lanst, as there are no "transverse bands" whatever. T. simulant seems 

 to be allied to the European apifurmiH. 



N B. — Mr. Hv. Edwards, who is studying this group, refers this 

 species to the sub-genus ISciapteron of Staudinger, and identities 

 Harris's marginatum, of which he has seen the type, as a form very 

 different in its characters, and sub-generically distinct from simuldns.

* I believe this to feed almost exclusively upon the pollen of the Cqmpositcp. 



** I have taken this in crevices of bark on trees during winter. 



*** Found also under boards and rubbish. 



Although the occurrence of these species upon the willows named cannot be 

 considered conclusive evidence of their having eaten of the foliage, yet the fact 

 is strongly suggestive. The species were collected, for the most part, during the 

 early twilight, a time when many species feed. Formerly the prairie fires, but 

 later the mower of the farmer, destroys each season's growth, consequently each 

 succeeding spring a fresh shoot takes its place, offering a tender morsel for the 

 leaf-eater. 



Another and equally interesting fact is the collecting of many Carabidffi, 

 Oerambycida.', Elateridae, Telephoridae, and Curculionida\ in the same localities. 

 a list of which will be given in a future paper. 



As the willows grow often interjacent, and the collecting was done with a 

 common beating-net. I am unable to distinguish the favorite of each insect.

A great numbei of the above-na/med species were frequently captured on Acer 

 nibrum, Lin., in a locality where willows are very scarce. F. G. SOFTAUPP.
