172 Mr. C. J. Gahan’s notes on the 
13. Phoracantha senio, Newm. 
The Entomologist, vol. i., No. i. (Nov., 1840), p. 4. 
Coptocercus sexmaculatus, Hope, Proc. Zool. Soc., 1840, 
p- 51; Trans. Zool. Soc., vol. iii., 2 (1848), p. 195. 
? Phoracantha gracilis, Perroud, Ann. Soc. Linn. Lyon, 
1855, ii., p. 369. 
A single example of this species was taken by Walker 
at Adelaide River, in North Australia. The species 
occurs also in South Australia (Davis), New South Wales 
(Kirk), Victoria, Queensland, and (if Iam right in re- 
ferring to it the P. gracilis of Perroud) in Tasmania. It 
is quite distinct from Coptocercus biqguttatus, Donov., as a 
variety of which it is placed in the Catalogue of Gemm. 
and Harold. 
The sheets containing Hope’s description of C. sex- 
maculatus were not published until near the end of 
January, 1841,* so that Newman’s name takes priority. 
14. Phoracantha synonyma, Newm. 
Ann. & Mag. Nat. Hist., vol. v., p. 19. 
Freemantle, in West Australia (Walker). One example. 
15. EHpithora dorsalis, Macleay.

Mallocera elongata, Casteln., Hist. Nat., ii., p. 424. 
Stenochorus uniguttatus, Hope, Proc. Zool. Soe., 1840, 
p- 49; Trans. Zool. Soc., iii., p. 198, pl. xii., fig. 4. 
S. rhombifer, Hope, l.¢., p. 49. 
Phoracantha imbellis, Newm., The Entomologist, i. 
(1842), p. 352. 
This species was taken by Mr. Walker at Hobart and 
Franklin in Tasmania, and at Port Adelaide in South 
Australia. Some of the smaller examples taken at 
Hobart resemble Newman’s type in having the apical 
spines of the elytra reduced to the merest rudiments. 
* For this information I have to thank Mr. F. Waterhouse, the 
courteous Librarian of the Zoological Society.
