378 Mr. G. C. Champion on the Tenebrionide 
One specimen, differing from the type, which is con- 
tained in the National collection, in having the elytral 
pubescence almost entirely black, with the exception of 
two small patches on each elytron. G. howitti, Pasc., 
is probably only a small variety of the same species with 
the pubescence of the prothorax and elytra almost 
entirely reddish-ochreous. 
CaaNTHUS, n. gen. 
Mentum strongly transverse ; last joint of the maxillary palpi 
stout, oval, that of the labial pair slender ; mandibles bifid at the 
tip ; gula feebly grooved behind the suture ; epistoma truncate in 
front ; eyes coarsely granulated, small, entire, projecting laterally 
beyond the antennary orbits, the latter not prominent ; antennze 
not reaching the base of the prothorax, joints 1 and 2 stout, longer 
than broad, 3--9 slender, 3 considerably longer than 4, 4—9 very 
short, 7—9 strongly transverse, 10 and 11 forming a very stout club, 
10 transverse, 11 about as broad as long, obliquely truncate at the 
tip ; prothorax longitudinally convex, strongly compressed towards 
the sides, and with the apex broadly produced in the middle over 
the head* (partly hiding it when viewed from above), the base 
with broad median lobe ; scutellum not visible ; elytra about twice 
as long as the prothorax; prosternum very narrow, declivous; hind 
coxee widely separated, the intercoxal process broad, truncate in 
front ; epipleurze broad at the base, gradually narrowing to the 
apex; ventral sutures deep; legs short, without distinct tibial 
spurs, the tibiz convex on their outer edge ; tarsi simple, clothed 
with silky hairs beneath ; the basal joint of the hind tarsi scarcely 
equalling joints 2 and 3 united, the three together not longer than 
4; body elongate, convex, thickly covered with brownish scales, 
the upper surface with coarse scattered granular elevations, 
This genus is proposed for a minute insect from 
Tasmania. ‘The general shape is suggestive of that of 
the American genus Calymmus, of the Bolitophagides, in 
which group it must be placed. The stout 2-jointed club 
of the antenna, the gibbous, anteriorly produced, com- 
pressed thorax, and the very small, unemarginate eyes 
are its chief characters. 
Caanthus gibbicollis, sp. n. (Plate VIIL, figs. 7, 7a, b.) 
Elongate-oval, narrow, moderately convex, pitchy-black, the head 
ferruginons in front; densely covered with brownish scales, the pro-
