North Ameridan Ceutophili.—This interesting group of wing- 
less locustarians has been monngraphed in a very satisfactory manner 
by Mr. S. H. Scudder.’ “ With the exception of the genus Troglophi- 
lus Krauss, with two species from European caverns, and the genus 
Talitropis Bol., with a single species from New Zealand, placed respect- 
ively at one and the other end of the series, they are known only from 
America; and with the further exception of Heteromallus Brunner, 
with two species from Chili, they are all peculiar to the United States 
and Northern Mexico. Here they include six genera and sixty-seven 
species, the genus Ceutophilus al taining above fifty species. 
larger proportion of them, if not all (excepting Udeopsylla nigra) fre- 
quent dark places, such as burrows, pits, caverns, wells, hollow trees, 
and especially the crevices beneath fallen logs.” Thirty-eight new 
species are characterized in the present paper, in which the treatment, 
except for the absence of illustrations, is all that could be desired. 
The Plume Moths.—A study of the biological relations of the 
earlier stages of the plume months convinces J. W. Tutt’ that these 
insects belong to two distinet families, the Pterophorina and the 
Alucitina. The latter (called Orneodine by Fernald and others) “be- 
long to the Pyraloid section of the Obtect:e, the larva of which has a 
complete circle of hooks to the ventral prolegs, and the pupa of which 
is smooth and rounded, laterally solid, inner dissepiments flimsy. The 
free segments in both sexes are the fifth and sixth abdominal. 
“The Pterophorina belong to the Incomplete and have no affinities 
with Alucitina. Both groups have under the same or similar necessi- 
ties developed plume wings and this is the only connection. The pupa 
is attached by a cremaster, less solid and rounded, appendages often 
partially free. Free segments may extend up to the third abdominal." 
In emphasizing the necessity of biological studies in classification, 
Mr. Tutt quotes with approval, the recent dictum of W. H. Edwards: 
“There never will bea final authoritative revision of any genus of 
butterflies till the preparatory stages in every species of it are 
known."
