 Borneo No. 299, Sumatra. At base of anterior legs. 



Laboulbenia Taenodemse nov. sp. 



Perithecium nearly free, slightly inflated, clear translucent brown;

 Insertion-cell large, free, blackish, hardly narrower than cells IV and 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 branclilets curving upward : the inner appendage con- 

 sistins: of a much smaller basal cell, rounded and bearing; one or two short 

 branchlets. Spores about 70 X b jx. Perithecia 12.5-155 X 35-50 /x. 

 Total length to tip of perithecium 400-650 jx ; to insertion-cell 300-

 as in L. plat>/stoma, the basal cell of the outer appendage blackened 

 externally, all the branches erect and lying across the tip of the perithe- 

 cium which is bent toward them. The material on Cdtoscopus much 

 larger and darker than tliat on Mlscelus. Perithecia 90-130 X 22-26 u. 

 Total length to tip of perithecium 250-500 /^ ; to insertion-cell 425-185^. 

 Greatest width 37-55 /a. Appendages more than 200 ^ (broken).
