sculpture, which in numerous forms attains a condition of 

 elegance well worthy of attention. There are nearly 300 species 

 known, and in Britain we have about a score. The characters 

 we have given above do not apply to the genus Fiesma, though 



it is usually placed in 

 this family ; its scutel- 

 lum is not covered, and 

 ocelli are present. Al- 

 though but little is 

 known as to the nature 

 of the lives of Tingidae, 

 yet it was pointed out 

 long ago by Keaumur 

 that a species of the 

 family (probably C. elari- 

 corne, Fig. 263), lives in 

 deformations of the 

 flowers of the Labiate 

 plant now called Tcucrium cliamacdrys ; Frauenfeld has more 

 recently confirmed this observation, and shown that the closely allied 

 C. teucrii affects the flowers of T. montamim in a similar manner.^

 middle of the prosternuni. — These very flat Insects,of obscure colour, 

 have frequently very peculiar sculpture. They live under bark, or 

 on funo;i growing from bark, and 

 are supposed to draw their nut- 

 riment from the fungi, though 

 but little is actually known as 

 to their natvo-al history. The 

 family is almost cosmopolitan, 

 and includes about 3 species, 

 of which five occur in Eng- 

 land. The small sub -family 

 Isoderminae consists of a few 

 species that are placed only
