NEW INDO-MALAYAN LABOULBENIALES. 35 



two superposed pairs of rounded cells separated by indentations; 

 the upper smaller, each bearing a single antheridium distally. Stalk- 

 cell of the perithecium short and very slender, the very broad base of 

 the perithecium arising from it laterally and asymmetrically, the body 

 short and stout, much inflated, asymmetrical when viewed sidewise, 

 tapering abruptly distally; the tip itself not well distinguished, broad; 

 the apex rounded, slightly sulcate. Perithecium 120-135 X 40-50 fx. 

 Receptacle, including stalk-cell, of appendage, 40 X 32 /x, free portion 

 of antheridial appendage, to tips of antheridial cells, 35^0 X 22-25 (jl. 

 Total length to tip of perithecium 155-175 /x. 



At the base of the posterior legs of a cryptophagid beetle, belonging 

 to the section Telmatophilini. No. 2147, Samarang, Java. 



This species differs from others known to me in having only two 

 antheridia. A second and very distinct species was found on the 

 same host, having a much reduced appendage and a much longer 

 black perithecial stalk-cell. The single specimen, however, is too 

 broken for description. 



Arthrorhynchus Nycteribeae (Peyr). 



Specimens of Pcnicillidia Jenynsi Wstw. collected at Peradeniya, 

 Ceylon, and infested by this species have been very kindly communi- 

 cated to me by Dr. Hugh Scott. The individuals appear to corre- 

 spond in all essential respects to European material and differ only in 

 their somewhat larger size, some of them having a total length of 

 about a millimeter, and paler color. 



Stigmatomyces Stilici nov. sp. 



Basal cell of the receptacle about twice as long as the subbasal, 

 narrower below and more or less deeply suffused with blackish brown; 

 distally hyaline and broader than the base of the subbasal cell from 

 which it is thus abruptly distinguished; subbasal cell faintly suffused 

 with yellowish brown, about as broad as long, its basal portion thin- 

 walled and distinctly differentiated, five sided, distally pointed and 

 obliquely separated from the stalk-cell of the appendage on one side 

 and that of the perithecium on the other. Stalk-cell of the appendage 

 subtriangular, externally convex, the basal septum oblique and practi- 

 cally continuous with the short inner margin, which is in contact with
