bcr of cells corresponding to the number of branches which it bears, the partitions running 
obliquely downward and inward (fig. 27). In some specimens the basal cell of the receptacle is 
curiously modified in a fashion (fig. 28) similar to that referred to in connection with Comp- 
somijces verticiUatus ; but this hoof-lilve structure docs not appear to be either connected with 
any special position occupied by the plant or with any peculiarity of the host, and is much less 
frequent than the normal form. Many species of Philonthus appear to be subject to its attack, 
whetlicr they occur in moist or dry situations ; but the parasite rarely occurs in any great 
abundance on a single insect. A form allied to this, but in such poor condition that it cannot 
be described, was found on specimens of Bledius hasalis Lee, collected in Florida.

large, stout, inflated ; its upper inner margin bulging strongly, the short, fiat tip abruptly dis- 
tinguished, bent slightly outward, the tips of the lip-cells hyaline. Appendages consisting of an' 
outer and inner basal cell not clearly distinguishable, the outer producing several, Ihc inner

or hardly exceeding the tip of the pcrithecium. Receptacle short, sub-triangular, distally more

peculiar form of its pcrithecium, in which are produced great numbers of spores? The append- 
ages are almost invariably broken, and as no young specimens luive been exnmincd, their exact 
origin at the base has not been made out. The outer basal cell bears a branch terminally and 
from 
inner cell on either side. The basal cells, as well as the lower cells of the bran<-hes proceeding 
from them, are usually so deeply suffused that the structure is obscured. The base of the 
trichogyne is often persistent, as in figs. 16 and 18.
