THAXTER. — NEW LABOULBENIACEiE. 203 



often divergent, deep brown, the suffusion involving the basal cell which 

 bears it : each branch consists of a single simple cylindrical cell the distal 

 portion of which is usually broken off leaving the deep brown contrast- 

 ing base. Spores 60 X 4.5 /x.. Periihecium 120-140 X 40-45 ^u ; to 

 insertion-cell, average 275^. Appendages 100 /x. 



On Orectochilus ?, Brit. Mus. Nos. 480 and 484, Timor, East Indies. 

 Margin of elytra. 



Labotilbenia subconstricta nov. sp. 



Perithecium less than one half free, rather small, curved strongly and 

 evenly toward the appendages, evenly suffused with dark brown or lighter 

 distally; the tip black, not abruptly distinguished, the lips distinct with a 

 broad hyaline margin about the pore. Receptacle dull amber-yellow, 

 cells IV and V, sometimes cell III, less deeply suffused with brown; 

 cell I narrow, straight, but slightly enlarged distally; cell II abruptly 

 much larger, symmetrically and prominently constricted in the middle ; 

 cells III and IV large and broad. Outer appendage simple, the basal 

 cell moderately large ; externally or wholly blackened ; the rest of the 

 appendage straight, rigid, directed across the tip of the perithecium : 

 inner appendage consisting of a smaller basal cell which bears one or two 

 branches similar to the outer appendage. Perithecia 85 X 25 ^. Total 

 length to tip of perithecium about 200 /a ; to insertion-cell 165 /x ; greatest 

 width 50 jtt. Appendages, broken, about 150 ^u or a little more. 



On Catoscopus sp., Paris Museum, No. 116, New Guinea. On anterior 

 inferior margin of thorax on the rioht side. 



Laboulbenia Sumatrae nov. sp. 



Perithecium small, pale amber-colored, darker and somewhat inflated 

 below, tapering distally ; the tip only free from the receptacle not distin- 

 guished from the body of the perithecium, long, nearly hyaline below, 

 the lip-cells abruptly spreading, contrasting, black except about the pore 

 and peculiarly modified, the two outer broadly rounded, the two inner 

 developing outgrowths which grow inward and upward ; that on the 

 right side longer than the left, narrower and indented near the base on 

 the inner side. Receptacle ooncolorous with the perithecium, paler 

 below, marked by faint fine tranverse striations. Appendages concolor- 

 ous with the receptacle, the outer simple, stiff, curved slightly outward, 

 the inner consisting of a basal cell smaller than that of the outer and 

 bearing ou either side a branch which may be once branched at the base.
