main bod) ; the cell rows consisting of but five cells, including the very small lip-cells, and the cells of the 
sterile ha ; the three uppei tiera of cells forming an abruptly differentiated, thick walled, long, tapering 
beak-like termination, curved outward or inward, often at right angles; below which the distal end of the 
outer wall-cell forms a slight rounded prominence, the very small lip-cells forming a slight enlargement. 
Appendage similar to and continuing the axis of the receptacle directly, or diverging very slightly; the 
cells giving rise to a double series of branches, which are subtended by small cells obliquely separated at 
the distal angles, those from tin- lower cells short (antheridial ?), those from the upper long and several 
tim. branched; the main appendage usually broken, but in young individuals consisting of from twenty 
to twenty-five superposed cells. Spores 48 X 3 /*. Perithecia, ascigerous portion 175 X 45-50 ft, beak- 
like termination 140-160 ft, sterile basal portion about 100 ft. Receptacle 270-430 X 30-35 ft. Ap-

Although but a small percentage of individuals of this host were found to be infested, abundant 
material was obtained, the beetles occurring in large numbers on the under side of pieces of board floating 
along the margin of Lake Eustis. In two individuals the parasite was attached to the inner surface of 
the elytron near its tip, all the individuals being remarkable for the monstrous development of the peri- 
theciiiin which i iched a maximum length of one millimeter. It is possible that the following species 
may also be a similar variation due to its position of growth. Although the branches of the appendage 
are originally opposite in two rows, the latter become as a rule approximated on the inner side, as a result 
of greater external growth in the cells of the main axis.

Hyaline with a few purplish or reddish suffusions on the receptacle, which is composed of from about 
twenty-five to fifty superposed cells with occasional longitudinal septa; the foot hyaline, or slightly yellow- 
ish, much enlarged, bladder-like or spherical; the distal portion distinctly broader, its axis coincident 
with that of the erect appendage which forms a direct continuation of it. Perithecium small with few 
sari, abruptly recurved at the base, its apex thus sometimes touching the inflated foot; nearly straight, 
tapering almost symmetrically to the blunt slender tip; the ascigerous cells situated at the base just above 
the small angular stalk-cell. Appendage usually flat and broader than the receptacle toward its base, 
the superposed flat cells of which it is composed producing appendages on either side much as in C. rhyn-

Specimens of this species were found on several individuals, but never fully matured, growing on the 
soft integument of the upper surface of the abdomen just beneath the elytra, from under which they may 
be seen projecting. The branches of the primary appendage remain opposite and the basal cell of the
