UHLER OX INSECTS. 777 



As Ida elata Le C. 



One specimen taken running among the grass in tLe evening, near 

 Colorado Springs, August 10, and another from the vicinity of Carion 

 City, August 11. 



Eusattus retkulaius Say. 



Taken in considerable numbers on a dark sandy spot on the banks of 

 the Arkansas Eiver west of Canon City, August 11. Some of them were 

 snugly stowed away behind the loose bark around the base of a cotton- 

 wood tree, others were in the sand in holes or beneath chips, and still 

 others were upon or around the roots of a species of Eiii)liorhia growing 

 abundantly at that spot. I could not find them in any other locality? 

 although I searched carefully in many such places as seemed to be prom- 

 ising for their appearance. They hide during the bright part of the day, 

 but run about with great activity upon the approach of even in g twilight 



Eleodes tricostata Say. 



This species was quite common upon the i^lains in the region near and 

 west of Colorado Springs, August 10 to 16. ISTo specimens occurred to 

 me in any other locality. They were generally found beneath rubbish 

 in the ground, or hid away around the roots of yuccas and other plants- 



EUodes hispilahris Say. 



Not rare, but widely scattered. A large number of specimens might 

 have been secured by searching over a large extent of surface, but it 

 was quite rare to find more than two specimens at a single spot. It was 

 met with at all i^oints on the plains, from Colorado Springs to Caiion 

 City, August 10 to 16. 



EUodes ohsoUta Say. 



Common on the plains, beneath cow-chips and rubbish, everywhere 

 from Denver to Colorado Springs. I did not find it abundant south of 

 the latter place, and it was only rarely to be seen in the vicinity of Canon 

 City. Found August 16 to 18. 



Eleodes suturaUs Say. 



Met with only at Denver, August 8. But most likely the season was 

 too far advanced for it to be found elsewhere and in the usual numbers. 



Eleodes exiricafa Say. 



Quite common beneath rubbish in the vicinity of Colorado Springs, 

 August 13 to 10; but I failed to find a specimen of it north of this 

 region. 



Eleodes nUjrina Le C. 



Occurred sparingly beneath chips and rubbish in ]Manitou Park, Au- 

 gust 14, but was not seen in any other locality. 



Emhaphion muricatum Say. 



This monstrous-looking insect was found rarely, and only ou the hill, 

 side near Colorado Springs, August 10.
