Note on the genus Protenor StaL 



By E. Bergroth, Forssa, Finland. 



In his " Check List" Mr. Uhler has quoted the genus Tetrar- 

 rhinus Prov. as a synonym of Protenor Stal. In his faunistic work 

 on the Hemiptera of Canada, p. 335, Mr. Provancher protests 

 against this synonymy in saying: " M. Ashmead a confondu ce genre 

 avec le Protenor de Stal, mais ce dernier dit du Protenor: articulo 

 primo antennarum capitis apicem hand attingente." 



This is a falsification of Stal' s description. Stal says (Ofv. Vet. 

 Akad. forh. xxiv, 1867, p. 543): " antennis - - articulo primo capite 

 paullo breviore." There is, of course, quite another meaning in 

 these words than in the ones substituted by the learned abbot, and 

 there can be no doubt that Mr. Uhler was right in uniting Tetrar- 

 rhinus quebecensis Prov. with Protenor Belfragei Hagl.

" Among the Moths and Butterflies," is the title of a new book 

 for young folks, by JuHa P. Ballard, author of " Insect Lives." To 

 quote a newspaper book review: "it is so fascinating that every 

 child who reads it will at once begin to make a collection of cater- 

 pillars and cocoons." F- H. C.
