and its general appearance will serve readily to distinguish it from 
the tobacco beetle. Several species of insects which occasionally are 
found living or feeding in dried tobacco are likely to be mistaken for 
the tobacco beetle. These are enumerated below. 
A reddish-brown beetle (Thaneroclerus 
girodi Chevrolat), considerably larger than 
the tobacco beetle, often may be found in 
tobacco or in boxes of cigars. This species 
feeds on the different stages of the tobacco 
beetle. The adult, larva, and pupa stages 
are shown in Plate I, figure 3; Plate ITI, 
figure 5; and Plate IV. This insect is more 
fully discussed in the section dealing with 
the parasitic and predacious enemies of the 
tobacco beetle. 
The larger tobacco beetle (Catorama 
tabaci Guérin) (PI. IT, fig. 1; Pl. ITT, figs. 
2, 4: text figs. 9 and 10) attacks cured to-

and its larger size makes it still more 
destructive than is the common species. Cigar tobacco injured by 
Catorama tabaci is shown in figure 6. So far as known this species 
has been reported only from three localities in the United States. 
Tt was found in tobacco in this country for the first time in 1912. 
One of the leading cigar companies at Key West, Fla., reported the 
insect to the Bureau of Entomology and sent specimens collected in 
a shipment of cigar tobacco from 
Habana, Cuba. At about the same 
time a similar report accompanied 
by specimens was received from a 
cigar company located in Philadel- 
phia, the beetles having been found 
also in a shipment of Habana to- 
bacco. In the following year speci- Fic. 9—The larger tobacco beetle

of Entomology in bales of Habana tobacco which were being re- 
moved from a bonded warehouse at Key West. Fla., and also by 
the writer, in a bonded warehouse in Tampa, Fla. The records ob- 
tained indicate that the insect is native to Cuba. It was introduced 
into Paris, France, from Cuba and was first described by Guérin- 
Ménéville (11) from the Paris importations in 1850, having been — 
found in Habana cigars.
