short stalk-cell; the main body nearly straight or slightly curved, 

 sometimes subsigmoid, relatively rather long, tapering slightly; the 

 tip rather broad, variably modified, often snout-like and irregularly 

 bent, the posterior lip-cell usually prominent or forming a short but 

 well defined concolorous projection; the apex flat or bluntly rounded. 

 Perithecium 55-72 X 12-13 ^t. Appendage with branches 35-50 ^u. 

 Receptacle 9 X 7 ju, the spine-like process 18-55 X 3 /x. Total length 

 to tip of perithecium 75-95 /U. 



On the inferior surface of the abdomen, near the tip of Thinocharis 

 pygmaea Kr. Samarang, Java, No. 2084. 



This species corresponds closely to the numerous forms which com- 

 prise the section of the genus parasitic on Stilici. The basal cell is 

 hardly distinguishable, from its small size and the suft'usion which 

 obscures it, while its relations are further confused from the displace- 

 ment downward of the subbasal cell. It is most nearly related to C. 

 decipiens. 



Corethromyces orientalis nov. sp. 



Basal cell of the receptacle relatively large, wholly blackened 

 and not differentiated from the foot; continued upward to form a 

 blackened prolongation, which is closely united to the subl)asal cells 

 of the receptacle and of the appendage, bending abruptly inward, 

 being free and more slender above the latter; the free portion lying 

 parallel to the appendage, the main axis of which it may equal in 

 length, subbasal cell of the receptacle hyaline, its outer margin concave, 

 below obliquely, or almost \ertically, separated from the l)asal cell and 

 its extension, as well as aliove from the stalk-cell of the perithecium 

 which arises from it externally. ]Main axis of the appendage consist- 

 ing of a basal cell which becomes displaced so that its base seems to lie 

 against the blackened prolongation of the basal cell of the receptacle, 

 the appendage thus becoming turned so as to lie across the stalk-cell 

 of the perithecium, and of two to three smaller terminal cells all of 

 which may bear one or more very elongate attenuated branches or 

 branchlets, the whole quite hyaline. Peritheciiun and its stalk-cell 

 hyaline, or the former faintly reddish purple, the whole subfalcate 

 or even subsigmoid; the stalk-cell well developed, several times longer 

 than broad, its diameter about the same throughout, as broad as or 

 slightly broader than the base of the perithecium, which is usually 

 strongly curved, hardly inflated l)elow, tapering slightly and gradually 

 distally; the tip not at all distinguished; the -apex broad, bluntly
