very broad on the margin, of a fine blood-red, and their apex is rather broadly margined with the same colour; the basal side of the fascia is produced along the margin so as to surround the shoulder; their surface is uniformly, coarsely, and in places confluently punctured, honeycombed. The legs are black. Eight examples, consisting equally of each sex, were sent me by Dr. H. Brauns, by whom they were obtained at Willowmore in Cape Colony.
