EURITEA,—ACUTALIS, 1 13 
EURITEA. 
Euritea, Stal, Ofv. Kongl. Vet.-Ak. Forh. xxiv. p. 552 (1867). 
This genus closely resembles Phacusa, of which it is regarded by Stal as a subgenus ; 
it is distinguished by the fact that the tegmina have two discoidal areas. 
1. Kuritea personata. (Tab. VII. figg. 22, 22a.) 
Phacusa (Euritea) personata, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxvi. p-. 247°. 
Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.)—Co.omBia, Bogota 1. - 
In general appearance this species much resembles Phacusa dubia, but is easily 
distinguished by the venation and colour of the tegmina, 
2. Huritea munda. (Tab. VII. figg. 23, 23a.) 
Parmula munda, Walk. List of Homopt. Ins., Suppl. p. 152°. 
Phacusa (Euritea) nigripes, Stal, Ofv. Kongl. Vet.-Ak. Forh. xxvi. p. 2487. 
Hab. Mexico (Sallé!; coll. Signoret?); Guatemaua (Deby!), Cubilguitz in Vera 
Paz, Volcan de Atitlan (Champion). 
A very distinct species, of which we figure a specimen from the Volcan de Atitlan. 
ACUTALIS. 
Acutalis, Fairmaire, Ann. Soc. Ent. Fr. sér, 2, iv. p. 496 (1846) (part.). 
As here limited, this genus contains those species which have five apical areas to the 
tegmina and no discoidal area; occasionally one of the small areas at the apex of the 
internal or external margins is wanting or has the vein ill-defined, but this is very 
seldom the case, and the species cannot be confounded with Micrutalis, in which the 
veins are less marked, and in the great majority of species very inconspicuous. 
Fairmaire mentions Acutalis as having five apical areas, but says that one is often 
“ atrophied,” and he gives two figures (op. cit. t. 7. figg. 18 & 20; not 19, as he states 
in error on p. 496) which well represent the difference between Acutalis and Micrutalis, 
but refers both to Acutalis: throughout the Homoptera certain veins are often wanting 
in some examples of one species; but if the difference is constant throughout a whole 
species or group of species, those veins can hardly be spoken of as ‘ atrophied.” 
Micrutalis balteata forms a connecting-link between the two genera; but if its tegmina 
be examined, the differences will be at once apparent, and, with the exception of this 
and one or two allied species, the members of the last-named genus are very small 
and inconspicuous.
