PI. XV. Fig. 8. Left-hand figure — possibly the segment of the 

 body of an elongated insect. 

 Fig. 9. Abdomen of a very small broad beetle; — Cocci- 



nellidce 1 

 Fig. 10. Abdomen of a small beetle. 

 Fig. 1 1 . Metasternum and abdomen of a sniall beetle. 

 Fig. 12. Mesonotum and abdomen of a small beetle ; — 



very obscure. 

 Fig. 13. Larger figure — mesosternum of a beetle; pro- 

 bably one of the small Dyticidcs. 

 Right-hand figure — abdomen of a small beetle. 

 In addition to these, there are — the thorax and elytra (in place, but 

 crushed) of a small beetle ; one and a third of a line long ; of a broadly 

 ovate form : — the abdominal portion, 3 lines long, of a beetle, without 

 its elytra, but covered apparently with the wings folded up : — and 

 two small flattened insects, each a line and a half long, which look 

 like little beetles, or CimicidcB, without wings ; the limbs and the 

 elytra are wanting, and the articulations very indistinct. 



A great number of elytra (of which the majority of these fossils 

 consist) are of very small size, not being more than 1|^ or 2 inches 

 in length, varying from the narrow form of an Agrilus to the oval 

 form of a Chrysomela, and with the surface plain, simply striated, 

 punctate-striated, or deeply punctured. 



PI. XV. fig. 8, right-hand figure, and fig. 13, two upper figures, 

 represent several of these small elytra. 



The finest pair of elytra is represented in PI. XV. fig. 7, of the 

 natural size. The base and apex in these elytra are unfortunately 

 wanting, both in the specimen and its cast. The surface is abraded ; 

 it has, however, evidently been finely punctured, and bears several 

 plain narrow longitudinal costse. It may have belonged to a broad 

 species of Prionus or Buprestis, both of them lignivorous beetles. 



Wings. — The wings, although numerous, and presenting many 

 distinct types, are, like the foregoing, unfortunately in general only 

 fragments of single wings, and unaccompanied by any portions of the 

 bodies to which they belonged ; so that we can judge only by ana- 

 logy as to whether these insects possessed one or two pairs of these 

 organs. 



It is remarkable that there is only one fragment of the wing of a 

 Dragon-fly ; this is the middle portion of a wing quite similar to 

 that from the Lower Purbecks figured in PI. XV. fig. 5. 



The chief types exhibited by the other wings are given in the fol- 

 lowing figures : — 



PI. XV. Fig. 6. Upper figure — the small wing-cover apparently of 

 one of the CicadeUince. 

 Lower left-hand figure — the extremity of the 

 upper surface of the closed wing-cover of a 

 Reduvius 1
