THE HYMENOPTERA OF SUFFOLK
Fab. from Reigate (Chitty) and Shere (Capron) in Surrey, from Felden in Herts (Piffard), and Sandown in 1. Wight during August 1907 (E. A. Butler). A fiftb indigenous species, Foenus minutus, Tour., was brought forward in 1879 (Entom. xiii, 89); and recently (I.e. 1928, p. 190) Waterston calmly informs us that no less than six of Kieffer's kinds of Gasteruption (Latr. 1796, nom. nud. =Faenus, Fab. 1798) occur in Britain, but omitting all details of captors or localities. The family has been singularly unfortunate in its monographers : Tournier knew little of Hymenoptera in general, Kieffer is an acknowledged speciesspliter, and Waterston is—dead. lt is necessary, then, to explain vhat thefirstSuffolk kind has the oviposter as long as the whole body, the second less than half the abdominal length : both oviposit in the burrows of Pemphredon lugubris in my garden.] Fcenus jaculator, Linn.

Thesefive,with the Aulacid Trigonalys Hahni, Spin. (1840=Anglicana, Shuck. 1841) and Agriotypid Agriotypus armatus, Curt., constitute seve British species, of which Suffolk has only two.
