 upper wing of one of the Cercopidce ; f is 

 part of the wing-cover of a small Blattideous 

 insect ; and % is part of the wing of a Grass- 

 hopper. 

 PI. XV. Fig. 15. The wing of a small Dipterous insect, apparently 

 allied to Simulium. 

 Figs. 16 & 17. Portions of the wings of Neuropterous 



insects, apparently allied to Corydalis. 

 Fig. 18. The lower wing of a species of the Cicadellince. 

 Figs. 19, 20, 23, 26. Apparently portions of wing-covers 



of various species of Blattidce. 

 Fig. 2 1 . Wing of a small Dipterous insect, allied to Chi- 



ronomus or Cecidomyia. 

 Figs. 22 & 24. Portions of wings of Neuropterous insects 



of doubtful family. 

 Fig. 25, A remarkable spotted wing-cover, apparently of 

 some curious Cimicideous insect. 

 Among other fragments of wings, there is also one, 4f lines long, 

 with a few slight longitudinal veins, one of them next the costa being 

 forked : this may perhaps be a portion of the under wing of a small 

 Nepideous insect. 



VII. Fossil Insects from the Dorchester Quarries §. 

 PL XVI. fig. 3. PI. XVIII. figs. 9 & 14. 



Twelve specimens of fossil insects from the Eidgway Quarries 

 near Dorchester, from the bed No. 106 of the Rev. O. Fisher's Sec- 

 tion II, have been forwarded to me by the Rev. Mr. Brodie ; and, being 

 from a distinct bed, it has been thought advisable that they should 

 be noticed separately. 



PI. XVIII. Fig. 9 represents a small insect, destitute of legs, an- 

 tennae, or wings, and which may possibly be 

 the immature state of a Naucoris, or an allied 

 Nepideous insect. The centre of the abdo- 

 men is longitudinally impressed ; and there is 

 a slight depression on either side, parallel with 

 the lateral margin. 

 Fig. 14 may possibly be an insect closely allied to 

 fig. 9 ; it is, however, far less clearly defined, 

 especially in the anterior half of the body. 

 There is another insect siinilar in size to the two preceding, but 

 so slightly indicated that it cannot be described. 



PI. XVI. Fig. 3 represents a portion of one of the slabs, in which 

 it will be seen that a great mass of elytra, of 

 different sizes and forms, have been deposited ; 

 and it is to be observed, that in the original 

 the large dark-coloured elytron has ten, very
