54 PROCEEDINGS OP THE AMERICAN ACADEMY. 



cells II and III edged with blackish brown externally ; cell IV wholly 

 blackish brown ; cell V hyaline or partly suffused, the insertion-cell thick. 

 Basal cell of the outer appendage more or less suffused, giving rise to an 

 outer and an inner branch ; the basal cell of the former giving rise to an 

 outer, shorter, and an inner branchlet ; the inner branch simple : basal 

 cell of the inner appendage bearing a simple branch, distally furcate 

 above its basal cell ; the branchlets both fertile, short, with a single 

 terminal antheridium ; or one of them sterile and similar to the outer 

 appendage, short, stout, nearly straight, stiff, opaque, hyaline-tipped : 

 the antheridia relatively large, solitary ; the broad neck bent abruptly at 

 right angles. Perithecia 90-110 X 40-48 /a. Receptacle 220-25Q p. 

 Appendages 150-185 /x. 



On Metronemus caliginosus Blk., Oahu, Honolulu"; No. 1261 and 

 1262. Perkins Collection, Hawaiian Carabidae. Right inferior surface 

 of prothorax. 



Laboulbenia Stomonaxi nov. sp. 



Perithecium hyaline, becoming tinged with brown, less than one half 

 free ; short, the outer margin nearly straight, bending rather abruptly 

 inward at the tip ; the inner margin converging to the apex from its 

 point of union with cell V ; the tip rather abruptly distinguished, broad ; 

 the apex nearly flat, the lips hardly j:>romineut. Receptacle yellowish 

 or hyaline, with faint brownish shades ; the basal cell usually bent, the 

 subbasal with deeper brown suffusions ; cell III more or less deeply 

 suffused with brown, its thick outer wall opaque or nearly so ; cells III 

 and IV subequal, several times longer than broad ; cell V long-triangular. 

 Insertion-cell thick, black, contrasting, wholly free, separated from the 

 perithecium by nearly the whole upper margin of cell V. Outer append- 

 age curved strongly outward, hyaline on its inner side, deeply suffused 

 on the outer concave side, the suffusion continuous with the insertion- 

 cell ; consisting of a small number of cells, the basal relatively long, the 

 rest producing suberect hyaline branchlets distally on the upper side : 

 basal cell of the inner appendage smaller, the subbasal cell usually 

 bearing two branchlets (the appendages broken in the types). Spores 

 50 X 5 jx. Perithecia 65 X 25 fx. Receptacle 100-1 10 [x. Append- 

 ages 50-75 fi approximately. Total length to tip of perithecium 

 130-140.
