Resa 1861, Zool. Coleoptera) and also one by Quenselt, 
now in the Stockholm Museum. 
I do not refer to most of them, which are sufficiently 
well known and accurately determined in various collections 
I have seen. I was able to compare with all the types 
examined, examples either in the British Museum collection 
or in my own, with the solitary exception of Anchomenus 
li nbatus (limbaticollis Mun. Cat.), of which I have seen 
no other specimen. I may mention that Platymetopus 
melanarius proved, as I anticipated (1919, 150), to be 
identical with Gnathaphanus vulnervpennis Macl., and 
Harpalus subcostatus De}. Drimostoma rufipes (1919, 160) 
also proves to be identical with Coelostomus picipes Macl. 
Tchitcherin has already pointed out (Hor. Soc. Ent. Ross. 
xxxv, 1901, 166) that Stenolophus biplagiatus isan Acupalpus. 
There is one species which has been misidentified, viz. 
Anchomenus scintillans, and requires therefore some further 
notice. In describing his Anchomenus chalcomus (Trans. 
Ent. Soc. Lond. 1873, 280) Bates says, “ Very closely allied 
to the common Chinese A. scintillans (Bohem.), from which 
no difference is perceptible, except the abdomen being 
pitchy black (like the rest of the under-surface) instead of 
testaceous.” This seems a slender foundation on which 
to establish a new species, but I have before me Chinese 
examples labelled A. scintillans Boh. in Bates’ handwriting, 
and they certainly appear, apart from the rather lighter 
colour, identical with A. chalcomus. In the same volume 
of the Transactions (p. 330) Bates described his A. aeneo- 
tinctus, differentiating it from the species which he sup- 
posed to be A. scintillans. It is, in fact, identical with the 
true scintillans, so that Boheman’s name must displace 
Bates’, A. scintillans Bates in litt. (not Boh.) becoming a 
synonym of his A. chalcomus.
