mon name of Tridens is "The dark dagger/' and of Psi " The grey 

 dagger." If a row of each be placed side by side, and they be 

 looked at from a distance too great to notice the exact markings, 

 the darker hue of Tridens is easily seen, I also think it looks rather 

 browner. Newman, who professes not to know why Tridens is 

 called " The dark dagger," and to be unable to distinguish them, 

 gives a figure of each in which the difference is shown with great 

 clearness.

Megacephala

 Alni 

 Ligustri 



v. Coronula, Haw. I do not know this variety, unless it is the dark 

 form without the paler patch near the tip. 

 Kumicis 



v. Salicis, Curt. Darker and more uniformly coloured. 1 have one 

 with quite a brown shade. 

 Auricoma 



v. Pepli, Hb. Darker and more unicolourous. I do not know if 

 this is the v. MenyantMdis, of Haw. 

 Menyanthidis 



Staudinger gives a var. Salicis, Curt, of this species, as occuring 

 in this country. This appears to be in error for the var. of 

 Rumicis of the same name which he does not give. South gives 

 Salicis, Curt., as a synonym of rumicis, which it certainly is not, 

 and falls into the further mistake of copying Staudinger's error in 

 this species.
