39. Cenirinua jtenicillus, Hbst. — Another of the Snout-bettles that attack the beets 



here in the West is the one known to the entomologist by the above name. It 

 gnaws small holes in the leaf-stem, and when numerous does considerable harm 

 to the plants attacked. Whether or not the insect breeds here I was unable to 

 ascertain. 



40. C.perscitus, Hbst. — Still a third species of weevil was found upon the beets grow- 



ing on the State farm. It is a much commoner insect than peniciUm, and works 

 in a similar manner upon the leaf-stem. 



41. Apion, sp. — This little Apion was taken on the leaves of beets here at Lincoln on 



two separate occasions. 



42. DoryplwralQ-hneata. Say. — The Colorado Potato-beetle was brought into my office 



at different times during the summer by those who reported its having been 

 captured on the leaves of beet which it was " certainly eating." 



HETEEOPTEEA. 



43. Blissus leucopterus, Say. — The Chinch Bug has quite frequently been taken by 



me upon beet tops in company with several others of the plant bugs. Whether 

 or not it was there only temporarily, I can not say; but suppose it was, since 

 all of our leading economic entomologists assert that its food-plants are limited 

 to the grasses. 



44. Piesma cinerea, Say. — A very common bug on the beet and various others of the 



Chenopodiaceous plants. Sometimes doing much damage to the leaves of the 

 former. 



45. Xysius angustatus, Uhl. — Another bug that often gathers upou the beet and other 



garden plants is what is called the False Chinch-bug. When numerous it 

 often does considerable harm to the plants which it attacks. It is also one of 

 the weed insects that enjoys a wide range. 



46. Geocoris ouUatus, Say. — The Large-headed False Chinch-bug, or Purslane Bug, is 



also much addicted to infesting the beet here in Nebraska. In fact it has been 

 . received from all over the State as one of the commonest of insects infesting 

 the beet. It is also a great weed bug. 



47. Trapezonotus nebulosus, Fall. — This bug also frequents the beet and several other 



Chenopodiaceous plants. It is especially partial to the Pigweed (Chenopo- 

 dium album) here in Nebraska. 

 4^. Emolethis arenarius. Linn. — Taken several times on the beet in company with the 

 precediug. This insect also is a frequenter of localities where Clienopocliam al- 

 o urn is growing. The species also occurs about the roots of " Stink Grass" 

 (Eragrostis major). 



49. Lygus praiensis, Linn. — Probably one of the most general feeders among the true 



bugs, and sometimes a very destructive enemy of the beet. It occurs through- 

 out the entire North American continent in the temperate regions. 



50. Eutlwctlia galeator, Fab. — This bug has also been taken several times ou the beet 



in the vicinity of Lincoln, Nebr. I have collected it also from the wild cucum- 

 ber (Ecliinocystis looata). 



HOMOPTEEA. 



51. Agallia siccifolia. — This little leaf-hopper, which seems to be especially partial to 



the different species of Amarantus and Chenopodium and allied weeds, is also 

 equally fond of the beet, at least such would appear to be the fact, judging from 

 the large numbers of the insect that are invariably to be found upon this plant 

 all through the summer. It occurs in all stages. 



52. Immature forms only. — Found in moderate numbers on the sugar beet at Grant, 



Nebr., a rather large leaf-hopper, which also occurs upon the Amarantus and 

 Chenopodium.
