23. D. cervicalis, Lec.—Has similar habits to the preceding, but is less abundant. 
24. D. xanthomelena, 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 on the College farm, Lin- 
coin, Nebr.; also on the leaves of Hibiscus militaris at West Point, Nebr. 
27. S. teniata, var. blanda, Melsh.—A very numerous species in all parts 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, Lec.—Another of the flea-beetles that is very abundant on 
the leaves of beets in some portions of Nebraska, and which works in a soine- 
what similar manner to the preceding. 
29. Chetocnema 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. 
Epitric 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. 
Epicauta pennsylvanica, DeG.—This black plisierhectias injures the leaves of quite 
a number of plants, prominent among which are the potato, ‘‘ 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 isa 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 
ate to be mentioned the Solanacesx, some of the Leguminose, and I have found 
it to be quite destructive to several of the Sagittaric. 
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. 
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. ; 
Epicerus 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.
