Receptacle 1100 X 75 /x. Appendages about 185 /a. Total length to 

 tip of perithecium 1150 /a. 



A single mature specimen on Thyreopterus armatus Cast., Madagas- 

 car ; Berlin Museum, No. 933. 



Laboulbenia obliquata nov. sp. 



Color pale amber yellow. Perithecium almost wholly free, distally 

 bent abruptly outward or almost recurved; the base slightly inflated; 

 tapering somewhat, distally, to the apex ; the tip hardly distinguislied, 

 irregularly bent or twisted; the asymmetrical lip-cells forming irregular 

 projections, the two inner subtended by unequal dark patches. Subbasal 

 cell of the receptacle somewhat longer than the basal, nearly as broad as 

 the distal portion of the receptacle; cells III and VI subequal ; cell IV 

 subtriangular ; cell V broad and short, carrying the thick contrasting 

 black insertion-cell out free from the perithecium. Outer appendage 

 simple (or distally branched ?), slightly divergent ; the basal cell some- 

 what longer than broad, its basal third or more obliquely involved by the 

 opacity of the insertion-cell : the basal cell of the inner appendage similar 

 to that of the outer, without suffusion, bearing a short branch on either 

 side, each of which may bear several branchlets. Spores 45 x 3.5 /x. 

 Perithecia 165-170 X iO jx. Receptacle 185-200 X 45 ^. Total length 

 to tip of perithecium 325-360 ix. 



Oo elytra of Coptodera gagatina Dej., Brazil ; Berlin Museum, 

 No. 978. 



Laboulbenia Oedichiri nov. sp. 



Tinged with smoky brown. Perithecia falcate, strongly bent toward 

 the appendages, pale smoky brown, tapering symmetrically, or nearly so, 

 to the base and apex ; the basal cells forming a short narrow hyaline 

 stalk ; the tip not differentiated, suffused with deep blackish brown, 

 except the pale or hyaline blunt apex, the outer lips most prominent. 

 Receptacle more or less distinctly punctate, relatively long and of nearly 

 equal diameter throughout, often slightly geniculate through an enlarge- 

 ment of the basal cell, which is relatively very large just below the sub- 

 basal cell, which is smaller and separated by a more or less oblique 

 septum; cell III relatively small, distally more prominent on the inner 

 side; cells IV and V very small, nearly equal ; cells III and VI sub-' 

 equal. The insertion-cell small, rather thick, wholly free and separated 

 from the stalk of the perithecium by about half the width of cell V. 

 The basal cell of the outer appendage larger, sometimes inflated, bearing
