Described from numerous specimens, taken at Sugar Grove, May 
15th, 1915, by Mr. Delong. We have specimens from Sugar Grove, 
1902 (Osborn), and Plummer’s Island, Maryland (taken July 31st, 
1906, by D. H. Clemmons). 
Genus Gargaphia Stal. 
Gargaphia Stal, Stett. Ent. Zeit., p. 324, 1862; Enum. Hem., Band. HI, p. 119 
et 124, 1873. 
The genus Gargaphia can be separated from the rest of the Tingitidae 
by the interrupted rostral sulcus between the meso- and metasternum 
by a prominent transverse, sinuous carina.
