upgrowth from the foot on either side, which is black, contrasting and 

 slightly oblique: cell II much smaller, flattened, dirty olivaceous, 

 extending upward anteriorly and separated by a slightly oblique 

 partition from cell VI; which is smaller, concolorous and separated 

 by a strongly oblique septum from the basal cells of the perithecium, 

 which are relatively large, clearly defined and paler dirty yellowish: 

 cells II I- V forming a clearly distinguished, somewhat darker trans- 

 lucent grey olive-colored region, the inner walls of which are nearly 

 vertical, but curve abruptly outward where they are in contact with 

 cell II: cell III larger than cell II, but somewhat similar in shape, 

 except for its curved base, separated from cell IV by a strongly 

 oblique curved septum; cell IV nearly as large as cells II and III 

 combined, externally concave, projecting beyond the insertion-cell 

 to form a broad rounded prominence distally slightly compressed; 

 cell V well defined, triangular, externally convex. Insertion-cell 

 clearly defined, translucent. Basal cell of outer appendage about as 

 long as broad, distally much broader, and bearing a terminal series of 

 three radially arranged branches, themselves once branched above 

 their basal cells; the outer curved outward and externally more 

 deeply suffused with blackish brown externally at the base; the 

 branchlets curved more or less strongly inward, distally hyaline, with 

 olive brown suffusions below, seldom reaching to the tip of the peri- 

 thecium. Perithecium relatively long, curved slightly outward, 

 wholly free above its basal cells; the inner half rich brown, sometimes 

 contrasting with the often much paler dirty yellowish brown outer 

 half, which is concolorous with the long compressed slightly darker, 

 not abruptly distinguished tip, the concave outer margin of which is 

 abruptly much darker; the lips small but well defined. Perithecia 

 100-125 X 25-28 //. Appendages, longest 110 jjl. Receptacle includ- 

 ing protrusion 85-100 X 50-60 n, exclusive of foot. Total length, 

 including foot, 200-228 //• 



On the elytra of Lema sp., New Guinea, M. C. Z. No. 2511. 



This species is so closely related to L. Bruckii that I have hesitated 

 to separate it specifically, and it may prove to be merely a well marked 

 variety when a large series becomes available for examination. The 

 type material includes a half dozen specimens in good condition, all 

 of which show the characteristics above described. 



Laboulbenia rhinoceralis nov. sp. 



Receptacle short and stout, subtriangular, the basal cell larger 

 than the subbasal, longer than broad, hyaline becoming tinged with
