problems. Had I had more time to devote to them I might have 
taken more than I have, and probably other species :—Sericoris 
lacunana var. herbana, Mixodia Ratzburghiana, Pedisca occultana, 
EKupecilia udana, E. flaviciliana, EL. ruficillana, Cochylis gigantana, 
Depressaria rotundella, Yponomeuta evonymella, Cedestis farinatella, 
Gracillaria ononiella (one, which afterwards escaped), Coleophora 
conyz@, Batrachedra pinicolella, and Chauliodus iligerella.—

DorTHESIA CHITON IN IRELAND.—When in Greenland, during 
the summer of 1875, and searching for the “neat little snail,” 
Vitrina angelice, Bk. & M@ll., at the base of a cliff in English- 
man’s Bay, Disco, amongst a luxuriant growth of Platanthera 
hyperborea, Luzula spadicea, and Polystichwm lonchitis, my atten- 
tion was attracted to a number of small scaly insects which were 
adhering to the bases of the stems and dead leaves, amongst which 
the plants were growing. These proved to be the interesting and 
curious Coccus cataphracta of Shaw, to which the name of 
Dorthesia urtice, Linn., has been recently bestowed, and which 
is enumerated in the Appendix to Nares’ ‘ Polar Voyage’ as Dorthesia 
chiton, Zett. It was with much surprise and pleasure that, soon 
after my return from the Arctic Regions, while I was again 
hunting for small land-shells, this time at the roots of ivy and 
London-pride saxifrage (Saxifraga umbrosa), in a rocky glen at 
Glenalla, in the County Donegal, I again came upon a very 
numerous colony of the Dorthesia, which I have observed to 
continue in the same spot for the last three years. More recently 
I have observed this remarkable insect amongst moss and dead 
leaves in the “‘ Devil’s Glen,’ County Wicklow. Not feeling sure 
of the name I applied to Dr. F. Buchanan White, of Perth, who 
has lately described a Scottish species under the name of Orthezia 
Signoretti (see Scot. Nat. iv. 161), and he kindly informed me 
that he believes mine is the same species; but I find, from infor- 
mation kindly supplied by Mr. J. W. Douglas, that Signoret, the 
best authority on the subject, refers the three first names to one 
single species, in which probably D. Signoreti itself would be 
included, so that I am content with the expressive name of 
D. chiton, Zett., under which I first made acquaintance with the 
insect.— Henry CurcHester Harr; Royal Dublin Society, Kildare 
Street, Dublin, Oct. 21, 1880.
