Tisvheria complanella, lib., coiiiiiioii, Croftluigcii and Quarry Woods. 



Lithocolletis irradiella, Scott, scarce, Crofthugon. vacciniella, Scott, Leven- 



side Moor. cerasicolella, H.-S., scarce, mines in the leaves of wild cherry, 



Crofthugen. spinicolella, Kol., common on sloe, Quarry Wood. -oxyacanthce, 



Fi'cy., most abundant everywhere on hawthorn ; most of the mines examined on 

 the hedges bordering the road between Bonhill and Dumbarton contained parasites, 

 but the iiedges dividing fields yielded a very small percentage of affected specimens. 



sorbi, Frey, very common on rowan, also subject to the attacks of parasites. 



There is a large form which occurs in the Quarry Woods which agrees but poorly 

 with the types of sorbi, or even with the specimens which I have bred. There is a 

 species belonging to the group containing tiie four foregoing species which occurs on 

 Pyrus mains, but so far 1 have failed to obtain the imago. I have not the least 

 doubt that it is a different species from those recorded. coryli, Nicelli, Croft- 

 hugen. -faginella, Zell., very abundant on beech.- ulmifoliella, Hb., not un- 

 common on birch, much darker than southern specimens. spinolella, very com- 

 mon on sallow, darker than English specimens. quercifoliella, Fisch., abundant 



on oaks. messanieUa, Zell., not common, Dillichip ; have bred this species from 



beech. corylifoUella, Haw., scarce, Crofthugen. betulcB, Zell., scarce on birch, 



Quarry Wood. ahiifoliella, fib., very abundant on alder, Crofthugen and Leven- 



side. Ileegeriella, Zell., not uncommon. Quarry Woods and Levensidc. 



Cramerella, Fb., common everywhere on oak.- emberizcepennella, Bouche, not 



common, occurs on honeysuckle, Croftliugen and Quarry Woods. Frolichiella, 



Zell., not uncommon on alder, Crofthugen. Nicellii, Zell., abundant among hazel 



in Quarry Woods and Crofthugen. — —s^e/i««eHS!s, Nicelli, Crofthugen. Kleeman- 



neJla, Fb., not uncommon, Crofthugen, one specimen uncommonly dark. 



Lyonetia Clerckella, L., not uncommon, one specimen of the suffused variety 

 off rowan, Crofthugen and Levenside. 



Cemiostoma spartifoUella, Hb., abundant on broom. laburnella, Heyd., 



scarce, Dumbarton Road. 



Oposteya crepusculella, Fisch., Levenside Moor and Quarry Woods, scarce. 

 Bucculatrix nigricomella, Zell., Levenside. 



Nepticula atricapitella, Haw., Crofthugen. rvficapitella. Haw., Crofthugeu. 



Fletcheri, Tutt, Crofthugen. argt/ropeza, Zell. {apicella, Sta.), Crofthugen. 



floslactella, Haw., common everywhere. argentipedella, Zell., scarce, Croft- 

 hugen. plagicolella, Sta., Crofthugen. gratiosella, Sta., off Hawthorn, Dal- 



monach. 



Trifurcula immundella, Zell., very common everywhere. pulterosella, Sta., 



scarce, Levenside. 



Most of the species in the above list have been identified by either Mr. C. G. 

 Barrett or Mr. E. R. Bankes. I therefore desire, in conclusion, lo thank them for 

 their kind assistance, and beg to express the hope that the list, however incomplete it 

 may be, will prove of service to those interested in the distribution of our Micro- 

 Lepido'ptera.
