402 General Notes. [ May, 
Bag-worm ( Thyridopteryx ephemereformis). This immunity en- 
joyed by the China tree from the attacks of insects, is not per- 
fect, however, as we have recently received from Alabama some 
twigs and leaves infested with the scales of a Coccid belonging to 
the genus Lecanium; but what is more interesting, the twigs 
are covered with the waxy scales of a Ceroplastes of really 
beautiful appearance and new to science. The leaf-cutting ant 
(Atta fervens) shows a decided partiality for the leaves of this 
tree in Texas. 
GaLts on Eucatyprus.—Mr. R. McLachlan has recently de- 
scribed two very interesting galls occurring on Eucalyptus gracilis 
in Australia; the one a curious modification of a flower bud and 
possibly Cecidomyidous, the other occurring on the leaf-stem 
and looking like a capsule with three or four long arms, and sup- 
posed to be Lepidopterous. We know of no Lepidopterous galls 
that take on any such specialized characters as the last named, 
figured by Mr. McLachlan, the galls made by this Order of insects 
being almost invariably mere swellings of a stem, a fact which 
would indicate that the Lepidopterous larva which Mr. McLach- 
lan found in this Eucalyptus gall might be inquilinous. 
Nortu AMERICAN ANTHOMYIAD&.—Dr. Hagen publishes in the 
March number of the Canadian Entomologist, a list of the North 
American species of this family of flies, contained in the Cam- 
bridge Museum, and which have been examined by Mr. R. H. 
Meade of England. In Osten Sacken’s Catalogue there are 139 
species given, including a number of Mr. Walker's, which seem 
not to have been yet identified. Mr. Meade makes out 121 spe 
cies, and Dr. Hagen states that Loew’s collection contains 12 not 
seen by Mr. Meade, so that the whole number of North Ameri- 
can species, represented in the Cambridge Museum, is 133, of 
which 34 seem to be identical with European species. a 
thomyia angustifrons Meig., of the First Report of the United States 
Entomological Commission, which so commonly infests, in the 
larva state, the egg masses of Caloptenus spretus,is referred here 
as in Osten Sacken’s catalogue to the genus Chortophila Macq. 
GALLs AND GALL-INSECTS.—We are -pleased to see, that after 
some years of intermission, Mr. H. F. Bassett, of Waterbury, 
Conn., continues his descriptions of North American Cynipide. 
He describes in the above-named journal, several Californian 
species, among others C. g. californica, which attains the largest 
size, with perhaps one exception, of any hitherto known “0 
American gall. The flies produced from it are all females, but the 
gall is interesting to the Coleopterist because it nourishes ye 
nathus cornutus Lec., a beetle very curious from the fact that the 
male has a long, erect horn on the base of each mandible, the wid 
nearly meeting at their incurved tips. Mr. Bassett describes his galls 
from specimens collected in 1878 and 1880, at Red Wood city,
