52 ENTOMOLOGICAL SOCIETY 



MAY IST, 1890. 



Nine members present. President Marx in the chair. 



The committee having in charge the preparation of a list of 

 the insects occurring within the District of Columbia made a 

 partial report. 



It was moved by Mr. Howard that the name of Mr. Town- 

 send be added to the sub-committee on Diptera, and that of 

 Mr. Marlatt to the sub-committee on Hymenoptera. 



The prosecution of the work was urged by Prof. Riley, and 

 in the general discussion it was shown that considerable work 

 had already been done. 



Mr. Townsend then read the following paper : 



HEMIPTERA COLLECTED IN SOUTHERN MICHIGAN. 



BY C. H. TYLER TOWNSEND. 



During my collecting in Michigan I made a small collection 

 of Heteroptera and Homoptera, which is now in the National 

 Museum. Bighty-five or ninety species of Heteroptera were 

 collected in the neighborhood of Constantine, which this list 

 is intended to record. About half of these were very kindly 

 named for me by Mr. Uhler some years ago. The remainder, 

 collected since then, have been worked over with the aid of 

 Prof. Riley 's identified material in this group. The localities 

 in parentheses are those given in the Uhler list.
