A HISTORY OF HERTFORDSHIRE ALEOCHARINA (continued) Gyrophzna minima, Er. Tring, usually in fungi on old stumps laevipennis, Kr. Tring and Aihridge lucidula, Er. Wihtone, very rare, two examples in refuse by the reservoir, April, 1 900 ; this species, unlike all other members of the genus, has not been found in fungi in this country manca, Er. Tring and Wihtone ; this insect seems very seldom to be met with in the south of England, and it is noteworthy that I have never met with it on the southern slopes of the Chilterns about Chesham, although it seems to occur pretty generally on the northern slopes of the range in the vicinity of Tring, only a few miles distant strictula, Er.
