resemblance' to the two preceding species, was received at this office in December, 
1895, from the Atlanta Exposition, where it was found in Indian corn and ehiek>peas 
(Cicer arietinum) in the Mexican exhibit. So far as we know, this Is the first instance 
of its occurrence in either stored grain or legumes, although there is one record, by 
Mr. Townsend, of its having been found in dried ginger in Jamaica (Institute of 
Jamaica, Notes from the Museum, No. 78). Occurs in Florida and South Carolina, 
but does not seem to be known with us as a storehouse pest. 
Arwoerus l faScieulatua DeG. (coffee-bean weevil). — A series of this anthribid beetle 
was collected by Dr. Palmer at Acapulco. It is disposed to omnivorousness, being 
known to breed in raw coffee berries, cacao beans, mace, nutmegs, cotton bolls, the 
seed pods of the coffee weed (Cassia sp. ), and a plant called wild indigo, probably a 
species of Indigo/ 'era. This insect is already well known throughout the cotton States, 
ami beetles are sometimes found in the Northern States in articles of commerce. 
Cryphalus jalappce Letz. — This little scolytid borer is probably indigenous to 
Mexico, but is often imported into other countries with commercial jalap, upon which 
it lives. Its presence is not considered detrimental to the drug. 
* Sitotroga (Gelechia) cerealclla 01. (Angoumois grain moth). — This species is a 
powerful rival of the two Calandras as a granary pest. Like them, it thrives on 
cereals of all kinds and is nearly as well distributed. At the Columbian and Atlanta 
ExpositionSj and collected by Mr. Townsend and others. 
I'.pliestia lcnehniella (Mediterranean Hour moth). — This scourge; of the Hour mill was 
breeding in a large exhibition case from Mexico at the Exposition, but the colony 
was promptly destroyed and the introduction of the species at Chicago thereby pre- 
vented. It has obtained a looting in several portions of the United States, being 
particularly destructive on the Pacific Coast, bnt in the East and the South it is still 
very limited in its distribution, and its introduction through Mexico into Texas and 
other Southern States is more to lie dreaded than that of any other storehouse insect. 
Plodia interpunctella Hbn. (Indian-meal moth). — A wide-spread species, of omniv- 
orous habit. In grain and dried fruits from Mexico both in the agricultural and 
horticultural buildings at the World's Fair. It was reared from cacao beans from 
Mexico, and from edible acorns collected in Chihuahua by Mr. Townsend. 
Tinea biscUidla Hum. (Clothes moth). — A series of this moth has been received from 
Dr. E. Duges, Guanajuato, Mexico, with, the statement that the insect does much 
damage to stored corn. The species has in this instance, perhaps, been confounded 
with Sitotroga oerealella, although I have myself reared it from stored wheat infested 
with the latter insect. 
Carphoxera ptcharia Riley (herbarium geometer). — This pernicious herbarium 
pot was described from material fust found infesting dried plants received at this 
Department from Mexico and Lower California, and it is more than probable that 
these insects were introduced from that country. 
Piophila casei Linn, (cheese skipper). — At the Columbian Exposition in cheese; 
also injures ham. 
Atropos sp. — In the Mexican exhibit at the World's Eair. 
Gama8U8 spp. — Two undetermined mites of this genus, with the preceding in corn. 
In addition to the above, a few other species not positively known to occur niMex- 
ico should receive at least passing mention here, as there can be little doubt, from 
what is known of their distribution, that they occur in that country. These are: 
Cathartus gemellatus, the "red grain beetle" of our Southern States; Ephestia elu- 
tclla, or chocolate moth; Anthrenus verbasci (varius), a common museum pest; Tro- 
goderma sternale Jayne, a species of somewhat similar habits to the preceding one; 
Calandra linearis, the tamarind-seed weevil ; Alphitophagus bifasciatus, a cosmopolitan 
species often found in storehouses. 
1 Arafcerus is the original spelling of this genus (Schoenherr's Cure. Disp. Meth., 
p. 40; Gen. et Sp. Cure, vol. I, p. 173), hence must take precedence over Arawerus. 
-During April, while this bulletin was going through the press, the discovery of 
the Hour moth was announced in a mill near Saltillo, Mexico.
