110 COLEOPTERA. 



dehilisy informs me that tlie S. opacus of Erichson is (as I 

 supposed) certainly identical with the insect to which he had 

 given the former name in MS. It appears not to have been 

 published, as Herr Dietrich detected the incorrect reference 

 of S. opacus as a synonym to S, carhonarius, alluded to by 

 me in the last '^Annual/' 



Mr. Crotch, in his Catalos^ue, follows Kraatz in sup- 

 pressing Erichson's species under niger, Mann.

 tuation, seems not unlikely to be referred also to the same 

 species.

 Mr. Sharp objects to De Marseul's use for this insect of 

 the name lapponicum, Zett., the earliest in date, and under . 

 which T noticed it in the last Entomologist's "Annual," as 

 Mannerheim had, prior to Zetterstedt, described another 

 Homaliuvi under tliat name. 



Choleva lon(^ula, Kelln. 

 :>Ir. Crotch (Eiitom. No. 32, p. 119) refers with certainty 

 the insect recorded by me as above to the piHcor7iis of Thom- 

 son ; doubting whether it be the i-eal C. longida of Kellner, 

 or whether Murray was right in supposing that species to be 

 merely elonjiate C. tristis. I consider that the insect I
