EXTRA-AMERIC.W LABOULBENIALES. 749 



perithecium small and narrow, constricted in the middle, with a slight 

 twist; the secondary stalk-cell half as large, obliquely separated; 

 the basal cells surrounding the base of the ascigerous cavity, and 

 forming about one fifth of the stout body of the perithecium, which 

 comprises the venter-, neck- and tip-regions, the neck-region some- 

 what broader and separated from the tip-region by a slight indenta- 

 tion; the relatively broad apex abruptly somewhat narrower, the lip- 

 cells developing four erect appendages; two lateral and opposite, 

 more slender, longer, tapering slightly to a blunt point, each subtended 

 by a small rounded outgrowth hardly longer than wide; one posterior, 

 straight, tooth-like, tapering evenly from a broad base to a small 

 rounded apex, and somewhat shorter: one anterior opposite the last 

 and somewhat shorter, similar, rather abruptly broader distally, 

 the extremity broadly rounded. Spores 28 X 3 /i. Perithecium to 

 tips of appendages, including basal cell region, 135 n; the appendages, 

 longer, 30 yu. Appendage 60 X 7 )u at base. Receptacle 60 X 18 fx, 

 including sharply pointed foot. Total length about 200 fx. 



On the elytra of Chilomenes lunata Fabr. No. 2158, Nairobi, 

 British East Africa, Mearns. 



This species is intermediate between »S. virescens and S. coccinel- 

 loides; resembling the former in the character of its appendage, and 

 to some extent, in the form of the perithecial outgrowths, more closely 

 than the latter. Its xery narrow, short stalk-cell and the form of the 

 body of the perithecium recalls S. coccinelloides. The erect, sym- 

 metrically placed perithecial appendages are different from any of 

 the varieties of the two related forms.
