NOTES ON CEYLONESE APHIDES.

T HROUGH the kindness of Mr. E. E. Green, of the Botanical 
Gardens of Peradeniya, I was able to examine a few 
Ceylonese Aphides, amongst which I found very interesting 
forms. 
Of the species, four in number, which, according to the wish of 
Mr. Green, I here describe, two are new to science : Ceratopem- 
phigus zehntneri and Lachnus Greeni; the others are already 
described forms : the Siphonophora artocarpi of Westwood and 
Oregma bambusce of Buckton. As was already to be seen on the 
figures given by Westwood in the Trans. Ent. Soc., Lond., the first 
is not at all a Siphonophora, nor even a Siphonophorid (Macrosip- 
hid). As to Oregma bambusce , B., it is a very peculiar species, 
the description of which, however, is very insufficient, and the 
figures, in the Ind. Mus. Notes, rather fantastic ! 
GREENIDEA, n. g. 
For the reception of the Siphonophora artocarpi of Westwood 
it seems to me necessary to erect a new genus, which I take much 
pleasure in naming Greenidea. This may be characterized as 
follows :— 
“ Body elongate, furnished with numerous strong bristles on the 
whole upper surface, including the cornicles : these very long, 
nearly cylindrical, slightly constricted at base. Cauda very 
short, but well marked. No frontal tubercles, vertex nearly plain. 
Antennae six-jointed, the sixth joint furnished with an appendix 
longer than basal part. Anterior wings with the cubitus twice 
forked ; second oblique vein peculiarly -> curved ; posterior 
wings with two oblique veins removed at base ; wings carried 
vertically at rest.” 
Greenidea will be easily separated from the other genera of 
Aphidinae by the strong bristles which cover the body and corni¬ 
cles, and by the shape of these and the cauda.
