would specially direct attention, these being new to science. 
The first is described by Mr Cambridge in an Appendix to 
the present paper, the second in the current volume (xv.) of 
Proceedings Dors. Nat. Hist. and Antig. Field Club, and the 
other two in the Annals of Scot. Nat. Hist. for January last. 
Taking Mr Cambridge’s Scottish list (Hntomologist for 
1877) as a basis,! and adding the additional records contained 
in his “ Spiders of Dorset,” and in Mr H. C. Young’s com- 
munications to the Proceedings of the Glasgow Natural 
History Society (vols. iii. and iv.), also those contained in 
the present paper, and one or two others, we find that the 
number of species known to inhabit the northern kingdom 
is slightly over 250—equal to about 48 per cent. of the 
530 or thereby on the British list at the present time. We 
may be sure this is nothing like the total spider fauna of 
North Britain, but how far it falls short of that total it is, of 
course, impossible to say. Some light, however, may perhaps 
be thrown on the point by a statement of the proportions 
which Scottish lists bear to the British ones in other branches 
of invertebrate zoology. ‘The three terrestrial groups of 
Invertebrata which have attracted most attention in Scotland 
are Lepidoptera, Coleoptera, and Jand Mollusca. Unfortu- 
nately no general list of Scottish Micro-lepidoptera has yet 
been published, and local lists are few and mostly very 
incomplete: the figures we cite apply, therefore, to the 
“Macros” only. It is worthy of note, however, that the 
late Sir Thomas Moncreiffe, who collected Micros with as 
much zeal as Macros, records 309 of the former against 294 
of the latter for the locality he specially worked, namely, 
Moncreiffe, near Perth; and he expressed the opinion that 
many micros still remain to be added to the list (Scot. Nat., 
vols, iv. and v.). 
According to South’s “ Synonymic List” (1884) the number 
of British Macro-lepidoptera is 817, of which 494, or fully 
60 per cent., are entered in Dr Buchanan White’s “ Lepi- 
doptera of Scotland” (Scot. Nat., vols. i-v.). The number 
of beetles described in Fowler’s recent work (“ British

are excluded for the purposes of the present inquiry,
