361 
Prothorax longer than its greatest width, widely depressed near base ; with minute, 
scattered punctures. Elytra moderately long, slightly dilated posteriorly ; with 
minute rugose punctures. Basal joint of front tarsi with a black inner comb. Length, 
4*0-4- 5 mm. 
9. Differs in having the head almost entirely black, the antennae thinner and 
even less serrated, less of the elytra black, and the front tarsi simple. 
Queensland: Mount Glorious, in September (H. Hacker). Types, in 
Queensland Museum. 
The "colours are much as those of II . tuberculifrons, and of the preceding 
species, except that the base of the head is not dark : from the former it also differs 
in being considerably larger ; the latter has larger eyes and the head without foveas 
II. tuber culiceps is similarly coloured, but the tubercle and excavation on the head 
are different. The females "are scarcely to be distinguished from the females of several 
other species. The median elevation on the head of the male is obscured by rather 
numerous black setae, which almost conceal a narrow transverse impression, behind 
it, from some directions, they seem to be compacted into two short transverse rows, 
this being due to an almost concealed transverse impression between them. Close 
to each eye there is a rather large fovea, appearing simple from some directions, 
semi -double from others. 
Helcogaster gagatinus Lea. 
Seven specimens, from the Cairns district, belong to this species, and, apart 
from slight differences of shades of colour of the front legs, agree so closely with the 
typical form that it does not appear desirable to name them as varietal. 
Helcogaster foveiceps Lea. 
Some males from Ringwood (Victoria), in the National Museum, differ from 
typical specimens, with which they were taken, in having the prothorax with a 
narrow blackish basal fascia up to almost entirely black : they have the median 
joints of antennae more deeply infuscated than usual ; one female has one of the 
apical joints pale. Numerous males from Brisbane, Sunny bank, and Mount Coot-tha, 
in the Queensland Museum, have the median joints of antennm more lightly infuscated 
than usual ; on two of them, in fact, the antennae are uniformly pale. Several 
females, taken with them, have some of the apical joints of antennae pale. 
Helcogaster medioapicalis Lea. 
A male from Sydney differs from the type in having the prothorax entirely 
pale, with the medioapical notch smaller. 
Neocarphurus seminiger n. sp. 
c?. Fla vo us and deep, shining black. Very sparsely clothed. 
Head with a large interocular tubercle, on each side of which is a distinct 
fovea, base with rather dense punctures. Antennas long and thin, scarcely serrated. 
Prothorax distinctly longer than wide, convex in front, and much wider there than 
near base, where there is a deep transverse impression, sides finely longitudinally 
strigose, elsewhere with minute punctures. Elytra about as long as head and 
prothorax combined, with a large subtriangular impression on each side at apical
