other coniferous trees, where they feed upon the stamiuate 

 flowers in which the eggs are laid. Dr. LeConte has said (1874, 

 391) that they represent an old and undifferentiated form which 

 "still clings to a very ancient and synthetic type of vegetation." 

 To the Coleoptera genuina they connect through the Pythidoe, to 

 which family they seem closely related both in structure and 

 habits.

 The subfamily Khinomacermae is represented in the Eastern 

 United States and Europe by a single genus, which does not ap- 

 parently reach Central America. 



I. RHIXOMACER Fab., 1787. (Gr., ''nose" -j- "long.") 



From Diodyrlvynchus Schonh., the other North American 

 genus, this differs in having the maxillary palpi filiform and 

 flexible instead of short and rigid. The beak is broader and more 

 flattened in front of the antennae, and the epipleurae are much 

 less distinct. The males of Rliinomaccr differ from the females 

 in having the front tibiae longer and slightly curved inwards, the 

 beak longer, more slender and less dilated at tip, and the fifth 

 ventral with a slight median fovea. Our three eastern species 

 have the pubescence longer and coarser than those from the west.
