614 ( — ). Tetraphleps canadensis Provancher, 1886, 90. 



"Black with testaceous elytra. Head long and narrow, the epistome 

 (tylus?) reaching beyond the cheeks. Antennae less than half the length 

 of body, second segment longest, the last two fusiform. Elytra of a brown- 

 ish shade towai'd middle, with a very long cuneus ; membrane more or less 

 obscure with four very distinct longitudinal veins. Under side black.

"A single specimen (female) taken by us at Cap Rouge." 



The above is a free translation of the original description. 

 Except in the greater length, it will apply in a general way to 

 either T. americana or T. osborni. 



IV. Orius 72 Wolff, 1811, IV. 



Very small oval or oblong-oval finely pubescent species hav- 

 ing the head never longer than wide across eyes ; beak not pass- 

 ing front coxae, its first joint not reaching eyes ; joint 1 of an- 

 tennae reaching tip of tylus, 2 swollen toward apex, especially 

 so in male, not longer than width of vertex; 3 and 4 linear, 

 subequal, together but slightly longer than 2 ; pronotum trape- 

 zoidal, its basal margin feebly sinuate, front margin truncate, 

 disk finely rugose and with but a faint transverse median 

 groove, sides almost straight, finely margined ; scutellum with 

 basal portion strongly convex, apical portion flat, in our species 

 very finely rugose; elytra entire, passing tip of abdomen by 

 half the length of membrane, both cuneus and membrane quite 

 large ; hind coxae approximate ; osteolar canal long, continued 

 as a narrow obtusely curved carina as far as the base of the

 our territory. 



KEY TO EASTERN SPECIES OF ORIUS. 



a. Basal joint of antennae and femora wholly or in great part piceous; 

 elytra in part black. 615. INSIDIOSUS. 



ua. Antennae and legs wholly pale; elytra almost wholly pale straw- 

 yellow, the cuneus slightly tinged with fuscous. 616. pumilio. 



615 (864). Orius insidiosus (Say), 1832, 32; I, 357. 



Oblong-oval. Black, shining, minutely pubescent; elytra yellowish- 

 white or pale straw-yellow, the cuneus, tips of corium and embolium, and 

 sometimes (tvisticolor White) the entire clavus dark piceous-brown ; 



T -'This generic name has priority over Triphleps Fieber (1860. 266) under which 

 our species have been previously placed.
