and fossil, and from the allied families Elateridae and Eucneinidae ; indeed we cannot 
recall, at this moment, a single genus throughout the whole Coleopterous order in which 
the ordinary punctate-striate sculpture — cousisting of distinct punctures arranged in 
regular series one behind another— is combined with small irregularly disposed 
derations. Its form and structure clearly indicate that it belongs to the Buprestidse, 
and there is little doubt, wo thinlf, of its aiiiuity to that typo of the recent genus 
Stiffmodera (e.g., S. ffradosa, Cher., S. Boei, Hope, &c.), which prerails in Western and 
South Australia. The type of which we speakis represented in New South Wales by one or 
two species, and it is to one of these, S. sanyuinosn, Hope, that the fossil wing appears 
to be most nearly allied. The peculiar punctuation appears to indicate that this Insect 
belongs to a very ancient type, and an examination of the specimen suggests the 
possibility that the ordinary rugose form of sculpture, accompanied by deep pits, now 
so preralent amongst the Buprestid®, may, so far as the Australian species are con- 
cerned, have been derived from this older type.” 
We are indebted to the researches of Mr! .1. II. Simmonds for this very interesting 
fossil. Other Insect remains wore found by him at Ipswich, with one exception the 
remains of Coleop)tera. Two well preserved elytra are certainly referable to the 
Ehynchophora, and one is evidently related to the genus GlocMnorrliiims, or its 
immediate allies. Two other fossils, exhibiting the thorax and elytra, are probably 
representatives of the family Hydrophildsc, both of them having the w'ing-cases 
punctate-striate, &c. A fifth specimen appears to be the head and pro-thoracic segment 
of a Coleopterous larva, possibly of one of the Lampyridse, but in the absence of further 
material, it is not judicious to venture a decided opinion. The only other specimen 
which has, so far, been found, appears to be the impression of the abdomen of one of 
the large Hemiptera.

Unio ipsviciensts, sp. nov., PI. 42, figs. 2 and 3. 
8p. Char. Transversely elongated, narrow, wmdge-like, sub-acute posteriorly. 
Dorsal or cardinal margin short, much less than the length of the shell ; ventral margin 
generally rounded, but straight towards the centre. Anterior end short and rounded ; 
posterior end produced and obtusely pointed Umbones small, quite anterior, and 
much eroded. No true posterior slope, but the flanks insensibly graduating into the 
posterior end. Surface with concentric roughened corrugations. 
Ohs. This species is so generally like many other species of Unio that it is 
difficult to point out its distinctive characters. It is a very much smaller species than 
the following one, and it is quite distinct from anything yet described from Australian 
Mesozoic rocks.
