A HISTORY OF HERTFORDSHIRE CAMPTOSOMATA (continued) Cryptocephalus moraei, L. Tring, scarce, on Hypericum perforatum fulvus, Goeze. Wihtone, rare frontalis, Marsh. Chipperfield (Piffard) labiatus, L. Tring CYCLICA Lamprosoma concolor, Sturm. Tring, rare Timarcha tenebricosa, F. Tring, very common. This species is certainly attached to species of Galium ; I have repeatedly noticed the larvae feeding on Galium mollugo, in hedgerows near the town violaceonigra, De G. Aldbury, not very common Chrysomela marginalis, Duft. Aldbury, very scarce, on Linaria vulgaris staphylea, L. Tring and Hastoe polita, L. Tring, very common. Doubtless this insect prefers to feed on various Labiate plants. I have found it, both as larvae and imago, swarming on Mentha aquatica in marshy spots, and on Origanum vul- gare in dry chalky situations varians, Schall. Tring gcettingensis, L. Wigginton, one only, walking on roadway didymata, Scriba. Hertford (Stephens) ; Baldock (Wood) hyperici, Forst. Tring, on Hypericum perforatum Phytodecta rufipes, De G.

Tring Galerucella viburni, Payk. Tring, rare, on Viburnum opulus nympheae, L. Wihtone, rare sagittariae, Gyll. Wihtone, plentiful in marshy spots by the reservoir ; have seen six or seven hibernating to- gether in one dead reed stem tenella, L.

Little Tring holsaticus, L. Wihtone quadriguttatus, Pont. Hertford (Ste- phens) luridus, Scop. New Barnet (Newbery); Tring, very common, and extremely variable as to colour, a light tes- taceous form being very often met with on the hills, and a very dark (almost black) variety which occurs more often in damp situations brunneus, Duft. Tring agilis, Rye. Baldock, one specimen only (Wood) suturellus, Duft. Tring, fairly com- mon on various species of Senecio atricillus, L. Tring, common, and apparently fond of Labiate plants as well as Leguminous ones melanocephalus, All. Tring atriceps, Kuts.
