10 CONTKIIU riONS TO CANADIAN l*AL>:ONTOLOOY. 



Cercopis grnndesceiis. 



PI. I, fig. 2. 



A stouter species than C. tiein^tjai and somewliat larger. Only one 

 of the tegmina is preserved, but that is nearly complete. It is more 

 shouldered near the base, the costa beyond less arched, and at apex 

 is apparently more symmetrically rounded, theextreme apex apparently 

 lying at just about the middle of the wing. The radial and ulnar 

 veins fork considerably earlier than there, the radial a little beyond, 

 the ulnar a little before, the middle of the basal half of the wing ; as 

 in C. selwyni, the principal veins become obsolete or subobsolete 

 before their termination, but both branches of the radial may be seen 

 to divide into fine forks next the margin, traceable only by favorable 

 light as pallid threads, and similar oblique off-shoots run from the 

 upper branch to the costa in the apical half of the wing. The general 

 color is but little darker than the light gray stone on which it occurs, 

 and is nearly uniform, but a faint darker cloud traverses the wing just 

 beyond the middle. It is profusely punctate, the puncta much the 

 largest at the base and growing gradually finer, somewhat more ap- 

 proximated, and slightly less distinct in passing down the wing.

Palecphora Scudder. 



Palecphora Scudd., Tert. Ins. N. A., 324 (1890). 



This group was established on half a dozen very common species 

 found at Florissant, Colorado, but not one of them can compare in 

 size with the species here recorded, which is very imperfect, but 

 seems to be nearly allied to this group . 



Palecphora sp. 



PI. I, fig. 7. 



It is iinfortunate that this species is so poorly represented, for it is 

 perhaps the largest insect that has been found in the British Columbia 

 tertiaries . It shows the overlying tegmina and Avings, the separa- 

 tion of the obverse and reverse having torn the former so that only a 

 portion of each can be seen. Perhaps by removing the overlying 

 portion on each, the whole of the tegmina might be exposed on one, 

 the whole of one of the wings on the other. Enough is preserved in
