The species are small, seldom over 4 and never over 7.5 mm. 

 in length. The males have the beak stouter, more coarsely sculp- 

 tured and usually less shining, with the antenna? inserted nearer 

 the apex than in females. For the most part they live in the buds, 

 flowers, fruit and seeds of plants, though a few breed in galls. 

 The larvte pupate in the feeding cell instead of entering the 

 ground.

Fall, in the paper cited under M<t</<l<tlix. reviews some of 

 Dietz's species and describes a number of additional ones. 

 Eighteen genera are ascribed to the tribe by Dietz, 13 of which 

 are represented in our territory. The following is his key modified 

 and abridged.
