34 PKOCEEDINGS OF THE AMERICAN ACADEMY. 



appendage somewhat smaller, bearing one or two hyaline branches 

 similar to those of the outer; on either side the external one is sub- 

 tended by a short stiff characteristically blackened branchlet: all the 

 branches stout, hyaline, elongate, tapering but slightly. Perithecium 

 nearly free, rich blackish brown, the suffusion involving part of its 

 basal cells; rather symmetrically inflated, a contrasting paler region 

 just below the well distinguished rather broad deeply suffused tip; 

 the lips rather coarse and prominent, the two inner lips bearing dis- 

 tally a well defined papilla. Perithecium 75 X 25 fi. Appendages 

 about 140 n. Receptacle 70-80 X 28 ju. Total length to tip of 

 perithecium 145 /x. 



On the tips of the elytra of Manobia abdominalis Jac, M. C. Z., 

 No. 2505. 



Although this species represents a somewhat ordinary type of the 

 genus, it differs from others that are known, through the presence of a 

 short black subulate branchlet which subtends the stout external 

 branch of the inner appendage on either side. The branches of the 

 appendage are unusually stout, almost hyaline, and diverge almost 

 horizontally in the two types, which are in good condition. 



Laboulbenia partita now sp. 



Receptacle very variably developed; elongate, or short and stout, 

 the structure normal, or often abnormal through the secondary divi- 

 sion of cell II, which may be replaced by a series of from two to rarely 

 ten or often nine superposed cells, many of which may be distinguished, 

 singly or in pairs, by slight constrictions ; the series of about the same 

 diameter throughout, except the terminal cell which may rarely be 

 once or twice longitudinally divided ; the distal portion of the receptacle, 

 cells III- VI, usually normal, rarely of the " Laboulbariella-type," 

 the whole hyaline and abruptly contrasting with the dark perithecium, 

 of more or less suffused, with yellowish brown, especially at the mar- 

 gins of cells III-IV; cells III and VI usually subequal, cell IV pro- 

 truding below the black, well defined insertion-cell. Appendages 

 variable, the basal cell of the outer slightly longer than broad, some- 

 what inflated and externally suffused, bearing distally one to three 

 branches, usually two, radially placed the basal cell of the outer 

 often suffused externally, bearing distally usually two or three short 

 simple branchlets radially placed, blunt and hyaline; basal cell of the 

 inner appendage much smaller than the outer, bearing a branch on
