aneurus Walkley. Southern N. Mex. Host: Dendroctonus sp.?, D. adjunct us Bland.? Muesebeck 

 (1958) cited Dendroctonus sp. as a host without query, but none of the specimens in the 

 U. S. Natl. Museum collection are known to have been reared from Dendroctonus; notes 

 in the Hopkins file indicate that some of them emerged from trees infested with D. 

 adjunctus, and that all were associated with Dendroctonus. Because aneurus does not 

 seem to be too large to be a parasite of D. adjunctus, it seems possible that rearings 

 will confirm D. adjunctus as a host.
