work has the appearance of being well done; but its aim is purely 
systematic, and the point of view is that of a generation ago, when, 
much more generally than now, the object of the student was to 
label the specimens in his collection and to arrange them in an 
orderly manner. C 
Revision of the Melanopli.! — This is a monograph of that division 
of the Acridiidæ or short-horned grasshoppers which includes our 
common red-legged locust, the Rocky Mountain locust, and other 
well-known forms. The group includes thirty genera (eighteen new) 
and 207 species, of which 115 are here described for the first time. 
As the work is done in that thorough manner which is characteris- 
tic of Mr. Scudder’s monographic work, it is obvious that this is an 
exceedingly important contribution to our knowledge of the orthop- 
teran fauna of North America. One cannot go over the pages of 
the book before us without being impressed with the devotion of the 
worker, as shown by the infinite care and patience with which the 
descriptions have been made. E 
Handlirsch’s Monograph of the Phymatidæ; Fernald’s Ptero- 
phoridæ of North America. — Handlirsch’s “ Monographie der Phy- 
matiden” (Ann. k. k. nat. Hofmuseums, 1897, Bd. xii, No. 2, pp. 127- 
230, taf. 4-9) is a well-planned and well-executed systematic study. 
The work of previous investigators is stated in sufficient detmi, snd 
there are brief notes relating to the morphology, anatomy, d 
life-habits, geographic distribution, systematic position, and relation- 
slips of the family. The tabular separations of the subfamilies, 
genera, and species, and the descriptions of the genera and species 
are clear and concise ; three new genera and twenty-eight new species 
are described. Handlirsch recognizes three subfamilies, the Phy- 
matin, Macrocephaline, and Carcinocorine ; of Phymata, the only 
genus of the Phymatine, there are twenty-five species, two from 
Europe and the others from North and South America and the West 
Indies. Four species are noted from America, north of Mexico, and 
of Phymata erosa, the well-known ambush-bug, many subspecies, 
ranging from Canada to Chili, are described. Scott’s two species 
from New Zealand are doubtfully placed here. There are six genera 
and forty-three species of Macrocephaline; thirty of the latter are
