28 THE CANADIAN ENTOMOLOGIST. 



is hence almost impossible ; his type also cannot be found. In my 

 opinion he may have had a form of Walkeri before him ; but whether 

 this, or vinule?ita, or even tri-stigmata, or Morriso?ii, cannot, with 

 certainty, be made out from his comparative description. As I have 

 separated all the American forms under distinct names, and Mr. Thaxter 

 has shown the distinctness of most of them by breeding, these names 

 should be retained until further evidence be forthcoming as to the single 

 species indicated by Guenee. A different course would be the result of 

 mere opinion and, without scientific value, only make confusion. 



Tribe Calocampini. 



The vestiture resembles that of the preceding tribe, but the wings are 

 narrower, the legs proportionately shorter, unarmed. The palpi are short; 

 male antennse thickly ciliate. The primaries are blunt, not widening out- 

 wardly as much as usual, with gray or brown, streaky, stone-like mark- 

 ings, hence the name LithophaJie^ used for the principal genus by Hiibner. 

 This genus is incorrectly called Xylina ; Hiibner's genus of this name 

 having for type a species of Hade/ia. It seems to have been customary 

 for earlier authors to take names out of Hiibner's writings and apply them 

 arbitrarily, with or without diagnosis. The injustice and absurdity of 

 this proceeding must be evident to all thinking persons. Only an empiric, 

 full of his own importance and wishing to elevate himself by contrast, can 

 commit the blunder. If Hiibner has not given neurational characters, it 

 is because neurational characters were not then known ; at least he has 

 not given us incorrect descriptions of the venation, which is in his favor 

 as compared with certain quite modern writers. Lithophane has eight 

 European and about twenty-five American species ; again a large pre- 

 ponderance. Of these, Thaxter I represents the European /^rw^^-r/a / but 

 no variety of the latter corresponds with our American form, which must be 

 regarded as a distinct representative species accordingly. The European 

 ingrica seems to be represented also by pexata and its variety IVashing- 

 tojiiana, although in the latter instaiice nearer comparisons are necessary, 

 which I have not been able to make, Lithomia Hiibn., which differs by 

 the character of the palpal vestiture and the elevated collar, has appar- 

 ently a representative species \n germana ; but I strongly suspect that 

 this is really identical with the European solidaginis. Calocampa has
