THE SPECIES OF NEMOBIUS FOUND IN NORTH AMERICA. BY SAMUEL H. SCUDDECK, CAMBRIDGE, MASS.
In the Journal of the New York
Entomological Society for September,
1896 (Vol. iv, 13~. 99-1071, I published a paper on "The North American
species of Nemobius," describing eight
new species and giving a table for the
separation of the fifteen known species. After the printing but bcfore the publi- cation of the paper, and, therefore, too late for insertion therein, I received
from Professors Bruner and Cockerell
three additional new species, in de-
scribing which at this time I remodel
the earlier part of the table, "and pub- Iish it in a complete form, so as to in- clude all the species. Professor Bruner
also sends me an additional species,
apparently new, from Vera Cruz, but
as it is only represented by a male,
I refrain from describing it until the
female isfound ; it seems to be allied to N. cubensis.

BY W. S. BI.ATCItI,EY, INDIAXAPOI.IS, INDIANA. COLEOPTERA (Cont.)
Fifty-three species of this family are
known to occur in the coniity.
Rcpre-
scntatives of but twelve of these have
been taken during the winter months,

hillsides.
188, Momcepedius au~itzzs Hbst.
Very common in winter beneath logs
ancl mullein leaves on sandy hillsides.
