 C. nntauioides. 



Cimex nitiduloides Woiff, Icones Ciin., 98, pi. x, fig. 92. 

 During the month of August, a few specimens of this insect were 

 found near Colorado Springs, concealed among the roots of Yuccas and 

 of other plants growing on the plains near the foot-hills. The season 

 was particularly rainy, and snow or hail occasionally succeeded the 

 thunder-storms. Sudden cold had the effect to chase many insects into 

 sheltered i)laces, and the dense leaves and roots of the grasses and Yuc- 

 cas afforded an ever-present shelter to many kinds of beetles and bugs.

1. H. ceneifrons. 



Scntellera ceneifrons Say, Long's Esped., App., 299, No. 2. 



Specimens were swept from the rank, growing weeds skirting, or not 

 remote from, the water-courses. West of Denver, they occurred in 

 swampy spots near the South Platte River, and on the high table-land 

 near the foot-hills, where the irrigation-trenches water the farms. A few 

 ver}^ clearly marked specimens were beaten from bushes in Beaver 

 Brook Gulch and in Clear Creek Canon. 



In general, these western mountain specimens are not so dull colored, 

 nor so broad, as those which occur on the eastern side of the continent. 



2. a. hijugis. 



Homcemus hijugis Uhler, Fifth Ann. Rep. U. S. Geol. Surv.for 1871, 1872, 393. 



Not uncommon in the city of Denver, particularly on rank-growing 

 plants in damp situations. 



Subfam. EURYGASTRTN^. 



EURYGASTER Lap. 

 E. alteniatus. 



Tefyra alternata Say, Amer. Eut., tab. iii, p. 43, fig, 3. 



Common in Colorado, in September, in the region of the foot-hills. 

 Baron Osten Sacken collected a specimen in the Yosemite Valley, Cali- 

 fornia, in June, and another at Los Angeles, California, in March. The 

 species varies much in the amount of dark clouding and marbling on the 

 scutellum and corium, and also in the size of the dark spots on the con- 

 nexivum.
