11 cT 9 July 31-Aug. 5, Savonoski, Naknek Lake. This 

 species was described from Colorado by Uhler (1895) under the 

 name Teratocoris longicornis where it was taken on Car ex at 

 Steamboat Springs by C. F. Baker. Reuter (1909) was the 

 first to discover that longicornis Uhler was in reality identical 

 with Teratocoris saundersi Douglas & Scott (1869) described 

 from England. The species was later recorded from Scandi- 

 navia and Russia (Reuter 1875) and now with the present 

 material coming from Alaska the species would appear to be 

 holarctic in distribution. 



Usually the males and dark females are characterized by 

 having black along the median line of the head, pronotum and 

 scutellum. Certain male specimens have the scutellum entirely 

 black. The females may be entirely green but in such spec- 

 imens the second antennal segment, apices of femora, base and 

 apices of tibiae are distinctly reddish. 



Teratocoris herbaticus Uhler bears a close resemblance to 

 saundersi D. & S. and after a study of a co-type specimen ( 9 ) 

 from Ungava Bay, Labrador, the writer wishes to remark on one 

 or two distinguishing characters although Reuter (1909) has 

 pointed out the chief differences between the species. In the 

 female herbaticus, antennal segment I is shorter (length .43 

 mm., width .142 mm.) than in saundersi (length .57 mm., 

 width .128 mm.). In a male specimen of herbaticus from Ft. 

 Chimo, Labrador (L. M. Turner), the length of segment I 

 (1 mm.) is shorter than in the male of saundersi (length 1.23 

 mm.), the thickness of the segment (.114 mm.) being the same 

 in both specimens. In the male herbaticus there is in addition 

 to the median discal stripe a prominent fuscous stripe on each 

 side of the pronotum which extends back from the anterior 

 angles half way to the basal margin of the disk, being suffi- 

 ciently broad to cover the outer margin of the callus. The 

 pubescence appears heavier and more distinct in herbaticus 

 Uhler than in saundersi D. & S.
