ochre yellow beneath. Atthe time of the last molt the upper 
surface of the abdomen becomes more or less depressed and the 
fully-developed wings appear. Plate I shows the squash-bug in 
different stages of development. It may also be added that squash- 
bugs feed at night asa rule, coming forth from their hiding places. 
about dusk and remaining on the vines during the night. Dur- 
ing the day they usually hide on the under side of the leaves. 
Several broods appear during the season. Unhatched eggs were 
found on squash vines in a field at New Lots, L. I., as late as.

Remedies. 
“ An ounce of prevention is wortha pound of cure” in this case 
especially, for when squash-bugs once get well started in a field 
1t is almost impossible to get rid of them. Insecticides are as a 
rule of but little value. Poisons would be of no use as the insect 
does not bite the tissue but sucks the sap from beneath the surface. 
There are few odors more offensive than that emitted by this. 
“old timer sinner,” and a repellant that would drive a more 
respectable bug away will have little or no effect upon this one. 
So far as has been observed, those farmers on Long Island who 
have succeeded best in combatting this pest are those who do not 
allow any rubbish to accumulate on or near their squash fields. 
Clean culture is always embarrassing to the squash-bug. 
Several farmers have asked with regard to the value of kerosene 
emulsion, insect powder, etc., as remedies for the squash-bug. 
As before stated, insecticides and repellants are generally con- 
sidered of but little value in this case. However, the following 
account of experiments and observations may be of interest : 
Early in September a field of squashes in the vicinity of 
Brooklyn was found to be badly infested by this insect. 
The patch was a small one and nearly surrcunded by a dense 
growth of weeds and underbrush. A large rubbish pile in the 
immediate vicinity had evidently furnished shelter for the hyber- 
nating bugs during the winter. They had gathered there in great 
numbers and were found in all stages of development. The bugs 
had evidently commenced at the east end of the patch near where 
the rubbish pile lay, and had up to that time totally destroyed
