sleuder tip, a blackish shade below the nearly hyaline lips which are 

 turned slightly outward. Receptacle amber-colored, deeper anteriorly, 

 cell II sometimes elongate, cell VI very short, so that the base of the 

 perithecium comes opposite cell III. Insertion-cell and the inner margin 

 of cell V usually free from the perithecium. The outer appendage 

 simple divergent, the basal cell very large ; the basal cell of the inner 

 appendage much smaller, bearing one to two short branchlets. Spores 

 o5-40 X 41 jw. Perithecia 120 X 35 /j. Total length to tip of perithe- 

 cium 175-380 fi (longest) ; to insertion-cell 115-275 //. 



On " (Edodactijlus fuscobrunneus," Brit. Mus. No. 397, Chili. On 

 elytra. 



Laboulbenia Oopteri nov. sp. 



Perithecium three fourths or more free, translucent blackish brown, 

 the inner margin evenly curved outward, the outer margin with slight 

 elevations at the septa and curved abruptly inward to form the well 

 differentiated tip which is pale brownish, with dark inferior suffusions. 

 Receptacle concolorous with jDerithecium, except that cells I and II are 

 usually hyaline, the suffused portions sparsely and rather coarsely and 

 distinctly punctate. Insertion-cell broad and black. Basal cell of the 

 outer appendage for the most part very long, bearing distally an outer 

 and an inner branch, the former with blackened basal septum, simple, 

 or once branched in which case the basal septum of the outer branchlet 

 is also blackened. Inner appendage consisting of a very small basal cell 

 bearing a short branch on either side. Perithecia 95-110 X 30-35 (x. 

 Total length to tip of perithecium 175-275 fx ; to insei'tion-cell 85-160 ^. 

 Appendage broken, 200 jw, probably much longer. 



On Oopterus rotundicollis White, Brit. Mus. No. 613, New Zealand. 

 On elytra. 



Laboulbenia Ophoni nov. sp. 



Perithecium free except at the base, short and stout, pale straw-colored 

 or nearly hyaline, somewhat inflated ; the inner margin more convex, the 

 black tip abruptly differentiated on its inner side, black, contrasting, the 

 lip-edges hyaline turned slightly outward. Receptacle short, stout, nor- 

 mal, concolorous with the perithecium. Insertion-cell black, contrasting. 

 The onter appendage divergent, simple or once to three times branched, 

 the ultimate branchlets distally attenuated ; the inner appendage consist- 

 ins of a basal cell half as larcre as that of the outer, bearing; a short branch 

 on either side which may be several times branched, the antheridia borne 

 in small groups. Spores 28x3//. Perithecia 70 X 30-34/1. Total
