USE OF SPOKOTRICHIUM GLOBULIFERUM. 47 
Ohio to be infected with the disease, consignments have come to me 
with the insects dying and others dead and covered with Sporotrichium, 
showing that this was already present and that the very utmost that 
we could expect to accomplish would be to aid in locally spreading the 
contagion. Besides this, I have sent material to farmers sufficient to 
start the fungus in their fields, knowing perfectly well that it would be 
a considerable time before actual benefits could by any possibility be 
expected to materialize, and within a week received the astonish in g 
information that the fungus was so perfectly successful that the bugs 
all disappeared within a few days after the application of the disease. 
I have no doubt but that the distribution of upward of 7,000 boxes of 
these fungi to the farmers of Kansas has accomplished a vast amount 
of good, but beyond this it is impossible to go. Of Professor Snow's 
laboratory work or the labors of himself and assistants in the fields no 
criticisms can be made, and I shall have occasion to quote from these 
in future pages of this bulletin. 
Sporotrichium globuliferum, or at any rate the fungus which is now 
passing under that name, was first found by Professor Forbes to infest 
the chinch bug in Illinois in 1887, and its destructive effects observed 
in the fields in the autumn of 1888. 
Since the last-mentioned date I have distributed upward of 3,000 
packages of this fungus to the farmers of Ohio during the outbreak of 
chinch bug in the State in 1895, 189G, and 1897, and know from per- 
sonal observation and study that it is under certain favorable condi- 
tions a deadly foe of this species, that its use under these conditions is 
practical, and that if its application can be made simultaneously with 
the commencement of the breeding season it will prove effectual. This 
statement is made for the reason that so late as 1895 Dr. M. C. Cook, 
in his popular work on entomogenous fungi, " Vegetable Wasps and 
Plant Worms" (p. 120), states that "no species of this genus is known 
to have occurred on living matter as they are saprophytes pure and 
simple, and then, probably, only as the stroma or conidiaof some fungus 
of higher organization, possibly the Splueriacei.'' This statement was 
made in discussing JS. densum, but on the following page (121), after 
dealing with S. glob ulifer inn, he appends the following paragraph: 
"The remarks made under the previous species are applicable to this, 
which is not entitled to rank as a parasite, but rather as an accidental 
development upon one out of many forms of decaying animal matter/' 
Other insects attacked by Sporotrichium globuliferum. — Spegazzini* 
described the species from Argentina as occurring on the dead bodies 
of beetles, notably Monocrepidius and Naupactus xylanthographus. 
Besides Parandra brunnea, Professor Forbes has recorded this fungus on 
Lachnosterna, while 1 have infected, artificially, Epicauta pennsylvanica 
and witnessed an instance of accidental infection oi' MegiUa maeulata. 
In both cases these beetles were almost entirely covered by the fungus
