THAXTER. MONOGRAPH OF THE LABOULBENIACK.K. 2S7 
Female individual, colorless. Primary receptacle consisting of four supcrpoxd cell terminal 
one acuminate; the subbasal giving rise to a branch which produces a single se uiilary reeeptad. , mad

perithecium. Perithecium erect, bent inward toward the seta on which the individua] grows, the u i- 
ous portion hardly, or not at all, inflated; the distal portion curved outward, tapering to the point tp , 
which is subtended on the inner side by a stout, bluntly rounded projection alxnit a> long a the fn « 
apex of the perithecium, which extends outward at right angle- from its base. Total length to tip of

In the conformation of its perithecial tip this species resembles //. Zmzilxiri?ius mote nearly than 
any other species. The perithecial appendage or subterminal proce is, however, blunt orevi n slightly 
enlarged distally. The host is a large wingless roach, species of which are very common in Florida 
but although, through the kindness of Professor Rolfe, I have had an opportunity to look over MUiimiu.s 
specimens from Miami, I have been unable to discover any parasites on them.
