THE CANADIAN ENTOMOLOGIST. 201 



segment, apical margin tiisiiiuate in the middle ; central lobes of sixth 

 segment dilated towards the apex, taken together much broader at apex 

 than the length of the segment, apical margin trisinuate in the middle part, 

 apical angles almost reaching apex of second genital segment ; first genital 

 segment twice as long as second, this not protruding between the apical 

 genital lobes, which are rather broadly distant and broader ihan long, 

 rounded on the inner side and shallowly notched on the outer side ; 

 dorsal genital segment almost truncate at apex, scarcely projecting beyond 

 apical margin of last connexival segment. 



Astoria, Oregon (coll. Heidemann); Yale, British Columbia (my coll.). 



The specimen from Yale is a brachypterous female ; it is of a more 

 grayish-black colour, the lateral margins of the pronotum are quite straight, 

 the corium is not longer than the scutellum, rounded at apex, and the 

 membrane is entirely wanting. It much resembles the brachypterous 

 form o( fiiger, but is larger, with the antennae and female genital segments 

 differently shaped. 



This interesting species belongs to the subgenus Qui/?ius of Stal, 

 distinguished by the very short rcstrum and the trapezoidal pronotum. 

 This subgenus is represented by three species in the palaearctic region 

 {A. parvicollis, Stal, from South-eastern Europe and the Island of Cyprus; 

 A. jjiirus, Bergr., from Austria, and A. brevtrostris, Horv., from Siberia), 

 and by two nearctic species [A. niger, Stal, and the above described new 

 species). They live on conifers ; unlike other Aradi, which are mostly 

 found under the bark, minis dwells on the twigs and needles of the live 

 trees. 



9. Mezira Jatnaicemis, n. sp. — Elongate, brownish piceous, abdomen 

 ferruginous, apical margin of connexival segments pale yellow. Head 

 about as long as broad, antenniferous spines short, slightly divergent, 

 first joint of antennae considerably passing apex of head, second joint 

 shorter than first, incrassated towards apex, third joint longer by a 

 half than the second, slender, a little incrassated at extreme apex, fourth 

 joint a trifle shorter than second, postocular teeth acute, not passing the 

 eyes. Pronotum almost straight at base, sides rounded, sinuated before 

 the middle, apical angles rounded. Scutellum slightly carinate in the 

 middle. Hemelytra ( 9 ) reaching base of sixth dorsal segment, corium 

 reaching the middle of second connexival segment, apical margin straight, 

 membrane blackish, with two subconfluent pale spots at base. Abdomen 

 scarcely broader than pronotum. Length, % , 6 mm. ^
