THAXTEK. — AKGENTIN'E LABOULBENIALES. lOi 



Laboulbenia Monocrepidii nov. sp. 



Cells I and II hyaline or faintly olivaceous, narrow, cell II rather 

 abruptly broader distally, and obliquely separated from cell III by 

 an incurved partition; the distal portion of the receptacle deeply 

 suffused with olive-brown, deeper externally below the very thick 

 dark insertion-cell; cell V paler. Basal cells of the appendage 

 suffused, subequal, each bearing a short single simple rarely once- 

 branched erect similar appendage, the basal cell of which is subhyaline 

 or more faintly suft'used, and distinguished above and below by a 

 constriction and by a blackened septum, the rest of the appendage 

 short hyaline, tapering to a blunt point, the inner appendage single 

 short simple, replacing a single small short antheridium found in 

 younger specimens. Perithecium about three quarters free, deeply 

 tinged throughout with olive-brown, slightly inflated; the tip long, 

 not abruptly distinguished, suffused with blackish, the black shades 

 extending downward separated by pale areas; the lips asymmetrical, 

 the edges irregular, outwardly oblique, hyaline. Spores 75X4.5 /x. 

 Perithecia 120-135X40-45 /z. Receptacle 150-225//. Longest ap- 

 pendage 80-110 )U. Total length to tip of perithecium 250-325 /x. 



On the elytra etc. of Monocrepidius sp., Palermo, No. 1683 and also 

 at Llavallol. 



A clearly distinguished species, the first as yet recorded on a mem- 

 ber of this family (Elateridae). 



Laboulbenia fuscata nov. sp. 



Receptacle tapering evenly to the small foot, dirty olive brown, 

 cells I and II paler, cell IV externally rounded and prominent below 

 the rather broad insertion-cell which is but little darker than the cells 

 below it. Basal cell of the outer appendage roundish or bell shaped, 

 deep reddish brown, hardly larger than the inner, the appendage 

 externally blackened and curved abruptly outward above it, short, 

 separated by an opaque septum from its deeply suffused red<^lish 

 brown basal cell, and bearing two to three suberect or incurved short 

 branches; the inner basal cell bearing two deep reddish brown, 

 somewhat bell-shaped cells, terminated by a single short erect usually 

 simple appendage. Perithecium free, except at the very base, dark 

 translucent yellowish olive, subsymmetrical, curved slightly outward, 

 twisted one quarter so that the tip is viewed at right angles to its 

 normal position; the tip large, characteristically and slightly inflated,
