_Entomological Query_ (Vol. iv., p. 101.).--The insect which J. E. found
on the _Linaria minor_ is probably either the _Euphitecia Linariata_ or
_E. Pulchellata_. The former species is known to feed on Toad flax, and
there is little doubt that the latter does also. If J. E. found any of
the caterpillars he may identify them by referring to Westwood's
_British Moths_, vol ii. p. 59., where the caterpillar of _Euphitecia
Linariata_ is engraved and described as "yellow or greenish, with dark
chesnut spots on the back and sides."
