Entomophthora calopteni Bessey.—The original description of this species appeared 
inthe American Naturalist for December, 1883 (page 1280). Itis reproduced here 
verbatim: 
““T. Empusa stage, not seen. 
“II. Tarichium stage : Oospores globular, or from pressure somewhat irregular in 
outline, colorless, 36 to 39. in diameter; walls thick (4.), colorless, smooth ; pro- 
toplasm granular, after as if composed of many small cells, often with a large round 
vacuole. Occurring as a clay-colored mass {n the body cavity and femora of Calop- 
tenus differentialis. 
“Ames, Iowa, August and September, 1883.” 
Specimens of this fungus collected in Wisconsin by Trelease and Seymour were 
distributed under the name given above by Ellis and Everhart in North American 
Fungi, No.1801. In April, 1888, Mr. Roland Thaxter published, in the Memoirs of 
the Boston Society of Natural History, an important paper on The Entomophthorx 
of the United States, in which he revises the species of the group, and adopts the 
older generic name Lmpusa, first proposed by Cohn in 1855, in preferenceto Ento- 
mophthora proposed by Fresenius in 1856. Moreover, Mr. Thaxter concludes that the 
fungus described above is identical with one described as Entomophthora grylli, by 
Fresenius, in 1856. Specimens of this species were distributed in 1885 by Dr. Farlow, 
in Ellis’ North American Fungi, No. 1401. Our species thus appeared in Mr. Thaxter’s 
paper under the name of Hmpusa grylli (Fres.) Nowakowski.
