Campoplex niger Gahan and Rohwer (not Provancher), Can. Ent., vol. 40, p. 

 335, 1917. 



Provancher himself synonymized his Paniscus quebecensis with 

 suaveolens, and A. B. Gahan's note (in MS.) says "not in Public 

 Museum, Quebec, unless under Exetastes suaveolens Walsh. All 

 specimens under this name are the same species." 



The name Exetastes provancheri Dalla Torre was proposed and , 

 comes into the synon3miy of suaveolens because of the obvious mis- 

 labeling of a specimen in the Provancher collection. In his study of 

 the Provancher tj'pes Davis found a specimen labeled "Campoplex 

 niger Prov." and in his report doubtfully referred this specimen to 

 Exetastes. Dalla Torre, finding the name niger preoccupied in 

 Exetastes, proposed the name provancheri and placed Campoplex 

 niger Provancher in the synonymy. Wiien A. B. Gahan was studying 

 the Provancher types he evidently found the same specimen that 

 Davis had seen, for he compared with it a specimen of suaveolens and 

 pronounced them identical; and Gahan and Kohwer designated the 

 Provancher specimen as lectotype of Campoplex niger Provancher, 

 That this specimen can not be the type of Campoplex niger is at once
