TSTREOCORINJI. 



Genus Thyreocoris. 



Thyreocoris notatipennis. 



Corimelcena notatipennis, Stal, Rio Jan. Hem. i. p. 8 (1860). 

 Corimelcena chilocuroides, Walk. Cat. Het. i. p. 79. ii. 26 (1867). 

 Corimelcena ienninalis, Walk. loc. cit. p. 80. n. 29. 



Thyreocoris Daldorji. 

 Te^j/m Drt/^o;;/?;', Fabr. Syst. Rhyng. p. 144 (1803). 

 Var. Corimelcena pictula, Walk. Cat. Het. i. p. 80. n. 30 (186/). 



Thyreocoris hasalis. 



Odo7itoscelis basalis, Germ. Zeitschr. i. ^. 41 (1839). 

 Coritnelcena proxitna, Walk. Cat. Het. i. p. 80. n. 28 (1867). 



Thyreocoris integrus. 



Corimelcena intep-a, Walk. Cat. Het. i. p. 80. n. 27 (1867). 



Doubtfully distinct ; may probably be one of Stal's species 

 (c/. Rio Jan. Hem.), of which I have not seen typical speci- 

 mens. 



Thyreocoris invar ius. 



Corimelcena invaria, Walk. Cat. Het. i. p. 81. n. 31 (1867). 



The same observation applies to this as to the preceding 

 species (supra). 



Genus CURSULA. 

 Cursula, Walk. Cat. Het. i. p. 81 (1867). 



Cursula is allied to ChJcenocoris and represents that genus 

 with a laterally compressed body. I formerly described three 

 species as compressed examples of ChJcenocoris, which must 

 either now be placed in Cursula, or that genus sunk as a 

 synonym of Chlcenocoris. The first course is followed. 



Cursula dissimilis. 



Chl<B7iocoris dissijnilis, Dist. Biol. Centr.-Am., Rhynch. Het. i. p. 310. 

 n. 2, pi. XXX. f . 3 (1889). 



Cursula compressa. 

 Chlcenocoris compressus, Dist. Biol. Cont.-Am., Rhyncb. Het. i. p. 310, 

 n. 3, pi. XXX. f. 11 (1889). 



Cursula arctata. 



Chlcsnocoris aretatus, Dist. Biol. Cent.-Am., Rhyuch. Het. i. p. 454.
