4. Eurycreon rantaUs, Guen. — The larva of this small Pyralid moth is one of our 



most destructive beet insects. It is the one usually known as the Garden Web- 

 worm ; and also attacks a number of other plants among which are the " Pig- 

 weed," the tumble weed, purslane, etc. 



5. Mamestra trifolii, Rott. — Larva quite common on beets; and sometimes doing 



considerable injury by gnawing away the leaves and the entire tops of small 

 plants. Also a purslane insect. 



6. Plusia brassica, Riley. — The larva occasionally attacks the beet, but more com- 



monly the turnip, cabbage, and other Cruciferse. 



7. Deilephila lineata, Fab. — Larva found feeding on beet leaves in Lincoln, Nebr., 



by Mr. H. Marsland. A very common purslane insect. 



8. Copidryas gloveri, G. and R. — Taken several times on the leaves of beets which it 



had eaten more or less. An abundant purslane moth. 



9. Agrotis, spp. — Several species of these " cut-worms" are occasionally quite de- 



structive to the beet while it is still small. They work more or less all summer, 

 but are most destructive early in the year. They cut off the plant just at or a 

 little below the surface of the ground. Some of them also work upon the leaves 

 above the ground. 



10. Leucania unipuncta, Haw.— The Army Worm, when it is abundant, does consider- 



able damage to beets and other garden plants by eating their foliage. 



11. Botis pesticata, Grt. — The larva of this moth is said to be quite destructive to a 



number of plants here in the West. "In 1873 we found the larvsB feeding 

 upon Helianthus, Ambrosia, potatoes, and beets, skeletonizing and ruining the 

 plants for miles along the Neosho Valley and throughout Kansas," writes Pro- 

 fessor Riley in the U. S. Agricultural Report for 1883. 



ORTIIOPTERA. 



12. Melanoplus femur-rulrum, DeG. — Occasionally injuring the leaves of beets and 



other vegetables. 



13. Jf. atlanis, Riley.— When common, a general feeder, at least upon the products 



of the garden and farm — beets of course included. 



14. M. spretus, Thos. — Attacks the beet during times of invasions. Sometimes en- 



tirely eating away the leaves and portions of root that protrude from the 

 ground. 



15. M. differ entialis, Thos. — When plentiful it occasionally does some injury to the 



foliage of the beet and other garden plants. 



16. M. bivittatus, Say. — Where beets are planted on low ground or are growing- 



close to some rank vegetation, it attacks their tops, but never does much 

 damage. 



17. Dissosteira Carolina, Lin. — Found feeding upon the tops of sugar beets during the 



month of July, at McCook, Nebr. 



18. Trimerotropis latifasciata, Scudd. — Taken in company with the preceding, also 



feeding on sugar beets. 



19. Spharagemon cequale, Scudd. — Several specimens were received during the sum- 



mer from McCook and Ravenna, Nebr., with the accompanying statement to 

 the effect that they fed on the sugar beet. 



20. Pezotettix olivaceus, Scudd. — I have seen this hopper in beet fields several times 



under such circumstances as led me to think it feeds upon that plant. It is also 

 quite partial to Helianthus and Chenopodium. 



COLEOPTERA. 



21. Diabrotica Yl-punctata, Oliv. — Quite common on the leaves of beets, which it in- 



jures by gnawing holes in them. 



22. Disonycha triangularis, Say. — The beetle feeds upon the leaves of beets and other 



Chenopodiaceous plants. Sometimes quite common here in the West.
