C. Whitei is 5^ lines in length, and 3£ in width ; black, with brownish scales ; 

 rostrum with a longitudinal depression, the base obtusely carinated, the forehead with 

 a slight swelling on either side ; thorax narrow, the sides nearly straight, above very 

 uneven, rugose, the middle longitudinally impressed, and with an irregular transverse 

 depression behind the middle ; elytra above uneven, deeply punctured, the punctures 

 arranged in somewhat irregular rows, the second and tifth (or sixth?) insterstices each 

 with four large obtuse tubercles, and the apex with some smaller tubercles. Hab. 

 Richmond River, New Holland. 



Eurychirus, a new genus of the Molytidce, near Hypera. Rostrum and antennae 

 nearly as in Hypera punctata ; the head rather more exserted ; the thorax without any 

 trace of post-ocular lobes : the legs very long and very stout, the femora much incras- 

 sated in the middle ; the tarsi very large, and unusually broad. 



2?, bituberculatus. Length 4£ lines ; width 2f lines. Form short and broad ; 

 elytra with the humeral angles produced, obtusely angled : black, clothed with green- 

 ish gray, sub-metallic scales ; rostrum pitchy, carinated ; thorax thickly punctured ; 

 elytra punctato-striated, the punctures each enclosing a scale ; each elytron with a 

 large tubercle nearly in the middle, and a smaller one, sub-apical in its position. 

 Hab. New Holland. 



Placoderes, a new genus of the Cyclomides, nearly related to Acantholophus, but 

 differs in having the funiculus of the antennae distinctly seven-jointed, the head and 

 thorax destitute of spines, the latter very broad, much produced at the sides, and 

 nearly angular in the middle, the dorsal surface nearly flat : elytra pedunculated, not 

 touching the prothorax. 



P. variegatus. Length 9 lines ; width 3| lines. Black, clothed with minute, nar- 

 row scales, some brown and some yellowish ; rostrum tricarinated ; thorax thickly 

 granulated, and slightly grooved along the middle ; elytra punctato-striated, the 

 punctures remote, interstices with small glossy granules, variegated with dirty yellow, 

 brown and black. Hab. unknown, probably Australia. 



Ectemnorhinus, a new genus of the Phyllobidce, near Phyllobius ; the general 

 form more elongated and less convex ; rostrum shorter ; the antennae inserted in a 

 cavity near the apex, which cavity has the fore part opening laterally, the hinder part 

 curved inward, and opening on the upper surface of the rostrum : elytra much elon- 

 gated, and each elytron obtusely rounded at the apex: body soft. 



E. viridis. Length 3| lines ; width 1^ line. Elongate, pitchy, clothed with 

 metallic green scales ; legs and antennae ferruginous ; thorax small, sub-cylindrical, 

 but slightly swollen in the middle, and rather obscurely keeled ; elytra delicately 

 punctato-striated. Hab. Kerguelen's Land, in the Southern Ocean. 



Drepanoderes, a new genus, also of the Phyllobidce, remarkable for the thorax 

 being produced on either side into a large sub-recurved pointed process, the apex of 

 the process extending beyond the humeral angle of the elytra. 



D. viridifasciatus (an insect in the collection of the British Museum), is 2f lines 

 long; black; antennae and legs red, clothed with bright green metallic scales; head 

 with a triangular black patch behind ; thorax punctated, with three longitudinal de- 

 nuded bands ; elytra punctato-striated, each with four irregular, short, transverse,
