granulated, and the fact that the episterna of the metasteruum are 

 elongate-linear, and not triangular. 



I. Upper surface with the pubescence forming spots and bands ; v 

 antenna; less distinctly serrate from fifth joint ; tarsal claws 



serrate and armed with a slender tooth almost reaching apex . M. FJSCIATA, F. 



II. Upper surface with even pubescence ; antennae more distinctly 



serrate from fifth joint ; tarsal claws not distinctly toothed . . M. ACTTLEATA, 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 ; antennae dark with base 

 red, longer and stouter than in Tomoxia ; thorax transverse with thu 

 borders clothed with grey pubescence, strongly bisiuuate 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 Umbellifereein woods, &c. ; it passes its earlier stages under bark 

 and in rotten wood ; very local, but occasionally found in abundance ; Hickleham, 

 ilaidstone, Beamed 1; Sittingbourne, Strood, Chatham ; Canterbury; Dover; Abbots 

 Wood ; Hastings ; Lewes ; New Forest ; Exeter; Swansea ; Monks Wood, Cam- 

 bridgeshire. 



Vt. aculeata, L. Black, clothed with fuscous 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 ; antennae 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, anteriur femora often testaceous. L. 4-6 mm. 



On flowers ; rare ; E'tpley, Surrey (Stephens) (Mr. Champion thinks this may be 

 in error) ; Westerham, Kent, frequent (Gorham) ; Glanvilles Wootton, of occasional 

 occurrence on gnelder 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. 



IVIORDELLISTENA, 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 MordeUocJiroa,
