THE COLLECTION OF HEMIPTERA, 
E. H. Gibson, Custodian of Hemiptera at the National Museum, proposes to 
carry on what might be termed a "clearing house" for additions, corrections, 
mendations, etc., of Van Duzee's recently published catalogue of the Hemiptera 
of North America and he suggests that entomologists noting omissions or errors in 
the catalogue communicate with him. From time to time tabulations of such correct- 
ions will be made and sent out in the form of a circular letter to any one inter- 
psted in the subject. (E. H. Gibson.)
