MISCELLANEOUS NOTES AND OBSERVATIONS. 
Paradoxocarpus carinatus, Neiiring. — Referring to my paper 
on Paradoxocarpus carinatus in our ‘ Transactions ’ (vol. v. p. 382) 
it has recently been discovered by Dr. K. Keilhack that the much- 
debated fruit, not uncommon in the Cromer Forest-bed, is that 
of our Water-aloe, Stratiotes aloides ( sec ‘ Xaturwissenschaftliche 
Wochenschrift,’ IStli October, 1S96). Dr. Keilhack has kindly 
sent me ripe fruits of the recent plant, and these leave no doubt 
as to .the correctness of his determination, which is also accepted 
by Professor Nehring. I have never been able to obtain ripe fruits 
of Stratiotes in this country, and in Germany also it does not 
appear to fruit at all freely. The determination of this plant 
makes it probable that the species of Folliculites, so common in 
Eocene and Oligocene strata, belong also to the isolated and 
essentially aquatic order of the Hydrocharidece. — Clement Reid. 
Aculeate-ITymenoptera, at Tostock near Bury St. Edmunds. — 
During the past autumn I had some very profitable field work — 
in spite of a wet September — and I give a list of my best 
captures. I added five new species to my parish list of Aculeate- 
Hymenoptera, viz. : — 
Ceropales maculatus, Fab. August 4th, on Wild Parsley. 
Mimesa equestris, Fab. July 26th, in a sand-pit. 
Crabro anxius, Wesm. August 11th, on Parsley. 
Andrena gwynana, var. bicolor, Fab. August 5th, on Bramble 
bloom. 
Caelioxys elongata, Lep. August 5th, on Wild Bryony. 
This brings my list up to 181, viz., Ants 9, Fossores 52, 
Wasps 13, Bees 107. 
In studying this subject I have from time to time found and bred 
from the various nests examined many rare Diptera. This long
