* Lasioderma serricorne Fab. (testaceum Dufts.) (cigarette beetle). — Mentioned by 
Gorhaui from Vera Cruz. Of very similar habits to the above, but not so common, 
and chiefly injurious to tobacco and drugs. 
* Tribolium ferrugineum Fab. (rust-red flour beetle). — An important enemy of stored 
cereal and other products, of wide distribution. Iu the Mexican exhibit at the 
World's Fair ; also recorded from there. 
* Tribolium con f mum Duv. (confused flour beetle). — Mentioned by Dr. Champion as 
occurring in Mexico, and collected by Mr. Townsend. Of similar habits to the pre- 
ceding. 
* Echocerus maxillosus Fab. (slender-horned flour beetle). — This species is probably 
native to South America and perhaps also to Mexico. Common in our Southern 
States under bark and in cornfields as well as in the granary. 
* Echocerus (Gnathocerus) cornutus Fab. (broad-horned flour beetle). — Champion 
states that this sj)eeies has been introduced in Mexico. I am, however, inclined to 
consider it as not generically distinct from Echocerus, and hence, with other species 
of the genus, as indigenous to the New World. Although cosmopolitan, it is still of 
limited distribution in the United States, being comparatively unknown outside 
of California and in the neighborhood of the Atlantic seaboard. 
Sitopltagus hololeptoides Lap. — This species is related to the preceding and is known 
to have been found in flour. It is undoubtedly indigenous in Mexico, but is unknown 
in the United States. As it is probable that it occurs like other allied forms chiefly 
under bark, its introduction with us would not positively prove disastrous. 
Palorus subdeprcssus Woll. — The flour beetle mentioned by Champion under the 
name of Palorus melinus Ilbst. (Biol. Centr. Arner., Col. vol. iv, pt. 1, p. 174) as having 
been collected by Dr. Edw. Palmer, of this Department, at Minas Viejas, has since 
been determined by the same writer as the above-mentioned species. It occurs in 
granaries in Europe aud elsewhere, also under bark. In our Southern States it has 
been found, but only under bark. 
* Tenebrio obscurus Fab. — Reared from a larva collected in Mexico by Dr. Palmer. 
The larva.', of this species and T. molitor are the familiar " meal-worms" and have 
probably both been introduced into Mexico as food for song birds. 
* Alphitobius diaperinus Panz. 1 — Mentioned as occurring in Mexico by Champion. 
Habits similar to the meal-worms, with whjch it often occurs. Widely distributed. 
* Aljihilobius piceus 01. — Also recorded by Champion, who states that he found it (at 
Panama) " amongst old bones thrown out from the slaughterhouses.*' Cosmopol- 
itan, but practically limited to the South in the United States. 
* Jiruchus obtectus Say (common bean weevil). — In the greatest abundance in the 
Mexican exhibit at the Exposition, and sent also by Mr. Townsend. A well-known 
enemy to beans almost everywhere. 
* Iiruchus 4-maculatus Fab. (four-spotted bean weevil). — A common species in our 
Southern States and said by Sharp to occur in Mexico. 
* Iiruchus (chinensis Linn.) scutellaris Fab. (cowpea weevil). — Also recorded by 
Sharp from Mexico. 
Spermophagus pectoralis Slip. — This species, as I have already pointed out (Insect 
Life, vol. vn, p. 328), breeds like our common Jiruchus obtectus in stored beans, and 
as it is congeneric with other species belonging to our United States fauna its intro- 
duction into this country in beans should be avoided. It was originally described 
from Central America and was breeding at the Exposition in beans from Brazil, as 
well as from Mexico and Guatemala. 
* Calandra granaria Linn, (granary weevil). — In grain and chick-peas collected 
by the writer at the Exposition and by Mr. Townsend in Mexico. 
Calandra oryza Linn, (rice weevil). — This species attacks all sorts of cereals and 
is as well distributed and injurious probably as any known insect. It was p resent 
iu injurious numbers in nearly every grain exhibit at the Columbian Exposition, and 
has been sent us by Mr. Townsend and others from different parts of Mexico. 
Caulo2)hilus latinasus Say. — This little cossonine weevil, which bears some slight
