behind the middle, the sides rounded anteriorly and slightly con- 
verging behind, the base strongly bisinuate, the hind angles rect- 
angular ; the disc deeply sulcate down the middle, the groove not 
extending to the apex ; the basal foveas long and deep. Elytra 
about four times the length of, and slightly narrower than, the 
prothorax, gradually narrowing from the base to the middle and 
thence rapidly narrowed to the apex, the apices attenuate and 
slightly dehiscent ; the disc flattened along the suture and with 
indications of three faint costse, the sutural stria deep ; the humeri 
transversely strigose ; the apical third of the suture and the outer 
limb at the apex finely denticulate and setose. Legs slender and very 
elongate ; the intermediate and hind tibiae with numerous trans- 
verse ridges on their outer edge, their spurs very unequal in length. 
Anterior tarsi slightly dilated in the male. Length 5|-8 
breadth l-l^ mm. 
Hah. Tasmania — Franklin_, and New Norfolk. 
Four specimens, varying greatly in size and colour. 
It agrees perfectly in its structural characters with the 
type of the genus, G. fasciatum, Redt. " This insect was 
found only among chips and on freshly-cut surfaces of 
woodj where some large Eucalyptus trees had been 
^ ringed ' ; it does not appear to possess the power of 
leaping like an Orchesittj but runs with greater speed 
than any beetle I have ever met with, and, being very 
fragile, is most difl&cult to secure in good condition

Orchesia austrina, n. sp. 
Moderately elongate, convex, pitchy-brown or fuscous, clothed 
with fine sericeous fulvous pubescence ; the antennae rufo-testa- 
ceous, the six outer joints darker, the legs ferruginous ; the entire 
surface densely, very minutely punctate. Maxillary palpi sub- 
serrate, the apical joint moderately large and securiform. Antennae 
slender, moderately long, the apical five joints thickened, 8-10 
about as broad as long, 11 ovate. Eyes widely separated. Pro- 
thorax semicircular, strongly transverse, the basal fovese shallow. 
Elytra forming a continuous outline with the prothorax, moderately 
long, rapidly narrowing from about the basal third. Prosternal 
process triangular. Length 3|, breadth 1^ mm.
