The Scottish Naturalist. 



Liodes GLABER, Kug.— Frequents a peculiar fungus growing on 

 the old stumps at Rannoch and Strath Africk ; the larva 

 has been described by Schiodte. 



L. castaneus, Herbst. — Found with the above at Rannoch, in 

 similar circumstances ; larva described by Perris. 



Agathidium rotundatum, Gyll. — Sparingly under the bark of 

 the fir at Rannoch and elsewhere \ larva unknown. 



A. rhinoceros, Sharp. — This was once found by me in abun- 

 dance under the bark of a dead fir at Rannoch ; besides 

 these specimens only one other is known, which was captured 

 by me with the sweeping net at night, in Strath Africk, in a 

 locality where the Scotch fir grows \ hence, I suppose it to 

 be attached to this tree. The earlier stages are unknown. 



A. nigrinum, Sturm. — Found with the species of Liodes at 

 Rannoch. Thomson says it inhabits, in Sweden, leaf trees 

 (in opposition to fir trees), but I am not quite sure that 

 there may not be two species yet confounded under the 

 name of nigrinum ; observations of the history of the species 

 would help to clear up this point j the earlier stages are un- 

 known. 



Pteryx suturalis, Heer. — This little creature is found under 

 the bark of the fir stumps at Rannoch ; its life history is 

 unknown. It is the only bark Trichopterygian as yet found 

 in Scotland. 



Epur.«a angustula, Er. — Found under the bark of fir at Ran- 

 noch ; its larva and habits are quite unknown, but I suppose 

 it to live at the expense of Xylotcrus lincatus. 

 E. pusilla, Herbst. — Abundant through the country, under the. 

 bark of felled Scotch firs ; the larva of this, and also of the 

 following species, are quite unknown. 

 E. oblonga, Herbst. — Only a very few examples of this species 

 have occurred in Britain, all found under bark of Scotch fir. 

 First taken by myself and others near London, and subse- 

 quently by Mr. Crotch, on the Cheviots, near Yetholm. 

 Ips quadripustulatus, Fab. — This species is abundant under 

 the bark of the fir stumps at Rannoch, and is found else- 

 where. The larva is carnivorous, and has, I believe, been 

 described by Frisch. Thomson says, that in Sweden this 

 species inhabits leaf trees as well as fir, but my experience
