OBTHOSOMA BRUNNEUM Forst. 
A larva, probably of this species, was sent to the Bureau of Ento- 
mology by Prof. Wilmon Newell, from Villa Rica, Ga., where it was 
stated to be boring into the bases of growing cotton stalk-, [t is 
probable that this injury is more or less accidental. The larva usually 
works in dead wood; and possibly where dead wood occurred in the 
cotton field and was plowed up, the larvae might have attacked the 
cotton.

In October, 1904, numerous specimens of cotton stalks cut off about 
1 foot above the ground were received from Waco. Tex., the work 
being undoubtedly that of this species. Subsequently the fields were

visited, but none of the beetles could be found, though similar work 
was noticed on neighboring hackberry trees. Injury by this insect is 
very common to shade and fruit trees, especially to pear, in west- 
central Texas. 
PAPAIPEMA NITELA (uien. 
In July, caterpillars presumably of this species (fig. 22) were tound 
not uncommon, boring in the cotton stalks at Terrell, especially along 
a small creek. The larva 4 enter the stalk 3 or 4 inches above the 
ground, boring upward and causing it to wilt and die. The larvae 
were very common in the stalks of ' 'blood weed " (Ambrosia trijida) 
in Bra/os County, but none were found on cotton. June 24, 1904:,
