personally feel any doubt. So far as we know, our three allied species, 

 of which Smithianm is one, never assume a banded livery, although 

 venusfus (variabilis, Schm.) has sometimes the apex of the abdomen 

 whitish, while the rest of it may be nearly black. It is an interesting 

 question whether the dark forms may be considered typical, and the 

 banded and pale ones varieties, or vice versa. 



Any one who has access to JBombus nests could do useful service 

 to science in collecting the extreme varieties from each, as it would be 

 interesting to know to what extent the races of the various species 

 keep distinct.

TRICHOPTERA COLLECTED BY DR. CHAPMAN AT THE 

 VARANGER FIORD. 



BY ROBERT MoLACHLAN, F.R.S., &c. 



Our friend Dr. Chapman was among the somewhat numerous 

 tourists who went to the Varanger Fiord (Finmark) this year on what 

 proved to be an abortive eclipse expedition. Before his departure I 

 requested him to collect any Trichoptera, &c., he might meet with. I 

 have received the results, through Mr. Tutt, consisting of about 

 twenty-five specimens of Trichoptera, and three or four Ephemeridce 

 (which latter are at present not worked out). The Trichoptera are 

 as follows : — 



Limnophilus femoratus, Zett. Thirteen examples, or more than half the total, 

 of small size, and of the form that resembles the typical condition of L.fuscinervis, 

 Zett., very closely, though differing vastly in structure. My suggestion (Revision and 

 Synopsis, p. 73) that it is only in the S that the femora are dark appears to be quite 

 justified by these individuals. 



Limnophilus griseus, L. (et auct.). One small ^ . 



Asynarchus. Two ? apparently belong here, and as two species, but their 

 determination remains doubtful in the absence of the $ . 



Micropterna sequax, McL. One $ . 



Halesus te.isellatiis , Ramb. One S ■ 



Apatania stigmatella, Zett. One 9 , slightly doubtful. 



Molanva palpafa, McL. One ? . 



Sydropsi/che nevce,Ko\.,\a.r.feunica, McL. One <J . 



Plectrocnemia conspersa, Curt. Two ? . 



Rhyacophila nubila, Zett. Two $ . 



Of the above-named ten or eleven species, L. gri.ieus, M. sequax, M. palpata, 

 and P. conspersa, occur in Britain. 



The specimens were all collected between August 4th and 9th, at 

 Elvenaes and Yadso, which lie on the south and north sides of the 

 Fiord respectively, but I am unable to state the exact locality of each 

 individual, a matter not of much importance.
