About one hundred and twenty species are comprised in this genus; 
they are chiefly found in tropical countries, only two oceurring in 
Eurepe, ef which one is rather common in Britain. 
The larva of L. murinus is figured by Schiodte (Part v. pl. vi. fig. 2); it is 
elongate and parallel-sided, of a pale yellowish colour, with the sides white and the 
head, prothoracic scutum, and the ninth segment of abdomen fusco-ferruginous ; the 
prothorax is much longer than the meso- and metathorax, and the third abdominal 
segment is longer than the others; the sides of head and body are furnished with 
long hairs; the last segment cf the abdomen is nearly as broad as the preceding, 
serrate at the sides and terminated by two strong bifid points which represent the 
cerci; the legs are visible from above. 
GZ. murinus, [.. A rather large broad species, black or dark 
brown, thickly clothed with light and ‘dark brown and ereyish tomentose 
pubescence, which gives the. upper surface a variegated appearance ; 
head rather convex, punctured, antenne rather short, entirely received 
in grooves beneath, yellow with the first joint black; thorax a little 
longer than broad, convex in centre and depressed and uneven towards 
base, with the poster or angles very blunt and truncate, upper surface 
distinctly and closely punctured on disc, more closely at sides; scu- 
tellum large; elytra much depressed at ‘base, gradually narrowed to 
apex, broadest in or about middle, with very feeble and feebly punctured 
striz, interstices finely punctured ; legs pitchy or pitchy red, knees and 
tarsi light red. L. 9-14 mm. 
Grassy places by sweeping ; occasionally in moss, garden refuse, &c.; often on the 
wing; common and generally distributed in the London, Southern, and Midland 
districts ; tess common further north; Snewdon; York ; Manchester ; Northumber- 
land and Durham district; Scotland, scarce, Lowlands, Tay district ; Ireland, near 
Dublin, local; Furnish Island (co. Galway).

More than two hundred species are known as belonging to this genus, 
of which fifty are found in Europe ; the rest are very widely dis- 
tributed, and range frorn Siberia to Madagascar and the Cape of Good 
Hope, although the majority appear to be found in temperate countries; 
the genus is distinguished by its very convex thorax, the comparatively 
short posterior angles of the same, and the cordate scutellum ; the
