There are four Scandinavian species of this genus, namely, M. 
Ictodact^jlus, M. serotinus i^bipunctidactylus), M. pterodactyUs. Lmne 
3r Herr Wallengren believes our fuscus to be the pterodaciylus of 
inn6) and M. paludicola, Wallengren. Our British species are more 
umerous, viz., M. plagiodaotylus, M. serotinus, M. Hodghnsom, M 
.emi, and M. fuscus, five in number; it is probable, however, that 
.uch confusion exists in collections, with regard to this group. Sero- 
inns and Loewii from different localities need special examination, and 
t would be conferring a great favour on me if entomologists who take 
,ny species of this genus would lend me specimens for comparison. 
M mictodactylus should be carefully looked for in England; the larva 
feeds on Sa.ifraga granulata, a plant which in many localities is common 
in our island ; and the moth flies in May and June. This plume would 
make a splendid addition to our lists ; it is a large insect, nearly the 
size of fuscus, and more resembling plagiodacfylus than any other of
