This speeies has been the source of no little confusion .as may be told from 

 the long list of synonyms above. I am especially indebted to .Mr. .1. T. Monell 

 and Mr. John J. Davis for their aid in dcti-rmiiiinjj it. Mr. Davis writes: "Have 

 just looked at the slides which you sent and consider them as Siphorortfne raprrar. 

 in other words what I called Siphorori/ne {lli/adaphis) pastinaeae I.inn. I consider 

 lli/adaphis the correct name of this genus. Even the European students seem to 

 be unable to say whether capreae and pastinaeae .are synonymous or distinct and so 

 I simply follow Schouteden and used the name pastinaeae. S. talicis Monl. and 

 .S'. arehangelicae Oest. are synonyms of capreae. I intended to say above that the 

 tubercle on the penultimate abdominal si-gmeiit seems to be a good s|)ecific char- 

 acter of this species. F know of no other Ili/adaphls bearing this IuIktcIc." May
