 sects from New Holland. By Thomas Marsham, Esq. Tr. L. S.

In the variety of curious insects which I have received from 

 New South Wales, there seems to be a number of new and di- 

 stinct genera. Of these I have selected, as the subject of the 

 following monograph, a genus which does not appear to me to 

 have been noticed by any author. Even Mr. Donovan, in his 

 last elegant and valuable work of the Natural History of the In- 

 sects of New Holland, &c. has suffered it to escape his notice. 

 On the first glance the insects of this genus might, be taken for 

 Chrysomelce, but on closer examination they will be found to 

 differ from that genus in the shape of the body, and the last 

 joint of the palpi ; the antennae also are more filiform, and 

 the exterior margin of the elytra at the base is angular, and not 

 rounded as in Chrysomela and Coccinella. The shape of the body 

 and of the exterior palpi gives them a strong resemblance to Coc- 

 cinella, but the antennae totally exclude them from that ^enus. 

 The dilated elytra of some specimens, particularly on the under 

 side, claim an affinity with Cassida, but in that mark only they 

 agree. 



1 have named this genus Notoclea, from vZ>Tcg,dorsum, and nfc&e, 

 Celebris, on account of the remarkable form and convexity of the 

 back ; and I have formed the generic character from the out-
