Oa abdomen of Plati/stethus cornutus Grav., British Museum, No. 449, 

 Kilburn, England. 



Eucantharomyces Diaphori nov. sp. 



Pale straw colored. Perithecium rather short and stout, its basal cells 

 small, slightly and usually symmetrically inflated; tapering from about 

 the middle to the broad blunt slightly asymmetrical tip, which is sub- 

 tended below the free lips, on the inner side, by the flat trichophoric 

 cell, just above which arises a very slender recurved rigid appendage 

 (not cellular) about 8-9 jx long. Receptacle rather short and stout, the 

 subbasal (anterior) cell somewhat stouter than the basal, the two together 

 somewhat larger than the short stalk-cell of the perithecium. Apj^en- 

 dage relatively large, its basal cell short subtriangular, the upper and 

 lower septa oblique, the subbasal cell slightly longer than broad, its upper 

 two thirds bordered by the marginal cell which terminates in a slender 

 stiff straight spine-like process about 11-12 /x long and slightly diver- 

 gent ; the antheridial cells in five rows of five, four, three, three, and two 

 cells respectively ; a single additional cell sometimes jDcrsistiug above the 

 antheridial cavity ; the discharge tube bent outward and slightly upward, 

 the tip bluntly conical with a slight basal enlargement. Spores 40 X 

 3.5 /x. Perithecia 120 X 30 /x. The stalk-cell 30 X 18 /x. Appendage 

 70 ,u long, the antheridium 28 X 21 /x. Receptacle 45 X 24 /x. Total 

 length to tip of perithecium 180 /x. 



On Diophorus tenuieornis Chaud., British Museum (Biologia Coll.), 

 No. 714. Oaxaca, Mexico. On mid-elytron. 



Eucantharomyces spinosus nov. sp. 



Perithecium straw colored, rather stout, inflated, tapering to the broad 

 asymmetrical tip which is slightly sulcate ; the outer lips often larger 

 than the inner, the latter bordered or subtended by the more deeply 

 colored trichophoric cell which, in mature specimens, is not very con- 

 spicuous ; the stalk-cell rather short. Receptacle short, the cells nearly 

 equal. Appendage much as in E. Diaphori, more slender, the marginal 

 cell extending nearly to the base of the subbasal cell, distinctly enlarged 

 below a terminal spine-like process, which is usually nearly erect; the 

 antheridial cells in three rows of five, tliree (relatively large) and one to 

 two cells respectively, the discharge tube large and broad, nearly trun- 

 cate, bent abruptly upward from the base. Spores 35-40 X 3.5-4 /x. 

 Perithecia 138 X 41 /x. Appendage 70 X 14 /x, the antheridium 35 X
