titled ‘‘ Fungi parasitic on Aleyrodes Citri.” He also described 
a new species of “‘ Microcera,”’ but did not name it. 
In 1909, Saccardo added a new European species of Micro- 
cera, M. curta, from Germany; and, in 1912, Patouillard de- 
scribed Microcera Tonduzi from Costa Rica. 
Miyabe and Sawada gave an account of the fungi parasitic 
on scale insects in Formosa in 1913. They referred the common 
Japanese species to Sphaerostilbe coccophila, with considerable 
doubt. A Microcera which belongs to Parkin’s second group 
was named Microcera Fujikurot. Ophionectria coccicola was re- 
corded, and a new species, Ophionectria tetraspora, was described. 
Sawada subsequently (1914) published, in Japanese, a paper 
on “Some Remarkable Parasitic Fungi on Insects found in 
Japan.” The only species mentioned which is relevant to the 
present subject is a new species of Fusarium, Fusarium Aspi- 
diott, on Aspidiotus perniciosus. 
In 1913, H. and P. Sydow instituted a new genus of Sphaeria- 
ceae, Coccidophthora, parasitic on scale insects, on a specimen 
collected by Hara in Japan, the species being named Coccido- 
phthora variabilis. In the following year, however, Hara stated 
that the specimen submitted to Sydow consisted of two fungi, 
a Nectria parasitic on a scale insect, and another ascigerous 
fungus parasitic on the Nectria. Hara named the Neciria, 
N. variabilis, and instituted a new genus for the super-parasite, 
which he named Philonectria variabilts. 
In 1914, H. and S. Sydow described Microcera Merrillti on 
a scale insect from the Philippines. 
Stevenson, in 1917, described a Tubercularia on Lepidosaphes 
beck and Hemichionaspis minor, on Citrus in Porto Rico, as 
Tubercularia coccicola. 
The species of Nectriae, or their probable conidial stages, 
which have been recorded as occurring on scale insects are:
