REPORT ON ZOOLOGY, MDCCCXLII : 
The following new genera belong to the New Holland Fauna : — Pen- 
tacosmia, Newm. (Entomol. p. 361) ; a small Lamia^ with the third and 
fourth antennal joints greatly elongated, and the fifth bearing a tuft of 
hair ; one spine on the sides of prothorax, and slightly thickened thighs. 
SympJieletes (ibid. p. 362), corresponding in form to Lam. Solandri, F. 
Zygocera, Dej., was described by the reporter from its external character 
(Arch. 1842, i. p. 224) ; and a new genus, Illmna, characterized for a 
small form of Saperda, with simple claws, distinguished by the palpi, 
the last joint of which is very large and sharp pointed. 
Rhytiphora piperita, tuhercxdata, detrita, Hathlia lacteola, 4:-li- 
neata, lineella, melanocephala, of Hope (Proc. Ent. Soc. p. 49), are 
new species from Port Essington. Acanthoderus inglorius, Penta- 
cosmia scoparia, Rhytiphora mixta, caprina, Symphyletes nodosa, of 
Newman (Entomol. p. 361), are from Port Philip. Lamia pardalis of 
Newman (ibid. p. 414), is from Sydney. Zygocera canosa and Illoena 
exilis of the reporter (1. c. p. 223, 225) are from Van Diemen’s Land. 
I am doubtful concerning the position of the genus Callipyrga, Newm. 
(Entomol. p. 413), with one new species, C. turrita ; it has rather small 
eyes, not emarginated towards the base of the antennae. 
Spalacopsis, Newm. (Entomol. p. 303), is a remarkable new American 
genus. It has the form of Hippopsis, but differs in the eyes, which are 
small and round, and situated on the sides of the head, distant from the 
base of the antennae. In this it agrees with Tetraglenes (vide supra), 
only the eyes on the vertex are here wanting. There are three species, 
Sp. stellio from Brazil, Sp. stolata and sufusa from East Florida. 
There are two Austrian Saperdce, S. (Phytoecia) uncinata and higuL 
tata, Redtenbacher (Col. Aust. p. 25, 26) ; the second is already de- 
scribed in the first volume of the Bull. Mosc. von Zoubkoff, as 8. 
hipunctata. 
8. [Phytoecia) cirteensis, 8. (Oherea) maculicollis and mauritanica, 
Lucas, are three new 8aperdce from North Africa (Ann. des Sc. Nat. 
xviii. p. 187). 
In the group of Lepturidce, Mulsant has described the known Toxotus 
cinctus [Rhagium cinctus, Fab.), as a new species, under the name 
T. dentipes (Ann. des Phys. publ. p. le Soc. d’Agric. de Lyon, v. p. 109, 
t. 11, f. 2 ; Col. de Fr. LameUicorn. Suppl.) 
Hope has noticed Rhagiomorpha unicolor and plagiata as new 
species from Port Essington (Proceed. Ent. Soc. p. 49). 
Pseudocephalus, Newm. (Entomol. p. 353), is a remarkable new genus, 
which I mention here at the conclusion of the Longicornes, as its posi- 
tion seems doubtful, although the author places it in this family after 
Callidium. The eyes are not emarginated ; the antennae somewhat 
more than half the length of body, rather thickened towards the point 
(in the figure they become rather thinner), the first joint elongated ; the
