(WitH DESCRIPTIONS OF NEW GENERA AND SPECIES OF HEMIPTERA 
BY JOHN Scorrv.) 
T am requested to prefix a few words to the following descriptions 
of Corsican Hemiptera by Mr. Scott, who is at present in Spain. The 
new species here published were taken by me in the summer of 1870. 
Antipalocoris seems the most worthy of remark. It belongs to the 
Notonectide, and is allied to Anisops niveus, Fab. Both species occur 
in the rivers of Corsica, the Antipalocoris abundantly, swimming in 
small shoals, like fishes, against the current. Amisops, I believe, has 
only been noticed hitherto as African. Its pearly-white hemelytra give 
it the appearance of a young Notonecta. The male is furnished with a 
conspicuous frontal horn. Of the other Aquatilia, I noticed a Naucoris 
(in the larval state), probably parvulus, Fieb., Limnobates, Velia 
(winged), Hebrus, Sigara, swarming at the edges of rivers and ditches, 
Plea, Ranatra, and Hydrometra naias, De G. Of other Hemiptera, the 
most remarkable were Cantacader Staudingeri, Bar., at roots of grass, 
Campoloro ; Harpactor hemorrhoidalis, Fab., which is also the commonest 
species in Algeria ; Colliocoris niger, Fieb., and C. griseus, Rossi ; Holo- 
trichius (sp. ?), in larval state, living on elm trees, and preying on the 
innumerable larve of Galeruca calinariensis, L.,and clothed, like Reduvius, 
in a sort of grey frieze, composed of particles of dust ; Pirates strepitans, 
Ramb.; Nabis viridulus, Spin., on the tamarisk, found also in the Ca- 
margue, near Arles; Pyrrhocoris egyptius,L.; Lygeus apuans, Rossi, 
on mountain sides ; Lygeosoma reticulata, H.-Sch. ; Nysius senecionis, 
H.-Sch.; Puromius leptopoides, Bir.; Henestaris, doubtless the same as 
the British species; Ophthalmicus siculus and O. distinctus, Fieb., the 
former throughout the island, the latter on sandy grass-plats near the 
sea; Aoploscelis bilineatus, Fieb., in marshes of the Campoloro, known 
only as Corsican ; Megalonotus, all the British species, and niger, Fieb.; 
Scolopostethus cognatus, Fieb., Corsican only; Trapezonotus Ullrichi, 
Fieb., Dieuches pulcher, H.-Sch., D. Sphragadimium Am., and D. luscus, 
Fab., all equally abundant ; Rhyparochromus Rolandri, L., and R. vul- 
garis, Schill., and others of the genus; Beosus quadratus, Fab., B. 
saturnius, Rossi, and B. Douglasi, Fieb. (I know not whether the last 
has been described; it was discovered during my first visit to the
