254 THE SCOTTISH NATURALIST 



of pale. Var. smithianus occurs in Lewis, Shetland, and Norway ; 

 but in Orkney the specimens are intermediate between it and 

 typical nmscoriiin — compare the case o{ jone/h/s, above. An inter- 

 mediate between typical iinisconDn and var. smithianus has also 

 been taken in Scilly {teste Sladen, p. 200), and Perkins states 

 (in lit.) that a worker approaching smithianus was once taken at 

 Dover. Seven queens of suiithiauus were brought back from 

 Lewis. In Shetland Mr Morice found it nesting in stone walls. ^ 



Trichoptera. — The following species were determined by Mr 

 K. J. Morton : — Limnophilus sparsus, Lininophilus marmoratiis, 

 Stenophylax iatipennis, Sericostoma persouatuni, Leptocerus cinereus, 

 Mysiacides aziirea, Tinodes 7V(cneri, Polycentropus fl avomaculatus. 



Neuroptera (s.str.) are represented in the collection only 

 by a single specimen of the common Alder-fly, Sialis lutaria 

 (K. J. Morton det.). 



Plecoptera (Perlidas) are represented by Chloroperla gram- 

 matica (K. J. Morton det.). 



Odonata : only a single dragon-fly was preserved, a female of 

 Pyrrhoso77ia nyinphula^ Sulz. (F. Balfour-Brownc det.). 



SiPHONAPTERA. — The following fleas, collected by G. B. Hony 

 at or near Barvas have been identified by Hon. N. C. Rothschild : 

 Ctenophthalnius agyrtes, Heller, from Brown Rat {Epimys decu- 

 manus) and from Field Mouse {Apodemus sylvaticus liebridensis ?) ; 

 Ceratophyllus fasciatus, Bosc, from same two hosts ; Doratopsylla 

 dasycnemus, Rothschild, from Field Mouse. The sub-species of 

 Field Mouse is in all probability A. sylvaticus hebridensis ; the 

 specimens will not, however, be critically determined till Mr Hony 

 returns from the war. 



^ In the June number of the present volume, p. 1^4, the following bees are 

 recorded from the Butt of Ltwis, Sejitember 1914 : Bomhus litcorum, B. muscoruni 

 var. smitliiamis^ and B. distinguendus Mor. The last was not obtained by the 

 Cambridge party in July. It is of more frequent occurrence in the north than 

 in the south of Great Britain, and has been recorded from North Uist (Sladen, 

 p. 187).
