Basal cell of the receptacle rather narrow, more than twice as long 

 as the squarish sub-basal cell. Spores 32 X 3 //.. Perithecia 55 X 

 15 fx to 75 X 22 /jl. Basal and sub-basal cells 30-45 /* in length. 

 Perithecial appendage 30-33 X 4 [x. Total length to tip of peri- 

 thecium 100-130 /x. Greatest breadth 30-36 lk. 



On Laccophilus macidosus, Connecticut. 



A rare species, confined to the anterior pair of legs of its host, 

 and distinguished at once by its clavate perithecial appendage 

 which corresponds to the similar horn-like projection from the 

 perithecium of H. paradoxus. 



Heimatomyces paradoxus, Peyr. 



This species occurs not uncommonly on the edge of the left 

 elytron of Laccophilus maculosus in company with H. marjinatus. 

 The ascogenic area is so placed that the asci and spores are much 

 distorted at maturity; but the latter do not appear to have the 

 peculiar shape represented by Peyritsch. 



Heimatomyces Halipli, nov. sp. 



Strongly suffused with yellowish brown. Perithecia inflated, 

 more strongly externally, rounded to the papillate tip. Base of 

 receptacle composed of three superposed cells, the lower triangular, 

 suffused with blackish at the base; the two upper much flattened, 

 their septa horizontal; terminal cell small; an inconspicuous trun- 

 cate hyaline projection arising near the trichogyne. Spores 28- 

 30 X 3 ft. Perithecia 100 X 35-40 /i. Basal cells 40-50 p. Total 

 length to tip of perithecium 150 p.. 



On Haliplus ruficollis and Cnemiolottis muticus, Connecticut. 



Occurs rarely on the right elytron of its host, usually upon Hali- 

 pbus, a single specimen only having been found on Cnemidotus. 

 It is distinguished from all other species by the three superposed 

 basal cells of the receptacle, the upper of which appears to be what 

 is usually the middle of the three cells which normally form the 

 base of the perithecium. The inflated, abruptly papillate perithe- 

 cium is also a distinguishing character. 



Heimatomyces lichanophorus, nov. sp. 



Hyaline except for the suffused basal cell. Perithecia bent out- 

 wards at an angle from the basal part of the receptacle, tapering 

 slightly to the papillate apex. Basal cell of receptacle enlarged 

 and greatly elongated, more or less intensely blackened above its
