ON COLEOPTEEA , MOSTLY FNOM QUEENSLAND. 
355 
about base transversely strigose. Antennae not very long and moderately serrated. 
Pro thorax slightly longer than the greatest width, widely depressed near base ; 
sides with sharply defined punctures, elsewhere sparse and small. Elytra with 
crowded and rather small, but sharply defined punctures. Basal joint of front tarsi 
with an inner black comb. Length, 5 mm. 
Queensland : Kuranda, in February (F. P. Dodd). Type, in South Australian 
Museum. 
The eyes are much smaller than on C. vigilans, which is somewhat similarly 
coloured, and the interocular elevations are different. On the type each elytron is 
suddenly dilated from the basal third, but this is almost certainly due to post-mortem 
shrinkage. 
A specimen from Kuranda, taken by Mr. Dodd in December, agrees so perfectly 
in ail details of colour and sculpture, except of parts of the head, with those of the 
type, that it evidently belongs to the species. On it the curved frontal impression 
of the type is interrupted in the middle by a bottle-shaped extension of the median 
elevation, much as on the head of Helcogaster bacchanal is : between this and each eye 
are two small elevations completely divided, instead of semi-double. Its elytra 
are parallel-sided throughout, and clasp the abdomen in the usual way. 
Carphurus pallidipennis Mack, var. excrementarius n. var. 
A male from the Upper Williams River (New South Wales) evidently belongs 
to this species, as the median apex of the prothorax has the conjoined fovese of the 
species, as previously noted, 5 but each elytron has a small and conspicuous blackish 
granule at the middle of the basal third (the two look just like fly-specks) ; on the 
previously noted specimens they are paler anti just traceable. 
Carphurus marginiventris Fairm. 
The starting point of the longitudinal infuscation on each elytron of this 
species is marked by a small granule that could be easily overlooked on some 
specimens, but is very distinct on others. 
Helcogaster bifoveiceps n. sp. 
<J. Deep shining black, elytra whitish flavous, a rounded space about scutellum 
(occupying about the median third of base) and apical third, black or blackish ; parts 
of front legs and basal half of antennae obscurely reddish. With scattered, black 
hairs. 
Head flattened, with two small round fovese in front. Antennae rather short 
and feebly serrated. Prothorax moderately transverse, sides rounded, almost 
impunetate. Elytra slightly longer than head and prothorax combined, sides feebly 
dilated to near apex ; almost impunetate. Basal joint of front tarsi moderately 
long, with a black inner comb. Length, 3 mm. 
$. Differs in having the frontal fovem smaller, and shallower, the antennae 
slightly shorter, and the elytra and abdomen wider. 
Victoria : Mooroopna, in January (F. E. Wilson). Types, in South Australian 
Museum ; cotypes, in Mr. Wilson’s collection.
