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. A single specimen of Callidium variabile was also taken, but it is the only instance of which I have heard.—Vernon Wollaston; Jesus College, Cambridge, January 5, 1843.

Note on captures of Coleopterous Insects near Cambridge, in December, 1842, and January, 1843. Within the last six weeks the following Coleoptera, amongst many others, have been brought to me from the fens. Some of them have occurred in immense numbers, of these Thanasimus formicarius, Panagaeus crux-major and Opilus mollis ought to be more particularly mentioned.

Lamprias chlorocephalus Thanasimus formicarius Hylurgus piniperda
Leistus spinibarbis Opilus mollis Bruchus Pisi
Panagaeus crux-major Anobium castaneum Dorytomus pectoralis
Colymbetes guttatus tessellatum Saperda oculata
Oiceoptoma sinuata Hylesinus Fraxini

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 body is composed of thirteen segments, the first or the head is light brown, the eyes are like two black specks, the jaws and mouth are dark brown. The three following segments each bear a pair of short legs; the second or the prothorax is as large again as any of the following, which are nearly equal in size. 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.

Note on the capture of Coleopterous Insects during a flood. Although summer is the usual season for entomological excursions, every insect-hunter knows that if he is industrious much may be added to
