Mr. Sloane in a footnote states that Rhytisternus sulcatipes, 
Blackb., is &. levilaterus, Chaud. I cannot look upon this as 
more than a guess, inasmuch as M. Chaudoir never really de- 
scribed levilaterus but only indicated its differences from 
f. liopleura. Of course it may be sulcatipes but inasmuch as 
M. Chaudoir says that in levilatera the fifth elytral stria is 
“‘omnino obliterata,” while in swlcatipes that stria is perfectly 
traceable throughout the length of the elytra; and as moreover 
levilatera is said to be from Queensland while I have seen 
sulcatipes only from Southern Australia, I look upon the identity 
of the two as far from being established. 
Discussing the affinities of Cyclothorax Mr. Sloane expresses a 
doubt whether that genus can be placed in any of the recognised 
tribes of Carabide. I think however it may be placed in the 
tribe for which (Proc. L.S., N.S.W., 1892, p. 85) I proposed the 
name Ambiytelides. 
Mr. Sloane agrees that, as stated by me Tr. Roy. Soc., §.A., 
1894, p. 203, Cyclothorax cinctipennis, Black.—C. (Phorticosomus / 
lateralis, Cast. 
Australian coleopterists owe a debt of gratitude to Mr. Sloane 
for such a memoir as this on which Iam commenting. I sincerely 
hope that he will be able by degrees to treat all the larger genera 
of Australian Carabide as he has now treated Homalosoma and 
Rhytisternus, and that in due course the tribes of Lebtides and 
Harpalides will be dealt with by him after the manner in which 
he has dealt with the Feroniides. 
TRECHUS. 
T. atriceps, Macl. In Proc. L.8., N.S.W., 1892, p. 97, I men- 
tioned having seen the type of this species at Sydney and noted 
that it seemed to be a Thenarotes. Recently Mr. Masters has been 
good enough to send me an example and [I find that my opinion 
was correct. It is very close to my Thenarotes discoidalis var. ? 
minor, but certainly distinct, being much smaller and having the 
basal part of its prothorax differently sculptured. In 7. atriceps 
there is a basal punctulate depression extending almost from the 
central channel to the lateral margin scarcely deepened into a 
fovea in the middle, while in 7. minor the punctulate space is a 
distinct (though not sharply defined) fovea separated from the 
central channel by a considerable unpunctured interval.
