 Vale de Chiriqui, Panama. On elytra. 



Laboulbenia constricta nov. sp. 



Perithecium more than one half free, short, stout, inflated, somewhat 

 olive-brown, the tip not differentiated, one of the lip-edges becoming modi- 

 fied to form a rlattish or roundish brown prominence which lies usually 

 in a median position between two rather ill defined prominences on either 

 side of it. Receptacle usually with a double curvature, its basal cell very 

 large, somewhat inflated distally, the base and posterior margin paler, cell 

 II shorter, suffused below, strongly constricted distally, the constricted 

 portion paler or hyaline : the distal portion of the receptacle short, 

 deeply suffused, bulging strongly anteriorly below the insertion of the 

 appendages. Insertion-cell not blackened, the appendages arising much 

 as in L. Orectochlli and L. strangulata, the branches hyaline, the basal 

 portion closely septate, simple, without persistent blackened basal por- 

 tions. Spores 70 X 6^. Perithecia, average 130 X 60 /x. Total length 

 to tip of perithecium, average 400 /.t ; to insertion-cell 340 p. Appendages 

 70 /x (or more ?).

 Egypt. On elytra. 



Laboulbenia Copteae nov. sp. 



Very slender. Perithecium free except the base, nearly straight, 

 curved outward slightly at the tip, which is blackish with hyaline lip- 

 edges ; dull translucent olive-brown, concolorous with the receptacle, or 

 with the basal wall-cells nearly hyaline. Receptacle slender, bulging 

 slightly at the base of the perithecium, cell II narrower distally than cell 

 I, the base of which is hyaline. Outer appendage consisting of a basal 

 cell several times as Long as broad, hyaline, usually curved strongly 

 outward, constricted distally where the septum is suffused with dark 

 brown below the single straight branch, which is more slender, elongate, 

 tapering, hyaline, simple or once branched above its basal cell. Inner 

 appendage consisting of a small basal cell bearing a short branch on 

 either side, simple or once branched, usually not longer than the perithe- 

 cium. Perithecium 120-140 X 35 u. Total length to tip of perithecium 

 340-470^; to insertion-cell 220-300 p. Appendages (longest) 400^.
