length of the abdomen, the head and thorax taken together being 
more than twice contained in the abdomen, while in J. Saussurit 
they are two-thirds as long as the abdomen. The 8th abdominal 
segment, also, is nearly twice as long as in the Mexican species. 
The head is broader than in J. Saussurii, but narrower and pointed 
a little more than in J. solifugus. The forceps are much nearer J. 
solifugus than the Mexican species, and is much longer than in either 
species. Length -58 inch; the Mexican specimen measured about 
an inch. It is whitish, with the two terminal segments honey yer 
low; the forceps much darker. We shall in a succeeding number 
figure this interesting form, which is of extraordinary interest, as it 
is an ally of Campodea, now regarded as a stem-form of the higher 
insects by Brauer, Lubbock and others.— A. S. PackarD, Ji. 
Tue “ HATEFUL” GRASSHOPPER IN New Encranp.—Thongh the 
ravages by grasshoppers in New England are caused by the red- | 
legged locust (Caloptenus femur-rubrum), it seems that for several , 
years there have been specimens of Caloptenus spretus from Maine 
and Massachusetts in the Museum of the Peabody Academy of 
Science. They have been hitherto confounded with C. femur-rib l 
rum, but are at once distinguishable by the shorter male cerci and 
fhe notched terminal ventral segment. The interesting fact about 
these eastern C. spretus is, that they are of precisely the same FE ; 
and markings of C. femur-rubrum, being much smaller and with 
much shorter wings than the western race, a difference i : 
due almost wholly to climatic causes. A number of surmises ed 
garding sexual and natural selection and mimicry might be y : 
dulged in, but the facts that might suggest them can be exp uh 
by a reference to the different meteorological conditions by r w 
the two races are environed. In Dr. Hayden’s forthcoming Er : 
nual Report on the Geology of Colorado,” the reader will form a 
number of facts bearing on the variation in size of body, and 10% 
of wings and color in eastern and western examples 43 ihe 
species of moths, the conclusions from which are borne out by 
study of these grasshoppers.—A. S. PACKARD, Jr.
