67 
and 3 lines long, the male distinguished by the cheeks, hypopygium, fore 
and hind thighs, and middle tibiae being pectinated; generally found on 
fungi in the northern provinces. Ampycophora Wlbg., identified by 
Zetterstedt with Aulacigaster Macquart. Earomyia , like Lonchcea , face 
more prominent, eyes smaller; one species E. lonchceoides, 2 lines long. 
Anthophilina , synonymous with Leptomyza Macquart. Lobioptera 
Wlbg., allied to Milichia , but the fore edge of the wing with a deep in¬ 
cision at the end of the subcostal vein, and the costal vein vanishes before 
the end of the subapical; one species L. ludens Wlbg., 3^ line long. 
Selachops Wlbg., like Lonchcea , but the mediastinal vein indistinct, and 
the ovipositor not protruded, form of the head somewhat like Tetanops , 
the protuberant front overhanging the short antennae, the third joint of 
which is round, with the naked arista implanted towards the tip; one 
species S. Jlavocincta Wlbg. ( Eucoelocera bicolor Lw.), occurring in the 
northern and central provinces, and abundant on the banks of the Kiver 
Luleaa. And of the “ sections” of Stenhammar, but which are formally 
named and divided as genera, Parydra Stnh. is synonymous with Napcea 
Desvoidy, but the latter name pre-occupied in botany; Epipela Stnh. is 
Ilythea Hal. ; Philygria Stnh. is Hydrina Desvoidy, including Hyadina 
and Axysta Hal.; Clasiopa Stnh. is Discocerina Macq., as limited by 
Haliday, A.D. 1839. Hippoboscidle — Leptopteryx , of rather doubtful affi¬ 
nity, differing from the rest of this family by the distinctly triarticulate 
antennas without an arista, long slender legs, and wings not distinctly 
veined; L. nivalis , 1J lines long; a single specimen found crawling on 
the mountain snow in Lapland. 
Among the more remarkable species made known by Zetterstedt, 
are a species of Scenopinus , with the second branch of the cubital vein 
again forked, S. furcinervis , and an Echinomyia , with 4-jointed tarsi, 
E. tetramera . Only one specimen had occurred of each. May they not 
be symmetrical monstrosities, such as are not without example ? 
The space will not allow us to pass in review the multitude of species 
first made known in these volumes, or to indicate the synonyms of some, 
which appear to have been described before. We hope to see this yet 
done, as well for the “ Diptera Scandinavia,” as the “ Insecta Britannica,” 
when the concluding volume of the latter shall have appeared, since the 
collation of both works may lead to more satisfactory results. 
We have endeavoured to arrive at some estimate, of course a very pro¬ 
blematical one, of the relative numbers of Diptera in Sweden and in the 
British Islands. Walker, in a preface to the second volume of “ Insecta 
Britannica,” has expressed an opinion that the numbers may be about equal;
