He remarks that there are two strong mandibles, with four brown teeth, and adds: Two pairs of palpi are also visible—two and tUree-joiiited—apparently those usual in lepidopterous larv:c, but-I have not defined their relations. There is also a poiat (spinneret). I add rough sketches of the mouth parts, as far as I could draw them with the camera fromspecimens mounted in balsam by Dr. Chapman.

The labium and itspalj)i are much as in Gracilaria, but the palpi appear to be three-Jointed, with a terminal bristle(it is iiossible that there are but two Joints). Unlike the larva of Micropte
