of Macleay's insect, and the very detailed description of Bates, 
accurately corresponds to these. Bates himself says, " I have but 
little doubt that the species is the same as that described by 
Macleay." But I do not think that Macleay's type has ever left, its 
original quarters in the Australian Museum, Sydney. Hence with- 
out further evidence I must conclude that Dr. Haag-Rutenbsrg was 
mistaken, and that there was no need for the name S. Batesi which 
he proposed for Bates's insect, and which appears in Junk's new 
catalogue ; and that the following synonymy holds : — 
^ ru j Batesi, Haag. 1 = S. elongatulus, Macleav 
\elongatulus, Bates) (NyctozoilusX 
Having collected a long series of Styrus in Southern Queensland 
and Northern New South Wales, I must express some doubt as to 
the absolute certainty of the above synonymy, since it would be 
possible to make two or three species from these specimens. The 
variations in size and sculpture are considerable, but while any 
lingering doubt remains as to the synonymy referred to I think 
it unwise to add to the mystery by the description of closely allied 
forms. 
Table of Styrus. 
A. Sides of prothorax nearly straight. 
Propleurse coarsely punctate; dim. 17x7 mm. clongatidus, Macl. 
Propleurae less coarsely punctate ; dim. 
12x5 mm. ... ... ... ... ... clathratus, Blackb. 
B. Sides of prothorax much widened ; dim. 16 x 8'3mm. lalior, Carb. 
S. clathratus, Blackb. — I have a specimen, exactly correspond- 
ing to the description, given me some years ago by my friend Mr. 
T. G. Sloane, without any locality label. It is probable that this is 
a cotype, since Mr. Blackburn also obtained his specimen from Mr. 
Sloane. It is readily distinguished by its small size, more cylindric 
form, paler colour, and finer sculpture from S. elongatulus, Macl. 
S. latior, Cart. — Specimens of this were taken by Mr. Sloane 
and myself at Guyra, New South Wales, in December, 1910. 
Amongst other differences the elytral costrc and reticulations are 
much more sharply raised than in S. elongatulus, Macl. 
BYALLIUS. 
A table of the species of this genus has already been published 
(Proc. Linn. Soc. N.S.W. 1909, p, 141).
