798 FAMILY XXIX. — MIRID^. 



clothed with suberect yellowish hairs. Joint 1 of antennae subequal in 

 length to two-thirds the width of vertex; 2 more slender than and two 

 and two-third times longer than 1 ; 3 two-fifths the length of 2, 4 slightly 

 longer than 3. Pronotum except calli, scutellum and elytra all trans- 

 versely rugose. Length, 4.3 — 4.6 mm. 



Wilmington and Whiteface Mountain, N. Y., July (Davis). 

 Paris, Me., June 10 (Frost). Georgetown, Colo., July 28 (Ger- 

 hard) . A species of northern distribution ranging from Quebec 

 and New England west to the Pacific. Described from Colo- 

 rado and Montana. Recorded also from New Mexico. But 

 little regarding its habits has been published, though it seems 

 to inhabit, for the most part, mountainous regions. Drake 

 (1923, 77) mentions it as occurring on grasses and weeds about 

 Cranberry Lake, N. Y. In the macropterous forms from Maine 

 and New York the hairs of hind tibiae are fewer and shorter 

 than the spines, while in the Colorado specimens at hand they 

 are about as long as the spines, and the middle of hind and 

 middle tibiae are vaguely dull yellow. In these characters those 

 from Colorado appear to be intermediate in form between 

 Knight's L. hirtus (1922a, 258) and Uhler's species. Van Duzee 

 states-- 1 that one specimen in his material "has the tibia? alto- 

 gether black with the long tibial hairs and male claspers of 

 hirtus, so the color of the tibiae cannot be relied upon in separat- 

 ing these forms." As the description of hirtus agrees otherwise 

 in every particular with that of hesperius, I regard Knight's 

 name as a synonym. 



838 (1118). Labops burmeisteri Stal, 1858, 189. 



"Oval. Blackish, opaque, clothed with silken yellow pubescence; 

 head with a transverse basal line, curved forward on both sides and in- 

 terrupted at middle, a spot beneath the eyes, cheeks, narrow pectoral 

 margins adjoining coxa?, and a wide annulus on middle of tibiae, sordid 

 yellow. Membrane wanting. Female, length 4.3 mm. ; width 2 mm." 

 (Stal). 



The above is a free translation of the brief original descrip- 

 tion. It is a palaearctic species, described from Kamchatka and 

 recorded in this country from the Adirondack region, New 

 York, Sudbury and the Abitibi region, Ontario, and Alaska. 



Tribe II. SEMIINI Knight, 1923, 497. 



This tribe also contains but a single genus which is easily 

 separated from others of the subfamily by the presence of a 



S3 Pan Pacific Entomologist, II, 1926, 163.
