tlandlirsoh] CANADIAN FOSSIL INSECTS 129 



The portion preserved measures 17™° in lengtli, and permits the 

 assumption that the total length of the wing may have been more 

 than 20™™. 



The radius and media are nearly parallel with each other, and at 

 the first third of the wing are united by a cross-vein. The cubitus 

 is distinctly curved, and in about the middle of the wing is joined 

 to the media by a sloping cross-vein. At half the distance between 

 the latter and the radiomedial cross-vein, the cubitus bifurcates into 

 a large fork, which encloses a somewhat biscuit-shaped cell. The 

 posterior branch of the cubitus is connected with the first anal vein 

 by a cross-vein, the former being very strongly arcuate, while the 

 two succeeding anal veins are straight. Here and there the marginal 

 vein is well preserved, and from the radius to thj first anal vein, 

 especially between the two long veins, it forms a simple curve, while 

 between the first and second anal veins, the curve is sigmoid. 



There is no doubt that this species belongs in the genus Aphro- 

 phora in the strict sense, yet to-day this genus includes only 

 numerous small forms. 



An indistinct impression of a front wing (without anal area), 

 likewise 17™™ in length, from Tranquille river, may also be referred 

 to the cercopids; as well as a small fragment of a wing from the 

 Horsefly mine, but neither can be accurately determined. 



To the auchenorrhynchous homopters also belongs a form identi- 

 fied by Scudder as Coelidiia columhiana. (Similkameen.) 



AphididcB : — 



Shendphis quesneli, Scudder. (Quesnel.) 

 Lachnus petrorum, Scudder. (Quesnel.) 



One wing described by Scudder as Planophlelia gi>gantea (Simil- 

 kameen), and six fragments from the collection under discussion are 

 so imperfectly preserved that, not even /the order in which they 

 belong can be determined with any degree of certainty.
