ing from the base to the lower basal cell of the perithecium, which is 

 also subtended by a short cell, below which a third cell extends down 

 to the substratum and from which three or four distally pointed suc- 

 cessively shorter cells are separated laterally, externally, and somewhat 

 obliquely, all of them extending to the substratum. The lowest basal 

 cell of the perithecium associated with a general constriction which 

 it wholly occupies, flattened and connected by a more or less narrow 

 isthmus with a broader portion which lies immediately below the ascig- 

 erous cavity and forms, together with the three remaining basal cells 

 which are more or less rounded and sul)equal, a short nearly symmetri- 

 cal rather al^ruptly inflated base, broader than that of the ascigerous 

 venter; the latter is relatively rather short, slightly inflated, the junc- 

 tions of the wall-cells barely indicated, the outline subeven, the struc- 

 ture of the distal portion similar in general to that of H. tricusindatus; 

 the third wall-cell of the anterior row slightly concave, not at all 

 prominent, its margin continuous with that of the cell below, subtend- 

 ing an erect incurved spinous process, a similar process arising from the 

 fourth wall cell of one of the lateral rows, these two processes extending 

 distinctly beyond the erect spine which subtends the blunt short in- 

 curved tip of the perithecium. Perithecium, from basal cells to tip of 

 upper spine, about 92 ju; to tip of lower spines about 102 ^t, greatest 

 width 30 /x. Primary receptacle 26 X 7/^; secondary receptacle about 

 60 X 28 IX. Total length to tip of longest spine 180 ^i. 



On the antennae of Pancstkia lobipennis Brunn. Near Peradeniya, 

 Ceylon. 



This species occurs rarely on the above mentioned host, usually 

 singly, and always produces a single pair of perithecia only. It differs 

 in this respect from H. Paranensis and H. fricuspidafus to which it is 

 nearly allied, as well as in minor details of its secondary receptacle 

 and perithecium. The secondary receptacle is considerably twisted, 

 so that it is almost impossible to see its broad face, as in the two species 

 just mentioned. 



Synandromyces Javanus nov. sp. 



Pale straw-yellow throughout. Basal cell of the receptacle erect, 

 narrow, almost completely surrounded by the subbasal cell and the 

 stalk-cell of the appendage, which are nearly ecjual and lie almost 

 symmetrically on either side of it, extending nearly to its base, meeting 

 for a short distance above it. Body of the antheridiiun consisting of
