Athous haemorrhoidalis

Duff seems to have an inconsistency in his Athous key. In couplet 3 he states that on haemorrhoidalis antennomere 3 is clearly longer than antennomere 2, but antennomere 3 is only slightly longer than antennomere 2 on vittatus, which is fine, but at the previous couplete he requires antennomere 3 is only slightly longer than antennomere 2 for both haemorrhoidalis and vittatus. I suppose "slightly" is a relative term and compared to bicolor, the alternative at couplet 2 with antennomere 3 about twice as long as antennomere 2, slightly longer is the best option to take here, but really, it's more than slightly longer in haemorrhoidalis.
