Pear (Pyrus communis) , quite numerous on young leaves in June, causing them to

tree in the Insectary of the Department during November. 
European Dogwood (Cornus mas), very numerous during October and November, 
curling the leaves. 
Orange (Citrus aurantium and other varieties), in the orange house of the Depart- 
ment of Agriculture, very numerous on young leaves and shoots at almost any time

They were also found, to be extremely numerous on many hot-house 
plants, particularly so on Hydrangea and. Begonia; considerable num- . 
bers were also observed upon the leaves of the Jamestown weed 
(Datura stramonium) growing in the Insectary of the Department. 
It will be seen from these notes that this particular species is not 
alone a very general feeder, but that it has also a very extensive dis- 
tribution.

diameter across the abdomen, about 0.6 ram . Abdomen pyriform; antenna? rather 
short and slender, reaching to or beyond the middle of the abdomen. Nectaries 
about twice the length of hind tarsi, conico-cylindrical. Rostrum rather stout, 
reaching nearly to third coxse. A prominent conical aud fleshy lateral tubercle may 
be observed each side of the prothorax and behind the nectaries, and four smaller 
ones each side of the abdomen in front of the nectaries.

yellow or different shades of green to black, frequently marked with irregular 
darker shadings; this variation in color is, however, often as pronounced in the 
different younger stages. Eyes dark brown. Antennas whitish or pale yellowish 
with the apex of the sixth aud the last joint black, legs white or pale yellowish; 
the coxse, apex of tibia, and the tarsi, dusky or black. Nectaries black ; tail greenish

to orange or reddish-brown, though in some cases they are of a beautiful, pale, 
bluish-gray. Head and prothorax dusky; the meso- and metathorax either 
whitish, yellowish, or glaucous green, frequently marked with two faintly dusky 
medio-dorsal stripes. Wingpads and nectaries black ; the rest as in the apterous
