Longicornia of Australia and Tasmania. 191 
52. Ancita marginicollis, Boisd. 
Acanthocinus marginicollis, Boisd., Voy. del’Astrolabe, 
Ent., p. 490, pl. 9, fig. 12. 
Examples of this species were taken by Mr. Walker at 
Hobart and Launceston in Tasmania. The species ap- 
pears to be rather common in Australia, especially in 
the southern portion of the continent. 
58. Ancita sparsa, Pase. 
Hebesecis sparsa, Pasc., Journ. Linn. Soe., vol. ii., 
p ’ : I 
p. 854; Journ. Linn. Soc., vol. ix., p. 81. 
Taken by Mr. Walker at Hobart and Launceston in 
Tasmania, and at Fremantle and Cape Leeuwin in West 
Australia. The Tasmanian examples agree with some 
from South Australia, and differ from those from West 
Australia (which in other respects they almost exactly 
resemble) by having an interrupted pubescent white line 
along the middle of the pronotum. But as portions of 
the pubescence are very liable to be rubbed away, little 
importance need be attached to this difference.

= Atyporis; Pasc.,l.¢., p. 67. 
With the exception of Aegomomus, Pasc., which is 
considered a synonym of Micracantha, all the above are 
placed as distinct genera in the Catalogue of Gemminger 
and Harold. Pascoe distinguishes Atyporis from Aeqo- 
momus by characters that seem to me to be of merely 
specific importance. Two described species only are 
mentioned by Blanchard as entering his genus Pro- 
soplus. One of these—P. sinuatofasciatus, Blanch.—is 
closely allied to, if not one of, the species which Pascoe 
included in Atyporis; while the other—Acanthocinus 
hollandicus, Boisd.—appears to be very nearly allied to, 
or even identical with, the following species.
