102 MB. P. P. PASOOE ON THE LONGICOENIA OE AUSTRALIA. 



Dark brown, covered above with numerous, slightly dispersed, white hairs, 



one, or sometimes two or three, issuing from a puncture in the derm ; 



body beneath with more closely set hairs nearly concealing the derm ; 



elytra apiculate at the suture ; antennae reddish brown, covered, except 



the first two joints, with a very delicate pubescence ; legs brown, with a 



greyish pile, the tips of the tibiae and tarsi reddish. Length 12 lines. 



A much finer species than O. infecta, more cylindrical, the 



prothorax more rounded at the sides and without spots, and the 



tarsi more dilated, if this be not, as in some other cases, a sexual 



character. I owe my specimen to the kindness of Mr. Odewahn. 



Paphoea. 

 Caput porrectum, ovatum; tuberibus antenniferis brevibus, remotis. 

 Oculi reniformes. Antennce breves, scapo quam articuli tertii et quarti 

 longiore, caeteris paulo longioribus. Mandibulce, palpi &c. brevius- 

 cula. Prothorax ovatus, basi apiceque truncatus, capite paulo latior. 

 Elytra breviuscula, lateribus parallela, apicibus rotundatis. Pedes 

 mediocres ; femora vix incrassata ; tibice quam tai'si longiores. Pro- 

 et mesosterna declivia, hoc hand elongatum. Abdominis segmenta 

 sensim breviora. 

 The type of this genus is my CeresiiMii ? modestv/ni ( Journ. Ent. 

 ii. p. 237). The genus, however, is nearer Bebius {op. cit. p. 369) ; 

 but it has no muzzle, and is altogether a much shorter form, with 

 longer legs. It agrees with it in having the scape longer than 

 either the third or fourth joints — a peculiarity which at present 

 distinguishes these genera from all others of the subfamily be- 

 longing to the Australian fauna. 



PORITHEA. 



{ cJ ) Caput antice breve, transversum. Oculi magni, reniformes. An- 

 tennce corpore multo longiores, scapo clavato, articulo tertio longiore, 

 quarto breviore, quinto et sequentibus longioribus. Palpi securi- 

 formes. Prothorax basi constrictus. Elytra parallela, apice rotun- 

 data. Pedes longiores ; femora valida, valde clavata, postica elytro- 

 rum extremitatem superantia ; tibice subelongatse ; tarsi antici dilatati. 

 Prosternum simplex. Mesosternum declive. ( 5 ) Antenncs et pedes 

 breviores ; femora minora ; tarsi antici baud dilati. 

 There are three or four unpublished Malayan genera that will 

 come between this genus and Ceresimn. The chief characters, 

 however, that will differentiate it from cognate forms lie in the 

 contracted base of the prothorax, the stout clavate (not fusiform) 

 femora, especially of the male (in which sex the posterior pair ex- 

 tend beyond the end of the body), and the short transverse face. 

 The type {CalUdium intortum, Newm.) is in Major Parry's col-
