EXTRA-AMERICAN LABOULBEXIALES. 721 



the necks somewhat curved, mostly free, rehith^ely lonj^ and forming 

 two incomplete rows. Primary and secondary stalk-cells of the 

 perithecium subequal, so placed that they appear to overlap on the 

 right and left sides, respectively; the basal cells relatively small, the 

 outer shghtly prominent. Venter straight, its axis coincident with 

 that of the stalk-cell region and receptacle, slightly broader near the 

 base; the neck concolorous, rather stout, slightly curved, nearly 

 uniform throughout, very slightly enlarged at its junction with the 

 abruptly slightly narrower tip; the apex somewhat shorter, hardly 

 tapering, distinctly bent outward, the flat blunt termination with 

 hardly prominent lips. Spores (in perithecia) about 30-35 X 3.5 ijl. 

 Perithecia 190 n, the venter 70-75 X 30-35 /x. Appendage 100-110 X 

 16 /x. Receptacle 210-245 X 21 /x. Total length to tip of perithe- 

 cium 385^50 IJL. 



On a dark fly belonging to an undetermined genus of the Anthomyi- 

 dae. No. 2638, Kamerun. 



This species is closely allied to S. diibius. None of the specimens, 

 which include a number of very young individuals, show any signs of 

 the conspicuous and permanent spine found in the last mentioned 

 species. The snout-like, curved apex of the perithecium and the very 

 slight enlargement below the tip, together with the minute, hardly 

 indicated lips, seem further to distinguish it. 



Stigmatomyces LiMNOPHORAE Thaxtcr. 



The typical form of this species has been found on several flies from 

 Kamerun belonging to the Anthomyidae, Nos. 2640 and 2646 as well 

 as others, while a large form that appears also to be identical with 

 this species and may measure nearly 800 /x in length has been received 

 from Mr. Jacobson and was collected by him in Sumatra on Lucilia (?) 

 and a similar form from the Philippines on Lucilia du.r has been re- 

 ceived from iVIr. Banks. A closely allied form, which does not seem 

 referable to any of the variations of 6'. Limnophorac, has been met with 

 on an anthomyid fly from Kamerun and may be distinguished as 

 follows. 



Stigmatomyces tortilis nov. sp. 



Form comparatively short and stout, slightly cur\ed throughout, 

 especially the neck, uniformly dirty yellowish brown above the hya- 

 line receptacle; the subbasal cell slightly longer than the basal which
