•64 THE FAUNA OF SCOTLAND. 



Family: SIRICIDAE. 

 Tribe: XIPHYDRINA. 



Genus : XIPHYDRTA, Lin. 



1 X. CAMELUS, Lin. 



"South of Scotland" (Stephens 111. Brit. Ent., vii.). I have never 

 «een this species myself in Scotland. 



Tribe: SIRICINA. 



Genus : SIREX, Lin. 

 Slrcx f/i'(/cis, Lin., and S. jiivencus, Lin., have both been found in 

 numerous localities in Scotland ; but as they are so easily introduced in 

 timber from other countries, I am not in a position to say that they 

 are really native. Certainly, the vast majority of the specimens of 

 ,gigc(s are importations from Norway and Svveden. I have a specimen 

 of 'S'. gigcis from Port-Glasgow with the pronotum yellow. American 

 species are occasionally introduced — e.g. , >S'. albicornis, 



CYNIPIDAE. 



In the Transactions of the Glasgow Society of Field 

 Naturalists, 1874, p. 44-51, I gave a catalogue of the gall- 

 making Gynipidae known to me at that time to inhabit 

 Scotland, enumerating 31 species (or rather species as then 

 regarded). Two years later, in Lists of the Fauna and 

 Flora of the West of Scotland (British Association Guide), 

 p. 17, this list was increased to 41 species (so-called), and 

 in addition catalogued 45 inquiline and parasitic species 

 for the West of Scotland. Since that time the observations 

 of Dr. Adler have completely revolutionised our views of the 

 species and genera of the gall-making species, — and in the 

 present catalogue the species are regarded from a totally 

 different standpoint. It is now known beyond dispute that 

 the species of gall-making Cyoiipidae fall under two divisions, 

 — one agamic — the other with an agamic autumnal brood, 

 followed by a spring bi-sexual brood, each differing greatly
