A Parasite of tho Cottonwood Boror B ae t ia (CoL, Dip.). 



While rtodying the effects of poison l«its 00 grasshoppers inagrove 

 of Cottonwood trees hi western Kansas, fa the snmmer of 191J. the 

 writer was impressed by the large mimber of dead Cottonwood borer 

 beetles (PUclodtrm sc^lalor Fabw). Dead beetles were found at the 

 ba»cs of the trees and on the gionnd at d i stanrrs varying from one 

 to three fret away. 



The conclusion was drawn at once that they had been poisoned by 

 the bran mash spread over the ground for the grasshoppers. 



It was to test the vmlidity of this coocfa s ion that a large number 

 of the Uvii« and dead were brought to the laboratory and a Gotieit 

 test for arsenic applied. This gave negative rcsohs boi J" nrrmrJnK 

 them we found them to be parasitized. 



AD the rcmaininR Iwctlc* were placed in b ree dmg cages ami over 

 go per cent. «>f the l>eetle« were found to be parasitixed by a fly iden- 

 tified hy Mr. W. R. \Valt.»n as Sarcofkaga vfricauda Coq.. heretofore 

 reared only from grasshoppers. P. s<alator Fab. is thus given ss a 

 new host for this dipterous pnrastte.— H. B. HuiranfoaD, The Univer-
