has been abraded ; but I know of no insect to which fig. 7, if belong- 

 ing to an Annulose animal, can satisfactorily be referred. 



Of naked-winged insects there is a considerable collection of interest- 

 ing fragments, amongst which those belonging to the Lihellulidce are 

 pre-eminent, as usual, for their size. PI. XV. fig. 4 represents a 

 portion (near the extremity) of one of the wings of a Libellula of 

 very large size. Fig. .5 is one of the wings of a Dragon-fly with very 

 small meshes, and with the characteristic triangle occupying a higher 

 position than in the typical LibellulcB. PI. XVII. fig. 21 is a por- 

 tion of a wing, drawn of the natural size, which, from its general 

 character, is evidently Libellulideous ; but I know no species with 

 such an arrangement of veins ; and, compared with the ordinary 

 types of the family, this fossil insect must have been quite gigantic 

 in size. 



PI. XVII. Fig. 12 represents one of the wings of a Neuropterous 

 insect, allied to Sialis or Panorpa ; and fig. 1 6, 

 one allied to Raphidia. 

 Fig. 19 appears to be one of the narrow elongate teg- 

 mina of a Grasshopper; and figs. 10 and 13, 

 tegmina of Blattidce. 

 Fig. 1 1 seems to be a portion of one of the upper wings 



of a Homopterous insect. 

 Figs. 14 and 15 are a wing and wing-cover of a small 

 Cimicideous insect. 

 PI. XV. Fig. 2 appears to be a portion of a wing of a Tipulideous 

 species. 

 PL XVII. Fig. 17 represents a number of fragments of delicate tegu- 

 ment covered with minute punctures and 

 traversed by straight and somewhat radiating 

 veins, which appear like portions of the hind- 

 wing of some species of Butterfly, entirely 

 denuded of scales. A fragment of larger size 

 will be noticed amongst the Rev. Mr. Brodie's 

 Lower Pur beck insects. 



X. Fossil Insects from the Lower Purbecks, Durdlestone 

 Bay, Dorset *. PI. XIV. figs. 1-8. 



A small collection of insect-remains, 22 in number, collected by 

 W. R. Brodie, Esq., of Swanage, Dorset, has been communicated to 

 me through his cousin the Rev. P. B. Brodie. A few of the more 

 interesting of these are represented in the upper part of PI. XIV. 

 As in the other collections, the greater portion consist of single 

 elytra. 



PI. XIV. figs. 1, 2, 3, are three of the best-marked specimens, 

 the others being of small size. The first of them appears to belong 

 to one of the Eluterida: ; the second is Ilelopideous ; and the third 

 is Curculionideous. 



PI. XIV. fig. 4 appears to me to belong doubtfully to an insect :
