the insertion-cell bearing a single branch of usually three cells more or 

 less deeply tinged with brown, each of which may give rise distally on 

 the inner side to a short simple branchlet ; the inner appendage consists 

 of a basal cell shorter and broader, which usually bears distally on either 

 side a branch, the basal cell of which usually bears distally two erect 

 simple branchlets, one of them sometimes replaced by a single large 

 long-necked brown antheridium. Perithecia, including the stalk {17 fi), 

 150-155 X 30 fi. Total length to tip of perithecium 290-310 fx ; to inser- 

 tion-cell 150^; greatest width 35 /x. Appendages, longer 200 /x.

Laboulbenia Ceylonensis nov. sp. 



Perithecium wholly free, suffused with smoky brown, relatively short 

 and small, straight, slightly inflated, somewhat abruptly contracted distally 

 to form the unusually large broad tip, the distal half of which is hyaline, 

 distinguished from the opaque black lower half by a clean cut line of 

 demarcation : the basal cells forming a short stout hyaline neck narrower 

 than the body of the perithecium. Receptacle elongate, of nearly the 

 same diameter throughout, the basal cell nearly hyaline, the cells above 

 it more or less deeply suffused with smoky brown, cell V and the upjier 

 portion of cells IV and VII hyaline, the distal suffused portion obscurely 

 punctate. Outer appendage consisting of a basal cell deeply blackened 

 externally (the blackened area continuous with the black insertion-cell 

 and involving also the external walls of the two cells immediately above 

 it) producing from one to three branches arranged antero-posteriorly, 

 which may be once or twice branched in a similar fashion, the branchlets 

 long, slender, drooping, hyaline, some of the lower cells suffused with red- 

 dish brown : the inner appendage consisting of a basal cell about half as 

 large as that of the outer, producing in the types a single branch which 

 may be once branched as in the outer. Perithecium 105 X 32 ^w. Total 

 length to tip of perithecium 445 ^ci ; to insertion-cell 320 ^m. Greatest 

 breadth 42^0. Appendages 340 /<. 



On Hexagonia? , Ceylon, Hope Coll. No. 288. On elytra. 



Laboulbenia Chiriquensis nov. sp. 

 Perithecium yellowish brown, straight, the inner margin convex, the 

 outer slightly concave, tapering distally to the broad short blackened tip,
