The protluiracic stigmatii in this tri1i(! xnw not covered ))y the iullexed portion of the ])ronotum; but, witliout reference to this cliaructer, the insertion of the antennte upon the front will distin- guish the genera from those of all other tribes except the group of Steiur', and these will be readily known by the small anterior coxie. Groups are indicated by the following characters:â Internal lolio of the maxilla; membranous internally, and ciliate ; Eyes not jironiiiient; third joint of maxillary palpi moderately (>longated. :. Eyes prominent; thir .,,iint of maxillary palpi thickened. Internal lolie of tlie maxilla) elongated, entirely corneous, hooked at the tip, and serrate internally. Gviim' Group I.âAleocharae. In this group the interior lobe of the niaxillix; has the internal margin membranous and ciliate; the nnixillary palj)! are moderate ill length, with the second and third joints moderately elongated, the fourth small, subulate, distinct, and in Aleochara with an additional very small fifth joint. The eyes are never very convex. The genera of this group arc very numerous, and frequently catinot be distinguished without the most close examination, or even dissection; it is consequently imjjossible, within the limits of a work like the present, to give such characters as will enable the student to recognize them with certainty.
