NOTE ON THE HARRIS COLLECTION OF 



HETEROPTERA. 



By J. R. DE LA Torre Bueno. 



During a recent visit to Boston, through the courtesy of Prof. 

 C. W. Johnson I had the good fortune to examine the Harris 

 collection of Hemiptera. Many of the insects, as is well known, 

 passed through the hands of Thomas Say and were named by him 

 and in the absence of types of his species they may be so regarded. 

 The late Prof. P. R. Uhler also examined these insects at leisure 

 and based on his study his authoritative paper "Notices of the 

 Hemiptera Heteroptera in the Collection of the late T. W. Harris, 

 M.D.'i 



The custodian of the Boston Society of Natural History is to 

 be congratulated on the excellent condition of these precious relics. 

 Some one or two have suffered from Anthreni, but considering the 

 great age of the collection, the bulk of the specimens are in a 

 marvellous state of preservation. I shall not extend myself to 

 repeat all the details given in the paper by Uhler cited, but certain 

 notations on a few of the species will serve to clear up one or two 

 obscure points. 



Lygoeus turcicus Fabr., No. 54. The specimens from Michigan 

 under this label are the only ones correctly named. The others 

 are Lygoeus kalmii Stal, which is not mentioned by Uhler. 



Gonianotus marginepunctatiis Wolff, No. 65. The specimen 

 under this label and number is the common Eastern Emblethis 

 vicarius Horv. 



Naucoris poeyi No. 148, "Florida, Doubleday" is Pelocoris 

 carolinensis Bueno, characteristic. 



Ranatra fusca P. B. No. 151, Harris No. 65, determined by Say 

 according to Dr. Harris' manuscript catalogue, is undoubtedly 

 R. protensa Mont. It is certainly not nigra H. S., as a careful
