190 TERTIARY INSECTS OF NURTH AMERICA. 



The wing is tolerably clear, slightly infuscated next the costa with fuscons 

 veins. The neuration along the middle of the outer half of the wing is not 

 correctly given in the plate ; the vein above the lowest forked vein (con- 

 taining the fourth apical cell) is also equally but not so widely forked, and 

 it does not connect (excepting by a cross-vein) with the vein above, but 

 much farther toward the base with the vein below, its fork containing the 

 third apical cell. 



Length of body, d""" ; of front wing, 10.5°""; breadth of same, 4""°. 



Florissant. One specimen, Nos. 8422 and 13004. 



8. TINODES Curtis. 



The single species referred here provisionally is shown by its neuration 

 to belong elsewhere, and is merely placed here for convenience and for want 

 of a better place. Moreover two species have been found in amber. 



TiNODES (!) PALUDIGENA. 



PI. 15, Fig. 9. 



An interesting little species, apparently belonging near this genus, but 

 in which the neuration is even simpler, though being in large part obscure, 

 the species is placed here provisionally. The body is moderately slender, 

 the legs rather short. The front wings are not very slender, broadest in 

 the middle of the apical half, beyond which the wing tapers rapidly and 

 almost equally above and below to a rounded apex. Only the first and 

 third apical cells are present and both very large and with a long stalk, the 

 veins originating far toward the base. This alone shows it can not be a 

 Tinodes, but the anastomosis can not be made out. The hind wing is con- 

 siderably shorter than the front wing, broadest near the base, has a pretty 

 strongly curved costal margin terminating abiaiptly in a pointed apex, from 

 which the oblique apical margin retreating rapidly blends by one curve in 

 the inner margin ; the second and third apical cells only are present, of 

 about equal and considerable length, the latter nearly reaching the middle 

 of the wing; an interesting feature of this wing is a large spreading tuft of 

 dark hairs longer than the width of the thorax, springing from near the base 

 ■ of the costal area.
