236 Mr. G. 0. Champion on the Heteromerous Coleoptera 
Mystes jplanatus, n. sp. (Plate VI., fig. 7.) 
Elongate, parallel, above and beneath (the eyes excepted), the 
antennae, and legs f errugineo-testaceous, the body clothed with a 
very fine sericeous pubescence ; the head and prothorax slightly 
shining, densely, finely punctate ; the elytra opaque, very densely? 
exceedingly minutely punctate, the punctures much finer than those 
on the head and prothorax. Prothorax as wide at the apex as at the 
base ; the sides as viewed from above parallel, rounded in front 
and obliquely converging at the base ; the vertical lateral portion 
rapidly narrowing posteriorly ; the disc broadly and shallowly 
depressed along the middle behind and with shallow basal foveas. 
Elytra about four times the length of the prothorax, parallel for 
three-fourths of their length and then arcuately narrowed to the 
apex, very depressed, and with indications of several faintly-raised 
lines on the disc, the humeri rounded. Beneath densely, very 
minutely punctate, the meso- and metasternum smoother, the pro- 
sternum almost impunctate, the propleurae punctured like the upper 
part of the prothorax. Length 6f , breadth H mm. ( ^ ). 
Hah. Tasmania — Launceston. 
One specimen ; a second in the British Museum-set.

Tellias, n. gen. 
Head short, rather broad, scarcely deflexed, with well-defined 
frontal suture ; eyes moderately large, rounded, prominent, lateral, 
coarsely granulated ; apical joint of the maxillary palpi narrow, 
ovate, obliquely truncate at the apex ; mandibles bifid at the tip ; 
antennae short, extending very little beyond the humeri, slender, 
joints 2 and 3 subequal in length, 4-10 obconic, 8-10 scarcely longer 
than broad, 11 much longer than 10, ovate. Prothorax transversely 
subquadrate, truncate at the base and apex, not wider than the head 
including the eyes, with deep oblique basal foveae. Scutellum small, 
strongly transverse. Elytra much wider than the prothorax, 
widening to beyond the middle, moderately elongate. Anterior 
coxae subcontiguous, separated by a very thin lamina; the cavi- 
ties closely externally, but widely open behind. Middle coxae 
very narrowly separated. Posterior coxae widely separated; the 
intercoxal process broad, triangular. Legs short, slender ; tibial 
spurs very small ; penultimate joint of the tarsi lamellate beneath, 
the basal joint of the hind pair as long as the following joints united.
