Obs . — The remarkable character of the ornamentation, or sculpture, of 
this wing will at onee distinguish it from the various genera of the family 
Buprestidae, both recent and fossil, and from the allied families Elateridoe 
and Eucnemidae; indeed, we cannot recall at this moment a single genus 
throughout the whole Coleopterous order in which the ordinary punctate- 
striate sculpture, consisting of distinct punctures arranged in regular series 
one behind another, is combined with small irregularly-disposed elevations. 
Its form and structure clearly indicate that it belongs to the Buprestidae, and 
there is little doubt, we think, of its affinity to that type of the recent genus 
Stigmodera (e.g., S. gratiosa, Chev., S. Roei, Hope, &c.), which prevails in 
West and South Australia. The type of which we speak is represented in 
New South Wales by one or two species, and it is to one of these, the Stigmo- 
dera sanguinosa, Hope, that the fossil wing appears to he most nearly allied. 
The peculiar punctuation seems 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 prevalent amongst the Buprestidge, may, so far as the Australian species 
are concerned, have been derived from this older type. 
Various other Insect remains were found in this Ipswich deposit, but 
none of them are in a sufficiently good state of preservation to admit of 
accurate determination. With one exception they are certainly the remains 
of Coleoptera, and several of them bear a superficial resemblance to the 
remains described by Mr. Charles Moore from Sydney Elat, Of these, two 
well-preserved elytra are certainly referable to the Bhynchophora (PI. II, 
Eigs. I and 5), and one of them, measuring 3 mm. in length, is evidently 
related to Glochinorrhinus, or its immediate allies. It has the whole surface 
of the wing minutely and regularly tuberculate, a strongly-raised suture, and 
a very decided lateral ridge extending from the shoulder to the apex. Tw^o 
other fossils, exhibiting the thorax and elytra, are probably representatives 
of the family Hydrophilidse (PL II, Eigs. 6 and 7 ) ; both of them have the 
wdng-cases punctate-striate, and in one the segmentation of the abdomen is 
clearly shown. A fifth specimen appears to be the head and prothoracic 
segment of a Coleopterous larva (PL II, Eig. 8), possibly of one of tlie 
Lampyridoe, 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 larger 
Hemiptera (PL II, Eigs, 9 and 10).
