Lnboulbenia Brachionychi nor. sp. 



Perithecium wholly free, rather deeply suffused with Bmokyor reddish 

 brown, subclavate or almost symmetrically inflated, tapering from the 

 middle t<> the oearly symmetrical, or externally Blightly oblique blunt 

 tip, the basal wall-cells contracted to form a long slender neck-like Bub- 

 li\ aline stalk. Receptacle abnormally developed, cells I and II nearly 

 equal, cells III and V forming a stalk whicb is deeply suffused with 

 blackish brown especially externally, and rather coarsely punctate in 

 the darker areas, of equal diameter throughout and quite free, except at 

 its very base, from the rest of the receptacle: cell IV larger than cell 

 III, cell V small and separated by an ohliipie septum : cell VII ami ill ■ 

 basal cells of the perithecium small. Outer appendage consisting "f a 

 basal cell deeply blackened externally, and bearing a long slender simple 

 branch, distally hyaline, more or less Buffused with Bmoky brown towards 

 the base : the inner appendage consisting of a basal cell about hah as 

 long as that of the outer, producing a single branch on either side which 

 ma\ be once or twice branched, the antheridia borne usually in twos or 

 threes on short branchlets near the base. Spore 110 X 7 fi. Perithecia 

 exclusive of stalk, 270-340 X 65 /j ; including stalk 340-430//. Total 

 length to tip of perithecium 650-800^; to insertion-cell 400-50<>u. 

 Stalkdike portion of receptacle 138 X 38//. Appendages 400— 470 //. 



On Brachionychw sp., Nos. 99 and «22, Cochin China ; on Epis- 

 cosoma laticoUis, No. 85, Cochin China; on Episcosoma sp.. No. 86, 

 Java. All in Paris Coll. Usually on inferior surface of thorax. 



Laboulbenia Cafii nov. sp. 



Perithecium almost wholly free, pale amber-colored or straw-yellow, 

 transparent, stout, the tip blunt, with blackish basal Suffusions, well dis- 

 tinguished, especially on the inner side. Receptacle short and stout, pale 

 amber-colored, normal in form. Insertion-cell broad, often not deeply 

 blackened. The appendages consisting of an outer and an inner Beries 

 of from four to six superposed cells which, through a twist of the insertion- 

 cell, become lateral instead of antero-posterior in position : each cell of 

 these series produces externally a single simple short branch usually 

 three-celled, the two lower cells short and inflated, the upper loug< r 

 tapering to a blunt apex. Perithecia 140- 165 X 60— 70 p. Total length 

 to tip of perithecium 310-350 fx, to insertion-cell about 170^. Append- 

 ages, lougest 85 p.
