Seatius rubrilineus. 
Pterosticta rubrilinea, Buckt. Mon. Membrae. p. 230, pl. li. fig. 4 (1903). 
Pterosticta xantha, Buckt. J. ¢. p. 231, pl. li. figs. 7 a, 6 (1903). 
Hab, Adelaide. 
In his deseription of P. xantha Buckton writes :—* Pro- 
notum with two subacute short suprahumeral processes, 
which are only slightly visible by the front aspect.” This 
is shown in his fig. 7 a, but is incorrect, without the specimen 
is turned upside down and then a little tilted backwards. 
The figures 4 and 7 appear very different on pl. li., but are 
the same species, the types of each being now before me. 
Seaxtius spretus. 
Pterosticta spreta, Buckt. Mon. Membrac. p. 2380, pl. li. fig. 5a (1908), 
Sextius longinotum, Kirk. Rep. Haw. Plant. Assoc. 1906, p. 377. 
Hab. Adelaide, Queensland. 
In Buckton’s type, now before me, the posterior pronotal 
process extends slightly beyond the apex of the tegmina— 
the distinctive specific character described by Kirkaldy, but 
not mentioned by Buckton. This is, however, not a constant 
character, for in some specimens the posterior process only 
reaches the tegminal! apex. 
Sextius virescens. 
Centrotus virescens, Fairm. Ann. Soc. Ent. Fr. (2) iv. p. 515 (1846). 
Var. Sextius assimilis, Kirk. Rep. Haw. Plant. Assoc, 1906, p. 376. 
Hab. “ New South Wales, Sydney.” 
Sextius depressus. 
Seatius depressus, Goding, Proc, Linn, Soc, N.S. W. xxvii. p. 12 (1903). 
Kirkaldy (Rep. Haw. Plant. Assoc. 1906, p. 376) 
expresses his doubt that this species is distinct from 
S. virescens, Fairm., and states that it ‘is distinguished by 
the absence of a cross-vein near the base of the tegmina,” 
but that he had not seen the species. Its character, how- 
ever, as given by Goding—“ lateral horns directed outward, 
depressed towards apex, never turned upward,’—is one 
which distinctly marks a series of specimens in the 
British Museum received from Sydney, Queensland, and 
elsewhere.
