I ought perhaps to state that in this short catalogue I have admitted only those species which I have observed to be more particularly abundant in the neighbourhood.

Note on the Larva of Cis Boleti. The larva is white, shining, semitransparent, cylindrical, longer and more slender than the perfect insect, but much resembles it in its movements, having the same habits and dwelling.

The twelfth and thirteenth segments are pale brown above, and the last is armed with two dark brown spines, bending upward.—Francis Walker; Southgate, January, 1843.
