THE LESSER GRAIN-BORER. 35 
stuffed with rye straw. Of course this straw contaius some few loose grains 
of rye; however, I am at the present time cutting the heads off of the straw 
to try and eliminate any grain entering the collar. The grain has been pre- 
viously threshed from the straw. You will find live specimens in a box in the 
package. Trusting that through your office I may gain such information as 
will enable me to exterminate this bug or its egg before or after the collar is 
stuffed, and thanking you for any information that you may be able to furnish 
me, I remain, * * *. 
In addition to the notes and records which have just been fur- 
nished, the Bureau of Entomology has reports of the finding of this 
species in cereals and waste material in mills in different portions of 
Texas ; in flour at Denison, Tex. ; in rice at Crowley, La. ; in corn 
from Houston, Tex. ; in mill material generally throughout the State 
of Texas, and there is one record of the occurrence of the insect from 
Georgetown, Demerara, where it was imported in paddy rice from 
India. 
July 8, 1908, Mr. D. K. McMillan reported this insect very common 
in samples of grain from an old mill in Sherman, Tex., which was 
unused for 15 months. It was also very common in samples of rub- 
bish from a milling company in the same place. The adults bored 
holes through the cotton sacks, the cloth of which had a starch and 
whiting filler, thus liberating Camocorse, Calandra, and other grain 
insects in the sample bags. 
During February, 1910, Prof. R. H. Pettit, entomologist of the 
Michigan Agricultural Experiment Station, sent specimens found in 
wheat from a Detroit mill, and associated with other species. 
The bureau has also a note from Mr. Knight, of the Bureau of 
Plant Industry, United States Department of Agriculture, who 
brought seeds of white lotus in which this species was at work. 
BIOLOGIC NOTES. 
From a lot of insects obtained in 1881 observations were made by 
Mr. Th. Pergande, whose notes have been of assistance to the writer 
in the preparation of this chapter. 
From eggs deposited April 27 larvae were obtained on May 11, or 
in fourteen days after egg deposit. All the eggs were lying loose 
among the excrement of the insects at the bottom of the jar. 
The egg. — The egg is white, of elongate pear-shaped form, one end 
forming a rather narrow stem or neck, bearing on one side at its 
base a transverse impression or suture causing the egg to bend some- 
what to one side. Both ends of the egg are rounded ; the surface is 
slightly polished and apparently somewhat rough. The length of 
the egg is 0.6 mm., and across its thickest portion a little over 0.2 mm. 
The newly hatched larvw. — The newly hatched larvae were de- 
scribed as white, slightly yellowish toward the head ; head yellowish,
