The galea bears ashort row of slender setae (k) on its free dorsal margin; the surfaceis armed with rather sparse, long hairs (e). Adopting the terms of other authors, it may be said the lacinia ispilose on its dorsal margin and spinose on its posterior and that thegalea is spinose. Palpi.—The palpi (P) are three-jointed.
