SPECIES NOT INCLUDED. 
Athysanus acuminatus Bak. 
This species is only known by the single, faded, male type and 
while it without doubt belongs to the Subgenus Conosanus its 
character could not be made out with sufficient certainty to war- 
rant including in the synopsis. 
Athysanus ornatus Gill. 
This species belongs to the genus Driotura O. and B. of which 
A. gam7nar0id.es is the type. 
Athysa?ius artemisiae G. and B. 
Both the specific value and generic position of this species are 
still in doubt. It does not belong to any of the groups enumer- 
ated above and probably should not be included in the genus at all. 
Athysanus litigiosus Ball 
This species was only doubtfully referred here in the original 
description and does not fall readily into any of the above groups. 
When more material can be studied it will probably be possible 
to refer it to another genus.
