208 Osten Sacken: Synonymica etc. No. IL 



Trypeta pulla Wied. A. Z. II, 506 (sine patria) is thc same as 

 Amphicnephes pertusus Loew, Monogr. etc. III, 84, Tab. 8, f. 1 

 (United States). The type being in the Museum in Vienna, it will be 

 easy to verify this synonymy. At the same timc it is in the interest 

 of tlie stablility of nomenclature, that spccies sine patriä should not 

 be allowed to lay claim to priority. The identification of such species, 

 withoufc spcaking of the useless labor it entails, involves an dement 

 of uncertainty, which will in most cascs prevent a careful writer from 

 taking any notice of them. 



The threc above-quoted synonymies are derived from thc cumparison 

 of the descriptions only, not of type-specimens.
