appendage. Perithecium one half free on the inner side, wholly free 

 externally, concolorous, the l)ody long elliptical or broader below, the 

 tip abruptly distinguished, short, broad, purplish Ijrown, except the 

 bluntly rounded subhyaline apex. Autheridia relatively long, curved, 

 sharp and beak-like. Appendages minute, hardly distinguishable 

 and very few in number. Perithecium G5-100 X 28-35 /jl. Spores 

 50 X 7 ju (in perithecium). Antheridia 15 X 5 /i. Appendages 4 X 

 3.5 M- Total length to tip of perithecium 260-340 X 40-44 m- 



On the inferior tip of the aI)domen of Onthophagus sp. No. 2094, 

 Peradeniya, Ceylon. 



This species which is the first member of the family reported on 

 Scarabeidae, presents no very striking peculiarities. It is distin- 

 guished by its very numerous antheridia and scanty minute appen- 

 dages. 



Rickia compressa, nov. sp. 



Straight or slightly curved, rather stout, subsymmetrical, wholly 

 hyaline. Basal cell very small, subtriangular, the subbasal broader, 

 flattened, sometimes obliquely divided, followed by two superposed 

 pairs of cells above which the receptacle is triseriate; the middle row 

 consisting of from thirteen to fifteen cells, the eight lower squarish, 

 the upper ones extending along the posterior margin of the perithecium 

 against which they are flattened, the two to three distal ones free 

 externally above the insertion of the primary appendage; the free 

 divergent basal cell of which terminates the posterior row of nine to 

 twelve cells; the anterior row^ consisting of eight or nine cells, its 

 external margin evenly continuous with that of the perithecium, to the 

 base of which it extends: a variable but small number of the cells of 

 both the anterior and posterior rows separate a small cell distally and 

 externally, which form the basal cells of the hyaline slightly tapering 

 secondary appendages. Perithecium externally free, straight, erect, 

 rather stout, but slightly inflated, the tip abruptly distinguished, com- 

 pressed, symmetrical, ending in a blunt nearly symmetrical apex. 

 Perithecium, 00-75 X 20-22 /x, not including marginal cells of the 

 median series. Receptacle, to tip of primary appendage-cell, 140- 

 155 /x. Secondary appendages 20-40 X 4-5 /x- Total length to tip 

 of perithecium 175-200 X 32-35 yu-
