tion darker. Body of spore about 52-60 X 20 ju, the termination 

 65-70X8, the stalk 50-65 /x. 



On the superior tip of abdomen and wing of a small drosophilid fly, Bocas 

 del Toro, Panama (Rarer), no. 2525. 



This species is perhaps more nearly allied to M. repens and the succeeding 

 species. From the former it is distinguished by its 4 clearly defined functional 

 tiers, its much longer, slender, curved termination, and the absence of an ap- 

 pendage from the stalk; while from the latter it differs in its smaller size and 

 quite differently shaped spores. One other American species, also allied to' 

 M. repens, is known from Trinidad, but more material is desirable before it 

 can be described. 



Miliaria fasciculata, nov. sp. (figs. 28, 29). — Tufts compact, the 

 spores and rather numerous sterile elements arising from a usually 

 well defined black base; the stalks relatively long, the termination 

 relatively slender, and usually curved, but somewhat variable, the 

 body of the spore blackish brown, roughened by very irregula 

 intricate darker markings, the 4 functional tiers well defined, 

 relatively short, paler, and rather abruptly narrower than the 

 cells immediately below, of which two are usually flattened, and 

 one or both longitudinally septate; the cells above 3 or 4, the 

 lower usually septate. Body of spore 85-100X24-28 m, the stalk 

 100-210 /x, the distal termination 50-64X8 /z. 



On a dull brown drosophilid fly, no. 2749, Kamerun, West Africa. 



This species occurs on the wings, especially on the veins, of its host, a 

 rather large smoky drosophilid, several specimens of which have been found 

 to bear it. It is clearly separated from the preceding species by its greater 

 size and different shape. From M . Lonchaeana, which is the only other form 

 with which it might be confused, it is distinguished by the fact that the stalk 

 and distal portion of the spore are not roughened, as well as by its different form. 



Aposporella, nov. gen. — Mucedinaceous, aposporous, entomo- 

 genous, a well defined septate axis attached by a blackened foot 

 and bearing short branches at the septa, which separate short 

 undifferentiated segments distally that are constantly renewed. 



Aposporella elegans, nov. sp. (figs. 30, 31). — Axis stout, erect, 

 straight, or but slightly curved, tapering, simple, the superposed 

 cells but slightly longer than broad, hyaline, the black foot clearly 

 defined; the branches short, simple, one to several in an irregular 

 whorl from all but the terminal cells; somewhat appressed, or but
