On Copfea armata Lnp., Brit. Mus. No. 595, Santarem, Amazon 

 River, Brazil. On elytra and superior prothorax. 



Laboulbenia corethropsis nov. sp. 



Perithecium relatively large, translucent brown or yellov(?ish brown, 

 generally larger distally through a subterminal external bulge, the tip 

 moderately well differentiated, often bent rather abruptly inward, wholly 

 blackish brown or hyaline in the median line, the inner lip-cells smaller 

 and usually more prominent than the outer, sometimes overlapping them, 

 the whole perithecium free from the receptacle. Receptacle short and 

 rather stout, cells II-IV becoming externally blackish brown, the rest 

 concolorous with the perithecium ; cells III and IV rather prominent. 

 Outer appendage wholly opaque, its successive cells indistinguishable as 

 are the basal and insertion-cells, consisting of a blackened axis erect or 

 bent outward, from the inner side of which arise several more or less 

 blackened branches, the basal portion of the appendage only, as a rule, 

 remaining. The inner appendage, consisting of a basal cell which is in- 

 distinguishable from the insertion-cell, being quite opaque, producing 

 a branch on either side, the axis of the branches erect, becoming 

 blackened and opaque, except the inner margins of the distal cells, bear- 

 ing externally from six to ten or even more branchlets which are more 

 or less deeply suffused. The general habit suggesting a species of 

 Gorethromyces. Perithecium 130-150 X 30-33 /x. Total length to tip 

 of perithecium 190-240 yu,; to insertion-cell 90-130 ;u.. Greatest width 

 40-50 jU. Appendages, longest (broken) 185 fj.. 



On Miscelus Javanus Klug., Hope Collection, No, 304, Java; on Mi- 

 scehts sp., Paris Museum, No. 114, New Guinea. On inferior surface of 

 abdomen, and on elytra. 



Laboulbenia corrugata nov. sp. 



Perithecium rather small, irregular, free from the receptacle except at 

 the base, blackish brown, darker and almost opaque below, a rounded 

 distal elevation extending completely round the perithecium, broader 

 externally, forming a nearly opaque broad collar above which the tip is 

 very abruptly distinguished ; the latter subhyaline basally, a dark median 

 external and internal suffusion, the lips translucent, faintly brownish, 

 the two outer rounded and curved inward between the two inner, which 

 form two free slightly unequal divergent blunt-pointed projections. Re- 

 ceptacle rather long and slender, pale brownish yellow with deeper
