Two of Mr. Morice's specimens have the propodeum 

 more or less red, which suggests that it might possibly 

 vary to a coloration similar to that of Olivieri. The 

 almost obsolete tooth on the intermediate trochanters and 

 the shorter apical process of the stipites of the armature 

 will distinguish it in any of its varieties. 



Myzine, Latr. 



Fifty-two species of this genus are already recorded from 

 the Palsearctic region, but notwithstanding this Mr. Eaton 

 has, I believe, succeeded in discovering two distinctly new 

 ones, and Mr. Morice one. In order to ascertain whether 

 these were really undescribed I have taken some trouble 

 to analyze the genus, and to get the species more or less 

 together into groups. I have no doubt that many will 

 prove to be varieties of each other. Radozkowski, Hor. 

 Soc. Ent. Ross., xx, p. 36, expresses the opinion that only 

 two species exist in the Mediterranean fauna, and that the 

 rest are all varieties arising from crossing between these. 

 Even this may possibly be true, but some of them are at 

 any rate easily distinguished structurally, and that being 

 the case I think it is better to treat them as distinct until
