inferior margin of the thorax and tlie adjacent posterior margin of the prothorax. It is subject 
to but slight variation, and is doubtless widely distributed.

Iljalino, becoming tinged with brown. Ferithecium more or less inflated, narrowed towards 
the broad, blunt, often symmetrically rounded apex, becoming more or less suffused with brown, 
projecting outward from the receptacle. Outer appendage simple, taperiiig, its base made up of 
three short, superposed, conspicuously inflated cells constricted at the blackened sci)ta, the distal 
portion more remotely septate, not inflated or constricted ; the inner appendage rises from a 
basal cell, nearly as large as that of the outer, which gives rise to two simple, hardly divergent 
branches, one to three of the basal cells of which arc inflated as in the outer appendages. 
Receptacle normal. Spores, 50 x 4.5 /z. Perithecia, average, 90 X 37 ^ (largest, llOx 50;^). 
Appendages, longest, 185 /*. Total length to tip of perithccium, 150-200 /*.

This very pretty and well marked species appears to be not uncommon on the above men- 
tioned host, which is probably identical with the beetle on which the original types were found ; 
although this was, by an oversight, stated to be a species of P.ombidium. It is distinct from all 
other species in the character of its appendages, and could not be mistaken for any described

Pale yellowish. Perithecium becoming tinged with olive-brown, inflated, the lip cells com- 
pressed to form an evenly rounded, narrow, prominent apex, which is commonly bent sliglitly 
outward, and blackish brown except about the pore, winch is external and lateral. Outer 
appendages simple or once branched above its sub-basal cell, the lower cells slightly inflated, the 
branches straight and tapering. From the inner basal cell arise two branches, which may be 
simple or once branched, the sterile branches like the outer appendage. Receptacle normal, the 
basal cell usually curved. Spores, 60 X 3.7-4 /z. Perithecia, 85-100x30/.. Appendages, 
longest, 150-200 /x. Total length to tip of perithccium, 175-260 fi, average, 210 /*.

This small species in its typical form is hardly to be confused with any other by reason of 
its narrowly pointed perithecium ; but specimens are sometimes found which indicate that it is 
fiUf, 
It is almost 
invariably found at the base of the middle pair of legs of its host, usually at the right, rarely 
on the elytra, and is not very common. The spores are remarkably long and slender in pro- 
portion to the size of the perithccium. The hosts affected were found under stones about muddy 
ponds.
