(Stephens) ; Cambridge (Power). 
IVI. cicatricosus, Leach. Head and thorax black or bluish black, 
elytra bluish black ; head and thorax closely and strongly punctured, the 
intervals being closely rugose; antenne rather long and stout, not 
thickened in middle; thorax about as broad as head, evidently broader 
than long, with the anterior angles pronounced and raised, the sides 
subparallel, and the base broadly emarginate and furrowed before 
margin; there is a fine central line on disc and on either side towards 
margin a rather deep fovea ; elytra with closely set flat shining tubercles, 
the intervals between these being closely rugose ; abdomen finely rugose ; 
legs rather long and stout, bluish black or black. L. 12-32 mm. 
Male with the antenne longer than in female, and the last ventral 
segment of the abdomen semicircularly emarginate. 
Grassy banks, &c.; near the coast; in early spring ; extremely local, but sometimes 
abundant where it occurs; Southend; Margate and St. Peter’s, Kent (T. Wood) ; 
Ramsgate (in great profusion, Champion); Deal (Syme); Dover (C. G. Hall) ; Mr. 
Champion has remarked that the species is only to be found while the sun is out, and 
that if cloudy not a specimen will be seen: it seems strange that such large and 
conspicuous insects can so soon disappear without leaving a trace behind them of their 
place of refuge. 
M. variegatus, Donov. Of an obscure metallic greenish colour, 
with the margins of head and thorax coppery red, and the abdomen with 
the segments more or less coppery red at apex ; the reflections are more 
or less greenish, coppery or violet; head and thorax very closely and 
rugosely punctured, the punctuation being strong and more or less con- 
fluent ; thorax longer than broad, with the sides subparallel and the 
base broadly emarginate ; elytra sculptured in rough flat tubercles, the 
interstices being closely rugose; abdomen rugose; legs robust, bright 
coppery red. L. 14-30 mm. 
Male with the last ventral segment semicircularly emarginate. 
Female with the last ventral segment angularly emarginate in the 
centre and curved on each side of the emargination. 
On grassy banks and pathways near the coast in early spring; very rare; Isle of 
Tha et, between Broadstairs and Ramsgate (Stephens); Ramsgate (T. Wood) ; 
Marga ’e (three specimens in 1882, T. Wood) ; Dover (C. G. Hall). 
IM. rugosus, Marsh. (rugulosus, Brull.). This and the succeeding 
species may be known by their comparatively small size and narrow 
transverse thorax, which is considerably shorter than the head; dull 
black or greyish black, with the head and thorax closely and very 
coarsely punctured, the former large and the latter small and transverse ; 
antenne comparatively slender, rather long; thorax with the angles 
rounded, slightly narrowed behind, broadly emarginate at base, slightly 
furrowed before basal margin; elytra very coarsely coriaceous or rugose 
with the intervals finely wrinkled ; legs long and comparatively slender,
