types of the latter: these are now referred to Adela Ltr., and Nemophora Hb.—it will 
be convenient to cite degeerella L. as the type of * Alucita F. (nec L.). 
Latreille having established the synonymy Ypsolophus F. = Cerostoma Ltr. (Type: 
vittella L.), it is satisfactory to learn from Mr. Busck, who examined the Fabrician 
types in the Royal Museum at Copenhagen in 1908, that “there are found in their 
original order only six species under the genus Ypsolophus and all of these belong to 
Cerostoma” [Pr. Ent. Soc. Wash. 11 89-90 (1909)]. Latreille has been followed by 
Hiibner, Guenée, Doubleday, etc., in his use of Ypsolophus (Ypsolopha), while Zeller 
(1839) seems responsible for the erroneous use of Ypsolophus in the Gelechiadae. 
Stainton adopted Zeller’s nomenclature, but revived Cerostoma Ltr., removing this 
synonym of Ypsolophus F. back to the Plutellidae (Hyponomeutidae), and in this 
diverse use of these absolute synonyms he has been followed by subsequent writers 
(vide Stgr-Rbl. Cat., Dyar’s List, etc.). A return must now be made to the synonymy 
established by Latreille and it will help to avoid confusion if the orthographic 
correction be now accepted :— 
Hyrsttorpaus F.,({Oxf-Camb. emend.) +Yvpsozoravs F. (1798) ; = +Ypsororza Ltr. (1796) ;
