REPORT ON ZOOLOGY, MDCCCXLIl : 
C. margaritacea, has three cast skins upon the fork, but no excrement. 
The larvae of C. murrcea, equestris, viridis, and tigrina, have also been 
observed. The larva of a Bengal Cassida is figured. 
Newman has enriched the genus Paropsis (Entomol. p. 414) with ten 
species, which have been mostly taken at Port Philip, on Eucalypti. 
He has given only short diagnoses, so that most of the species cannot be 
determined with certainty. Two of them are Fabrician species, viz. : — 
P. circumdata, N., is Chrys. rujipes, F. ; and P. fallaoc, N., is Chr. 
morio, F. The reporter has described twelve new species of the same 
genus, from Van Diemen’s Land (Arch. 1842, i. p. 226-30). 
Matzek has given an arrangement of the Silesian Chrysomelidce (Ar- 
beit. der. Schles. Ges. fiir Vaterl. Kultur. 1842, i.), but which only refers 
to Timarcha and Chrysomela, in the sense of Dejean. The former con- 
tains three, the latter nineteen species : Timarcha splendens, Kohler, 
according to the short description, must be Chrys. rufa, Meg., Duft. ; 
Chr. atra is certainly not that of Dahl, which is a native of Sicily, but 
a peculiar and different species, allied to the Chr. hemisphcmrica. 
Of the four species described by the reporter from Van Diemen’s Land 
(Arch. 1842, i. 230), two, Chr. constricta and pacijica, belong to a 
peculiar New Holland form, which agrees with Helodes in the pointed 
terminal joint of the palpi, and differs by the claws being dentated at the 
base. The two others, Ch. luteicornis and orphana, belong to Phcedon. 
Colaspis jugularis, C. ( odontionopa ) viridula, and proxima, of the 
reporter (ibid. p. 232), are from the same place. Odontionopa, Chevr., 
is distinguished from the true Colaspis, by two small teeth projecting 
at the anterior margin of the clypeus (ibid. p. 119). 
Saunders has laid before the Entomological Society of London, his 
researches on the New Holland Cryptocephali, accompanied by short 
remarks, but not sufficient from which to form a judgment, at least in 
regard to the newly characterized genera, since no notice is taken of some 
most important points, such as the form of the posterior margin of the 
prothorax, the scutellum, the insertion of the head, and proportion of the 
tarsal joints. Aporocera is allied to Clythra (Proc. E. S. p. 53) ; antennse 
two-thirds of the length of the body, thorax gibbous in front, and as 
broad as the elytra : A. hicolor, and apicalis, from New South Wales ; A. 
chalyhea (ibid. p. 57) from Port Essington. Mitocera (p. 54) ; antennae 
one-third as long again as the body, which is sub-elongate and flattened, 
thorax sub-quadrate : M. viridipennis, from Swan River. Dicenopsis ; 
antennae not half the length of the body, the third to fifth joints long, the 
remainder short, forming a kind of lengthened club : D. hcematodes, from 
Van Diemen’s Land. Ochropsis (p. 56) ; antennae as long as the body, 
joints gradually increasing in size from the sixth, not different from the 
following, except in its pale colour : 0. vermicularis, australis, erosa, 
melanocephala. Idiocephala (Ann. Nat. Hist. xi. p. 317, formerly in
