collected in Australia and Tasmania. 381 
mediate coxal cavities open externally, the trochantin prominent ; 
intercoxal process of the abdomen subtriangular ; elytral epipleure 
entire, broad, equal in width from opposite the metathoracic epimera 
to near the apex, widened towards the base ; legs rather short ; 
anterior tibiz flattened and subtriangularly dilated, with rather 
long spurs, the four hinder tibiz with very short spurs; tarsi 
simple, sparsely clothed with long hairs beneath ; posterior tarsi 
with the basal joint short, joints 1—3 united very little longer than 
the apical one; body elongate, parallel, winged. 
This genus is proposed for a Tasmanian insect allied 
to Toxicwm (and Anthracias), from which it chiefly 
differs in having the head unarmed, the antennez 
gradually widened to the apex (their three or four outer 
joimts not forming a club nor densely punctured and 
pubescent), and the epipleurse broad and entire. Epi- 
towicum, I". Bates, is also an allied genus. ‘The head is 
not swollen on either side near the eyes as in the females 
of Toxicum, nor cornute. The antennal joints are shining 
and similarly sculptured throughout. The sex of the two 
specimens received has not been ascertained. 
Paratoxicum iridescens, n. sp. (Plate VIIL., figs. 8, 8a—c.) 
Elongate, narrow, parallel ; the head, oral organs, antenne, and 
legs ferruginous, the prothorax and elytra dull black, the prothorax 
in one specimen indeterminately ferruginous towards the sides and 
apex, the entire upper surface iridescent. Head densely, very 
minutely punctate, the epistoma a little smoother; prothorax about 
one-third broader than long, rather convex, strongly bisinuate at 
the base and feebly so at the apex, the sides parallel from about the 
middle to the base and rounded in front, the hind angles acutely 
rectangular, the anterior angles rather sharp, the base very finely 
margined and obsoletely foveate on either side, the entire surface 
densely, minutely punctate ; elytra a little flattened on the disc, 
with regular rows of fine punctures, the interstices flat, smooth ; 
beneath shining, obscure castaneous, closely and finely punctured 
along the middle, the sides of the metasternum (but not the 
episterna) with coarser punctures, the ventral segments 1—3 more 
sparsely punctured towards the sides, the flanks of the prothorax 
finely strigose. Length 52, breadth 2 mm. 
Hab. Tasmania—New Norfolk. 
‘Two specimens, found under bark of Hucalyptus.
