a broadened base, slightly divergent from the main axis, slender, about 

 as long, or a little longer than, the body of the antheridial cell. Length

 60 fjL. Width 8 fjL. 



female individual. Often more or less strongly curved, the terminal 

 sterile cell bluntly pointed, slightly curved, brownish ; the basal cell 

 becoming narrower below, the upper septum convex ; tinged with brown 

 posteriorly as is the rest of the receptacle : the subbasal cell very small, 

 subtriangular ; separated from the terminal sterile cell by a somewhat 

 smaller triangular cell. Stalk-cell of the perithecium hyaline, long, often 

 about the same diameter throughout; the thick wall becoming gradually 

 thicker distally : the perithecium slightly inflated, faintly brownish ; the 

 short, stout, broad, blunt tip slightly distinguished, and nearly symmetri- 

 cal ; the lip-cells forming an unbroken outline, without protrusions. 

 Spores (male) 40 X 4/a, (female) 60 X 6 /x. Perithecium 100-110 X 

 35-45 /x, the stalk-cell 75-115 X 18 /x,. Receptacle including foot 35 X 

 12 /i, the sterile terminal cell 18-25 X 7-9 /a. Total length to tip of 

 perithecium 185-220 yu,.

 nicus Laf. California (Leconte Collection). 



Dioicomyces onchophorus nov. sp. 



Male individual similar to that of D. Anthici, slightly smaller. 



female individual. Usually strongly curved, especially at the base 

 of the stalk-cell ; similar to D. Anthici ; the receptacle, sterile cell, and 

 the stalk of the perithecium, relatively smaller. Perithecium dirty 

 brown, one of the lip-cells protruding in the form of a well defined, 

 lateral, finger-like, erect, straight, or slightly curved, blunt-tipped, con- 

 colorous process ; an irregular anterior elevation or angular prominence 

 is also more or less well defined above the middle of the perithecium. 

 Spores (male) 35 X 4 ^a, (female) 45 X 5 yu,. Perithecia to tip of pro- 

 jection 125-140 X 40-45 /A, the stalk-cell 90 /x. Total length to tip of 

 perithecium 210-230 /a. 



Usually on the basal half or at the base of the left elytron of Anthicus 

 fioralis Linn. Fresh Pond, Cambridge. 



Dioicomyces spinigerus nov. sp. 



Male individual similar to that of D. Anthici, much smaller, the ex- 

 tremity less prominent, or almost horizontal, the discharge tube some-
