HEMIPTERA— HOMOPTERA— JASSIDES. 313 



CCELIDIA Germar. 



The only species of this group hitherto reported fossil is one described 

 below from British Columbia. To this we now add another species from 

 Wyoming. It is an American type l)est developed in the tropics, but not 

 unknown in the southern United States.

A pair of tegmina, in which most of the venation can be made out, 

 with a crushed body and crumpled wings, represent a species of Coelidia or 

 an allied genus, with rather broad tegmina. The veins of the tegmina are 

 nearly parallel to the gently arcuate costal margin, are equidistant from one 

 another, and are united by cross-veins near the middle of the apical half of 

 the tegmina, the lower ulnar vein, which runs only a little below the mid- 

 dle of the wing, forking at this point ; the upper of the apical areolets, how- 

 ever, is considerably shorter than the others ; the two ulnar veins are united 

 by a cross-vein in the middle of the basal half of the tegmina, while not far 

 from the middle of the tegmina the ulnar and radial veins are similarly 

 united. The tegmina do not taper apically, the extremity is rounded and 

 obliquely docked, and the sutura clavi is short. The hind wings are pro- 

 vided with an unusual number of cross- veins.

2. CCELIDIA WYOMINGENSIS. 

 PI. 4, Fig. 8. 



A dark species appears to be indicated, the head and thorax being 

 black and the veins of the tegmina heavily marked with dark fuliginous. 

 The tegmina are well rounded, about three and a quarter times as long as 

 broad, the costal margin regularly and pretty strongly convex ; the pedicel
