I mention here that I have lately discovered the ' Insect- 

 limestone ' in the outlier at Copt Heath, near Knowle, where 

 I had previously expected its occurrence. It lies in detached 

 pieces, a few large blocks being found, about three or four 

 inches thick, scattered about over the fields, and seems to be 

 near the surface; but no section is exposed. The other 

 argillaceous and calcareous bands, notably the firestones and 

 guinea bed, were formerly quarried by a shaft of some 

 depth, and afforded Ammonites planorbis, Ostrea liassica, 

 Modiola minima, Cardium, Lima punctata, spines of Cidaris, 

 fish scales, and bones of Ichthyosaurus. 



From the 'Insect bed' I obtained a small beetle, elytra of 

 Coleoptera of several genera, wings of Orthophlebia com- 

 munis, Diptera, Orthoptera, and Neuroptera. Whether only 

 one or more of the several beds of Insect limestone are 

 present here, as at Wilmcote and Binton, it is impossible to 

 say, as no section is anywhere visible. 



As this is the most northern limit of the Rhcetics in 

 Warwickshire, so it is of the lowest zones of the Lias in 

 that direction. At. Brown's Wood and Stooper's Wood in 

 the neighbourhood of Henley-in-Arden the insect bed is 

 very hard, compact, and crystalline, and contains a great 

 variety of beautifully preserved insect remains, including 

 several fine beetles, (Elateridce or Telephoridce), elytra, 

 wings of Diptera, Blatta, Neuroptera, (including Libellula, 

 Ephemera, and Orthophlebia), Orthoptera, and some remark- 

 able Trichopterous wings and a curious fossil, supposed, by 

 a competent authority, to be the male organ of a Neurop- 

 terous insect. Many of these appear to be new; a few 

 fragmentary plants (including fronds of fern), and a small 

 shrimp-like Crustacean are associated with them.
