In the system this would come at no great distance from the genus Serica, the compound lamellated joints are, I believe, the first noticed amongst Phyllophagous Coleoptera. Biphyllocera kirbyana, sp. n. Illustration 19 Insects 2 Figure 1 a and b.) Piceo-brunnea, subtus piloso-fulvescens, thoracis margine flavescente, dorso, hirtello; elytris 9 (saltem) lineis longitudinalibus impressis, interstitiis transverse substriolatis quasi squamulatis. Shining, more especially on the head and clypeus, the crown of the head very smooth, the space between the eyes with impressed punctures, the clypeus slightly notched in front; antennae pale-ferruginous; thorax with short rust-coloured hairs, and the lateral margin slightly reflexed and paler than the dorsal part, which is covered with short striolae, giving a squamulate appearance to it; when narrowly examined, just above the rather large and bluntish scutellum, there are some distinct scattered punctures; thorax beneath covered with fulvous hairs. Habitat King George's Sound, Captain George Grey. There are two more or less injured specimens of this species in the collection of the British Museum. In the same collection, from the same locality, are two specimens of what I regarded as the females of the B. kirbyana; they are larger and of a pale brown; one of these is figured in the accompanying wood-cut figure 2. In the lamellae of the antennae of the two specimens there is considerable difference, so that probably there may be a second species of Biphyllocera. I have given it the name of B. fabriciana.

Habitat King George's Sound, Capt George Grey. Donovan's B. cancellata is surely a distinct species, the serrated margins of the elytra and other characters would separate it. I have not seen the work of the Reverend F. Hope, referred to by Messrs. Gory and Laporte, so that I am not aware whether the specific name roei or dejeaniana had the priority in publication.
