INSECTA — COLEOPTERA.

from Port Essington. It has already been remarked in last year’s 
report, that the genus Oncinotus of the reporter (ibid. p. 219, founded 
upon Pr. arcuatus, F.) falls under Toooeutes, Newm. 
Blanchard (I’lnstit. p. 23) has made known a beetle from Tangiers, 
under the name of Prionus Favieri, which is very injurious to the 
palm trees. It may, however, be synonymous with Pr. forjicatus, F. 
Newman has described two new species from Manilla, Macrotoma 
cegrotum, and absurdum (Entomol. p. 247). 
There are two new American species of Prionidce, Callipogon 
Lemoinei, Beiche (Guer. Mag. d. Zpol. Ins. pi. 98), from New Granada, 
distinguished from the C. barbatus by a broad longitudinal band of 
white felt on each elytron, interrupted anteriorly ; and Derobrachus 
Levoiturieri, Buquet (Ann. d. 1. Soc. Ent. d. Fr. xi. p. 203, pi. 9, f. 1), 
from Columbia. 
The new genera of the group Cerambycidce are: — 
Euchroa, Guerin (Deless. Souv. d’un Voy. d. ITnd. ii. p. 56, t. 14, f. 
1), allied to Pachyteria, but certainly not distinguishable from Nirmus, 
Newman, as also the species E. dimidiata, Guer., from Pulu Penang, 
is the same with N. tricolor, Newm. 
Sclethrus, Newm. (Entomol. p. 247), founded upon the Ibidion 
amcenum, Guer., is very different from Ibidion, and resembles a 
Tricondyla. 
Ceresium, Newm. (ibid. p. 322), allied to Obrium, with a narrow 
head elongated anteriorly ; includes three new species from the Philip- 
pine Islands, Obr. immite and oethiops (p. 247), and C. raripilum 
(p. 322). Newman remarks, that the New Holland Call, intortum and 
vile, perhaps belong also to this genus (ibid. p. 223). 
Omotes and Sophron, Newm. (ibid. p. 353, 354), are two new genera 
from New Holland, apparently allied to Callidium, which at present I 
do not know, and cannot discover the essential characteristics from the 
description. 
Mecy nopus of the reporter (Arch. 1842, i. p. 222), belonging to the 
Necydalidce ; elytra as in Stenopterus ; antennas and legs long, especi- 
ally the hind ones; thighs only slightly thickened. M. cothurnatus 
from Van Diemen’s Land. 
Blanchard has again attracted discussion to the Purpuricenus Loreyi, 
Duponch. (Ann. d. 1. Soc. Ent. d. Fr. xi. p. 49). He takes the view of 
Buquet, that the Eburia stands near it, and the E. dimidiata, Chevr., 
nearest, but thinks that both these, in some “ plus” and “ moins,” vary 
from Eburia, and either form a peculiar genus Heterops, or Ceraspho- 
rus, Coccoderus, and Chlorida, must be united with Eburia. 
Redtenbacher has described, as a new Austrian species (Col. Austr, 
p. 24), Callidium scabricolle, Meg., but it is the Call, muricatum, 
Dalm., Gyll.
