HEMIPTERA— nOMOPTERA— CERCOPIDxE. 337 



crossing the hinder margin of the thorax, but not involving- the pale 

 scutellum. The tegmina are marked at base by two very broad, dark, 

 longitudinal stripes, one following the costa for the basal two-fifths of the 

 wing, and here bent inward half-way across the tegmina ; the other, most 

 intense in color as soon as the scutellum is passed, and not extending so far 

 out as the costal patch, occupies the base of the clavus ; the pale inner base 

 of the coriuni is therefore nearly inclosed with dark Ijands; outside of 

 these basal markings, which extend nearly to the middle of the wing, is a 

 broad, transverse, equal, pretty sharply edged, subapical, dark band, most 

 intense in tone on the costal half 



This insect differs so much from the others that I suspect it will be 

 found necessary to separate it generically from them.

APHROPHORA Germar. 



Half a dozen species or more referred to this genus have been found 

 fossil in amber, and at Oeningen, Aix, Radoboj, and at Greith, in the 

 rocks; they have been mentioned or described by Berendt, Gravenhorst, 

 Germar, Heer, and Giebel. The single one here added, very imperfectly 

 known, is placed here only as the group giving its name to the subfamily. 



Aphrophora sp. 

 PI. 19, Fig. 10. 



To Aphrophora as typical of the subfamily I refer some imperfect 

 specimens which bear a certain general resemblance to Palecphora, but 

 which have a rounded front to the thorax, showing that they should be 

 brought in this division. None of them are perfect enough to enable one 

 to draw from all a ):)roper description, for they appear to have been fragile 

 insects. The structure of the legs appears to be as in Palecphora; the 

 tegmina to have been delicate and semi-transparent, and to have had a 

 large subapical costal cloud. 



Length of body, lO'""'; of tegmina, 8"""; breadth of thorax, 2.5""°.
