can have anything whatever to do with the Mycetopha- 
gideous genus Symbiotes,—Dr. Heer being far too acute 
a Coleopterist ever to have permitted a totally dissimilar 
form like the latter to be introduced amongst his ordinary 
Nitidule, in the situation moreover which the following 
specific sequence will show :—N. flexuosa, F., 10-guttata, 
F., rubiginosa, Heer, silacea, Hbst., obsoleta, F. More- 
over, apart from the description itself, the very size 
given for the N. rubiginosa (namely a line and a quarter) 
renders it quite inapplicable to the Symbiotes pygmaeus— 
which measures from seven-eighths to (at utmost) one 
line. Until therefore further evidence is adduced, I shall 
refuse to believe that Heer’s insect and Hampe’s are even 
congeneric,—so much more, therefore, conspecific.

(Sp. 485) Saprinus ignobilis. 
In the Appendix to the ‘ Coleoptera Hesperidum’ I 
called attention to the fact that De Marseul, without 
stating the reason why, has changed (7 Abeille, 1. 853; 
1864) the title of my Saprinus ignobilis into “ S. Wollas- 
toni.” I think it sufficient just to mention this; though 
until some explanation on his part be forthcoming | 
cannot believe that the alteration is valid, not knowing 
on what principle it has been made. 
(Sp. 489) Saprinus nitidulus. 
The name “ semistriatus”’ for this common and widely- 
spread Saprinus (which has been cited, also, by Mr. 
Crotch from the Azores) seems to have the precedence 
over “nitidulus.” Hence its synonymy must be thus 
corrected :— 
Saprinus semistriatus. 
Hister semistriatus, Hbst., Kif. iv. 306 (1791). Hister 
nitidulus, Fab., Syst. Hleu. i. 85 (1801). Saprinus niti- 
dulus, Woll., Ins. Mad. 215 (1854) ; Id., Cat. Mad. Col.
