Colour and pattern the same as in M. simplex, but the abdomen has more fre- 
quently a green tinge : head — eyes of 3 parted by a black space, which occupies 
about one-eiglitli of the width of the head, and is about twice as wide as the interval 
between the eyes of M. simplex ; the space between the eyes of $ measures one- 
third of the width of the head, characters of the other parts of the head similar to 
those of M. simplex : thorax and abdomen marked as in M. simplex : legs with fore 
femora ciliated beneath with long stiff hairs, in addition to which (in the 3 ) they 
are thickly bearded on the outer and under sides with soft hairs ; fore tibiae of 3 
with a few long stiff spines on their outer surfaces near the middle and at the ex- 
tremities, and with their inner sides clothed along the whole length with thick, soft, 
and rather short hairs ; middle femora armed in 3 with a tuft of short but stiff 
bristles near the tip ; middle tibiae with a series of short erect little spines, placed 
irregularly along the upper half of the outer surface, and having the lower half of the 
same surface fringed with soft short hairs, as in M. simplex ; hind femora with only 
a few long hairs on their under surfaces near the ends ; hind tibiae slightly but dis- 
tinctly curved inwards at their lower thirds, they have a thick row of short stiff 
bristles along their outer sides, and only a few short soft hairs on their inner and 
under surfaces ; hind tarsi as in M. simplex : alulets dirty white, lower scale in 3 
having a brown tinge in the form of a ring, near the margin, the edge itself being 
fringed with pale yellow : wings clouded near the base with brown, which colour is 
conspicuous in the small basal cells : third longitudinal vein armed with six or seven 
small spines, which are arranged along the vein at nearly equal distances, and extend 
from the base to near the small cross vein in 3 and ? . 
This species is rather larger than the former, -and very common ; 
the males may at once be distinguished from those of the preceding 
species by the tuft on the apex of the middle femora, by the wider 
space between the eyes, and by the anterior ti bine being hairy on their 
inner sides instead of the posterior ones, as in ill. simplex ; also by the 
spines on the wings. The females of the two species (which authors 
have failed to discriminate) may most readily be known from each 
other by the difference in width between the eyes, by the hind tibine 
in M. simplex being clothed beneath with a few r long hairs (which are 
absent in M. hortorum), and by the different armature of the third 
longitudinal veins of the wings.
