Antenna of fl. morio. wanting. Epistoma short, the mouth x 45. aperture large, oblong, reaching up towards the antennae and looking downwards and slightly forwards. There is a well developed oral cone, on the front side of which lies the weakly chitinised clypeus stretching from the epistoma towards the labrum; it is chiefly repre- sented by two chitinous lists; on the posterior side of the oral cone lie the stipites of the maxillse. Proboscis about half as long as the head is high; labrum pointed triangular, nearly as long as labium; the maxillae have a thin, pointed lacinia, about as long as labrum; the maxillary palpi are one-jointed, long, nearly thread-Kke, beset with hairs; hypopharynx thin, long-pointed, somewhat longer than labrum; by judging the length of the mouth parts in relation to the length of the labium it is to be remarked that labrum and maxillae are inserted somewhat basally on the cone because there is a relatively long connecting membrane between the place of insertion of these parts and the insertion of the labium at the end of the cone. The labium has the basal part somewhat longer than the labella, these latter are relatively short and broad, and form a disciform
