It resembles the larva of Xylophagus; the body is cylindrical, of white colour, consisting of twelve segments in all; the head is conical, brown, chitinised, shorter than the following segment, it has on the venlral side> at the base, a soft wart; second segment has on the dorsal surface five chitinised longitudinal bands; the thoracic segments liave some chitinised spots. The last segment is somewhat thickened, with a flattened part on the dorsal surface at the apex, and with two tomentose, longitudinal grooves at the base; at the apex it has two spines; tbe abdominal segments have, on the ventral surface, indistinct, transverse swellings (Kriechschwielen). The larva is amphipneustic I have had only a couple of diied specimens foi' examination, and I therefore chiefly must rely upon earher deseriptions; with regard to the palpi Schiner says: ,undeutlich gegliederf, van d. Wulp says ,tweeledig" and Becher (Denkschr. Kais. Akad. d. Wissensch. Wien, Math. nat. Classe, XLV, 1882, 141, Tab. II, Fig. 13.) says: „ungegliedert". it appeared to me that the palpi in the male are two-jointed, in the female unjointed or indistinctly jointed. 6*
