Male individual consisting of four superposed cells terminated by the character tic blackish pro- 
jection, the distal cells producing a dense appressed tuft of coherent antheridial branchlets and antherdia 
the subbasal cell usually giving rise to a fertile branch, simple or furcate, which produces secondary mal< 
receptacles consisting of irregularly double straggling series of cells, some of which are sterile, while others 
bear short-stalked, unilateral, dense antheridial tufts similar to the primary one (which may souk times 
be lacking?). 
Female individual colorless. Primary receptacle as in the male, terminated by two short cells, the 
upper of which bears distally the characteristic blackish minute foot-like projection, the subbasal cell 
producing a simple or furcate fertile branch. The fertile receptee* like those of the male, often < n ■ ping 
extensively, consisting of an irregularly double series of obliquely seriate cell*, sterile <>r fertile without 
definite sequence, the whole plant producing sometimes twelve or even more perithecia, developed as :, 
rule in irregularly acropetal succession. Perithecia snbsessile, inflated below, attenuated above. th<

Since repent males and females usually grow together, the antheridia and perithecia often appear to 
arise from one plant, but this is never the actual condition. The specie* can hardly be confused with 
any other, unless perhaps with H. Anaphrtce, to which it is most nearly alhed; but bom which H may 
be distinguished by the repent habit in both sexes, and by the shape of the per.th.-na. I he specie*, i 
doubtless as widely distributed as is its cosmopolitan host, the common "water bug or I rotor, hug 
well known to housewives.
