STIKADERES (^Oreipa, Siprf)^ gen. nov. 



An insect is placed in tliis m^w generic category which appears l)y its 

 general aspect, moderately short antemise, and entire eyes to belong to 

 the gi-oup Tropideres. It is maiidy to Ije di.stingui.slied for the po.sition of 

 the prebasal prothoracic ridge, which is rectilinear and situate(| so far from 

 the ba.se as to be .slightly in advance of the middle of tlie prothorax, a 

 character which certainly occurs in none of our genera, and is apparentlv 

 uni(pie. The beak is unfortunately not well preserved, but is ap])arentlv 

 shoi-t, not greatly longer than the large, broad-oval, obliquelv longitudinal, 

 prominent eyes. The antenna' are a little longei- than tlie head and pro- 

 thorax together, rather stout, the middle joints not moic than twice as long 

 as liroad, scarcely larger at apex than at base, the three apical joints (piad- 

 rate or even broader than long, hardly broader than the preceding, the last 

 very bluntly rounded at tip, almost truncate. 



A single species is known and comes from Florissant.
