166 PROCEEDINGS OP THE AMERICAN ACADEMY. 



slightly inward and abruptly differentiated, the lips well defined. Recejv 

 tacle dirty brown finely and obscurely punctate, of the typical form, lighter 

 below, short, stout, cell I much narrowed below, cell II very broad, slightly 

 inflated. Basal cells of appendages well developed bearing about eight 

 erect short stout simple branches with broad basal constricted blackened 

 septa, their rounded tips slightly exceeding the tip of the perithecium. 

 Spores 70x7;u. Perithecia 140-170 X 62^11. Total length to tip of 

 perithecium 325-400 ^u; to insertion-cell 250-300^; greatest width 

 100 /i.

 Bengal, India. Along median depression of elytra. 



Laboulbenia Colpodis nov. sp. 



Perithecium wholly free, very large, uniform clear translucent brown, 

 slightly inflated or the margins straight, the basal wall-cells forming a 

 well marked hyaline neck as broad as the base of the ascigerous portion 

 from which it is not abruptly distinguished ; the tip rather narrow and 

 well distinguished, darker, the distinct lip-edges hyaline or translucent. 

 Receptacle very small, cell I hyaline or yellowish, the rest more or less 

 deeply suffused with blackish brown becoming nearly opaque, especially 

 cells III and IV, which lie side by side and are about equal in size, cell 

 III forming a rounded jirominence just below the outer edge of the inser- 

 tion-cell, cell V triangular, about as large as cells III and V combined. 

 Insertion-cell not at first deeply blackened, but becoming indistinguishable 

 in the general blackish brown suffusion of the adjacent cells. Outer ap- 

 pendage consisting of a nearly erect series of obliquely superposed small 

 cells (sometimes as many as thirteen) at first hyaline, the basal cell and 

 sometimes several of the cells above it becoming deeply suffused, which 

 produce externally a single simple branch curved upward, its basal por- 

 tion consisting of two cells, sometimes three, longer than broad and 

 more or less deeply suffused with brown, constricted at the dark 

 septa ; its distal portion elongate, reaching nearly to the tip of the peri- 

 thecium, strongly tapering hyaline except at its base where it is in- 

 volved by the brown suffusion of the basal part ; the inner appendage 

 consisting of a basal cell surmounted on either side by a series of cells 

 similar to that of the outer appendage, but fewer in number, similarly 

 branched except that the two or three lowest cells of each series bear 

 single large stout straight brown antheridia, the basal cells of the series, 

 as in the outer appendage, becoming suffused with blackish brown. Peri- 

 thecia 190-220x40-45^. Total length to tip of perithecium 300-
