28 PROCEEDINGS OP THE AMERICAN ACADEMY. 



what smaller than that of the outer, bearing a branch on either side 

 similar to the outer appendage, the three straight, closely applied in a 

 more or less compact group. Receptacle rather coarsely punctate, the 

 basal cell slender below and suffused above the foot, rather short, aud 

 separated from the usually very long subbasal cell by a more or less 

 distinct constriction ; cells III, IV and VI subequal, more than half the 

 upper margin of cell V free. Perithecia 100-125 X 35-40 /x. Recep- 

 tacle 220-275 x 45 /x. Appendages about 90 it. Total length to tip 

 of perithecium 290-360 ft. 



On elytra aud abdomen of Bledius jacobinus Lee, California ; Sharp 

 Collection, No. 1174. A short stout form which is perhaps a variety 

 of this species occurs on Bledius based is Lee. in Florida (Henshaw 

 Collection). 



Laboulbenia Borneensis nov. sp. 



General color pale dull straw yellow, transparent with brownish suf- 

 fusions. Perithecium about two thirds free, rather stout and relatively 

 small, externally convex, straight; a prominent hump, nearly horizontal 

 above and distally broadly edged with contrasting black, protruding 

 externally just below the narrow prominent abruptly differentiated tip, 

 which is bent strongly inward and is wholly deep black ; except the 

 coarse, contrasting, hyaline, outwardly oblique lip-cells, which, on the 

 inner side, are edged with black to the pore, the external black suffusion 

 of the tip continuous with that of the hump. Receptacle relatively 

 large, long and slender, the basal cell rather slender, hyaline below, 

 distally concolorous with the subbasal cell which is much longer, dis- 

 tinctly stained with smoky brown, and more or less distinctly ridged or 

 wrinkled ; cell III twice as long as cell IV ; cell V small, narrow, 

 triangular ; cell VI more than four fifths as long as cell V ; cell VII 

 roundish or squarish, and forming a rather abrupt external prominence 

 below the base of the perithecium. Appendages appressed against the 

 inner margin of the perithecium, the tip of which they hardly exceed: 

 the insertion-cell thick, black, well defined, not deeply constricted ; the 

 outer appendage apparently simple, the basal cell slightly longer than 

 broad, tinged with brownish ; the inner appendage consisting of a basal 

 cell almost similar to that of the outer, bearing two branches (possibly 

 only one) which are in turn several times branched. Spores about 

 45 X 4,u. Perithecia 100-125 x 35-50*4 (distally including hump 

 X 48 /.t). Receptacle 250-290x7. Appendages (broken) 90/*. Total 

 length to tip of perithecium 350-380 ft.
