usual elsewhere as soou as wings are obtained, a meadow is not 

 attacked throughout at the same time, but the bugs appear to move in 

 compact bodies, and one may see the uninjured portion clearly defined, 

 the edge taking on a slight tinge of yellow, then yellowish brown, 

 followed by the thoroughly browned and dead grass, all within a space 

 little more than a yard in width and stretching away in an irregular 

 course across the field, in much the same manner as is to be witnessed 

 when bugs migrate from a wheat field to an adjoining cornfield in 

 other portions of the State. 



So far as temperature is concerned, this portion of Ohio belongs with 

 northwestern Pennsylvania, western New York, and the southern half 

 of Ontario, Canada, an area over which the chinch bug is supposed to 

 be comparatively rare, even southern Michigan and northern Indiana 

 being so far exempt from its ravages. This wonld place northeastern 

 Ohio on the extreme northern border of the species, 1 and lead us to 

 suspect that if it ever does break out in Canada in destructive numbers 

 it will be found to ravage the timothy meadows more than elsewhere. 



I have always held to the opinion that the parasitic fungus Sporo- 

 trichum globuliferum could only be used in a manner to offer relief to 

 the farmer during wet seasons, and where there was a superabundance 

 of the host insect, and though I have been severely criticised, am of 

 this opinion still. For years I have been waiting such a combination 

 of conditions, as they do not often occur owing to the fact that wet 

 weather during the hatching season is fatal to a large per cent-of the 

 young, and not until the present year have my hopes and desires in 

 this direction been gratified. To learn that a measure will fail under 

 adverse conditions is but half satisfactory, and before one can feel at 

 all satisfied the same measures must be tested under favorable condi- 

 tions. This year I can say that, with all conditions favorable, Sporo- 

 trichwm globuliferum has done all that Professor Snow or any other 

 entomologist has claimed for it, but under conditions as adverse as 

 these have been favorable the results will prove quite the reverse. 

 While I do not find any reason for the immunity from attack this year 

 over the area where this fungus was distributed last year, believing 

 that this can be accounted for by peculiar meteorological conditions, it 

 saved farmers thousands of dollars where it was used the present 

 season. Where applied early in June, though it did not save the wheat 

 crop, it did in many cases so reduce the number of bugs before they 

 had advanced far into the cornfields that they were rendered powerless. 

 In wheat fields, where an early application was made, the furrows and 

 other depressions in the surface were soon white with diseased bugs, 



a Since the publication of my paper in Jour. Cinn. Soc. Nat. Hist., Vol. xvm, Feb., 

 1896, and later, and revised in Bulletin 69, Ohio Agricultural Experiment Station, 

 Mr. W. H. Harrington informs me that he has a specimen taken by Dr. Fletcher, in 

 Winnepeg, and that he has himself collected it along the seashore almost on the 

 boundary line between New Brunswick and Nova Scotia.
