Nomenia 12-lineata, Packard. 

 Euchceca salienta, Pearsall. 



= 12-lineata, Auct. pars. 

 Euchceca comptaria, Walker. 



= perlineata, Packard. 



He argues in favor of this course in an article in this journal' headed 

 "Whom shall we follow?" and decides that so far as he himself is 

 concerned he will follow Dr. Hulst rather than Mr. Prout. 



Dr. Pearsall's contention seems to be, that as Hulst has so long been 

 our authority on North American Geometridee, his word must be taken 

 until it can be shown that Mr. Prout and myself are more likely to be 

 right. 



Of course one recognizes that this line of argument would be the 

 sound one in many, perhaps in most, cases, but in this particular instance 

 I believe Mr. Prout is right and Dr. Hulst wrong, and so, while admitting 

 the latter's great authority, I shall not follow him, ist, because the con- 

 clusions of Mr. Prout were arrived at after a very careful study and a more 

 prolonged study than Hulst could possibly have given this one insect, and 

 with a full knowledge of the different opinion Hulst had expressed j and 

 2nd, because in all the rest of the synonomy given by Hulst under the 

 species we are considering, the Doctor is entirely and manifestly wrong, 

 showing that he was not specially well informed as to this species or group 

 of species. 



I ask, will Dr. Pearsall follow Hulst and accept the other synonyms 

 placed \v\\\\. perlineata under comptaria, Walker? 



One of them is condensata, Walker, which should be placed under 

 Euchceca lucata, Guenee. The other is i/iclinataria, Walker, of which 

 the type (as a glance at the description will show, and as Hulst himself 

 once declared^) is a specimen of Xanthorrhoe ferrugata, a species with 

 fully pectinated antennje, and hardly to be confused with comptaria by 

 the veriest tyio. 



I argue then that if Dr. Hulst was wrong in two cases out of three, I 

 am justified in taking my friend's opinion rather than his in the third 

 instance.
