of the State of Colorado, and the fear was expressed that Kan- 
sas, Nebraska and Missouri would be visited by an invasion of 
the Rocky Mountain locust (Melanoplus spretus) Under direc- 
tion of Professor Riley, Mr. Lawrence Bruner has visited the 
portions of Colorado from which rumors came. is report has 
just been received, and is of such a nature as to allay all fears. 
. The principal reports were from Salida, Rico, Cañon City and 
Pueblo. During his sojourn in the State he visited all points 
along the line of the Denver and South Pass R. R., between 
Denver and Leadville, and from Leadville followed down the 
every locality visited, from which grasshoppers were reported, it 
was found that the numbers had been greatly exaggerated, 
and in no case was the migratory species found. All reports 
arose from a rather undue abundance of native species, which are 
present every year, and most of which have their preferred food 
plants in the shape of wild growth and noxious weeds. 
MIMICRY OF A DRAGON-FLY BY A SUMATRAN BUTTERFLY.—By 
the margin of a small stream I caught Leptocircus virescens, which 
derives protection from mimicing the habits and appearance of a 
dragon-fly, in a crowd of which it-is often to be found. In form 
it reminded me of the European genus Nemoptera. It flits over 
the top of the water fluttering its tails, jerking up and down just

abdomens. When it settles on the ground it is difficult to see, 
as it vibrates, in constant motion, its tail and wings, so that a 
mere haze, as it were, exists where. it rests.—Forbes’ A Natural-

Mr. Carter also told me rae a caterpillar about two inches 
long, which lives within the thick leaves of the maguey or 
in Mexico, but in July, when it is often abundant. It is appa-

EntomoLocicaL News.—Among the more remarkable insects 
of Turkestan, reports H. Lansdell in Mature for May 21, is a 
Wingless saw-fly, related to the Selandrie. Affected by this 
ce of wings, the thorax undergoes important changes, and 
appears greatly swollen, and all the females generally have the 
appearance of little e bags. ——Among the Orthoptera of Turkes- 
are two species of locusts whose ravages have been com-
