prominence corresponding to the point of separation between the basal 

 and subbasal wall-cells, the perithecium tapering thence to the sym- 

 metrically rounded apex of the relatively narrow tip; the basal cell- 

 region distinguished on the inner side only, by a slight indentation 

 marking the base of the lower wall-cell. Perithecium 80-94X35^2 /x; 

 the stalk-cell 98-120X15ju. Receptacle to tip of appendage 38 ^t. 

 Total length 185-125 /x. 



On the tips of the elytra and the adjacent free portion of the abdo- 

 men of Antkicus parvus Pic, Temperley and Llavallol, No. 1513A. 



Distinguished from D. Anthici, to which it is very closely allied, 

 chiefly by the angular or triangular form of it perithecium. 



Autophagomyces nov. gen. 



Male individual, attached to the basal cell and foot of the female, 

 consisting of several superposed cells and bearing terminally and 

 laterally from one to several large flask shaped simple antheridia. 



Female individual consisting of a single basal cell from which the 

 stalk-cell of the perithecium arises distally. Ascogenic cell single, 

 spores 1-septate. 



Although five species of this type have been examined and several 

 individuals destroyed in an attempt to isolate the spores, I have 

 found it impossible to determine whether the male and female spores 

 are more definitely associated than in the other unisexual genera of 

 this type. It is therefore possible that what I have assumed to be a 

 male individual may be an antheridial branch, which arises from the 

 base of the basal cell of the female, although such a condition seems 

 improbable. The relationships of this genus are evidently with 

 Dioicomyces, the species of which also occur, for the most part, on 

 Anthicidae, and with Amorphomyces which the female very closely 

 resembles, except for its septate spores. 



Autophagomyces Platensis nov. sp. 



Male individual consisting of three or four superposed cells exclusive 

 of the foot and bearing one to three antheridia. Total length to tip 

 of terminal antheridium 53-60X5 /u. Antheridia 25 /j.. 



Female individual. Basal cell slightly broader than long, somewhat 

 suffused with brownish below. Stalk of the perithecium short and 

 stout, broader distally, concolorous with the hyaline or faintly yel- 

 lowish perithecium; which is slightly but distinctly curved through-
