MONOGRAPH OF TUE LABOrLBENlACE.T!. 3C5 
A specimen of this host bearing the parasite in consitlorable ninnhers on Ujc under side of ita 
abdomen was found in the ficcontc cuUection of ColcopterR. The fungus under a hand lens 
looks like a stifT slender bristle, and miglii readily bo ovtMlooked even wlion present in consider- 
able numbers. The materialj though abundant, coutainod no very young individuals^ so that the 
early development is unknown.

Receptacle consisting of two superposed cells, the upper bearing the appendage late 
the stalk-cell of the perithecium terminnlly. Pcrithccium asymmetrical, each series of 
composed of five cells; the apex somewhat pointed, the stalk-cell free. Appendage consisting 
of a basal cell bearing a series of superposed cells, each of which gives rise from its inner upper 
angle to a single short septate simple antheridial branch. S])ores oncc-scplale. Ascogcnic cell 
solitary. 
This somewhat insignificant genus is perhaps related to Compsomycca,'ns may be indicated 
by the structure of its perithecium, the wall-cells of which are unusually numcroufl. The 
peculiar disposition of the cannl cells near the ti]) has bcon already referred fo (]», 2ol). The 
trichogyne lias been observed in a single specimen only, wliich was bndly broken. It appoare to bo 
filamentous and branclied. Owing to its rarity the early stages have not boon observed. In a 
single young specinicn of S. Latlirohii (Plate XI, fig. 10) a perfect nppendage was obtained, 
showing the sub-terminal origin of the flask-shaped antlieridia, and the presence of a peculiar 
spine at the base of the sub-terminal cell, to which reference has been made above (p. 2*^0), 
Although marked by no great peculiarities, the generic tyj>e is clearly defined by the two very 
distinct species.

Proc Am. AcaJ. Arts auJ Sci. Vol. XXIX, p. 95, 
Wholly hyaline or faintly yellowish, Perithecium ratlier slender, slightly inflated toward 
the base, tapering to the somewhat pointed apex which is bent inward; the dividing lines 
between the wall-cells indicated by successive ridges, the distal more prominent; the stalk-cell 
short, the basal cells rather large. Receptacle consisting of two obliquely superposed cells, the 
upper bearing the stalk-cell of the perithecium distally and the basal cell of the appendage 
laterally. Appendage borne on a large basal cell connected on its inner side with the distal cell 
of the receptacle and a portion of the stalk-cell of the perithecium, its exterior wall usually mucli 
thickened so as to form a more or less distinct rounded prominence at the base of the appendage 
proper, which consists of a series of four or five obliquely superposed cells diminishing in size 
towards its apex, from each of which arises on the inner side a single branch; the branches 
directed obliquely upward and forming a single series, septate, cylindrical, simple or bearing 
near their tips single short flask-shaped anthcridia. Spores, 35 x 3-3.5 ;x. Peritbocia, 100 x 22 /x-

of appendage, 110-106 /x. Ptcceptacle, 38-15 fx long.
