issued was to be seen. Adult Tachinw were also observed in the in- 
fested fields. 
Some of the dead grasshoppers had the appearance of having been 
affected with Entomophthora,and I gathered a number in order to make 
an effort to cultivate the disease, but as yet have nothing to report in 
this line. The dead hoppers will be kept with living ones, and if the 
latter take the disease we may hope to still further multiply the dis- 
ease by inoculating still others, and then an effort can be made to dis- 
tribute the disease in the fields. Its spread, however, is evidently — 
slow, and Ido not think other measures should be neglected this season 
for a plan which is still uncertain. — 
Among the natural enemies observed, toads were perhaps the most 
common, some of the fields containing great numbers of them, espe- 
cially of half-grown individuals, and these would seem capable of greatly 
reducing the numbers of hoppers. A dead one, which saved me the 
necessity of making a dissection to get positive proof, showed in the 
partly decomposed stomach the legs and other parts of grasshoppers, 
proving that, as would be inferred from presence of toads in the fields, 
their mission was to feed uponthe grasshoppers. 
The attacks of skunks upon grasshoppers, as stated by Mr. Long- 
streth, have already been mentioned. 
As the tendency is for natural enemies to multiply with the increase 
of any species of insect, we may look for increased assistance from this 
source by another year, ard in connection with the measures already 
urged, these ought by another year to keep the insect entirely within 
the limits of destructiveness. 
Mr. Osborn then read the following paper: 
THE CLOVER-SEED CATERPILLAR. 
(Grapholitha interstinctana Clem. ) 
By H. OSBORN and H. A. GOSSARD, Ames, Iowa. 
On the evening of the 23d of May many small dark brown moths were 
noticed flying about a clover field upon the College Farm. They were 
resting upon the blossoms and among the leaves, and upon being dis- 
turbed would fly a few paces and then settle again. These moths 
proved upon examination to be Grapholitha interstinctana Clemens, the 
parent forms of the Clover-seed caterpillar mentioned in the Entomolo- 
_gist’s Report to the Commissioner of Agriculture in 1880. We had 
during the past winter received specimens of clover seed which we 
suspected of being damaged by this pest, which has been reported-as 
jnjurious in some of the states east of us in the last year ortwo. The 
moths are also remembered as occurring at Ames in numbers some eight ~ 
or ten years ago. They were not, however, at that time connected with 
any damage observed in clover fields.
