328 WOXOGRAPH OF THE LABOULBENIACE^. 
Laboulbenia pilifeea Thaxter. Plate XIV, figs. 19-22.

Pcrlthecinm tinged with olive-brown, the apex deeply blackened, broad, more or less evenly 
rounded, or nearly truncate, often symmetrical. Appendages consisting of two basal cells, the 
inner minute, the outer large, usually followed by a sub-basal cell, from which arise two very 
elongate, simple, erect, rather closely septate branches, at first dark brown above their nearly 
hyaline basal cells. The inner appendage consists of two short, hyaline, fertile branches, one 
of which may produce a long and sterile branch. Receptacle short, about equalling the pcri- 
thucium in length, the anterior margin rather abruptly diverging above cell II. Spores, about 
60x4/i. Perithecia, average, 25x90)U. Appendages, longest, 550 /^. Total leugth to tip of 
pcrithccium, 150-190 /i. 
On Anisoclactylus Harrisii Lee., J., nigerrimus Dej., A. intcrpunctatus Kirby, Ilarpalus plcuri- 
ticus Kirby, and H. erythropus Dej., Maine, Massachusetts, Pennsylvania. 
A common species found usually densely crowded along the outer margin of the elytra 
towards their base, less frequently elsewhere. The very long outer appendage is usually broken 
off in part. The two specimens figured are type forms, but the tip of the pcrithccium is not in 
all cases so abruptly truncate, and the lip-cells are sometimes distinctly turned outward with a 
sub- hyaline area about the lateral pore. Tlie hosts are common everywhere about ponds and in 
fields.

outwardly oblique apex, which is blackened below the hyaline lips. Appendages arising from an 
outer and an inner basal cell, the outer of which is followed by a squarish cell of about the same 
size, from the end of which project four rather short, rigid, slightly divergent hyaline branches, 
which taper to blunt tips, and, as a rule, hardly exceed the tip of the pcrithccium : the inner 
basal cell gives rise to two squarish cells, one on either side, each of which bears usually a pair 
of branches similar to those just described. Receptacle short and stout, normal in form, the 
lower portion o the basal cell hyahne. Perithecia, 55x18/.. Appendages Gongest), 65^.

The occurrence of a most typical and decidedly insignificant looking species of this genus on 
a larva of the worker of a species of white ant is certainly quite unexpected in view of the 
wide difference which exists between this neuropterous host and the usual insects infested 
by he genus. But for the four stiff branches arising from the sub-basal cell of the outer 
appendage, and suggcstmg the roots of a molar tooth, it would be ditTicult to specify its dis-
