Occm-rence in Bntain of Epuma silacea, Hbst-I have in my collecti 
example of this fine species, the largest of the European Ep^crcece, whichVas

July, 1866 (see Ent. M. Mag.. Vol. iii, p. 94), and appears at the time to 
suspected the. d^erence from large examples of i;. aeleta (a species varying 
Ihne to li hues) to which E. silacea is very closely allied, and from whi 
differs as foUows ; xt xs considerably larger (my specimen being rather over 2 
m length), proportionably broader, entirely yellow in color (.•. .., there ar 
xnfuscate vaneties of it), rather duller, on account of its closer punctuation 
Its thorax IS more rounded towards the front from the lower third. In the , 
moreover (to which sex my specimen belongs), the middle tibi^ are sli, 
widened and bent inwardly just before the apex ; the corresponding memb 
the same sex of deleta being quite straight inwardly, and only exhibiti, 
rectangular pomt at the outer apex, which is obtuse in silacea. The apical 
of the club of Its antenna, moreover, is (though not ^oider) relatively more b 
than m cZeZ.^a therein approaching E. cestiva, from which its broader and fl. 
bmld, sexual character, less dull appearance, and the broader lateral margins o 
thorax abundantly distinguish it. 
Erichson (Ins. Deutschl., iii, p. 152) says E. silacea is moderately thickly 
finely punctured, and uses a corresponding phrase for E. deleta; but 
crelerr^me ' and "s^^UUssime" of Gyllenhal and Thomson appear to me the . 
correct expressions. 
Of the 24 recorded European species of this difficult genus (terminalis, Ma 
from Eussia, and ruUginosa, Heer, from Switzerland, not practically entering 
the account, as they appear to be unknown, except as descriptions) we now pi 
18, 1 thmk correctly named and distinct, the only one at aU likely to sink eventu 
b ing d^.s., Bns., as possibly a depauperized form of lO-guttata; and most, if 
all of the remamang six may be expected to occur in this country. One of th 
mdeed, VIZ., E ,y,m.a, Gyll., has already been reputed as Britil in the 2nd 
of De Marseul's Catalogue, probably from that species being included in Steph. 
K.Hva But there is another and more credible British reference in Hardy ; 
Bold s Catalogue of the Col. of North, and Durham, where (p. 46) it is state
