THE CANADIAN ENTOMOLOGIST. 121 



Tenthredo (Selandria) cethiops Eversmann (o) is described as 

 belonging to a group of species having " a. Area lanceolata petiolata, 

 ■^Alae posticae cellula discoidali carentes/' which does not apply to 

 Califoa. 



Monostegia antipopa W. F. Kirby (p) may well be considered as a 

 synonym of Caliroa ( Eriocampoides) cerasi (Linnteus) Kirby (q), to the 

 contrary notwithstanding. Examination of the type of Kirby's species 

 failed to disclose differences other than the venation of the hind wings, 

 which is not reliable. 



Tenthredo cerasi Peck (r) is, as Dr. MacGillivray has pointed out, a 

 synonym of the Linnean species. 



The synonymy of this species expressed below will serve to indicate 

 the different names under which the species has been referred to. For a 

 bibliography of the species up to 1894 one may consult Dalla Torre's 

 Catalogus Hymenopterorum, Volume one. Since then a number of 

 authors have referred to this species, and the damage done by it in both 

 the palasarctic region and in Australia. Many of these are merely records 

 of occurrence without much value. Some also reproduce the figures 

 given by Mr. C. L. Marlatt (s). To assure themselves of the identity of 

 their insect, entomologists will do well to consult Dr. MacGillivray's 

 table (t) to the species of this group, and Marlatt's figure one. 

 Caliroa (Eriocampoides) cerasi (Linnseus). The common pear slug.
