margin of the same colour. Legs brown, with the base of the 

 thighs and the middle of the tibiae yellow. 



Length, 4 lines. 



This may probably be identical with Casnonia Clarensii of 

 Castelnau, a species from the Clarence River, but Castlenau 

 makes no mention of the third joint of the antennaa being much 

 longer than the following ones, a peculiarity which should properly 

 exclude it from the genus altogether. 



11. Casnonia globulicollis, n.sp. 



Of less elongate form than C. angusticollis, the head bluish- 

 black, nitid, smooth and convex, rounded behind abruptly into a 

 very narrow neck, and with the frontal impressions deep but 

 short. The whole body, head included, is clothed rather thickly 

 with long soft erect hair. The thorax is red, nitid, of globular 

 form, much narrowed in front and behind, about as wide as the 

 head at the eyes, and scarcely longer than wide. Elytra broadly 

 ovate, nitid, rather thinly punctate in rows, only about twice 

 the length of the thorax ; in colour purplish-black, with a broad 

 fascia from behind the shoulders to the suture, where it is pro- 

 longed backward, and a spot near the apex, of a deep red colour. 

 The base of the thighs and the greater part of the tibiae are pale 

 yellow, the rest of the legs brown. The third joint of the 

 antennae is not longer than the following ones. 



Length, 3 lines. 



This species might be taken for an Ophennia, but the fourth 

 joint of the tarsi is entire. 



12. EuDALiA Wateriiousei, Casteln. 



Mast. Cat. Sp. 62. 



Castelnau described this species from a specimen from Arnheim's 

 Land, given to him by Mr. Waterhouse of South Australia. Tlie 

 genus, which is widely distributed throughout Australia, is classed 

 by Castelnau with the Sub-family Ctenodactylides, because the 

 elytra are not truncated ; it is notwithstanding, however, not lar 

 removed from the Odacanthides.
