122 THE CANADIAN ENTOMOLOGIST. 



Schrank, 1781. In Dalla Torre's Catalogiis Hymenopterorum, 1894, p. 

 152, this species is given as Athalia spinariim (Fabr.) Leach. As Konow 

 has indicated (Gen. Insect, and other references) spmariim Fabricius is a 

 synonym oi colibri Christ ; but Teiithredo salicis Schrank, 1781, is not the 

 proper name as might be surmised from Konow's synonymy, because in 

 mentioning Tefithredo salicis Schrank (a) cites as the species he is 

 describing Tenthredo salicis Linnaeus, 1761, which is now Pteronus salicis 

 Schrank, therefore, although he did describe a species of Athalia, did not 

 estabh'sh a vaHd name in the genus, having only misidentified the Linnean 

 species, Tenthredo salicis. The synonymy of this species would be as 

 follows : 



Athalia colibri (Christ) Konow. 



Tenthredo salicis Schrank, 1781 (not Linnaeus, 1761). 

 " spinaruni Fabricius, 1793. 

 " centifolice Panzer, 1795. 

 The subspecies and varieties as well as the biography have been 

 omitted. 



EuuRA Newman versus Cryptocampus Hartig. 



The genus Cryptocampus Hartig (b) was published in March, while 

 the genus Eimra Newman (c) was published in January. Cryptocampus 

 Hartig must, therefore, fall as a synonym of Eiiiira Newman. 



Arge Schrank versus Hylotoma Latreille. 



Rev. Herr F. W. Konow (d) replaces the generic name Hylotoma 

 Latreille by Arge Schrank with the following words : " Statt des Gattungs- 

 names Hylotoma Latr. muss der oblige altere Name eintreten." The two 

 names in question were proposed in works dated the same year. Arge 

 Schrank, in Fauna Boica, Vol. 2, part 2, 1802, p. 209 and pp. 226 to 229; 

 Hylotoma Latreille, in Hist. Nat. Ins., Vol. 3, 1802, p. 302. Arge was 

 founded on six species arranged in the following order : Tenthredo 

 ustidata Linn., T enodis Linn., T ciliaris Linn., Arge rosincola Sck., A. 

 bicolor Sck., and A. berberdis Sck. Hylotoma was founded on one 

 species, T. roscp. Linn., which is given as an "example."
