below the apex. The two veins bordering (L both appear to be 

 branches of the radius. Media wavy, giving off a short weak con- 

 nection to the radius to form the distal side of rf, . Cubitus with two 

 branches ; the upper one simple, slightly waved, the lower one broken 

 at abont two-fifths of its length, at a point from which a perpen- 

 dicular vein branches off to the posterior border. Rest of wing lost. 



TYPE : Dunstania pukhra, sp. nov. 



OBS. : I have dedicated this, the most perfect and beautiful 

 of the Ipswich fossil insects, to Mr. B. Dunstan, Chief Government 

 Geologist of Queensland, to whose untiring energy and keenness 

 and ceaseless search we owe the preservation of this and the other 

 fossils described in this paper. 



The genus Dunstania may be placed as the sole representative 

 of a new family Dunstam'idae, characterised by the presence of the 

 two cells as shown, and the weak closure of d^ distally. 



DUNSTANIA PULCHRA, sp. nov. 

 Plate 3, fig. 6. 



This almost perfect specimen of a left hindwing is one of the 

 most striking and beautiful fossil insect wings so far discovered. 

 The border of the wing, together with all the veins, is of a pale colour^ 

 On both sides of each vein, and also internally to the wing border, 

 there runs a very distinct brownish band, giving the wing a very 

 striking and characteristic appearance. These brown bands are 

 interrupted, or rather reduced to a lighter tint, across two transverse 

 areas, one just distal to d l , the other between the apex of d. 2 and the 

 external border of the wing. It is possible that this may be simply 

 due to the condition of preservation, or an indication of an original 

 banded colour pattern, which probably existed originalh r also on 

 the scales. 



The external wing-border, or termen, shows signs of a delicate 

 transverse ribbing. This extends also somewhat indistinctly round 

 the apex on to the costa. 



I have to thank Dr. A. J. Turner, F.E.S., of Sherwood, near 

 Brisbane, for the suggestion that this fossil represents a hindwing in 

 spite of the absence of frenulum or jugum.* Neither of these struc- 

 tures need be present in the hindwing of a moth ; for instance, in 

 the recent family Lasiocampidse their place is taken by an enlargement 

 of the costal area. Dunstania may well have resembled a Lasio- 

 campid both in flight and appearance. 



* An observation which has been fully justified by the discovery, since it was made, of 

 ! IK narrower and more elongated forewing of this Fame species.
