certainly quite rare in American collections, and I know of no authentic 
record of its occurrence in flour or meal, or of its breeding indoors. 
In Europe it is recorded from France, Germany, Italy, and Bussia. 
Redtenbacher, who described this species as Margus obscurus, says that 
it is "very rare in beehives and under poplar bark." The larva i& 
probably subcortical, but nothing of the breeding habits of the species 
appears to be known. 
Mr. Schwarz has specimens taken June 26 and July 1 at Marquette 
and Eagle Harbor, Mich., all found on the shores of Lake Superior. It 
was also taken June 17, at Park City, Utah, at an elevation of about 
8,500 feet, by beating in the woods. Snow was still on the ground at 
this time. A single specimen was picked up in the neighborhood of 
Washington, D. 0. 
Very recently Mr. 0. P. Gillette sent us for identification specimens 
of this insect. In response to our inquiry relative to the source from 
which they were obtained, he writes that of the four individuals found 
all were taken separately in general collecting at Fort Collins, Colo. 
One was found under a board October 30, one while sweeping alfalfa, 
May 19, and the other two in June and July. It has also been recorded 
from New Mexico, Pennsylvania, and Hamilton and Ottawa, Canada. 
It is not known in Mexico and Central America. 
A glance at the above localities will show that the species has most 
often been met with in the North, and it is not impossible that it is 
indigenous in boreal Europe and America. It is certainly not tropical. 
Eeliocerus (Gnathocerus) cornutus Fab. is cosmopolitan in the broader 
sense of the term, but in North America appears to be somewhat 
restricted in its distribution. In the Californian region it is firmly 
established both indoors and, in the San Diego district, also under 
bark. The species is said to occur in New York, New Jersey, Louis- 
iana, and Alaska, but it is doubtful if it has obtained a permanent 
footing as far north as Alaska. The species is also known from Mexico, 
Guatemala, Brazil, and Chile on this continent, from New Caledonia 
and Hawaii, and is rather common in Europe, particularly in the south- 
ern portion of the continent. 
Echocerus maxillosus Fab., represented in the list at 55, from Brazilian 
exhibit, is recorded also from Mexico, Lower California, Guatemala, 
Nicaragua, Chile, Venezuela, Colombia, West Indies, New Caledonia, 
Madeira, and the Canary Islands. Unfortunately for our records of its 
distribution in this country another species has been very generally 
confused with it. It is abundant in the South, where it occurs both 
indoors and in the field. I have living specimens from the District of 
Columbia andjiave seen a series from Kentucky and Ohio. It prob- 
ably occurs with us still farther north. 
European writers, including Fauvel, have considered these two spe- 
cies as of oriental origin, and if this supposition be correct they were 
evidently introduced in South and Central America at a very early
