tures and traversed by straight and somewhat radiating veins, which appear Uke 



portions of the hind wing of some species of Butterfly, entirely denuded of scales." 



The name is given to it in a note to the explanation of 



the plates, p. 395. Concerning the second he says:' 



''PL XYin, figs. 27 and 30, appear to be portions of 



the hind wings of some species of Butterfly; still they 



have very much of a vegetable aspect. The surface is 



covered with minute punctures, which may be the cells 



for the insertion of the quills of the coloured scales, 



which are all removed, supposing the specimens to be Lepidopterous." The name 



we have quoted is given only to fig. 27, in a foot note on p. 396. 



I have not been able to find, even with Mr. Brodie's help, the first specimen 

 referred to; but an examination of the original of the latter 

 (see fig. 3) proved that, while it is unquestionably an insect, 

 it cannot be refeiTed to the Lepidoptera; the punctures re- 

 ferred to are both too large and much too irregularly dis- 

 posed to have been the points of insertion of the scales ; they 

 are probably the marks of the insertion of hairs, such as are 

 not uncommonly seen irregularly scattered over the wings of 

 insects belonging to the other suborders. As the figure of 

 the first species closely resembles in this particular the one I 

 have seen, I am forced to the conclusion that neither of these wings are lepidop- 

 terous. Plainly, the only reason why a new generic name was appended to these 

 forms was that their remains were too fragmentary to afford the slightest guess as 

 to what modern genus they might be referred. The fossils came from the English 

 Purbecks.
