collection came from Plolienkapf in Allgiiu. I took a 

 precisely similar specimen near Kellieim on June 3rd." 



It is very possible that the dark specimens noted 

 belonged to //r«?;(//.s, this is the only reference I have found 

 to the species having possibly been observed. 



S. (jraplwdactylus is said to feed on Gentiana lutca, the 

 food of grandis ; c&prodadyla on Gentiana verna. As an 

 abundant and Avider spread species, it is probable that the 

 latter feeds on vaiious gentians, verna, aeaulis, etc., li(fea 

 being more likely an exception than not. 



That X grandis should be attached to the supposed food 

 of >S'. gixq^lwdactyla, and at the same time more nearly 

 resemble roi^rodactyla, may equally point to the three forms 

 being distinct, or to all being races of one species.
