granulated, and the fact that the episterna of the metasternum are 
elongate-linear, and not triangular. 
I. Upper surface with the pubescence forming spots and bands ; 
antenne less distinctly serrate from fifth joint; tarsal claws 
serrate and armed with a slender tooth almost reaching apex . M. rascrATa, F. 
Il. Upper surface with even pubescence ; antenne more distinctly 
serrate from fifth joint ; tarsal claws not distinctly toothed. . M. AcuLEATA, L. 
M. fasciata, F. Black, with the suture and a variable band 
before and behind middle of elytra thickly pubescent, the pubescence 
being grey or yellowish-grey ; sometimes the front band takes the 
form of an oblique patch at each shoulder; antenne dark with base 
red, longer and stouter than in Zomovxia ,; thorax transverse with the 
borders clothed with grey pubescence, strongly bisinuate at base, very 
finely sculptured; scutellum almost semicircular; elytra gradually 
narrowed from apex to base, separately rounded obtusely at apex, 
very closely sculptured; anal process long and pointed; legs black, 
_ posterior spurs ferruginous. L. 5-7 mm. 
Male narrower than female, with the pygidium and anal style more 
elongate. 
On flowers of Umbellifere —in woods, &c.; it passes its earlier stages under bark 
and in rotten wood ; very local, but occasionally found in abundance; Mickleham, 
Maidstone, Bearsted ; Sittingbourne, Strood, Chatham ; Canterbury ; Dover; Abbots 
Wood; Hastings; Lewes; New Forest; Exeter; Swansea; Monks Wood, Cam- 
bridgeshire, 
M. aculeata, L. Black, clothed with fuseous or fuscous-grey 
pubescence, which is unicolorous on the upper side; the metathorax and 
base of the segments of the abdomen are usually silvery white ; punctua- 
tion close ; antenne black, lighter at base ; thorax much broader than 
long; elytra at base slightly narrower than base of thorax, gradually 
narrowed behind, obtusely rounded separately at apex ; anal spine very 
long; legs black, anterior femora often testaceous. L. 4-6 mm. 
On flowers ; rare; Ripley, Surrey (Stephens) (Mr. Champion thinks this may be 
in error); Westerham, Kent, frequent (Gorham) ; Glanvilles Wootton, of occasional 
occurrence on guelder roses in May and June (Dale); Stephens also records it from 
Hertford, Monks Wood, near Swansea (common), and Scotland; the species is 
common in France, and appears to be very variable to judge by the number of named 
varieties ; the same may be said of M. fasciata. 
NMORDELLISTENA, Costa. 
This genus is also an extensive one, containing more than a hundred 
species, about one-third of which are found in Europe; the remaining 
species, however, with the exception of half-a-dozen or so from Chili and 
Ceylon, appear to be chiefly confined to North America ; the distribution 
of the genus is therefore very different to that of Mordella; it is very 
closely allied to the latter genus, under which the distinctions between 
them have already been alluded to; the sub-genera Mordellochroa,
