NEW INDO-MALAYAN LABOULBENIALES. 29 



On the right margin of the inferior surface of the abdomen of Gryllo- 

 talpa Africana Palis. Samarang, Java. 



This species is most nearly related to T. brcvis, from which it is 

 most readily distinguished by the form of its perithecium, especially 

 at the tip, as Avell as Ijy its somewhat more highly developed receptacle. 

 The appendages in the six types are all in bad condition and it is not 

 possible to determine the exact character of the secondary branches 

 which it bears. The latter appear to I)e similar, however, to those 

 of T. brcvis and T. cladophorus. 



Dichomyces gracilis nov. sp. 



Basal cell of the receptacle hyaline, broader than long; middle cell 

 of the lower tier barely translucent, the lateral cells opaque, wholly 

 united to the middle tier, and extending upward above the base of the 

 terminal tier, no portion being free ; the middle tier pale dirty yellowish 

 brown, concolorous with the terminal tier and the perithecia, and 

 consisting of series of from six to fifteen cells on either side of the 

 median cell; the two series bent upward and usually strongly inward, 

 so as to overlap the distal tier nearly to the insertion of the primary 

 perithecia; the terminal tier consisting of series of from six to fifteen 

 cells, on either side of the median cell, which bend upward rather 

 abruptly. Perithecia two to four, usually two or four, rarely more, 

 very slender and elongate, with a venter, neck and tip, and even a 

 stalk-portion often more or less distinctly differentiated at maturity; 

 the ^•enter slightly inflated just below the mid-region, and narrower 

 toward the base, faintly purplish, tapering slightly to the neck-part 

 which is perhaps a third as long and of equal diameter throughout; 

 the tip slightly darker, moderately well distinguished, tapering to a 

 broad flattish apex without appendages. Appendages relatively short, 

 hyaline, the basal suffusion unusually prominent. Antheridia well de- 

 veloped, purplish brown. Perithecia 200-300 X 22-30 /jl. Receptacle, 

 to base of primary' perithecia, 125-160 /x, to tips of lateral series 150- 

 235 /i. Appendages 20-25 /z. Greatest width distally 60-110 m- 



On the anal appendages of an undetermined Staphylinid near Phi- 

 lonthus. No. 1416, Java (Rouyer). 



This species is most nearly allied to D. Argentinus Speg. from which 

 it appears to differ in its peculiar incurved middle tier, the form of its 

 perithecia, which occur only on the terminal tier, and in its much 

 shorter appendages.
