On Morio sp., Paris Museum, No. 112, New Guinea. On anterior 

 inferior surface of thorax on right side. 



Laboulbenia Pericalli nov. sp. 



Peritheciura becoming almost opaque, its upper fourth, sometimes only 

 the tip, free from the receptacle, relatively small, the tip more or less 

 prominent, sometimes subconical, short, and wholly black (often more 

 prominent, abruptly distinguished, the rounded lips well defined with 

 hyaline edges). Receptacle normal, cells III and IV large and broad, 

 concolorous with the peritliecium ; cells I and II together with the lower 

 end of cell VI pale yellowish. Outer appendage mostly simple, stout, 

 the lower cells slightly inflated ; inner appendage consisting of a much 

 smaller basal cell, bearing a usually simple branch on either side very 

 similar to the outer appendage ; all the branches yellowish or becoming 

 tinged with brown, especially toward the base. Perithecia 110-130 X 

 37-45 1.1. Total length to tip of perithecium 200-300 /x ; greatest breadth 

 about 75 fi. 



On Pericallus guttatus Chev., Paris Museum, No. 78, Java ; on Misce- 

 lus sp., Paris Museum, Nos. 113, 114, 115, New Guinea. 



Laboulbenia platystoma nov. sp. 



Perithecium free except at the very base, straight, rather long and 

 narrow, pale amber-yellow becoming slightly tinged with brown, slightly 

 and symmetrically inflated ; the tip black, opaque, the lip-cells forming 

 an abruptly spreading almost flat symmetrical termination with a slight 

 median indentation, two of the lips forming a small median hyaline 

 truncate cone, the other two arching over them from the outer and inner 

 side, wholly opaque except their inner margins, the blackened part not 

 quite meeting in the median line, the whole resembling the end of a 

 pair of horizontal cut plyers. Receptacle medium, pale amber-yellow 

 becoming tinged with brown distally. Outer appendage mostly simple, 

 the basal cell about twice as long as broad, often slightly inflated, the 

 rest of the appendage much narrower, straight, rigid, tinged with brown 

 tapering somewhat distally ; the inner appendage consisting of a basal 

 cell about half as long as that of the outer, producing a branch on either 

 side ; the branch usually bearing an antheridial branchlet near its base, 

 the branches and the outer appendage similar, often curved slightly out- 

 ward, becoming tinged with brown. Perithecia 175 X 40/i; the tip 37 /x 

 broad. Total length to tip of perithecium 325-400 /i; to insertion-cell 

 185-230 /Lt; greatest width 55-63 /^t. Appendages about llofi (longest).
