 This subftimily was established by Dr. L. O. Howard, in 1894, and was based 

 upon my genus Signiphora, described in 1880, from specimens bred in Florida from 

 the purjile scale, Asjndiotus dtricola Packard. Many species have since been dis- 

 covered from different parts of the world, and the group, although at present rep- 

 resented by a single genus, has evidently a wide distribution. The species destroy 

 scale insects, Chcriihi', and the mealy-winged Hies, AJeurodUhe. 



Antenna; apparently 3-jointed hut in reality (i-joiuted, there being 3 minute ring-joiuts easily overlooked ; 

 wings with a long marginal fringe, the marginal vein long, about the length of the .subcostal vein, the 

 stigmal vein distinct but not long, the po.stmarginal vein ah.scnt ; middle tibia' with a large, lobed 

 apical spur, and with lateral spurs or strong bristles. 



Signiphora Ashmead (type .S'. Jliivojxdliala Ashni.).
