36 BULLETIN 737, U. S. DEPARTMENT OF AGRICULTURE. 
Aplestomorpha vandinei Tucker was found abundant in a tobacco 
warehouse at Clarksville, Tenn. Specimens of this parasite were 
collected by Mr. J. U. Gilmore, of the Bureau of Entomology, and 
placed with larvee of the tobacco beetle, from which specimens of the 
parasite were reared later. The egg and also the larval period was 
found to be six days, and the pupal period about 7 days. The larve 
were observed to feed externally on both larva and pupa stages of the 
tobacco beetle. Specimens were determined by Mr. A. A. Girault, of 
the Bureau of Entomology. Fullaway (79) records an undetermined 
species of Pteromalus reared from the tobacco beetle in Hawaii. 
Jones (77), in the Philippines, describes and figures Vorbanus sp., 
which attacks larve and pupz of the tobacco beetle while in the pupal 
cells. 
Catolaccus anthonomi Ashmead has been recorded as a parasite of 
Lasioderma serricorne (43), but Mr. J. C. Crawford considers this 
an error. The original specimen can not be found. 
OTHER ENEMIES. 
Various species of mites are found frequently in tobacco, and some 
of these have been found to feed on eggs of the tobacco beetle. At

the solpugid in order to reach larve or pupx of the tobacco beetle (Lasioderma 
serricorne) within the cigar. 
Tampa, Fla., considerable difficulty was experienced in keeping eggs 
used in experimental work from being destroyed by the mites. 
Specimens of these were examined by Mr. Nathan Banks, then of 
the Bureau of Entomology, and found to be a species of Cheyletus. 
The larva form of a mite belonging to this genus was observed to 
insert its beak into the eggs of the tobacco beetle, remaining in this 
position for some time, and leaving the eggs more or less collapsed. 
The adult females of this species were observed to stand guard over 
their own eggs, which were deposited in clusters and kept under-~* 
neath the female. The clusters contained from 20 to 30 eggs. A 
mite belonging to the family Eupodidae, genus Rhagidia, has been
