Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 204. Dec, 1899. 
Perithecium nearly free, slightly inflate 1, clear translucent brown; the tip well differentiated, exter- 
nally black with an inner inferior hyaline patch, the lips well distinguished hyaline, the inner very promi- 
nent, rounded, the pore external. Receptacle long and slender through the elongation of cell II, pale 
dirty yellowish brown or nearly hyaline. Insertion-cell large, free, blackish, slightly narrower than cells 
IV + V. Appendages concolorous with the receptacle, the outer consisting of a large basal cell which 
bears distally as a rule two antero-posterior branches; the inner simple, the outer furcate above its basal 
cell; the branches stout, slightly tapering, elongate, the inner erect, the outer divergent; its branchlets 
curving upward: the inner appendage consisting of a much smaller basal cell, rounded and bearing one 
or two short branchlets. Spores about 70 X 5 /£. Perithecia 125-155 X 35-50 a. Total length to tip 
400 
Appendages, longest about 600 p..

be in 
; constant m their characters as represented in fig. 13. The peri- 
thecium is practically free and almost symmetrically inflated. The tip almost neck-like, the black and 
hyaline pans sharply contrasting. I was at first inclined to consider this one of the many varieties, per- 
haps better assembled under one name, which are included in L. flagel/ata and L. Pterostichi; but further 
comparison leads me to believe that it should be kept distinct. The hosts belong to a remarkable and very 
beautiful genus of large tree living Staphylinida? inhabiting tropical South America.

Pale yellowish, becoming tinged with pale reddish yellow. Perithecium more than one half free, 
relatively large, stout, nearly oblong, the black tip recurved externally through the rounded upgrowth 
of the inner distal portion of the perithecium which makes them almost lateral in position, the right lateral 
hp-cell often twice as long as the others and more prominently recurved, its projecting portion the branch- 
lets short, translucent, rounded. Receptacle medium, normal. Appendages normal, rather short, several 
times branched, the cells rather short stiff, divergent and somewhat tapering. Spores 50 X 3.5 p. Peri- 
thecium (not including lip-cells) 120 X 62 ft. Total length to tip of perithecium 100-120 ft; to insertion- 
cell J 2 ( .)2 /j. Appendages (longest) 40 u.
