446 PROCEEDINGS OP THE AMERICAN ACADEMY. 



ceptacle rather slender, tapering to the base, consisting of (invariably ?) 

 ten superposed cells, exclusive of the foot-cell, which is not always 

 wholly blackened. Appendage as in G. rostratus, the numerous branches 

 and branchlets rather slender, not very long, forming a rather compact 

 tuft more or less appressed around the base of the perithecium. Perithe- 

 cium, ascigerous portion about 85 X 35-40 /i, neck to recurved portion 

 475-500 X 20-25 fx, recurved portion about 125 n, tooth-like projec- 

 tions 15-35 X 6-7 (i. Receptacle (ten superposed cells) 130-150 n. 

 Appendages (longest branches) 175 X 3 ^t/. 



On a small hydrophilid beetle, Paris, Mus., No. 11, lies Mariannes, 

 on under surface, and legs. 



Ceratomyces elephantinus nov. sp. 



Closely resembling O. denticulatus, rather faintly tinged with pale 

 amber brown, the neck proportionately somewhat broader ; the upper 

 three sevenths to four ninths abruptly recurved, certain adjacent cells of 

 two opposite rows just below this curvature producing broad rather short 

 blunt tooth-like outgrowths, one to two and three to four in each 

 respectively; the tip broad slightly and irregularly sulcate. Receptacle 

 consisting of from seventeen to twenty-two squarish or flattened cells, 

 sometimes hardly broader distally. Appendage producing numerous 

 long slender flexuous branches repeatedly branched. Perithecia, asci- 

 gerous part about 140 X 65 f.i, neck to recurved part 475-525 ^w, re- 

 curved part 390-400 ^. Spores 70 X 3.5 ^. Receptacle 375-550 (i. 

 Longest branches of appendage 600 fx. 



On Hydrohiiis sp. ?. Eustis, Florida, October. On legs. 



Ceratomyces rhynchophorus nov. sp. 



Hyaline. Receptacle long slender, but slightly narrower below, con- 

 sisting of about forty (thirty-five to fifty) superposed cells, wider than 

 long ; those in the lower half more flattened, the foot small. Perithe- 

 cium lateral, nearly erect, slightly divergent ; a short but definite stalk- 

 cell ; the cells at the base greatly elongated, extending some distance up 

 around the ascus mass and forming- together with the large elongated 

 supporting cell a broad sterile base to the perithecium which is not differ- 

 entiated from its main body; the cell rows consisting of but five cells, 

 including the very small lip-cells, and the cells of the sterile base ; the 

 three upper tiers of cells forming an abruptly differentiated, thick walled, 

 long, tapering beak-like termination, curved outward or inward, often
