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 gTowing cotton stalks. It 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 larvee might have attacked the

 was noticed on neighboring hackberr}" trees. Injury In' this in,sect is 

 verv common to shade and fruit trees, especialh" to pear, in west- 

 central Texas. 



PAPAIPEMA NITELA Gucn. 



In Jul}', caterpillars presumably of this species (fig. 22) were tound 

 not uncommon, boring in the cotton stalks at Terrell, especially along 

 a small creek. The larvie enter the stalk 3 or 4 inches above the 

 ground, boring upward and causing it to wilt and die. The larvaj 

 were very common in the stalks of " bloodweed " (^m Jros^'^ trifidci) 

 in Brazos County, but none were found on cotton. June 24, 1904,
