16 (1). Membrane with but one areole, the vein mostly parallel with 

 the suture. Elytra destitute of an embolium and cuneus. Pro- 

 thorax without an apical stricture. First tarsal joint long. 

 Arolia none. 1. Lygaeoscytinae 



Of these, the subfamily Lygaeoscytinae is Australian ; the sub- 

 family Bothynotinae is confined to the Old World ; the subfamily 

 Phylinae is equivalent in our fauna to my Phylini, Bryocorinae 

 to my Bryocorini, and Cylapinae to my Cylapini. Renter's sub- 

 family Heterotominae is the same as my Orthotylini, but his 

 typical division Heterotomaria was first founded as Litosomidae 

 by Douglas and Scott in 18(i5 ; but their genus Litosoma being 

 a straight synonym of OrtJiotylus Fieb., the tribe, or division of 

 Renter, must be called Orthotylini and the subfamily Ortho- 

 tylinae. Renter's Macrolophinae embrace my Dicyphini (Macro- 

 lopharia Kirk., 1906 is antedated by Idolocoridae Dougl. and 

 Scott, 1865, the typical genus Iclolocoris Dougl. and Scott, 1865, 

 being a synonym of Dicyphus Stal, 1858), and my Hallodapini 

 which is equivalent to Cremnocephalaria Rent, (first established 

 a.s Eroticoridae Dougl. and Scott, 1865, the typical genus Eroti- 

 coris Dougl. and Scott being a synonym of HaUodapus Fieb., 

 1858). Lastly Renter's Mirinae include my Myrini, Capsini and 

 Horistini ; the latter, termed Restheniaria by Renter, was first 

 distinguished as Lopidae by Douglas and Scott in 1865, their 

 Lopus being equivalent to Horistus Fieb., 1861. It will be noticed 

 that Renter has entirely ignored the work of Douglas and Scott, 

 who were the first to break up the great family Capsidae into 

 smaller divisions. That their divisions were sometimes made too 

 limited in scope and were termed families is no reason for ignor- 

 ing them entirely. Renter uses the termination -ina for his sub- 

 families, which I have changed to -inae to make them conform to 

 modern usage.
