the regularly curved basal margin in an obtuse angle on each 
side. The very short elytra are shining, like the pronotum, 
and show traces of fine strize but no punctures. ‘The 
pygidium is smooth but fora few scattered punctures. The 
front femora are almost like those of the male Pachylomera 
femoralis, having a tooth near the base connected by a 
serrated carina with one of the two sharp teeth situated near 
the articulation with the tibia, and the coxa is also toothed 
in front. The great broad front tibia is armed with four 
teeth along the anterior half of the outer edge, the inner edge 
is serrated and above it is an upturned fringe of short hairs, 
while the upper face has also two small brushes of similar 
hairs upon its anterior half. The middle and hind tibiz each 
bear a blunt spatulate terminal spur, extending beyond the 
tarsus in the middle legs, but only half its length in the hind 
ones. The hind tibia has two parallel fringes of stiff hairs 
directed upwards, the inner one continuous and the outer 
interrupted. Both pairs of tarsi are rather broad and the 
claws are minute, short, straight, and not divergent,

GEOLOGICAL SOCIETY, 
December 4th, 1918.—Mr.G. W. Lamplugh, F.R.S., 
President, in the Chair. 
The following communication was read :— 
‘The Carboniferous Succession of the Clitheroe Province.’ By 
Lt.-Col. Wheelton Hind, M.D., B.S., F.R.C.S., F.G.S.; and 
Albert Wilmore, D.Sc., F.G.S. 
The tectonic structure of the province consists of three dissected 
parallel anticlinal folds in beds of Carboniferous-Limestone, Pendle- 
side, and Millstone-Grit age. The general direction of the axes of 
these folds is east-north-east and west-south-west. Dissection has 
exposed the lower beds of Z, C, and S age, as the tectonic axes and 
beds of D, P, and Millstone-Grit age occur on the flanks. 
The Limestone sequence shows all the zones from Z to D, 
Modiola and Cleistopora phases have not been exposed, the base 
of the Carboniferous not being seen. The Z beds are much thick- 
ened, and not so fossiliferous as in the Bristol Province. Cand S 
beds are, as a rule, well-bedded, with shales intercalated between 
beds of limestone. There are crinoidal beds of considerable thick- 
ness in places, and shell-breccias are common in 8S. Zaphrentis 
omalius? indicates an important horizon in Lower C, and these
