eri/throceplialus (= Salda id. Enc. = O.frontalis, Friv. Hahu Wanz.), from 

 the South of France, Runielia, and the Euphrates ; 3. 0. ruficeps, Germ., 

 from the Cape; 4. O.flaviccps, Burin., from LUC.OU. b. Scutcllum pointed, 

 hemdytra yellowish white: 5. 0. lituratus, from Farther India (beyond the 

 Gauges) ; 6. 0. ochroptents, do. ; 1.0. siculus, from Sicily; 8. 0. angularis, 

 do. ; 9. 0. colon, from Farther India. B, Prouotum, almost longer than the 

 breadth, much narrowed in front, the sides sinuated ; the eyes almost en- 

 tirely projecting beyond the angles of the corslet ; 10. 0. plagiatus, from the 

 East Indies. II. Clavus, firmly soldered to the corimn ; 11. 0. albipennis, 

 (Sit/f/a), Fabr., from various parts of Europe ; 12. O. phteoptems, Germ., from 

 Southern Africa ; 13. O. atcr (Salda}, Fabr. ; 14. 0. steveni (Salda}, Euc., 

 from France; 15. 0. lineola, Ramb., from Andalusia; 16. 0. ullrichii, from 

 Austria and Hungary. III. Clavus wanting entirely : 17. 0. grylloides 

 (Cimex}, Linn. ; 18. 0. lapponicus, Zett., from Lapland ; 19. 0. dispar, Waga. 

 The position of the last two is uncertain ; the author suspects the last to be 

 made up of 0. grylloides <$ and nllrichii 9 ] 



In the nests of Formica rufa a small Antlwcoris is found abundantly, 

 which has been described as A. fonnicetorum by Bohernann. (Ofvers. K. 

 Vet. Akad. Forh. 1844, p. 158, No. 23.) It comes nearest to A. exilis, but 

 is distinguished by its inferior size, the corslet not wrinkled in front, and 

 the whitish membrane of the half-shards (hemelytra). In the nests of the 

 same Ant Mark el has discovered Microphysa myrmecobia, a new species, and 

 the second of this remarkable genus, which has been found in the nests of 

 Formica fuligiuosa also (Germ. Zeitschr. Ent. v, p. 262.) 



ARADITES. Leon Dufour (Ann Soc. Eut. Fr. ii, p. 447, pi. 10, f. 1) 

 has described as new two species of Aradus, found under the bark of fir 

 trees in the Pyrenees, A. dilatatus and A. ellipticus ; both of them, however, 

 are Linnean species, viz. A. corticalis and A. betula respectively. 



TINGIDITES. Fieber (Eiitoni. Monogr. p. 20) has investigated this 

 family thoroughly, and introduced not only many new species, but a number 

 of new genera. His arrangement is as follows : 



I. Sheath of the sucker lying free upon the breast ; head with horn-like 

 processes from the cheeks ; half-shards (hemelytra) : Gen. 1. Zosmemis, Lap., 

 6 species. II. Sheath lying between the leaf-like plates of the breast. 

 Netshards (sagena;) : A. Netshards without a distinct central field. Gcu. 

 2. Agrumma, Westw. (Piesma, Lap., Serenthia, Spin.), 5 species. B. Cen- 

 tral field of the uetshards distinct, flat or depressed. Gen. 3. Taphrostethus: 

 central field doubled ; clavus free ; prouotum slightly elongated behind, 

 five-ribbed: T. 5-costatus, new species, from the East Indies. Gen. 4. Cam- 

 pylosteira : central field running in a curve down the entire shard ; prono- 

 tum cut away in front: 4 species, e. g. T'mgis venia, Fall. Gcu. 5. 

 Orlhosteira .- central field straight, almost oblong-rhomboid, the inner rib 

 straight, parallel to the scam-edge; target of the pronotum pentagonal,
