predominate. The broad raised margin of the pronotum 

 indicates its relationship to the present family, and there 

 is also a pecuhar stnicture, not hitherto noticed, on each 

 side of the base of the pronotum, which may be homologous 

 with the basal fovea so characteristic of the Endomychidae. 

 Only a single specimen, now in the Genoa Museum, has 

 been previously known, l)ut a second species, of which 

 there are two specimens in the British Museum, is now 

 described .

I know the typical species of the genus {M. decempmictata) 

 only from the published figure and description, but, 

 although evidently related closely, it is very different 

 in pattern and apparently more elongate in shape and 

 more sparsely clothed wath hair. M. fasciaUi is very 

 broadly oval and highly convex and is entirely clothed 

 with short erect grey pubescence. The head, lower 

 surface, antennae and legs are red, with the large 

 round club- joint of the antenna and the sides of the 

 head darker. The pronotum and elytra are black, with 

 the sides of the former red (except the extreme edges 

 and sometimes the hind angles) and an arrowhead-shaped 

 median stripe not quite reaching the base, an undulating 

 transverse band upon the elytra just beyond the base, 

 sometimes with an anterior offshoot cutting off the 

 humeral callus, a similar band a little beyond the 

 middle, sometimes interrupted at the suture, and an 

 obhque mark on each side between the last and the apices, 

 reaching the outer margins but not the suture, are also red. 

 The upper surface is shallowly and irregularly, but rather
