REPORT ON ZOOLOGY, MDCCCXLll : 
an aberrant male of Bolbocerus, and certainly B. australasice, Kirby, 
is the female, upon which, also, the genus Bolbocerus is founded. 
The reporter has increased the group of Dynastidce with one new 
genus, Pimelopus, which has, in common with Cheiroplatys, Hope, the 
hind legs strongly thickened, with leaf-like terminal spines, &c., but is 
distinguished by its three- toothed anterior tibiae, also three-toothed man- 
dibles, five-toothed maxillae, and a body more swollen. One species, 
from Van Diemen’s Land, P. porcellus (Arch. 1842, i. p. 159) ; also 
Cheiroplatys moelius of the reporter (ibid. p. 158). 
Waterhouse has made known a Beetle of Valdivia as Oryctomor- 
phus (?) pictus (Entomologist, p. 261), which Guerin has already 
described as 0. variegatus. The author was only acquainted with the 
female, so that his opinions with regard to the definition of the genus 
are not well gTounded, 
In the group of Rutelidce, Guerin has characterized a new genus, 
Barymorpha (Delessert Voyage, ii. p. 40, t. 11, f. 2), which, in most 
points, agrees with Parastasia, but differs in the claws of the hind tarsi 
being equal and simple ; B. bimaculata, the only species, is from the 
island of Penang, on the coast of Malacca. Parastasia has also been 
enriched by the same author with a new species from the same place, 
P. obscura ; and Westwood has added another, P. rufopicta, from Sylhet 
(Proc. Ent. Soc. p. 55). 
Harris (Ins. of Massachussets, p. 23) mentions, that the Pelidnota 
punctata is often found, in great quantity, on the wild and cultivated 
vine, the leaves of which they gnaw, and do much harm to the fruit. 
They fly by day. The larva lives in decayed wood. 
Mulsant has divided the Melolonthidce (Col. Fr. p. 405) into four 
groups, MelolontharicE, Sericarioe, AnomalaricB, and Hopliarice, the 
characters of which are only given in regard to the European ones, 
and taken from the claws alone ; the author distinguishes the Serica^rice 
from the Meldontharioe, by their claws being so cleft at the point, that 
the under tooth is broader and blunter than the upper. I have formerly 
remarked (Arch. 1 Jahrg. i. p. 261), that in this division the labrum is 
concealed, so that the anterior margin of the mentum lies immediately 
upon the clypeus ; there are also some other characters which are found 
united in the European Seriacce, and which extra European genera have, 
individually, in common with them. The Anomalarice are distin- 
guished by simple, and, in general, remarkably unequal hind claws. 
This is always the case ; but it does not distinguish them from the 
Hopliarice, for which the author gives a single hind claw as a charac- 
teristic, as the greater number of the extra European, especially the 
numerous South African forms of this division, have two simple unequal 
claws like the Anomalarice. The want of the terminal spines, on the 
hind legs, should rather characterize the Hopliamioe. The division
