A NEW TENTHREDINID. 



BY L. PROVANCHER, CAP ROUGE, QUEBEC. 



Genus Synairema, Hartig. 



This genus was detached from Tenthredo by Hartig in 1837, for an 

 insect described in 1793 by Panzer, under the name of Tenthredo rttbi, 

 found in Germany, Sweden, France, Tyrol, &c. In 1849, Bremi described 

 a new species found in Helvetia, which he named 6". alpina. It has not 

 yet been recorded as met with in America. 



Synairema differs only from Tenthredo by its lanceolate cell, which is 

 largely contracted in the middle, while in the last it is separated by a 

 straight nervule.
