THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
But why not have a London Com- 
mitlee or Congress of Lepidopterists, 
empowered to adopt one or other, or to 
give a third arrangement of their own ? 
Then let them print a ‘ Loudon Cata- 
logue of British Lepidoptera,’ to which 
we may hereafter conform as to specific 
numerals.

ENTOMOLOGY IN AMERICA. 
In No. 184, p. 13, we called attention 
to the doings of Dr. Clemens among the 
Transatlantic Micros. 
Dr. Clemens was so good as to send 
us a number of pupae of several of liis 
new species last October, and now, in 
the fulness of time, two small moths 
have made their appearance. 
One feels considerable anxiety about 
the proper location of the insects which 
have just emerged. Dr. Clemens con- 
structed for them a new genus, Asj)i- 
disca, and, on account of their gay 
colouring, applied the specific name of 
JSplendoriferella. But what are the 
affinities of this Aspidisca sptendorifer- 
ella P 
At a glance the insect is so like 
Cemiosloma scilella, or rather lustralella, 
that it might be taken for it. It is much 
smaller than C. scilella, and has only 
one black line in the cilia, which runs 
straight out at the apex. 
The insects being still on the setting- 
board, have not been microscopically in- 
vestigated, but at present we can see no 
eye-caps, — an essential difference from 
Cemiosloma. 
Dr. Clemens lately forwarded to us 
sketches of the venation of the wings of 
his new genera, and we are thus enabled 
to compare the venation of Aspidisca 
with those of C. Laburnella and C. sci- 
lella, which our readers will remember 
are not identical. 
With the venation in C. scilella we 
can see no resemblance in the American 
insect, but in the venation of C. La- 
burnella there is more similarity, yet 
still the differences are quite sufficient 
to separate the insects generically, if 
their other characters demand such a 
proceeding. 
The subcostal vein of the anterior 
wings, which in Laburnella emits two 
branches towards the costa, and then 
terminates furcate on the hinder margin, 
in Splendoriferella emits one branch 
towards the costa, then one towards the 
hind margin, its furcate extremity going 
to the costa and towards the extieme 
apex. The median vein, distinct enough 
in Laburnella, is in Splendoriferella en- 
tirely wanting. In the posterior wings 
we^see no perceptible difference, except 
that the median vein, instead of ter- 
minating in the apex (as in Laburnella), 
terminates on the costa in Splendori- 
ferella. 
Dr. Clemens describes the larva as 
“ without legs or prolegs,” and he tells 
us that “ it weaves a cocoon between the 
cuticles of its mine, and cuts out a small 
oval disk.” Here then we have analo- 
gies with Anlispila. 
It will strike many of our readers 
with astonishment that an insect should, 
as it were, combine the characters of 
genera so widely separated ns Cemiosloma 
and Anlispila ; but no doubt many 
astonishing things have yet to be learnt 
from the study of the transformations of 
Extra-European Micro-Lepidoptera. 
As probably but few copies of Dr. 
Clemens’ descriptive paper have yet
