The other exhibits visited in which, injurious iuseets "were found, and from which 
more or less infested material was removed, were as follows : Those of Algeria, 
Biazil, Cape of Good Hope. Ceylon. Japan, Liberia. Orange Free State. Paraguay. 
Siam. Spain and the Spanish Colonies, and Uruguay, in the Agricultural Building; 
Costa Rica, the French Colonies of New Caledonia and Indo-China, Tunis. Turkey, 
and Venezuela, in the government buildings of their respective countries. 
The foregoing list includes all the exhibits which contained insects of economic 
importance. The cereal exhibits of other countries were also visited, but inspection 
showed that they were either free from infestation or contained only a few of the 
more common insect pests, rendering no action necessary. 
The exhibits in which no insects of a dangerous character were found were as 
follows: Those of Java. Curacao. Italy, British Guiana. Johore. Trinidad. Ecuador. 
Canada and the other British provinces of North America. Russia, and the other 
North European countries in the Agricultural Building; those of Greece and 
Jamaica in the Horticultural and Manufactures Buildings, respectively: and the 
exhibits of Colombia. Haiti. India, and Ceylon in their respective government 
buildings. 
INSECTS AFFECTING ANIAIAL PBODUCTS. 
It was not deemed necessary to make an extensive study of the insects- 
affecting woolens, furs, hides, and other animal products on exhibit, as- 
there is comparatively little danger of introductions from abroad. A 
few species, however, were observed and collected by Mr. Chittenden, 
all (with possibly one exception) cosmopolitan and widely diffused 
throughout this and other countries. The following is the list : 
Larder Beetle (Dermestes lardarius L.). — About Exposition grounds. 
Leather Beetle {Dermesies vulpinus F.). — Living on dried fish and hides, in Mexican 
exhibit. 
Bed-necked Ham Beetle (Necrobia ruficolHs Fab.). — With the above on dried fish. 
Bed-legged Ham Beetle (Xecrobia ruiipe* DeG. ). — With the two preceding, on fish 
and on cheese. 
Cheese Skipper (PiopkUus casei L.). — Accompanying the preceding, on cheese. It 
also attacks hams and has received special mention in an article in the last number 
of Insect Life (pp. 170-175) and in the Extracts from Correspondence in the pres- 
ent number. 
Irogoderraa tarsal* Melsh. — Breeding by thousands in silkworm cocoons in U. S. 
Government Building. A well-known museum pest, probably identical with a 
European species. 
INSECTS NOTICED IN THE POKESTBV BUILDING. 
Time did not permit of very extensive collecting in the Forestry 
Building. From time to time, however, as opportunity offered, Mr. 
Chittenden visited this building, and a few species, all Coleoptera. 
were taken, a list of which is furnished herewith. All but two species 
were picked up from the windows where they were resting, and it is 
therefore impossible to state the locality from which they were brought. 
This is particularly true of the first four species, which, with the excep- 
tion of the La-mophlceus. are all cosmopolitan and might have been 
brought into the building with foreign exhibits, in packing material or 
otherwise, or have flown in at the open doors or windows. Several 
other species besides those mentioned in the list were observed in this
