324 TERTIARY INSECTS OF NORTH AMERICA. 



and the whole of the clavus obscure. The head, thorax, and scutellum 

 appear to be uniformly and deeply sulcate (or carinate, if No. 9374 is an 

 obverse). 



Length of body, 15.5 mm ; of tegmina, 14 mm ; breadth of thorax, 5.5 mm ; 

 combined tegmina, 10'". 



Named for Prof. E. D. Cope, of Philadelphia, the distinguished and 

 versatile paleontologist and collaborator of the Hayden Survey. 



Florissant. Two specimens, Nos. 9374, and of the Princeton Collec- 

 tion 1.903. 



2. LOCKITES WHITEI. 

 PI. 21, Fig. 17. 



The single specimen and its reverse represent the dorsal surface of an 

 insect with closed wings. The head is relatively broader than in the last 

 species, with a similar though much slighter mediodorsal sulcation ; the 

 ocelli appear to be nearer together than to the eyes. The body is black, 

 and the tegmina dark fuliginous, but permitting the black abdomen to be 

 seen through them ; the distal half appears to be uniform, but the basal 

 half to be transversely banded by broad darker bars, between which and 

 between the basal bar and the base the tegmina are slightly lighter than the 

 normal ground, accentuating the bands. 



Length of body, 13.25 mm ; tegmina, 12 mm ; breadth of thorax, 5 mm ; 

 combined tegmina, 7 mm . 



Named for niy colleague, Dr. C. A. White, one of the paleoutological 

 collaborators of the Hayden Survey. 



Florissant. One specimen, Nos. 8313 and 8314. 



PALECPHORA gen. nov. (rraXaio?, H(popa). 



Allied to Triecphora in neuration, but with a more slender habit and 

 relatively far smaller clavus. Head suborbicular, about half as broad as 

 the thorax, the front well rounded, in no sense angulate, with a slight longi- 

 tudinal carina; ocelli posteriorly placed, much nearer together than to the 

 eyes. Thorax rather broader than long, the front and posterior margins 

 truncate, the sides angulate, so as to be as a whole transversely hexangular, 

 but more or less rounded, so as often to appear suborbicular; marked indis-
