146 SERRICORNIA. [ Malthinua. 
under-side yellow, breast and under-side of head blackish; legs long, 
clear yellow. L. 45-5} mm. 
Male with the head very strongly constricted behind, and the thorax 
yellow, immaculate. 
Female with the head moderately constricted behind, and the thorax 
yellow with dise dark, sometimes dark with margins narrowly yellow. 
By beating and sweeping in woods, &c.; on oak, hazel, hawthorn, and other trees 
and shrubs; generally distributed throughout the greater part of England and 
Wales, and in many districts, especially in the Midland counties, very common ; 
Scotland, not rare, Solway, Tweed, Clyde, Forth, and Moray districts; Ireland, near 
Belfast and Armagh, and probably common. 
M. fasciatus, Ol. Considerably smaller than the preceding, which 
it much resembles in general appearance; head and thorax rugosely 
punctured, the former large and much constricted behind, vertex 
narrowly dark, front broadly yellow; antenne comparatively short, not 
reaching apex of elytra, yellow at base, fuscous tewards apex; thorax 
about as long as broad, broadest just before middle, narrowed in front, 
with the posterior angles right angles; scutellum either fuscous or 
yellowish; elytra broader than thorax, of a light grey colour, with the 
base and a spot before apex, and sometimes suture, dark, apex sul- 
phureous yellow, punctured in rather strong and distinct rows; under- 
side and legs yellow, breast more or less infuscate. L. 3-8} mm. 
Male with the posterior tibiz furnished with a small tubercle on their 
inner side behind middle. 
By beating and sweeping in and near woods ; somewhat local but rather common 
in the London, Southern, and Midland districts of England. I do not, however, know 
of any localities in England further north than Hunstanton (Norfolk), Cannock 
Chase, and Glandovey near Barmouth. Ireland, Armagh (Johnson). 
IM. balteatus, Suffr. (fasciatus, var. b, Er.). Very closely allied to 
the preceding, of which it has been by some authors considered a 
variety or one of the sexes; in general appearance, however, it is very 
different, being much darker, with the head black with a yellow spot on 
forehead, and the elytra dark with a grey band about middle; the pos- 
terior legs also are fuscous; the general form is smaller and narrower, 
and the thorax is narrower and longer; the sculpture of the elytra is, 
perhaps, a little deeper. L. 3-3; mm. 
By beating and sweeping in or near woods; scarcer than the preceding species, 
but not uncommon in the London and Southern districts; it becomes rarer in the 
Midlands, and I know of no locality further north than Hunstanton, where I have 
taken it in company with M. fasciatus. 
M. frontalis, Marsh. This species is very easily known by its 
colour, which is unicolorous black, with the forehead yellow in the 
male and pitchy (almost unicolorous) in the female ; head rather large, 
dull, rugosely punctured, antenne fuscous with lighter base; thorax a 
little broader than long, with the sides almost straight, slightly narrowed
