XIV. HEMIPTERA OF THE FAMILY MIRID^. 



Harry H. Knight, 

 University of Minnesota. 



Only thirteen species of Miridas have heretofore been 

 recorded from Alaska. Heidemann (1900) records ten species 

 which were collected by the Harriman expedition. Of these, 

 seven species were European forms which were known to extend 

 their range into North America. Three species, Mecomma 

 gilvipes, Irhisia sertcans, and Lygiis approximatus were originally 

 described from Sitka by Stal (1858). Orthocephalus saltator 

 (Hahn) was recorded from Alaska by Uhler (1886) but appar- 

 ently in error for the writer has seen specimens of an Irhisia sp. 

 taken in Alaska which bear the above name in Uhler's hand- 

 writing. No specimens of Orthocephalus saltator (Hahn), col- 

 lected in North America, are to be found in the U. S. National 

 Museum collection or the Uhler collection which is included 

 there. 



The present list enumerates eight species of which one has 

 not before been recorded from the Nearctic region, two of 

 which are new records for Alaska, and one new species. With 

 the present list a total of sixteen named species of Miridse are 

 known to occur in Alaska.

 inally described from Sitka by Stal (1858). Heidemann (1900) 

 records "numerous specimens" from five different localities in 

 Alaska. The male of this species is very similar to the same sex 

 of the European Mecomma ambulans (Fallen) which Uhler
