tibiae. The species differs from the two preceding in its evidently 
narrower elytra (compared with width of prothorax). From i\ r . 
Hardcastlei it differs also in its much wider and less elevated costae, 
the much coarser vermiculation of the intervals, and more coarsely 
punctured thorax ; from N. carbonarius it further differs in its lighter 
colour, with its tendency to red, its complete absence of elytral 
reticulation, the evenly rounded sides of prothorax with very slight 
sinuation, &c. It is evidently much larger and with coarser sculp- 
ture than N. Dcemeli, Haag-Rut,, a species identified by me in an 
insect from Rockhampton. 
NYCTOZOILUS RUFICORNIS n. sp. 
Oblong-ovate, convex, dull-brown above, reddish-brown beneath, 
glabrous, antennae and tarsi chestnut-red. Head — Labrum emar- 
ginate and ciliate, epistoma truncate with rounded angles, its sides 
making an obtuse angle with the prominent and ear-like canthus, 
forehead tumid at base, depressed anteriorly with two transverse 
ridges, one nearly straight limiting the epistoma behind, the other 
cresoent-shaped, extending between the eyes and defining the 
frontal impression,, the whole irregularly and finely rugose, 
antennae scarcely reaching base of prothorax, joint 3 about equal 
in length to 4 and 5 combined, 8-10 rounded, wider than 7, 
eleventh ovate-acuminate. Prothorax 4 x 6.5 mm. (length 
measured in middle), widest at middle, arcuate-emargmate at apex, 
subtruncate at base, anterior angles sub- a cute (nearly rectangular), 
prominent and directed outwards and a little upwards, sides widely 
rounded, distinctly sinuate in front, only slightly so behind, pos- 
terior angles sub-rectangular, not produced or prominent, foliaoeous 
margins wide, corrugated and slightly undulate (a little above the 
horizontal in front, below the horizontal behind the middle), the 
base, sides, and angular portion of apex having a thin, entire, 
nitid border. Disc coarsely and irregularly rugose, with ill- 
defined medial channel, with some close shallow punctures showing 
near the sides. Scutellum widely transverse, with triangular de- 
pression behind it. Elytra oval, wider than prothorax at base 
and about twice as long, shoulders obtusely rounded, showing 
narrow epipleural fold, sides a little widened to the middle, apical 
declivity moderate, each elytron separately rounded at apex,
