220 Mr. G. C. Champion on the Heteromerous Coleojptera 
becomes wider and deeper before and behind the middle, and large 
and deep basal fovese. Elytra five times the length, and in their 
widest part fully twice the width, of the pro thorax, gradually 
widening for two-thirds of their length and then somewhat 
abruptly narrowing to the apex ; finely and shallowly punctate- 
striate, the punctures closely placed ; the interstices almost flat 
throughout, each with a single very irregular row of widely 
separated fine punctures ; each elytron deeply obliquely depressed 
on the disc below the base. Length 9|^, breadth 3| mm. .( $ ). 
Hah. Tasmania — Franklin^ Huon River. 
One specimen. This insect has more the facies of some 
of the winged species of Helopidse than of a Cistelid. 
Nypsius foveatuSj n. sp. (Plate VI.^ fig. 1, $ .) 
Elongate-obovate, rather narrow, somewhat flattened above, 
shining ; the head, pro thorax, and scutellum, greenish-seneous ; 
the elytra aeneous or asneo-cupreous ; the antennae, femora, and 
under surface in great part piceous, the tibia and tarsi pitchy-red ; 
above sparsely clothed with rather long, decumbent fuscous hairs. 
Head somewhat closely, finely punctate, behind the epistoma 
deeply transversely depressed ; the eyes moderately large, rather 
deeply emarginate, separated by a space about equalling the width 
of one of the eyes as seen from above ; the antennae rather stout, 
extending to about the basal third of the elytra, joints 5-10 long 
and subcylindrical, shorter than 4, 11 shorter than 10, ovate. 
Prothorax transverse, moderately convex ; the sides subparallel 
from about the middle to the base, rounded in front, the hind 
angles rectangular ; the surface thickly, somewhat coarsely punc- 
tate, sulcate down the middle, the groove terminating in a deep 
triangular excavation behind and also becoming deeper in front, 
and with a deep fovea on either side of the disc about the middle 
and very deep basal foveae. Elytra about four and one-half times 
the length, and in the widest part nearly twice the width, of the 
prothorax, obvate, widest at one-third from the apex ; finely and 
shallowly punctate-striate, the punctures closely placed ; the inter- 
stices almost flat, somewhat thickly punctured ; each elytron 
deeply obliquely depressed on the disc below the base. Legs 
simple. Length 7, breadth 2^ mm. 
Hah. Tasmania — Launceston. 
Two male examples. This species somewhat resembles 
a Ghromomsea, but it differs from that genus in the short 
bifid mandibles, short thorax, etc. The thorax has five 
deep foveaB, a character not possessed by any other 
Cistehd known to me.
