bodies of their fellows. This must be carefully watched and guarded 
against, as well as the accumulation of weeds, sticks, or other trash 
along the outside of the field. If the ground next to the fence and for 
8 or 10 feet outside is made smooth and level, and a harrow, plank drag, 
field roller, or any other apparatus that will kill the crickets, be drawn 
at intervals of from one to three or four times a day over the wriggling 
mass along the border, thousands would be killed and injured, which 
the others will proceed toe devour in short order. 
This has been tried with very satisfactory results by the Orchard 
Farms Company at Bisuka and by farmers near Bellvue and at other 
places. 
Some success has been had in herding and driving them off, causing 
them to pass to one side of a farm coming in the line of their march, 
but the plan is not so successful, as it takes a large force and occupies 
several days and is only applicable early in the season while the crick- 
ets are young and active, since, when they acquire their full growth 
and begin egg laying they are more sluggish and travel much slower,

A.—REPORT BY D. W. COQUILLETT. 
On the 1st of August I examined the lemon and orange trees in the 
grove of Col. J. R. Dobbins, where about one dozen specimens of Orcus 
chalybeus were placed in July, 1892, but found no trace of this insect in 
any of its stages. I learned from Col. Dobbins that a short time after 
placing the insects on one of the trees they disappeared, and he had 
not seen a trace of them since that time. 
I next visited the orange and lemon grove of Mr. A. Scott Chapman, 
at which place about 150 specimens of Orcus chalybeus were liberated in 
the month of July, 1892, but a careful examination of a large number 
of the trees failed to reveal a single specimen of this insect in any of its 
stages. Mr. Chapman informed me that his experience with these 
insects was the same as that of Col. Dobbins; the insects disappearing 
shortly after bemg liberated and no trace of them having been found 
since that time. 
The following day I examined the orchards in Orange County, where 
some of the imported insects had been liberated. Mr. H. K. Snow, of 
Tustin, had received and liberated on one of his orange trees about forty 
specimens of Orcus chalybeus and two of Leis conformis; this was in 
February, 1892, but I was unable to find a trace of them after a long 
search. Mr. S. W. Preble had received and liberated several specimens 
of Orcus chalybeus in February, 1892, but not a trace of them could be
