54: THE FAUNA OF SCOTLAND. 



rare and local in their habitats, are not likely to occur in 

 both countries from causes which we are unable to explain ; 

 that many species — boreal and alpine — are not likely to be 

 found in England, judging from their Continental range ; and 

 lastly, that numerous species of Southern genera (Macro- 

 phya, &c.) may confidently be expected, if we may judge 

 from their general distribution, not to extend northward 

 beyond the Midland Counties of England. 



I do not expect that further research will show much 

 difference in the relative numbers of the species found 

 inhabiting the two countries ; for, if I mistake not, about 

 two-thirds of the total British species is the proportion in 

 other groups of insects found to inhabit Scotland. 



In the catalogue the additional species only are numbered. 

 I have indicated such changes as have been made in nomen- 

 clature, and have given new localities for the rarer species. 



Genus: TENTHREDO. 

 8.* SCOTICA, Cam. 

 Rare. Dumfries. 



T. ZONATA, Pz. 



This name is changed to the earlier one of maculafa, Fourc. 



T. OBSOLETA. 



Castlecary Glen. 



T. VIRIDIS. 



This is jncta, Kl., as stated, but is not, I now believe, the true 

 viridis^ Lin., that being probably identical with scalaris, Kl., No. 13. 

 T. picta I have found commonly at Thornhil!. 



TENTHREDOPSIS. 

 So many alterations and additions have to be made in this genus 

 that it will be best to give a complete revision of it. 



1. T. CORDATA, Fourc, 

 Common in Clydesdale and the West of Scotland. 

 Polmont, Kingussie. 



2. T. MICROCEPHALA, Lcp.
