THE CANADIAN ENTOMOLOGIST. Ill 



The annoyance caused by the numerous, and at times rather obtrusive, 

 misprints, which have come to be somewhat characteristic of its medium 

 of publication, is offset to some extent by the more satisfactory typographic 

 form, the new dress being more becoming than the old. I notice that Mr. 

 Fall makes use of a word iimbone, to express a protuberance of the surface; 

 this word also occurs frequently in the writings of Dr. Horn and others. 

 On consulting the dictionaries, I find that the word umbo, which has been 

 adopted by the English language directly from the Latin, has, for a French 

 equivalent, timbon and Italian umbone ; but it is not quite apparent why 

 we should use the Italian word in preference to the Anglo Latin 2imbo, 

 which is shorter, more rational and less liable to be mistaken for an 

 Eiiglisii singular of the Latin plural nmbones, if perchance construed as 

 forming two syllables instead of three. 



It is also impossible to confirm the correctness of the geographic 

 name " Baboquivaria " used by Mr. Fall and others. The atlases give 

 either Baboquivari or Babuijuivari, the latter form in .Sieiler's Handatias. 

 The form " Baboquivaria " is cmly (juotable from the pin-labels of our 

 genial and old-time friend Prof Snow, and was presumably so printed 

 under misapprehension. 



It would seem to be almost time that the true value of the syiionymical 

 list of my early species published by Dr. Horn, and embodied in the 

 Henshaw List, should have become known to systematists. I drew 

 attention to the unreliability of this list in one of my papers published in 

 the Bulletin of the California Academy, and it would be scarcely worth 

 while to allude to it again, were it not necessary to remark that in blindly 

 following the synonymy indicated by Dr. Horn, the author of the work on 

 Diplotaxis has fallen into an error, which he migiit have avoided had he 

 read my description of D. icvicula, and not taken it for granted that it was, 

 as stated by Dr. Horn, identical with the punctata, of LeConte, inhabiting 

 a different region : for Mr. Fall does not admit that punctata occurs in 

 Arizona, and yet places levicula, from Arizona, as a synonym of that 

 Texan species. On comparing my type with LeConte's material many 

 years ago, I made up my mind that it was closely related to carbonata. 

 A perusal of Mr. Fall's paper indicates that he has redescribed it under 

 the name riifiola. This name is therefore in all probability a synonym of 

 levicula. 



In Mr. Fall's Revision of the Ptinidse (Tr. Am. Ent. Soc , XXXI, p. 

 274), the author has apparently strained pretty hard to make a synonym
