FOSSIL DRA.GON-FLY IN WARWICKSHIRE. 301 



next the skin ; the hairs are most of them narrowly annu- 

 lated towards the apex with rich brown, or yellow-brown ; 

 the longer hairs are black ; on the under parts of the body, 

 the hairs (which, like those of the upper parts, are of a deep 

 slate-grey at the base), are slightly tipped with brownish- 

 white, or ash-colour ; the feet are covered with dark brown 

 hairs above (not yellow as in Phase. Jlavipes) ; the tail is 

 also dark brown, and on the upper side inclining to black ; 

 the hairs on this part are all short and adpressed. 



There are other differences between the present species 

 and that with which we are comparing it, which may help to 

 distinguish them, I allude to the colouring of the head : in 

 Phase. Jlavipes, the upper lip, lower part of the cheeks, chin, 

 and throat, are white, and there is, moreover, a white spot 

 beneath the eye, whereas, in Phase. Swainsonii, no white is 

 visible, indeed the head is almost of an uniform colour with 

 the body, the hairs on the sides and upper parts are black, 

 slightly grizzled with yellowish, and on the chin and throat 

 they are grey, tinted with brownish, especially on the chin. 



The specimen from which this description is drawn up, is 

 apparently a^^nale, and furnishes the following dimensions ; 

 length from nose to root of tail, 5" 2'" ; tail about 3" 5"' ; 

 head, about 1" 2"' ; tarsus to end of claws, 10 lines : it is 

 from Van Dieman's Land.

Art. VIIT. — On the occurrence of a Fossil Dragon-fly in the Lias 

 of Warwickshire. By H. E. Strickland, Esq., F.G.S., &c. 



The accompanying drawing (fig. 11), represents a very perfect 

 wing of a Libelluline insect, lately found in the lias of 

 Warwickshire. It is the property of Mr. J. Gibbs of Eves- 

 ham, who has kindly lent it to me for examination and de- 

 scription. It exliibits a very distinct impression on the sur- 

 face of a slab of blue lias limestone, the wing being of a 

 pale brown colour, and the nervures a darker tint of the 

 same. The opaque spot which exists at the anterior margin 

 of the wing in most of the Lihellulidce, is here distinctly 

 marked, being of a much darker brown than any other part 

 of the wing. 



This specimen appears to be the left anterior wing of the 

 insect. On comparing it with recent species of Lihellulidce, 

 it exhibits a close resemblance to them in the general ar-
