Palpicornia. 
Count Ferrari (Wien. ent. Mon. Bd. viii. pp. 473-478) describes the known 
species of the genus Calohius (Well.), of which he recognizes five, namely C. 
(Ochth.') siibinteger (Mills.), C. (O.) notahilis (Ros.), C. heerii (Woll.), C. 
(O.) quadricollis (Muls.), which he regards as distinct from C. notahilis and 
C. (O.) lejolisii (Muls.). C. siibinteger and C. lejolisii form a regular transi- 
tion toAvards Ochthehiiis) and hence the author is inclined to adopt the 
opinion of Be Marsuel, according to which Calohius is only a section of 
Ochthehius. 
Be Mathan publishes a description of the larvfe of Ochthehius lejolisii 
(Muls. & Rey) with notes and figures by Fauvel. Ann. Soc. Ent. Fr. 4® s^r.
