or the inner once branched above its subbasal cell ; the antheridia borne 

 singly at the lower septa or on short branchlets : all the branches of 

 both appendages relatively stout, erect, rather closely septate, about 

 six- to eight-celled, curved slightly outward, tapering to the blunt ex- 

 tremities, which but slightly exceed the apex of the perithecium. Spores 

 55 X 5 jU. Perithecia 165-185 X 55-65 ^t. Receptacle 220-325 X 75 ^. 

 Longer appendages 220 /x. Total length to tip of perithecium 440-500 ^u. 

 On the abdomen of Philonthus poUtus Linn., Alverstoke, England; 

 British Museum, No. 363. A form which is doubtfully separated from 

 the almost endless variations of the L. Jlagellata type and which, though 

 sufficiently well marked in the type material, may prove a mere variety. 

 No other closely allied form, however, is known to occur on species of 

 Philonthus. 



Laboulbenia Euchilae nov. sp. 



Slender, nearly uniform pale dirty yellowish throughout. Perithecium 

 relatively small with a faint brownish tinge, about four fifths free, erect, 

 straight ; the tip fairly well distinguished, the inner lip-cells large, promi- 

 nent, rounded, the lip-edges outwardly oblique. Receptacle slender and 

 long, punctate ; the subbasal cell much longer than the basal, nearly 

 isodiametric, or swollen above the basal cell and broader than the distal 

 part of the receptacle, which is separated from its distal end by a promi- 

 nent constriction ; cells III and VI subequal, or cell III larger ; cell V 

 very small ; cell IV longer than broad, becoming externally tinged with 

 brownish. Insertion-cell relatively thick, free, narrow. Appendages 

 becoming wholly dark brown, in contrast to the rest of the plant ; the 

 outer simple or once furcate above the third cell ; the basal cell more 

 than twice as long as broad ; the basal cell of the inner appendage less 

 than one half as large as that of the outer, bearing a usually simple 

 branch on either side, which bears single antheridia near its base. 

 Spores 60 X 4.5;u. Perithecia 100x30/^. Receptacle 220-250 X 

 35-40/7. Appendages 150 |U. Total length to tip of perithecium 

 300-350 ^. 



At the base of the anterior legs of Euchila flavilahris Dej., Brazil ; 

 Berlin Museum, No. 938. 



Laboulbenia Eudaliae nov. sp. 



Perithecium transparent brown, nearly straight externally, the inner 

 margin somewhat convex ; the inner lip-cells deeply suifused, contrasting, 

 coarse, erect, prominent, the lip edges hyaline, outwardly oblique. Re-
