blunt hyaline papilla, turned outward and hardly distinguished from the 

 body of the perithecium, and wholly subtended by a wide blackish suffu- 

 sion, the outer margin forming a slight curvature continuous with that of 

 the receptacle. Receptacle relatively small, the basal cell small, narrow, 

 and quite hyaline, except distally, where it is partly involved in the dark 

 olive-brown suffusion of the rest of the receptacle, which is coarsely 

 punctate in the region of cells If and III, becoming wholly opaque and 

 indistinguishable from the base of the perithecium, with the exception 

 of cell V and a corresponding cell of about equal size which lies external 

 to it, being cut off distally from cell IV, the receptacle being abnormal in 

 this respect. These two cells hyaline or translucent, the whole anterior 

 margin, from the base of cell II to the tip of the perithecium, forming 

 a nearly symmetrical continuous curvature. Outer appendage consisting 

 of a small slightly prominent basal cell, slightly coustricted above, where 

 it is separated by a blackish septum from a hyaline erect slender nearly 

 straight distal portion or branch : the basal cell of the inner appendage 

 somewhat smaller, giving rise to several erect branches, like the outer, which 

 reach about to the tip of the perithecium, or may be longer. Perithecia 

 80-100 X 32-40//. Receptacle 90 p. Appendages 75-110//. Total 

 length to tip of perithecium 185-220 X 40-48//. 



On legs and on the inferior surface of the abdomen of Lebia sp., Java; 

 Rouyer, No. 1396. Closely resembling L. curtipes in general form. 



Laboulbenia pusilla nov. sp. 



Short, stout, pale yellowish. Perithecium free, straight, very slightly 

 narrower distally, the distal portion, except externally, about the hyaline 

 pore, deep black, the suffusion extending less than half-way down exter- 

 nally, and about a third on the inner side : the distal end broad, flat, 

 projecting on the inner side to form a rounded prominence; the pore 

 lateral and external, hyaline, with adjacent paler shades; the black, 

 slightly projecting area below it forming a more or less clean-cut line of 

 demarcation. The receptacle short and stout ; cells I and II subequal, as 

 are also cells III and IV. Appendages as in L. orientalis, hyaline, the 

 two basal cells partly overlapping and bearing each four to five branches 

 four to five times branched, the cells distinguished by constrictions and 

 blackish septa. Spores 45 x 5 //. Perithecia 90 X 36-40 //. Receptacle 

 100-110//. Total length to tip of perithecium 200 X 210//. Append- 

 ages 100-110//.
