very thick, fonuing an erect tapering bluntly pointed terminal appendage, 

 at the base of wbich the papillate apex of the lip-cells projects on the 

 right side ; the fifch cell of the external row of wall-cells growing out 

 to form a subterminal slender appendage, eight-celled in the type, distally 

 attenuated, its terminal cell bearing one or two slender branches. Ap- 

 pendages consisting of from four to five superposed cells, the distal ones 

 appendiculate (the branches mostly broken). Perithecium 185 X 40 ^u. 

 The appendage without branches 82 ^u, the branches 150//; the rostrate 

 terminal cell 50 X 17 ^a (at base). Receptacle 85 X 48 fu. Spores about 

 70 X 3.5 fi. Appendage, broken, without branches 70^. 



On Berosus sp. indet; Eustis, Florida, October. On the inferior 

 surface of abdomen and thorax. 



Ceratomyces Californicus nov. sp. 



Allied to C. camptosporus. Amber brown. Receptacle relatively 

 slender, consisting of three small superposed cells surmounted by two 

 similar cells which form the base of the appendage and perithecium; the 

 foot small, normal. Perithecium short and stout, from two to three 

 times as broad distally as at the base ; about twenty cells in each of the 

 inner rows of wall cells, the inner margin convex, distally abruptly bent 

 inward to the short beak-like apex ; the conformation of the tip, the inner 

 margin of which is thus horizontal or even oblique, resembling that of 

 C. nrnithocephahis ; about the eighteenth cell of one of the outer rows 

 forming the base of the usually straight rather remotely septate perithe- 

 cial appendage which commonly diverges at an angle of forty-five degrees 

 or even at right angles. Appendage small and slender (the extremities 

 broken in the types) becoming lateral in position. Perithecia 185-200 

 X (base) 30-40 (distal portion) 70-85 ^u. Receptacle 50-70 X 25 jj. 

 Total length to tip of perithecium 250-300 u. 



On Tropisternus dorsalis Brulle. California. On the left anterior 

 inferior angle of the prothorax. 



Ceratomyces ornithocephalus nov. sp. 



Allied to 0. furcatus. Hyaline or becoming more or less suffused 

 with amber brownish. Perithecium relatively rather small, the ex- 

 ternal margin somewhat concave, the inner convex, the four distal 

 cells of the eight external wall-cells rather abruptly enlarged, their ex- 

 ternal walls much thickened and forming an irregularly rounded crest- 

 like prominence, the distal half of the margin of which becomes abruptly
