lique, placed above the middle third of the peritheciurn, from which 

 it is wholly separated through the elongation of cell V. Recep- 

 tacle usually elongate, cell V. being continued beyond the inser- 

 tion of the pseudoparaphyses nearly to the lips of the peritheciurn, 

 cells IV. and V. being thus almost superposed. Spores 70 X 5.5 /*. 

 Perithecia 100-120 X 50-55 p. Pseudoparaphyses (long) 270 fi. 

 Total length to tip of peritheciurn 350-375 p : greatest width 75 ft. 



On Schizogenius lineolatus and S. ferruglneus, Connecticut. 



A rare species, at once separable by the peculiar relative position 

 of the pseudoparaphyses, and the unusual elongation of cell V., 

 which is sometimes approached by specimens of L. variabilis. 



Laboulbenia pedicellata, nov. sp. 



Hyaline, becoming brownish, long and slender. Perithecia dis- 

 tally subconical, inflated on the inner side, the apex rather broad 

 and usually somewhat pointed, nearly symmetrical. Pseudopara- 

 physes, when perfect, exceeding the peritheciurn, arising primarily 

 from two basal cells, the outer twice as long as the inner, bearing 

 at its apex a roundish cell, from which arise three branches two to 

 three times subdichotomously branched, the branches curved and 

 more or less hooked at the apex. After fertilization, the inner 

 basal cell produces a number of branches curved towards the peri- 

 theciurn, and often producing secondary branches : disk of inser- 

 tion rather broad, blackish, oblique, inserted just above the base 

 of the peritheciurn. Receptacle long and slender through the great 

 elongation of cell II. Spores 50 X 3.5 /i. Perithecia 90-95 X 

 36-40/1. Pseudoparaphyses 90-100 fi : longest 150 /x. Total length 

 to tip of peritheciurn 300 /z : greatest width 45 fi. 



On Bembidium sp., Maine. 



Allied to L. vulgaris, from which it is distinguished by its slen- 

 der, elongate, cylindrical basal cells, and by its inflated, pointed 

 peritheciurn, which is also differently situated in relation to the 

 insertion of the pseudoparaphyses. 



Laboulbenia vulgaris, Peyr. 



A form referable to this sjiecies, and occurring on the elytra of 

 species of Bembidium, has been received from Washington on hosts 

 collected by Miss Parker, and is also not uncommon on Bembidia 

 taken in Maine. The figures and description given by Peyritsch 

 leave much to be desired, yet the determination seems tolerably 

 certain.
