MEMOIRS OF THE QUEENSLAND MUSEUM. 
irregularly concave on upper surface and convex on lower, apical joint one half 
longer than subapical. Prothorax moderately transverse, sides strongly rounded, 
with two transverse basal elevations ; with crowded and small punctures on sides, 
inconspicuous in middle. Elytra feebly dilated to beyond the middle ; with crowded 
and small but fairly sharp punctures, becoming subgranulate on the postmedian 
spots. Front femora with a deep impression at apical third, second joint of front 
tarsi with a narrow, black rim. Length, 2 mm. 
Queensland : Bathurst Head (H. M. Hale and N. B. Tindale). Type (unique), 
in South Australian Museum. 
At first glance apparently belonging to L. melanoderes , but head with a pale 
V in front, head and prothorax with much sparser punctures, and basal joint of 
antennae armed in front. The pubescence is also sparser, and the black hairs are 
longer and more numerous. The black parts of the elytra are the basal fourth and 
a large round postmedian spot on each, touching the side but not the suture. 
Laius maculiventris n. sp. 
<?• Flavous, some parts reddish flavous, head (except for a large pale apical 
spot), scutellum, meta sternum, and a transverse spot on each side of most of the 
abdominal segments black, apex of hind femora and apical joints of antennae 
infuscated ; elytra with four large purple spots. With long, straggling, black 
pubescence. 
Head gently convex, with distinct but irregularly distributed punctures. 
Basal joint of antennae stout, curved, dilated to apex and unarmed, third decidedly 
transverse, somewhat lopsided, irregularly concave on upper surface, convex on 
lower. Prothorax moderately transverse, sides strongly rounded, base widely 
depressed ; with dense punctures on sides, sparse elsewhere. Elytra with sides 
feebly dilated beyond the basal fourth ; with crowded and fairly coarse punctures, 
hut absent from parts of the purple spots. Front femora with a deep median 
impression, second joint of front tarsi with a curved black rim. Length, 2*75 mm. 
Western Australia : Geraldton (J. Clark). Type (unique), in South Australian 
Museum. 
The elytral markings are much as on L. eyrensis, but the head is pale in front, 
and the true third joint of antennas is very different. L. cams has basal joint of 
antennae armed and with a black line, hind legs black, &c. L. pallidus lias head 
entirely pale and third joint of antennae of very different shape. L. sinus is a narrow or 
species, with true third joint of very different shape. L. tetrastictus has true third 
joint longer than wide, instead of transverse, &c. The large elytral spots are basal 
and postmedian, the basal spots are rounded posteriorly, and touch the sides but 
not the suture, the postmedian spots are briefly elliptic, somewhat obliquely placed, 
and touch the sides for a short distance, but not the suture ; the terminal joints 
of antennae are deeply infuscated, but the infuscation decreases till near the dilated 
joints it almost vanishes. 
Laius longus n. sp. 
(?• Black, in parts with a purplish gloss, other parts flavous and almost white. 
Finely pubescent, and with not very long, scattered setae. 
Head with dense punctures and opaque, except for a shining, submedian space. 
Basal joint of antennae large and dilated to apex, third wide, irregularly concave
