310 TEHTIAEY INSECTS OF N iRTH AMERICA. 



apically, so that the last two segments are much narrower than the preced- 

 ing. Tlie transverse thorax, as in the preceding species, is shghtly shorter 

 than the unusually large scutellum. The tegmina are considerably more 

 than three times as long as broad, the veins and cross-veins rather heavily 

 marked ; there are four apical cells, which are more than twice as long as 

 broad. The venation of the upper half of the hind wings (all that is pre- 

 served) is precisely the same as that of T. simplex of Europe, excepting 

 that the lower cross-vein is strongly oblique instead of transverse.

 of tegmina, 3.1-3.5 (?)""" ; breadth, 0.85-0.85 (?)""".

S^Thamnotettix fundi. 



PI. 19, Fig. 20. 



Head roundly angulate in front, the thorax small. Tegmina slender, 

 elongate, surpassing a little the abdomen, about three and a half times 

 longer than broad, the costal edge nearly straight, the longitudinal veins 

 few, distant, and feint, the substance of the wing being slightl}^ coriaceous, 

 or only partly diaphanous, as in our green and unicolorous living species. 



Length of body, 2.85"" ; tegmina, 2.65"" ; width of body, 0.85"" ; 

 tegmina, 0.75™". 



Florissant. One specimen. No. 3412. 



CICADULA Zetterstedt 



No fossil species of Jassida have yet been referred to this genus, and 

 the present reference of a somewhat obscure species is by no means 

 definite. 



CiCADULA SAXOSA. 

 PI. 6, Fig, 26. 



A species is indicated of about the size of our C sexnotata, but with 

 more opaque tegmhia. Only the part of the head between the eyes is pi-e 

 served, giving it a more distinct and quadrate appearance than would be 

 otherwise the case ; the front is broadly rounded. The thorax is more than 

 twice as broad as long and the posterior angle of the scutellum is slightly 

 more than a right angle. The tegmina are opaque, showing scarcely any 

 veins, and these only longitudinal, the suturaclavi terminating in the middle
