intensified and showing a tendency to blend. The larva is 
at first a uniform orange with black head, changing to a 
greenish blue ultimately, with four longitudinal stripes. 
Remedies —Against these caterpillars we applied success¬ 
fully, on July 26, the kerosene emulsion and Ongarth’s 
liquid tree protector. The latter is the more effective of the 
two, as it sticks to the foliage better, and, while killing when 
it comes in contact with the caterpillar, it also seems to ren¬ 
der the plant obnoxious to insect life. On the same date 
applied hellebore as a powder unmixed, and diluted one 
tablespoonful to two gallons of water. This was not nearly 
so successful as the others.

the false chinch bug (Nysius angustatus). 
This insect appeared in market gardens in this vicinity 
last June for the first time. It first appeared on radishes, 
clustering in large numbers in the shade of the leaves near 
the ground. It next attacked a field of turnips, showing a 
preference for certain varieties, but avoiding all varieties of 
the rutabaga. It also did some damage to cabbage and cauli¬ 
flower, but confined itself particularly to the two plants men¬ 
tioned. It bears a striking resemblance to the chinch bug 
proper. The latter, however, has a dark head and thorax 
and two conspicuous black spots on the front wings. The 
true chinch bug feed almost entirely on the cereals and 
grasses, whereas the species under consideration favors cru¬ 
ciferous plants, and is of a paler and more uniform brown 
color. 
Remedies —This is by far the most difficult insect with 
•/ 
which I have had to contend the past season, because of its 
rapid movements and great numbers. 
Applied the kerosene emulsion, diluting the latter with 
nine parts of water; also applied OngartUs liquid tree pro¬ 
tector, and hellebore, both as a powder and mixed with 
water. The first two are very effective whenever the liquid 
comes in contact with the insect, but owing to their vast 
numbers and ability to fly, only a small proportion of them
