The larva of a supposed Vesicant, found attached to Antliia cavernosa^ 
is described and figured in detail by Gerst;icker, in V. d. Decken's Reisen, 
iii.pt. 2,fpp. 211-217, pi. xi. figs. \.-\.d. It probably belongs to an un- 
known genus, and its afiinities with the larvae of Sitaris, Meloe, and 
Lytta are discussed.

this group. In addition to the sub-genera Lydoceras and Ceroctis (both 
treated as new, but established by the author in L'Ab. vii. 1870 [c/. Zool. 
Rec. vii. p. 302], and the latter of which now comprises 9 known and 5 
new species), a new sub-genus, Mimestlies, is established, pp. 548 & 566, in 
which the thorax is transverse-quadrate, with no constriction, the elytra 
are flattened on the back and truncate at apex, with a projecting sutural 
angle, and the 3 apical joints of the antennae coalesce, as in Conjna. M.
