cell of the conidiophore, from which arise from two to five long, 
lanceolate arms. There are usually three arms, and the whole 
conidium resembles the print of a bird’s foot. It has been stated 
that the arms close up when the conidium dries, and expand 
again when it is wetted, so that the spore is propelled along 
the surface of a leaf, but I have not been able to observe that 
effect. 
In 1902, Hennings* found a similar conidial fungus on scale 
insects on orange from Brazil and instituted for it a new genus, 
with the species Tetracrium Auranti. Later, von Hohnelf re- 
examined Henning’s specimen and discovered perithecia on it, 
of the same structure as Ophionectria coccicola. But he placed 
his species in the genus Puttemansia and transferred Ellis and 
Everhart’s species to the same genus. 
In rg10, Masseet described a scale insect fungus from 
Trinidad as Scleroderris gigaspora. No type specimen is avail- 
able, but it is agreed that this was Ophionectria coccicola. 
In 1913, Miyabe and Sawada§ described Ophionectria tetra- 
spora on Parlatoria from Formosa. I have examined a specimen 
of this from Formosa, and it appears to me to agree with 
von HGhnel’s description of Puttemansia Aurantu, but I have 
not seen the type of the latter. 
A third species, co-generic with Ophionectria coccicola, has 
recently been found in Ceylon. 
Puttemansia Aurantii is at present known only from Brazil 
and Formosa. Ophionectria coccicola is a widely distributed 
species, and I have seen specimens from Ceylon, Formosa, 
South Africa, Florida, and Dominica (W.I.), while it has been 
recorded correctly from Java. These species have occurred on 
scale insects belonging to the genera Parlatoria, Aspidiotus, 
and Lepidosaphes (Mytilaspis). 
Ellis and Everhart placed their species in OpMonectria. 
Seaver transferred it to a recently-instituted genus, Scoleco- 
nectria\|. Von Hohnel considers that it belongs to Puttemansia, 
which is a genus founded by Hennings for a fungus he thought 
was a Discomycete. Consequently the nomenclature question 
has become somewhat complicated. It will be discussed fully 
in a later paper. But the three species of Ophionectria, Scoleco- 
nectyia, or Puttemansia which are parasitic on scale insects 
agree with one another in having a Tetracrium conidial stage. 
Consequently, as far as these species are concerned, the simplest 
way of escape from the maze of nomenclature is to institute
