46 PROCEEDINGS OP THE AMERICAN ACADEMY. 



Receptacle medium to short, the basal cell hyaline, becoming dirty 

 brownish yellow; cells III and IV deep brownish, the suffusion more 

 or less confined to these cells or involving also cell II and other adjacent 

 cells, the more deeply suffused parts coarsely punctate ; cell III extend- 

 ing upward beside cell IV and distally forming a more or less well- 

 defined external prominence, sometimes as distinct as that formed by 

 the basal cell of the outer appendage ; cells V and VI wholly or partly 

 hvaline, becoming dirty brownish yellow. Insertion-cell small, almost 

 wholly external to cell V, hardly distinguishable, translucent and only 

 finally involved in the opacity of the adjacent cells. Appendages 

 resembling those of L. Galeritae, the basal cell of the outer appendage 

 large, subtriangular, forming distally and externally a rounded promi- 

 nence, from the upper nearly horizontal surface of which arises the 

 first of the oblique series of branches ; the remaining cells of the 

 appendage hyaline, successively smaller, from about six to ten in num- 

 ber, forming the oblique series characteristic of this type of appendage ; 

 each bearing externally a single branch ; the branches relatively short, 

 the basal cell more elongated than the subbasal, both purplish brown, 

 slightly constricted at the dark septa ; the rest of the branch shorter or 

 not much longer than the basal part and consisting of from one to three 

 cells, hyaline or brown below, blunt-tipped ; the basal cell of the inner 

 appendage giving rise to the characteristic series of superposed ramif- 

 erous cells on either side which are closely united to the outer appen- 

 dage, the four or five lower cells of each series producing, as a rule, 

 unicellular branchlets terminated by a pair of brown long-necked anthe- 

 ridia ; the sterile branchlets of the upper and distal cells similar to those 

 of the outer appendage. Spores 45 X 4.5 /x. Perithecia 180-290 X 

 40-48 jx, the stalk 55-125 X 25-35 /x. Receptacle 165-220 fi. Append- 

 ages, greatest total length, 165-185 /x. Total length to tip of perithe- 

 cium 350-725 /x. 



On Galerita sp. (lips of elytra), Venezuela; Paris Museum, No. 75. 

 On tip of abdomen, inferior, of Galerita Lecontei Dej. ; British Museum, 

 No. 521 ; Costa Rica. 



Laboulbenia Megalonychi nov. sp. 

 Hyaline, becoming very faintly tinged with yellowish brown. Peri- 

 theciura about one half or more free, slightly divergent, short, stout, 

 tapering slightly from the broad basal half to the tip ; which is, as a 

 rule, bent abruptly inward, rarely outward, or erect, rather small and 

 well-distinguished by its long external contrasting broadly blackened
