P. scuteUaris Thorns.). It was unknown in France in 1908, and does 

 not appear to have been noticed elsewhere. 



From Britain I have seen five females : One was swept from rank 

 herbage in Tuddenham Fen in Suffolk on Sept. 26th, 1907 (Morley) ; 

 one taken at Hastings during the same month (W. Ollis) ; one at 

 King's Lynn on August 19tli, 1908 (E. A. Atinore) ; one at West Stow 

 in Suffolk on July 2-ith, 1913 (Col. Nurse) ; and one near Nottingham 

 (Prof. Carr). It remains with students of the Tenthredinidae to 

 discover its exact hosts. 



In the British Catalogue of 1915 this species should be placed 

 as 1141a. 



2. — Ichneumon militaris Grav. (Ichn. Brit, i, p. 134). 



I have at length had the pleasure of seeing an indigenous specimen 

 of this insect, not recorded hence since Stephens' days. Wesmael alone 

 has told us anything reliable respecting its relationship, and this is 

 stated in Ichn. Brit. Both Berthoumieu and Schmiedeknecht con- 

 tinued to regard it as distinct from I. extensorius Linn., because they 

 considered it probable that the hind coxae bore no scopulae. This, 

 however, is not the case ; the scopulae are precisely as in the Linnean 

 species, from which it differs solely in having the mandibles, palpi, 

 and whole hind legs black. I can even discount Grravenhorst's dis- 

 parity of four lines, for the present example is fully 10 mm. in length. 

 It has the front tibiae internally pale. We must, consequently, 

 consider this form no more than a dark variety of I. extensorius Linn. 

 The Eev. W. F. Johnson, M.A., captured a single female in a 

 field at Poyntzpass in Co. Armagh, on August 15th, 1914. 



3. — DiCAELOTUs PusiLLATOK Grrav. (Ichn. Brit, i, p. 277). 



Gravenhorst brought forward a new species of Ichneumon under 

 the name I. pusillator, with no sex stated, in the Vergl. Ubers. Zool. 

 Syst., 1807, p. 260, and assigned both sexes to it in his Ichn. Europ., 

 1829, p. 605. [His description is copied by Eatz. Ichn. d. Forst. as 

 representing both sexes of an Ichneumonid bred by him from the same 

 host as Grravenhorst's var. 3 ? , namely Cossus ligniperda — Bombyx 

 cossiis at vol. iii, p. 257 — but I have no faith in the synonymy of his 

 with the oi'iginal species.] In 1859, Wesmael examined the types of 

 Graveuhorst's sexes and assigns (Mem. Couron. Ac. Belg., p. 75) the(^ 

 to a species earlier described by the same author ; but retains the $ , 

 as a good species, with the single remark " Quant a la femelle, je suis
