the least verdure appears. At this time some are 
in the larvae state, and others in the perfect state. 
The larvae are long and of a faint yellow, and, 
when fully grown, neaidy the size which they 
attain in their winged state, which is very small, 
but may be well discerned with the naked eye, 
especially when upon flowers which are, in dry 
warm weather, numerously infested by them, both 
in the perfect and imperfect state. They are 
furnished with six legs, and the emago, or per- 
fect insects, have wings, which are very narrow, 
something longer than the body. They lie upon 
the centre of their back, so that the greatest portion 
of the body is uncovered by them. The two wings 
are divided a little, near their lower end. For 
some time after the insect attains to a winged state, 
it retains nearly its original colour, afterwards be- 
comes nearly black, and in all stages of its 
existence, except when dormant through the cold 
months, which time it is concealed in the earth 
or crevices of walls and trees. It is very quick 
in motion when the weather proves favourable. 
I believe that one pair ai-e the progenitors of 
several generations in one year. Their depreda- 
tions are commenced at the spring, and are 
continued to the end of warm dry weather, 
upon various plants, especially on the blossom. 
They will be very commonly found both in their 
perfect and imperfect state, partaking with the 
Red Spider. On mellow Cucumbers, Vines, Kid- 
ney Beans, and many other Plants too numerous
