About one hundred and twenty species are comprised in this genus; 

 they are chiefly found in tropical countries, only two occurring in 

 Europe, of which one is rather common in Britain. 



The larva' of L. murinus is figured by Schiodte (Part v. pi. vi. fig. 2); it i 

 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-ferrnginous ; the 

 prothorax is much longer than tho meso- and metatbornx, and the third abdominal 

 segment is longer than the others ; the sides of head and body are furnished with 

 long hairs; the last segment of the abdomen is nearly as broad as the preceding, 

 serrate at the sides and terminated by two strong bifid points which represent the 

 i ; the legs are visible from above. 



Xi. murinus, I.. A rather large broad species, black or dark 

 br<>\vu, thickly clothed with light and dark brown and greyish tomentose 

 pubescence, which gives the upper surface a variegated appearance ; 

 head rather convex, punctured, antennae rather short, entirely received 

 in grooves beneath, yellow with th5 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 

 striae, 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, ic. ; often on the 

 wing; common and generally distributed in the London, Southern, and Midland 

 districts ; less common further north ; Snowdon ; York ; Manchester ; Northumber- 

 land and Durham district ; Scotland, scarce, Lowlands, Tuy district ; Ireland, near 

 Dublin, local ; Furnish Island (co. Gulway). 



CARDIOPHORUS, Eschscholtz. (Caloderus, Steph.) 



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 from Siberia to Madagascar and the Cape of Good 

 1 1< >!, although the majority appear to be found in temperate countries; 

 tin- genus is distinguished by its very convex thorax, the comparatively 

 .short posterior angles of the fame, and the cordate scutellum ; the
