other insects. By devouring these, as they do in great numbers, 
they are beneficial to the agriculturist and should be recognized as 
such. This particular species, however, has taken to vegetable 
food, and as it preys upon some of our most important crops and 
is increasing in abundance every year, it is likely to be a serious 
pest unless an effort is made to check it. The beetles above 
referred to are commonly known as lady-bird beetles and scien- 
tifically as the Coccinellide. 
_ The eggs are deposited in patches on the under side of the leaf 
and are easily recognized by their bright yellowcolor. Thelarve 
are slug-like in appearance, yellow in color and have black, 
branching spines. The beetles average nearly three-eighths of an 
inch in length, are almost as broad as long and very convex. In 
color they are bright yellowish brown, but have four black spots 
on the, thorax and seven on each wing cover (elytron), two of 
which are situated on the suture where | 
the wing covers join. Fig. 1 represents the 
adult. | 
The eggs hatch in about 12 days. 
The larve feed on the under surface of the 
leaves but do not eat clear through, while 
the adults feed on the upper surface, eat- 
ing off the outer portion in semi circular 
patches. The injured portion of the leaves 
soon wither, indicating where the insects 
have been. I have been unable to ascertain thus far how long 
the larvee feed and remain in the pupastate in this vicinity. Mr. 
Falconer, of Glen Cove, says that the beetles appear in that vicin- 
ity very suddenly, and usually in great numbers, doing consider- 
able damage, especially to squash and pumpkin vines. They are 
first seen apout the latter part of June. During the winter they

. Early in summer they should be carefully watched for and 
promptly dealt with. Fortunately these insects feed openly, andas 
- they devour the tissue, the application of poisons, such as Paris 
* green or London purple, will have the desired effect. Either of
