This species was found growing on the abdomen of a single specimen of its host, examined 
In the collection of the Museum of Comparative Zoology. It seems to be sufficiently dis- 
tinguished from the succeeding species by its olive brown color and very differently shaped peri- 
theciuni. Tlic fourteen type specimens show no variation from the form represented in the 
plate.

Peritlieciura short, stout, straw-yellow, outwardly inflated, the inner margin nearly straight, 
the distal portion conical, its apex bluntly pointed; stalk-cell long, nearly cylindrical, distally
