insect remains, twenty-two in number, was made by Mr. W. R. 

 Brodie, of Swanage. Professor Westwood states that these 

 remains included Elateridce, Helopidce, Curcul'miidce, and the wing 

 of a gigantic Ant, which, in its perfect state, must have measured 

 at least two inches across the expanded wings ; it is most nearly 

 allied to some of the exotic forms of which Myrmica is the type 

 in temperate regions. " The discovery of such an insect," says 

 Professor Westwood, " is of the highest importance in respect to 

 the question of the geographical range of the insects embedded in 

 the lower Purbeck series." The largest collection of insect 

 remains from the lower Purbecks was made by the Rev. 

 P. B. Brodie. " It consisted," says Professor Westwood, " of 

 three hundred and fifty small slabs of stone of various sizes. 

 Upon many of them only a single fragment of an insect occurs ; 

 but upon a considerable number, the remains are very numerous, 

 the fragments being crowded together, and often lying one upon 

 another." These remains, of course, included quantities of eljrtra 

 of Coleoptera, and also wings and wing covers of Neuroptera and 

 OrtJioptera, and two wings supposed to be Lepldopterous. The very 

 fragmentary nature of these insect remains rendered the identifica- 

 tion of the majority of them a matter of impossibility, but from 

 Professor Westwood's paper in the proceedings of the Geological 

 Society for 1854, and the list of species in Dr. Giebel's * " Fauna 

 der Vorwelt" some eighty-six species seem to have been 

 'determined, viz. : — 



Coleoptera 45 species. 



Orthoptera ... ... ... 12 



Neuroptera ... ... ... 10 



Hemiptera 11 



Diptera ... ... ... .■• 4 



Hymeuoptera 2 



(supposed) Lepidoptera 2 



86 



The two supposed species of Lepidoptera were respectively named, 

 by Professor Westwood, Cyllmium Boisduvatianum, and C. 



* Fauna der Vorwelt, pp. 187, 393, and 426.
