ifi. Perithecia 130-140 X 30-35 |U exclusive of the variably developed 

 neck, which may be 18/x long. Total length to tip of perithecium 2G0ju ; 

 to insertioa-cell 100 ^tt; width 40^. Longer appendages 200-270^. 



On Orthomus aquilus Coquer, Algeria ?, Paris Museum, No. 41. On 

 margin of elytra. 



Laboulbenia pallida nov. sp. 



Perithecium almost wholly free from the receptacle, colorless becoming 

 faintly yellowish, bent outward ; the prominent tip abruptly distinguished, 

 coarse lipped, hyaline except for an inner blackish patch. Receptacle 

 concolorous with the perithecium, the basal cell large and broad, longer 

 than cell II, the cells of the distal portion relatively small, cell III 

 roundish, about as large as cells IV and V together. Insertion-cell thick, 

 contrasting purplish black. Outer appendage consisting of a basal cell, 

 rectangular or distally enlarged and producing usually two, sometimes 

 but one branch, the branches once or even twice branched, the ultimate 

 branchlets sometimes very elongate and attenuated : the inner appendage 

 consistincr of a basal cell much smaller than that of the outer and some- 

 times lateral in position, bearing one or two branches which may be 

 short or elongate like those of the outer appendage. Perithecia 70 X 

 2b (X. Total length to tip of perithecium 110-175 /x; to insertion-cell 

 85-120 ju. Appendages, longest 285 ^a. 



On a Carabid allied to Harpalus, Paris Museum, No. 94, Java. On

Laboulbenia Papuana nov. sp. 



Perithecium nearly two thirds free, straight or curved slightly outward, 

 the inner margin convex ; pale brownish yellow, the tip rather well dif- 

 ferentiated, blackish ; the hyaline irregularly prominent lip-edges turned 

 inward. Receptacle elongate, cell II, and cell I except at its base, con- 

 spicuously tinged with blackish and faintly marked by fine transverse 

 striations, the rest of the receptacle concolorous with the perithecium ; 

 cell lY externally concave, the whole receptacle more or less prominently 

 bent anteriorly in the region of cells III and VI. Insertion-cell broad, 

 horizontal, black, narrower than cells IV-V. The basal cells of the 

 appendages simple and distinct, the outer producing a single branch 

 which may branch once ; the branchlets short ; the basal cell of the inner 

 appendage producing two small branches which may be once branched. 

 Spores about 65 X 5.5 n. Perithecium 160-200 X 55-65 ^. Total length 

 to tip of perithecium 650-880 /a ; to insertion-cell 544-700 ^. Appendages, 

 longest seen, 140 ^u.
