THE HYMENOPTERA OF SUFFOLK.

[Colonel Hawley kindly presented us with a dozen cocoons, each pierced near one extremity by the circular hole whence had emerged singly both sexes of the above parasitic Braconid, which proves upon examination to be a species of Rhogas as anticipated (Trans, iii, 196 where read Jubbulpore throughout for Tubbulpore) and has been described (Entom. 1937, p. 255) by us as Rhogas siccitesta, sp. nov., because it emerges from the indurated husk of its host's larva. It is a solitary parasite of D. nerii, L., showing no indication of its presence tili the laiter's Caterpillar is or two inches in length : " I saw no parasite laying eggs in these larvae," the Colonel says in lit. Sept. 1936, but they were already attacked when I found them about one or \ \ inches long and looking quite healthy. Soon after that they collapsed suddenly and became brown over the three or four central segments, but remained fixed to their fulcrum. In a few hours the anterior five or six segments became detached and feil to the ground, leaving the posterior ones still in situ to form the ' cocoon ' for the parasite's pupa, whose larva is a greenish-white creature fully a quarter-inch in length." T h e whole process is obviously analogous to that of British species of this genus, especially Rhogas prertor, Reinh., which thus slays the allied Smerinthus populi, Linn.—Ed.]

[The British species of this interesting family are sadly in need of reVision. Marshall's 1872 Catalogue enumerates six kinds, ofwhich the two Evanice are no more than introductions from abroad and, in the course of a half-century's collecting, I have seen nothing like either or Fcenus erythrostomus, Dahl. T h e other two Fcenus are ubiquitous and I possess Hyptia minuta„ With the completion of this computation of our Hymenoptera, it may , w e U t o succinctly state that well over E I G H T AND A H I L F T H O U S A N D insects are now specifically recorded from Suffolk. This is a satisfactory increase of nearly a thousand beyond the figures (Trans, i, P . 10) known the tlme of this Society's inception ; and may be shown thus : — 1929 1937 Coleoptera . . 2052 2112 (Trans, iii, 186).

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.
