Laboulbenia celestialis nov. sp. 



Perithecia almost wholly free, rather deeply suffused with dark red- 

 dish brown except the almost hyaline basal wall-cells ; tapering slightly 

 to the well distinguished rather large tip, which is turned slightly out- 

 ward, the lip-cells blackened except around the pore. Receptacle 

 uniformly pale dirty brown, rather short and stout, somewhat abruptly 

 expanded below the perithecium ; cell IV broader than insertion-cell. 

 Outer appendage consisting of a somewhat rounded basal cell deep brown 

 externally and bearing usually two branches placed antero-posteriorly, 

 the basal cell of the outer nearly round, deep brown externally and 

 bearing two branches placed antero-posteriorly which are very long and 

 slender, remotely septate and more or less suffused with dirty brown : 

 the inner appendage consisting of a smaller basal cell producing a branch 

 on either side, the basal cells of which are short with suffused septa and 

 bear solitary antheridia or short sterile branches which are blunt and 

 shorter than the perithecium. Perithecia 110 X 35 it. Total length to 

 tip of perithecium 2<s0 \i ; to insertion-cell 156 it. Greatest width 55- 

 60 p. Appendages (longest) 400 i*. 



On Drypta lineola Dej., Brit. Mus. No. 507, China. Elytra. 



Laboulbenia ceratophora nov. sp. 



Perithecium wholly free, borne on a short nearly hyaline stalk, tinged 

 not deeply with brown, for the most part nearly straight, rather slender, 

 hardly inflated, the outer margin usually slightly concave ; tapering 

 slightly and rather abruptly to the peculiarly modified tip; the tip black 

 except externally immediately about the pore, a large blunt tooth-like 

 prominence projecting inward the upper surface of which is nearly 

 horizontal while it is continued upward and outward into a longer 

 more slender horn-like bluntly tipped outgrowth, the lower or external 

 margin of which may be partly hyaline. Receptacle yellowish tinged 

 with brown subdistally, rather narrow distally, cell IV small and 

 hardly longer than cell V. Insertion-cell opposite the distal extremity 

 of the short perithecial stalk. The basal cell of the outer appendage 

 longer and narrower than that of the inner, becoming concolorous with
