180 Mr. C. J. Gahan’s notes on the 
vatis; articulo tertio antennarum quam quarto vix longiori et 
quam primo vel quinto breviori. Long. 12 mm. 
Hab. Tasmanta: Hobart (Walker). 
Head black, with the cheeks fulvous; the front closely but very 
feebly punctulate; prothorax black and opaque, distinctly but 
rather bluntly tubercled on the middle of each side, and with four 
very feeble and almost obsolete tubercles above. Elytra dark 
brown, with a distinct bluish, submetallic tint; crossed by a narrow 
yellowish band at a short distance in front of the apex ; closely 
and rather strongly punctured from the base up to the posterior 
border of the yellow band, the small space between the latter and 
the apex being almost impunctate. Body underneath dark brown, 
legs somewhat darker.

The Meropachys tristis of Hope (Proc. Zool. Soc. 1840, 
p. 58), which is unknown to me, will probably be found 
to be a variety of 7’. undatum, Newm., as was suggested 
by Lacordaire. It certainly is not identical with the 
Saperda tristis of Fabr. (Syst. Ent., p. 186, and Syst. 
Ent., iv., App., p. 453), as would appear from the Cata- 
logue of Gemminger and Harold. The latter species is 
from New Zealand, and has been referred by Broun to 
Lacordaire’s subgenus Ambeodontus. Cerambyx pullus, 
Newm. (The Zoologist, 1851, App., p. exxvili), is, I be- 
lieve, identical with it. 
The Necydalis tristis, Fabr. (Mant. Ins., 1., p. 170), 
which is quoted under Phlyctenodes in the same Cata- 
logue, is quite foreign to the group, and seems to have 
been accidentally substituted for the Saperda tristis just 
referred to. Nothing is left of the type-specimen but a
