vious years had but had a knowledge of entomology, who knows what 
might have been saved. ‘ 
The Twentieth Report shows the same painstaking care in its prepara- 
tion that have characterized its predecessors. It has as a frontispiece 
a half-tone portrait of the author’s sister, Miss Georgiana E. Ormerod, 
who so long collaborated in the entomological work, and who died dur- 
ing the year. American entomologists generally have felt much sym- 
pathy for Miss Ormerod in this loss and will read with interest the touch- 
ing tribute in this report. 
A large number of insects are treated of by the author of the report, 
and several new illustrations embellish its pages. 
Lepidoptera.—Under the names Ptilodontidæ and Melalophide, 
Mr. Harrison G. Dyar’ has made a generic revision of the North Ameri. 
can, European and Indian members of that group of moths until recently 
known as Notodontidæ. Heseparates the two groups or families on lar- 
val characters. The lowest genera (e. g., Gluphisia) present “smooth 
larva with simple sets ; others have variously humped or otherwise mod- 
ified bodies. Then follows a group in which the moths tend to lose the 
tongue although not sharply marked off by thischaracter. The larvae, 
however, are hairy, that is they have developed warts and secondary 
hairs. The wart formation is peculiar being characterized by three 
warts above the stigmatical wart on the thorax, and thus contrasting 
with the parallel wart formation in the Arctiid allies, another great 
branch of the Bombyces. At first all the warts are in line but soon we 
reach forms (e. g., Apatelodes) in which the central wart is moved back 
out of line. At this point a large group of moths in India, has diverged 
from the type losing one vein of the fore wings. These are the true 
Eupterotide and form the highest group of the Ptilodont allies. The 
line is, however, almost directly continued by the European genus 
Lemonia (frenulum gone) into the Lachneide (cubitus 4-branched), 
the larva remaining true to type but becoming gradually more special- 
ized to culminate in the Lachneids.” The Eupterotide are not treated 
of in the revision. As may beseen the first division is much the larger, 
but the second contains such well known forms as Datana, Melalopha 
(Ichthyura) and Apatelodes. ;

Sciences, has just published in an octavo pamphlet of 96 pages and six 
admirable plates, Prof. J. McNeill’s Revision of the Tryxalinz of North
