club-shaped, flattened at the sides. Wings somewhat short. Base 
of fourth hind areolet much nearer the base of wing than is base 
of the second hind areolet. Petiole of second hind areolet long. 
Fourth longitudinal vein short. Larvee live in fungi. 
E. fungorum, Dg. = M. fusca, Latr., Mg. 
This is a fairly common species. The larve living in the pileus 
of Boletus and other fungi. 
Imago dark-brown. Head brown, palpi and antennz yellowish- 
red; the latter dark-brown at the tip, very slender, and about the 
length of thorax. Thorax brown, tawny on each side; with 
grayish and small black hairs on parts. Abdomen blackish-brown, 
with tawny extremity. Pincers small and tawny. Wings with 
a brownish tinge; the veinlets of the pre-brachial areolet forming 
a slightly obtuse angle, the hind one much longer than the fore 
one, and about four times as long as the sub-apical vein before 
its fork. The anal (sixth longitudinal vein) does not extend as far 
as the fork of the fifth longitudinal vein. Legs pale yellow, slender ; 
tarsi brown; hind tibiz with minute spines and very long spurs.

M. guttiventris, Mg. 
L. lateralis, Mg. = { M. seriata, Zett. 
This is another fairly common British species. It is dark brown, 
with testaceous ventral surface.’ Head brown; antenne testaceous 
at base, dark brown at distal extremity, about as long as thorax. 
The thorax, which is brown, and covered in parts by minute gray 
and black hairs, is testaceous or tawny at the sides. The abdomen

third each forming a band above. The wings have the veinlets of 
the prz-brachial areolet forming a slightly acute angle, the hind one 
nearly eight times the length of the fore one; the anal does not 
extend to the fork of sub-anal. The legs are long and slender and 
testaceous ; spurs long; tarsi brown. Length 1} to 2 lin. 
These are the only two common species in this genus, but the 
following also occur in England: /eptura, Mg., dorsalis, Staeg.,

Wlk., and fuscula, Wik. 
Genus.—AVWodia. 
Slender, tawny or brownish-black genus. Antenne sometimes 
cone-shaped. Resembles Aymosia, but the petiole of the second
