to me in Clear Creek Canon and at Golden, August 5-7. One specimen 

 was taken west of Denver on August 9. 



Helochara Fitcb. 

 S. communis. 



Melochara communis Fitch, lus. N. Y. State Cabinet, 56. 

 Very common in grassy marshy spots in the bed of the creek which 

 passes through Denver, also in similar situations on the farms west of 

 Denver. Some specimens were of larger size than usual. On the east- 

 ern side of the continent, it is common in damp meadows from Maine to 

 Georgia. It is found also in Texas, and in my collection is a specimen 

 from ISIew Leon, Mexico. In Maryland, it sometimes swarms in the 

 grass adjacent to brooks and streams, and occurs in two varieties, the 

 less common one of which is mostly of a clear bright green. 



Tettigonia Geoff. 

 T. MeroglypMca. 



Tettigonia Meroglyphica Say, Jouro. Acad. Phila., vi, 313, No. 6. 

 Common in many parts of Colorado. I swept it from plants in Beaver 

 Brook Gulch, near Golden, in Denver, abundantly near Colorado 

 Springs, at Manitou, and in Manitou Park, and less common near the 

 mouth of the great canon of the Arkansas.
