174 Mr. C. J. Gahan’s notes on the 
antennis (?) quam corpore vix longioribus, articulis 30 ad 6um 
apice extus spinosis. Long. 25, lat. 7 mm. 
Hab. Roebuck Bay, North-west Australia (Walker). 
This species has, at first sight, a rather strong resemblance, 
owing to its general colour and pattern of marking, to Phoracantha 
semipunctata, quinaria, &e., but may be distinguished by its 
having the femora strongly clavate below the middle. The disk of 
the prothorax also is less flattened, and bears five smooth, slightly 
raised tubercles, the intervals between which are but sparsely 
punctured; the sides of the prothorax are rather thickly punctured, 
and each bears in the middle a rather short conical tubercle or 
spine. 
This species, notwithstanding its robust form, seems 
to be, on the whole, best placed in Coptocercus. Between 
it and the long slender forms, such as C. biguttatus, 
there is a succession of species, in which there is a 
somewhat gradual elongation and narrowing of the pro- 
thorax, and of the body generally.

Rufo-testaceus, sparsissime setosus; prothorace nitido, vix 
punctato, antice posticeque sulcato-constricto, lateraliter in medio 
leviter tuberculato ; elytris dense fortiterque et seriatim punctatis, 
supra paullo depressis, flavo-testaceis, fascia lata transversa versus 
apicem, suturaque et vitta brevi laterali, plus minusve infuscatis ; 
articulo tertio antennarum sat longe spinoso; (¢@) segmentis 
quatuor primis abdominis foveo tomentoso utrinque obtectis. Long. 
11 mm. 
Hab. Tasmanta: Hobart (Walker), South-east Tas- 
mania (Atkinson). 
Head sparsely punctured. Prothorax nearly twice as long as 
its basal width, with a distinct transverse groove about half-way 
between the middle and the anterior margin, with a less marked 
but very strongly sinuate groove near the base; the disk shiny, 
almost impunctate, with a very narrow and almost obsolete eleva- 
tion along the middle, and with a very feeble, but broader and 
more obtuse, elevation towards each side; sides of the prothorax 
sparingly punctured, each with a feeble median tubercle. Elytra 
strongly, closely, and seriately punctured from the base up to the 
beginning of the posterior dark brown band ; thence to the apex 
more feebly and more sparsely punctured; the disk of each elytron 
slightly depressed along the middle ; apices rounded and unarmed. 
Legs fulvous-testaceous. Antenne longer than the body, setose,
