1894.] Entomology. 1053: 
Phenacoccus is rich in Palearctic species, there being eleven or 
twelve, several recently (1886-1891) described. In strong contrast, 
we have but two endemic nearctic species, both western. There is not 
one from the neotropical region, but Australia furnishes two and New 
Zealand one. 
Ripersia has five Palearctic species, three from New Zealand and one 
from Australia. It was thought that we had none in America, but 
Mr. N. Banks has discovered a most remarkable maritime species, the 
deseription of which now awaits publication. It is very closely allied 
to one (R. rumicis) from New Zealand. 
Coccus has three races, perhaps not very distinct as species, from the 
warmer parts of North America, extending northward in the Rocky 
"Mountain Region. C. agavium may be referred to a distinet genus, 
Gymnococcus of Douglas, which should be added to the list of mono- 
typic genera above. Its native country is unknown. 
Kermes has several Palzarctic species; one Ethiopian, not yet de- 
seribed ; one Australian; and a problematical number nearctic. In 
the last mentioned region only a single species has been deseribed, but 
others exist and sorely need attention. No species are neotropical. 
Orthezia is doubtless an old form, and certainly a very interesting 
one. The number of Palæarctic species is a matter of dispute, but 
there are not over half a dozen. Four are nearctic; and here it may 
be mentioned that Prof. C. H. T. Townsend has just discovered a beau- 
tiful new one in Sonora. ‘Two are neotropical, both described by 
Douglas. None were known from the Oriental region, until the other 
day Buckton described one from Ceylon. Not one occurs in Australia 
or New Zealand. 
Prosopophora was described as lately as 1892, but already we know 
four species, one neotropical, one nearctic (New Mexico), and two 
from Australia, 
Tachardia has four American species, one still awaiting publication. 
There is, also, one from the Oriental region, while three are Austra- 
ian 
Pulvinaria is'rich in Palearctic species, but the endemic nearetic spe- 
cies are only three or four! Four are neotropieal; two (one unde- 
seribed) Oriental; four Australian; and one is from the Sandwich Is. 
'The absence of native species in New Zealand is noteworthy. 
Ctenochiton, with eleven species, and Lecanochiton, with two, are 
strictly confined to New Zealand; and may be set off against the nu- 
merous extraordinary gall-making forms of Australia, which are want- 
ing in the New Zealand fauna.
