 Iloma'mioi hijugh Uhlek, Hayden, Bull. Geol. Surv. Terr., Montana, 1872, p. 393.

 species in size and ornamentation. It has been collected near and on the 

 foothills and also at considerable elevations in the Kocky Mountains of 

 Colorado and farther north. 



Family CORIMELvENIDiE. 



CORIMELiENA EXTENSA. 



Corimelmia extenm Uhler, Proc. Ent. Soc, Phila., II, 1867, p. 155. 



One specimen was caught August 7. It is a common species near 

 the Paciiic coast, being found from Oregon to Lower California. Its 

 affinities are so close with C. alhipennls Eschscholtz, of Chile, that it 

 ma}^ prove to be only a modified form of that species. Some of the 

 specimens from California and Oregon have the stripe on the coriuiij. 

 tinged with rufous. 



Family CYDNID.F. 



AMNESTUS PUSILLUS Uhler. 



Amnestus pusillus Uhler, Hayden, Bull. (Teol. Hurv. Terr., 1875, p. 278. 

 Two specimens were collected August 13. This is a common low- 

 land species in Texas and the Southern States. 



Family PENTATOMID^. 



PODISUS CYNICUS Say. 



Podisnx cynicKS Say, Heteropt. Hemipt., N. Amer., 1831, p. 3. 



A male of this species was secured on August 11, and a female on 

 August ll. 



It has been found previously in Massachusetts, New York, Penn- 

 sylvania, northern New Jersey, Ohio, Indiana, Illinois, upper Mary- 

 land, Missouri, Virginia, and Colorado. 



PODISUS BRACTEATUS Fitch. 



Podisus bracteatm Fitch, Third N. Y. Eeport, 1859, p. 18. 

 Four specimens, one a female, were collected August 3 and 11. 

 This species is shorter and proportionally broader than the preceding 

 one, and it seems to be intermediate between P. cynieus Say and P. 

 crocatus Uhler. All the species vary in color, and somewhat in degree 

 of punctation on the upper surface. The middle of the sinuated 

 margin of the segment just anterior to the genitalia (male) is more 

 incised than in the preceding species.
