rounded. Perithecium 66 X 16 y., the stalk-cell 40^5 X 13 m- Pri- 

 mary appendage 25 /z; the longer branches 250-275 m- Receptacle 

 about 28 fx, the free part of its prolongation 24 X 4 /i. Total length 

 to tip of perithecium 135-145 ji. 



On the abdomen and prothorax of Stilicus Ceylonensis Kr. Buiten- 

 zorg, Thompson (Type) No. 2488; No. 2077, Samarang. 



Allied to C. Stilici and differing especially in its appendage and re- 

 ceptacle. 



Corethromyces appendiculatus nov. sp. 



Receptacle consisting of two very small cells, the basal hyaline, or 

 but slightly suffused, the subbasal more or less deeply involved by a 

 suffusion which is continuous with that of the main axis of the append- 

 age. The latter dark blackish olivaceous, deeper externally, the dark 

 septa clearly visible, the cells four or five in number, the three lower 

 larger, the basal closely united to the stalk-cell of the perithecium, 

 the subbasal often strongly convex, the distal bearing a terminal and 

 one or two subterminal branches, the latter from the inner side; the 

 branches sometimes sparingly branched, short, hyaline, except the 

 basal cells of the terminal one which is a continuation of the main axis. 

 Perithecia relatively short and stout, the stalk-cell but slightly larger 

 than the basal cell of the appendage, to which it is almost wholly 

 united; often separated from the perithecium which may diverge 

 from it at an angle, crossing the axis of the appendage, by a distinct 

 external constriction; the basal cell-region hyaline, not distinguished 

 from the portion above it which becomes gradually broader and more 

 deeply suffused with olive brown from below upward; the middle 

 third broadest, the outer margin rather strongly convex; the tip short 

 and broad, not at all distinguished, its inner margin deeply suffused, 

 the suffusion extending upward into a rather slender curved appendage 

 formed from an outgrowth of one of the lip-cells; another of the lip- 

 cells prolonged to form a suffused projection about half as long, 

 straight, with broad base and rounded tip, the other two lip-cells 

 ending in dissimilar, small and unequal, asymmetrically placed 

 hyaline protrusions. Perithecia 50-60 X 16 yu; the stalk-cell 8-10 X 

 5 ijl; the free part of the longest terminal appendage about 6 X 2 /x. 

 Appendage, main axis 28-45 X 7 /.i, the hyaline branches about 28 /i. 

 Total length to tip of perithecium 70-85 /x. Receptacle 10 X 5 /U-
