REVISION OF THE NYCTOZOILIDES. 145 
N. obesus, Guer. — In Trans. Ent. Soc. London, 1873, p. 348, 
Bates gives a. comparison of N. obesus, Guer., with N. Deyrollei, 
stating the length of the type on the authority of M. E. Deyrolle 
a>s 9 lin. ; bait the author gives 20x11 mm. Two specimens sent 
me by Mr. Illidge, from South Queensland, exactly fit the descrip- 
tion, and correspond to the figure given in Lacordaire (except in 
the exaggerated fovea on the pronotum in that plate), and measure 
18 x lOJ mm. 
N. reticulatus, Bates. — My specimens, compared with type, 
come from various parts of South-west New South Wales (Dubbo, 
Guntawang, &c). I have taken a long series myself at Moorilla, 
near Young™. 
N. irregularis, Blackb. — A specimen, labelled a,s from Cool- 
gardie, has been sent for determination from the National Museum, 
Melbourne (part, of the French collection), and exactly corresponds 
to the author's diagnosis. 
N. Dceuieli, Haag-Rut. — I have a specimen, labelled " Rock- 
hampton," which exactly fits the description. It lias not the slightest 
affinity with the species which Mr. Blackburn describes as 
N. Sloanei, though suggested by that author (Proceedings Linn. 
Soc. N.S.W., 1894, p. 104). Amongst other differences N. Sloanei 
is more than twice the size of N . Deemeli. 
N. crassicornis, Blackb., and N. approximatus, Blackb. — 
Specimens, bearing labels with their names, in Mr. Blackburn's 
handwriting, from the Horn Expedition, have been examined by 
me. Besides the differences noted by the author between these 
.species, N. appro ximatus has the margins of prothorax more 
explanate and horizontal and corrugated, its border less thick and 
raised, the posterior angles much less acute and less (scarcely at 
all) produced than in N. crassicornis. 
STYRUS. 
Dr. Haag-Rutenberg states that S. (Nyctozoilus) el on gat id as, 
Macl., is not identical with S. elonqatulus, Bates, but without o-iyino- 
5 too 
any reason beyond the inference that the types of the insects 
referred to have been compared ; at least, that is the meaning I 
attach to his words " wie die Typen auswiesen." I have cotypes
