will try to get rid of the ant, when instantly a few more will take 

 hold. In the struggle the insect will soon be on its back, when 

 in a moment it will be just swarming with ants. 



There is no putting out any bait or traps for insects. The ants 

 devour everything, as I have found to my sorrow, as I had no 

 luck with small bait — I tried a dead chicken. In a few days the 

 ground for yards around it was just alive with the pests. They 

 were dragging away every living thing, including perfect insects 

 and larvae that they could get hold of. They cleaned up every- 

 thing. I have seen them attack little chickens that were not more 

 than a day or two old and gather so thick on feet and head, that 

 the poor little things would soon give up and be on their back. I 

 have to watch the specimens I have collected very close for fear 

 they will get at them — they did eat up a box of Diptera fo me. 



REMARKS ON LIST OF THE HEMIPTERA OF COLORADO.^ 



By Carl F. Baker, Auburn, Ala. 



AHnyas pal/ens Sx.3.\. , p. 23. — This is the Geocoris pallens iox 

 which several records are given on the same page. 



Corythucafusci^era Stal, p. 57. — Several species were confused 

 under this name, as shown by subsequent determinations by Dr. 

 Uhler. Whether this is the species occurring so commonly on 

 Cnicus, at Fort Collins, remains to be determined. 



Helicoptera fiorida Walk., p. 69. — According to Dr. Uhler 

 this determination is erroneous, the species not hemgjloridcs. 



Pissonotus pallipes Van D., p. 69, and others of Van Duzee's 

 Delphacids mentioned on this page are manuscript species and 

 have not, up to the time of this writing, been published. 



Pachynopsis Uhler, pp. 71-72. — This genus is synonymous 

 with Macropsis Lewis. 



Idiocerus interruptus G. and B., p. 74. — The record for this 

 species, on page 75, was dropped under / distiiictus, and is 

 '■ P'ort Collins, September 26th on elm (Baker), and September 

 on grass (Gillette)." The latter occurrence was probably acci- 

 dental. This "species" is of doubtful validity.
