the A ustralian Longicornia. 563 



obscufus, Fab., but it is very distinct, especially in its more robust 

 form, shorter prothorax, transverse scutellum, elytra spineil at the 

 apex, and other characters. Phacodes differs very slightly from 

 Hesperophanes ; the chief points appear to be the absence of 

 tubercles on the disc of the prothorax of the latter, and the 

 shortness of the fourth joint of its antennae (a common character 

 among the Callidium forms) ; the more typical species of Phacodes 

 have the third and three or four following joints spined at the 

 apex. 



Genus Callidium. 



1. Callidiu7n ascemoides. 



C. nigrum, subnitidum 5 prothorace subtransverso, disco de- 

 presso sub-bituberoso ; antennis brevibus, articulo tertio 

 duobus sequentibus conjunctis longiore. 



Adelaide. 



Black, slightly nitid, with a few slender erect hairs; head coarsely 

 punctured, a slight, impressed line between the eyes ; antennae 

 rather more than half as long as the body, the third joint rather 

 longer than the fourth and fifth together ; prothorax depressed, 

 broader than long, rounded at the sides, very coarsely punctured, 

 except in the centre, with two tolerably large but very slightly 

 elevated tubers placed transversely, with an impunctate space be- 

 tween them ; scutellum transverse, rounded posteriorly ; elytra 

 oblong, depressed, with nearly parallel sides, and strongly marked 

 with rugose, irregular impressions ; body beneath pale brown, 

 strongly punctured ; legs slightly pitchy ; femora clavate. 



Length 6 lines. 



The dark uniform colour, and the length of the third antenna! 

 joint, will readily distinguish this from any other Australian 

 species. 



2. Callidhim ehuratum. 



C. rufo-ferrugineum, opacum ; prothorace rotundato, basi con- 

 stricto ; elytris nigro-fuscis, rugoso-punctatis, fasciis duabus 

 angulatis albis ; femoribus clavatis, basi gracilibus ; antennis 

 articulo tertio quarto longiore, cseteris sub-aequalibus. 

 Sydney. 



Reddish ferruginous, opaque, with a few white scattered hairs ; 

 head thickly punctured; eyes widely emarginate ; antennae shorter 

 than the body, the third joint longer than the fourth, the succeed- 

 ing nearly of equal length ; prothorax slightly longer than broad, 

 rounded at the sides, contracted at the base, with coarse crowded
