winged forms. The former had short antennse and 
short legs, and he considered that they were the 
males. Kevertheless, he says he never saw any union 
with the other members of the company. 
Late in autumn I found associated with the apterous 
females of this species a small Aphis with dispropor- 
tionately long wings and antennae. Its general 
colour was of a reddish-green, and the apex of the 
abdomen was furnished with two papillae, which in the 
males of Aphis constitute the valves attached to the 
generative organ. Unfortunately, although this insect 
was carefully drawn, its special anatomical examina- 
tion was omitted. Nevertheless, there can be no 
reasonable doubt that this insect, figured in Plate Ilf, 
is the male of Siphonophora rosce. It closely agrees 
with the better known males of other species of this 
genus. 
Kaltenbach does not appear to have met with the 
male. This specimen is the only one that has come 
under my notice.

Long oval. Ferruginous red. Head broad, with a 
light streak passing from the vertex to the occiput. 
Byes red and large. AntennaB remote at their bases, 
about one third the length of the body. The relative 
lengths of the joints differ from those shown in the 
other stages of metamorphosis. The cornicles and 
legs also are relatively shorter. The hind tibia© are 
furnished with numerous tubercular spots, which 
probably assist the insect in arranging the soft and 
glutinous eggs in the recesses of the leaf-buds. All 
the limbs are either of a dark-olive or black colour. 
The eggs are at first yellow, but subsequently they 
become black by reason of certain changes shown by
