defined, and beneath the punctures are paler or quite uncolored. 

 The edge of the abdomen beneath is plainly marked with black 

 points at the incisures in ijeneifrons, while in bijvgis these black 

 points are nearly or quite absent. In size these species present 

 about the same range : from 65 to 9 mm. 



This species seems to be an inhabitant of the arid plains bordering 

 the Rocky Mountains. I have taken it wherever I have collected 

 in such situations in Colorado and Utah, and have received speci- 

 mens taken by Prof. Wickham at Carson City, Nev. Dr. Uhler 

 records it from as far east as Dakota and Nebraska and Prof. 

 Osborn from Iowa. 



Hoinoeinns graniinicus Wolf. 



This is the smallest species of Homoemus known to me. The 

 males in my collection measure 4h mm. in length, the females 6 mm. 

 In color and markings it closely resembles bijugis, but may be dis- 

 tinguished by the more gently curved osteolar canal, a somewhat 

 variable character however, and the form of the genital segment 

 in the male, which is regularly arcuated in gramniiciis, and trun- 

 cated or feebly concave in bijugis. In gramniicus the head is nar- 

 rower anteriorly, less convex, of a deep black color, hardly bronze- 

 black, as in bijugis, and the ))unctures are finer. The broad, pale 

 submarginal vitta is present as in bijugis. The pronotum differs in 

 having the humeri decidedly more prominent and subacute. On 

 the scutellum the lateral brown vittse are less curved within and 

 are discernible to the lateral margin, which is hardly true of bijugis. 

 The males in my possession are as clearly marked as are the females, 

 which is not the case in the allied species. 



Tliis species is more southern in its range than ucneifrons and 

 bijugis. It occurs from North Carolina south to Florida and west 

 to Texas and Mexico. My own specimens were taken in Kansas 

 by Mr. Crevecouer. It is also included in Gillette and Baker's 

 List of the Hemiptera of Colorado.

Dr. Uhler's description of this species seems to be incomplete, as 

 it fails to mention the size of the species or the locality of capture. 

 I have seen nothing that would answer to this description, and it 

 has never been mentioned l)y later writers on our Hemiptera. It 

 would seem to be rather closely allied to gramniicus.
