Bellevoyei, de Saulcy. 



sinuatocollis, Ktz., nee Boisd. et Lac. 

 Dr. Kraatz (Berl. Ent. Zeit., xii, 1868, 349) gives the 

 above as the correct synonymy of De Saulcy's species, for 

 a description of which see p. 208 of vol. iv, Ent. Mo. Mag. 

 He states that the sinuatocollis of his Ins. Deutschl. is not 

 the true species of that name, but is identical with M. Belle- 

 voyei, over which Miller's affinis, which is also identical 

 with it, has priority. It may be remembered that in Berl. 

 Ent. Zeit., 1862, Dr. Kraatz stated 31. Bellevoyei to be 

 identical with sinuatocollis, an evidently erroneous opinion 

 which is now intellif]^ihly accounted for, and which also 

 accounts for my inability (loc. cit.) to satisfactorily follow 

 Kraatz in his characters for the latter species. But, admit- 

 ting Dr. Kraatz to be now correct in his appreciation of 

 Bellevoyei, I cannot quite see how his old si?iuatocollis can 

 be identical with that species, as he gives male characters 

 that accord with sinuatocollis and do not apply to Bellevoyei, 

 with which insect other parts of his description are at 

 variance. 



31. Catops flavicornis, Thomson, Skand. Col., ix, p. 346; 



G. R. Crotch, 1. c, p. 69. 



Mr. Crotch, remarking that he cannot clearly make this 

 out, says that most of his C. nigricans appear to agree with 

 Thomson's recently described species. 



Thomson (who gives no definite size) states it to be inter- 

 mediate between ^^icipes and nigricans, from the former of 

 which he distinguishes it by the more pronounced club of
