S • Colour shining dark blue-black, without any tinge of green : thorax and 
abdomen marked as in the two preceding species, but having the latter less tessellated 
with white : head as in M. simplex, the eyes near together, though not contiguous : 
le & s, fou femora ciliated with a comb-like row of bristles on their under surfaces, as 
m M. simplex ; fore tibia? nearly bare ; middle legs armed as in M. hortorum, and 
also with a bristly tubercle seated on the outer side of the head of the tibia ; hind 
tibiie a little curved, clothed with long soft hairs on their outer sides : alulets with 
the lower scale of an uniform brownish-yellow colour : wings tinged with brown at 
their bases and along the fore borders, the longitudinal veins also a little clouded ; 
the third longitudinal vein armed at the base with a few spines, as in M. simplex : 
the ^ is unknown to me. 
This % has not yet been found in Britain, but inhabits lofty 
mountains in (xermany, where it is said to be not uncommon. It is 
the largest species in the genus, and is of rather a darker colour thau 
the others ; I have not seen a female, but my friend Mr. Kowarz, of 
Franzensbad, kindly sent me a male specimen.

this species varies a good deal in colour, it is less brilliant and less distinctly 
striped and tessellated than either of the preceding ones, though marked in the 
same manner ; there is often a greyish, and sometimes an eeneous tinge on the ab- 
domen, and the thorax is less blue than black ; the $ has the eyes somewhat widely 
separated ; the fore femora are ciliated beneath as in M. simplex ; the fore tibiie 
simple ; middle femora armed beneath at their bases with a single long strong spine, 
and with a few long bristles on their outer and under surfaces near their apices ; the 
middle t-ibias have an angular bond in the middle, the lower halves being directed 
outwards, they are also ciliated along their whole outer surfaces with little stiff 
rough spines, similar to those seen in M. hortorum and J I. podagrica ; the hind 
femora are evenly clothed along their whole under surfaces with hairs of a moderate 
length, and have a tuft on their upper surfaces near the base ; the hind tibia? are 
rather long and strongly curved inwards ; they are bare on their inner sides, with
