On Harpaliis Pennsylvanicus. Connecticut. 



Occurs in usually single, crowded tufts on the legs of its host. It 

 is a rare species, allied to L. elegans, from which it is at once distin- 

 guished by its pseudoparaphyses. Described from twenty-six mounted 

 specimens. 



Laboulbenia paupercula nov. sp. 



Color brown to blackish or slightly olive. Perithecium rather 

 broad ; the apex hyaline about the pore, black on the inside. Pseu- 

 doparaphysis single ; hyaline, slightly smoky near the base, simple or 

 once dichotomously branched above the supra-basal cell : a usually 

 short antheridial branch arises from the left side of the basal cell (the 

 pseudoparaphyses being considered as placed anteriorly) ; disk of in- 

 sertion oblique, about one quarter of the distance from the base to the 

 apex of the perithecium. Cells (1) and (2) of the receptacle rather 

 short: (2) separated from (3) and (6) by usually oblique septa : cell 

 (5) usually wholly or partly free from the perithecium, or sometimes 

 obsolete : spores of usual type 45 X 4.5 fx. Perithecia 100 X 40 //,. 

 Pseudoparaphysis, maximum 350 /a. Total length to tip of perithe- 

 cium 160-222 ft. 



On Platynus extensicollis and a Carabid beetle (undetermined) 

 found in dry fields. Connecticut. 



A small and inconspicuous species, usually growing scattered on the 

 thorax or elytra of its host. It is distinguished from all other de- 

 scribed species by its anomalous single paraphysis. Described from 

 twenty mounted specimens. 



Laboulbenia scelophila nov. sp. 



Color olive or smoky olive, cell (1) usually colorless. Perithecium 

 large, subcylindrical, greenish olive, tapering somewhat abruptly to 

 the rather small apex ; which is hyaline about the pore, blackish on 

 either side, and bent slightly towards the pseudoparaphyses. Pseudo- 

 paraphyses three, the outer and inner arising from two main basal cells, 

 the basal cell of the third inserted like a wedge between them, and 

 thus arising from the septum which divides them : all three pseudo- 

 paraphyses once to twice dichotomously branched and very strongly 

 curved inwards so as usually to pass beyond and partly conceal the 

 apex of the perithecium ; disk of insertion horizontal, situated a little 

 more than one third of the distance from the base to the apex of the 

 perithecium. Receptacle short, tapering evenly to a slender base : cell 

 (2) twice as long on the outer as on the inner side, separated from
