23. D. cervicalis, Lee. — Has similar habits to the preceding, but is less abundant. 



24. D. xanthomelcena, Dalm.— Common on beets and other Chenopodiaceous plants, 



the leaves of which it riddles with holes.' 



25. D. crenicollis, Say. — One of the 5-lined flea-beetles that occur here in moderate 



numbers ; is also occasionally taken on beet leaves at Lincoln, Nebr. 



26. Systena frontalis, Fab. — Found feeding upon beet leaves ou the College farm, Lin- 



coln, Nebr. ; also on the leaves of Hibiscus militaris at West Point, Nebr. 



27. S. tceniata, var. blanda, Melsh. — A very numerous species in all parte of the State 



from which beet-feeding insects have been received. It literally riddles the 

 leaves of beets with pit-like holes, in some instances entirely destroying the 

 leaves of quite large plants. I have also taken it upon white clover, purslane, 

 and amaranthus. This is liable to be one of our most destructive beet insects 

 here in the West, especially in Nebraska. 



28. Psylliodes convexior, Lee. — Another of the flea-beetles that is very abundant on 



the leaves of beets in some portions of Nebraska, and which works in a some- 

 what similar manner to the preceding. 



29. Clicetocnema denticulata, Illig. — I found still another of our small flea-beetles at 



work on the beets growing on the State farm here at Lincoln, although in much 

 fewer numbers than either of the two species preceding. 



30. Epitrix cucumeris, Harr. — This small flea-beetle was found to be quite abundant 



at Ashland, Nebr., where it was taken by Mr. T. A. Williams, upon the potato, 

 Solanum nigrum, and the beet, the leaves of all of which were more or less 

 closely riddled with holes. 



31. Epicauta pennsylvanica, DeG. — This black blister-beetle injures the leaves of quite 



a number of plants, prominent among which are the potato, u pigweed," and 

 beet. It has been received at the station from central and western Nebraska 

 as one of the most destructive insects attacking the plant. 



32. Epicauta cinerea, Forst. — Another of these blister-beetles was found here at Lin- 



coln by Mr. Herbert Marsland, who said it almost ruined a small bed of beets 

 growing in his garden. I have also collected the same species from one of the 

 wild beans and several other native plants. 



33. Epicauta maculata, Say. — This insect has been received from Medicine Lodge, 



Kans., and from Grant and Neligh, Nebr., where it was found to injure the 

 sugar beets by feeding on the leaves. It is a very common insect here in the 

 West upon quite a number of the Chenopodiaceous plants, and especially upon 

 the various species belonging to the genera Chenopodium and Atriplex. 



34. Epicauta vittata, Fab.— This striped blister-beetle is also a beet insect; and has 



been received from Ogalalla, this State, where it was reported as doing much 

 damage to sugar beets. It also is quite a general feeder. Among its food plants 

 are to be mentioned the SolanaceaB, some of the Legutnmosse, and I have found 

 it to be quite destructive to several of the Sagittarise. 



35. Epicauta cinerea, var. marginata. — This large black blister beetle also frequently 



gathers upon vegetables of different kinds in the semi-arid regions east of the 

 Rocky Mountains, but chiefly upon beans. I have taken it on beets once or 

 twice here in Nebraska. 



36. Cantharis nuttalli, Say. — During the late summer and early fall of 1888 this in- 



sect was very destructive to garden plants, beets included, in the Black Hills 

 of South Dakota. It also abounds in the western and northwestern parts of 

 Nebraska. 



37. Colaspis brunnea, Fab. — This small leaf beetle, which appears to be quite a gen- 



eral feeder, has been taken on several different occasions upon the beet both by 

 myself and different ones of the field agents, and also by some of the correspond- 

 ents. 



38. Epiccerus imbricatus, Say.— The Imbricated Snout-beetle has been known to attack 



the beet among the many other plants upon which it feeds. It is a general 

 feeder.
