* Cathartus advena Waltl.—Also taken at the Exposition. A widely distributed 
general feeder like S. surinamensis, but not so common or injurious. 
Pharaxonotha kirschi Reit.—This species was originally described from Mexico, and 
was found in the Mexican and Guatemalan exhibits of the Exposition, infesting corn 
meal and edible tubers. Sufficient material wassecured for rearing and other experi- 
ment, and my experience with this insect indicates its a bility to hold its own with the 
other tropical species that have already been introduced here. Its occurrence has 
been noted in Brazil, where it may be native, as well as in tropical Central America. 
Until December of 1895, when Mr. E. A. Schwarz captured a single individual of this 
insect in the vicinity of San Antonio, Tex., it had never been taken in this country. 
It was found under dried leaves remote from human habitation. Although this 
shows that the species occurs within our faunal limits, it was probably imported 
across the Mexican border, and there is still danger of its introduction into store- 
houses through commerce with Mexico, and especially since it is not confined for 
food either to meal or tubers. 
Litargus sp.—A mycetophagid closely allied to our native L. balteatus Lec., breed- 
ing in abundance in potatoes, yams, and other edible tubers at the World’s Fair. 
None of the species of this genus are known to be injurious, and it is probably only 
a scavenger. 
* Tenebroides mauritanicus Linn. (cadelle).—A common species of omnivorous hab- 
its, but chiefly injurious to cereals; probably indigenous to tropical America, but 
long ago diffused by commerce over nearly the entire globe. 
*Carpophilus hemipterus Linn.—An enemy of stored fruits. Recorded by Dr. Sharp 
from Cordova and Jalapa. 
Carpophilus pallipennis Say (corn sap-beetle).—Colleeted by Dr. Edw. Palmer and 
the late H. K. Morrison in Mexico. Sometimes injurious to stored corn in our South- 
ern States. 
*Carpophilus dimidiatus Fab.—Taken in numbers in corn meal at the Columbian 
Exposition by the writer. Widely distributed in Mexico. Lives in cotton bolls and 
in ripening or overripe fruit in the South. 
*Dermestes vulpinus Fab. (leather beetle).—Living on hides and dried fish in the 
Mexican exhibit at the Exposition. Also in the National Museum from another 
source in Mexico. 
Dermestes carnivorus Fab. (mucoreus Lec.).—Of similar habits to the preceding, and 
said to injure bacon and hams after the manner of that species. Recorded from 
Mexico and from Texas. Nearly cosmopolitan. 
*Necrobia ruficollis Fab. (red-necked ham beetle).—Recorded from Guanajuato by 
Gorham. Taken on dried fish at the Exposition. 
* Necrobia rufipes Fab. (red-legged ham beetle).—Recorded from several localities 
in Mexico by Gorham. Taken with the above. Also infesting cheese. 
Dinoderus truncatus Horn.—This species was first recorded by the writer from 
Mexico (Insect Life, vol. vu, p. 327) from specimens found infesting corn and edible 
tubers at the Columbian Exposition. It was found in corn in the Mexican exhibit 
at the New Orleans Exposition; also in samples of Mexican seed corn in the Botan- 
ical Division of this Department. This is an aggressive species and will bear close 
watching. It is able to subsist on almost any sort of roots and tubers, and would 
create great havoc should it become introduced into our granaries, as the adult has 
a habit of leaving the grain in which it has bred and boring into woodwork or any- 
thing else that obstructs its path. I have known it to bore into both pine and hard 
black walnut. Described from California from mutilated material, probably of acci- 
dental occurrence as the species has not been recorded from there since. 
Dinoderus pusillus Fab.—Recorded from Mexico by Rev. H.S. Gorham, who states 
that it is ‘common in wood of sugar casks.” It also injures grain. At the Colum- 
bian Exposition it occurred in two exhibits from Mexico. 
* Sitodrepa panicea Linn. (drug-store beetle).—A well-known cosmopolitan species, 
injurious to cereals and other seeds, drugs, tobacco and other dried plants, and a 
great variety of dried substances. Recorded from Cordova and Pueblo by Gorham.
