Adult. This was described by Scott from one example as 

 follows : 



Ting is pyrioidcs. Extremely like Tingis pyri in nearly every particu- 

 lar : and therefore it will only be necessary to point out the characters 

 which will separate them. 



Tingie pyri Fab. Disk of the elytra from the apex of the rhomboidal 

 cell with 5 transverse rows of irregular meshes. 



Tingis pyrioidcs. Disk of the elytra from the apex of the rhomboi- 

 dal cell with 3 transverse rows of irregular meshes. Pronotum, lateral 

 margins more upright than in T. pyri. Length I and 1/2 line. 



As a matter of information the original description of Tingis 

 pyri by Fabricius in Sy sterna Entomologiae (1775). p. 696, is 

 given as follows : 



Acanthia pyri thorace trialato, scutello foliato, elytris reticulatis, 

 basi gibbis. 



Habitat in foliorum pyri pagina inferiori, ea maculans. Prof. Herr- 

 mann. Caput parvum, albidum. Thorax alis tribus magnis, elevatis, al- 

 bis, f usco-reticulatis ; lateralibus compressis. carinatis, acutis; intermedia 

 globosa, breviora. Scutellum elevatum, foliaceum, acutum, album, ma- 

 cula fusca baseos. Elytra reticulata, alba, fusco-maculata, basi gibba. 

 Pedes albi. 



On the accompanying plate will be found figures of the egg, 

 nymphal stages, adult, anal claspers of male, ovipositor and 

 ovaries. Each ovary was found to consist of six tubes, some 

 of which were empty, while others contained mature and im- 

 mature eggs. The mature eggs in the oviduct showed slight 

 brown discolorations at the upper ends. As shown in the fig- 

 ure, a seminal receptacle was found slightly on the ventral 

 side of each oviduct. 



These lace bugs may be controlled on azaleas by spraying 

 with whale oil soap at the rate of 5 or 6 pounds to 50 gallons 

 of water. To be most effective the spraying should take place 

 shortly after the over-wintering eggs have hatched and should 

 be directed against the undersides of the leaves.
