Neuroptera. — This heterogeneous group has been only 

 partially listed in print. Eeference has already been 

 made (p. 50) to King and Morton's preliminary list of the 

 Trichoptera (caddis-flies) in the " Insecta Scotica," and as 

 regards the Dragon-flies, they have recently been the subject 

 of a paper by myself in our Proceedings} For some time past 

 I have been working at the ^N'europtera as a whole, and have 

 now, with Mr Morton's help, a list of 226 species, made up 

 as follows : — Mallophaga 45, Pseudo-Neuroptera 48, Odonata 

 11, Planipennia 27, and Trichoptera 95. The curious Boreus 

 hyemalis (L.) I have met with on a good many occasions,^ 

 and in Trichoptera it has been my good fortune to take 

 Halesus guttatipennis, M'L., Limnophilus hirsutus (Pict.), 

 Bhyacophila munda, M'L. (the first and third additions to the 

 Scottish list), and Tricenodes reuteri, M'L., new to Britain.^ 



Hymenoptera. — Despite its extreme interest, the difficulties 

 that beset the investigation of this large and bewildering 

 order have deterred most of our entomologists from working 

 at it. The Sessiliventres, or Saw-fly division, has received 

 some attention from myself, the result, so far, being a list of 

 80 species, or about 60 per cent, of what may be expected 

 to occur in the area. To the aculeate section (bees, wasps, 

 and ants) of the Petiolata, I have given much more attention, 

 and have now, awaiting an opportunity for publication, a list 

 of 115 species, which cannot be far short of the total. This 

 includes a few for the knowledge of which we are indebted 

 to Mr A. E. J. Carter, who has also worked at the Aculeata 

 of the district.^ Of the few British Chrysids, I have met 

 with only two here (see Ann. Scot. Nat. Hist, 1901, p. 118);

 xvi. pp. 87-96 (1905). 



2 Ann. S. N. H., 1897 and 1898. 



3 Morton,^, M. if., 1906, pp. 65, 270; and Evans, ^. ^.iV. 1906, p. 56. 

 ^ Some years ago I submitted a preliminary list of our Aculeates to this 



Society, but being manifestly incomplete it was not published. Many of my 

 records, however, in this and other groups of the Hymenoptera have appeared 

 in recent vols, of the Ent. Mo. Mag. (1900, etc.) and Ann. S. N. H., 1S99, 

 etc. ; also in Morley's work on British Ichneumons. Carter's records are in 

 the first-named magazine, and Trans. Scot. N. H. Soc, 1901. In the old 

 Entomological Mag., iv. (1837) pp. 226, 235, Halliday recorded one or two 

 Braconids from near Edinburgh. For much help in the determination of my 

 Hymenoptera, I am indebted to Kev. F. D. Morice, E. Saunders, C. Morley, 

 and A. J. Chitty.
