very small much narrower squarish subbasal cell; the terminal cell 

 hyaline elongate slightly inflated below, tapering distally; sometimes 

 extending to or beyond the tip of the antheridium. Total length, 

 including foot, 60 ;u. Antheridium, including stalk-cell, 35 m; its 

 neck 8 /i. Appendage, 20-30 jx. 



Female individval, becoming dark blackish brown, the primary 

 appendage erect, consisting of a larger basal cell hardly twice as long 

 as broad, a narrower subbasal cell broader than long, and a terminal 

 cell, hyaline or paler distally, longer than broad, inflated or degenerat- 

 ing. Perithecia usually not exceeding three in number, elongate, 

 straight or curved, blackish brown, very slightly inflated; the tip 

 bluntly rounded, or asymmetrical and snout-like, when viewed later- 

 ally ; the hyaline apex subtended, on the inner side, by a darker shade. 

 The secondary appendages of two or three superposed cells, hardly a 

 third as long as the perithecia, alternating with them, or somewhat 

 irregular in position, especially above; the series of cells which bears 

 them, and the marginal extension of the basal cell of the receptacle 

 nearly erect, or diverging from the appendage at an angle of not more 

 than 45°. Perithecia 75-100X15-20 /x. Secondary appendages 25- 

 30 IX. Total length to tip of highest perithecium 100-200 fx; to tip 

 of secondary receptacle 75-120 ix. 



On Atheta sp., Palermo, Nos. 1690, 1965, and 1966. 



This species, which was found not infrequently, appears to vary 

 considerably; the older and better developed individuals becoming 

 very dark, and attaining a considerable size. Such individuals, 

 which usually occur on the abdomen, do not appear to be separable 

 from smaller and paler forms which occur, usually, on the legs, an- 

 tennae and head. 



Rickia Lispini nov. sp. 



Receptacle short and stout, the basal cell small, hardly longer than 

 broad; the main body consisting of a central cell lying between a pair 

 of marginal cells superposed on either side of it, the two lower united 

 below it and separating it completely from the basal cell; while its 

 extremity lies in oblique contact with the lower half, or less, of the 

 perithecium ; the upper marginal cell on one side cutting off one to two 

 small appendiculate cells which subtend the base of the perithecium; 

 the upper marginal cell on the opposite side, bearing two or three 

 to six simple appendages, their origins often lying nearly horizontally, 

 one to five of them arising from single small cells successively separated
