Perania, n. gen. (Tyi)e P. dissociata.) 



Proboscis moderate ; palpi upturned to well beyond front; front with 

 large conical process, sharp at apex, and hollowed out on under side at 

 base, which is tuberculate ; eyes naked, fairly prominent ; vestiture 

 largely scaly ; thorax but slightly tufted ; abdomen tufted on basal 

 segments ; fore tibia smooth, without apical claw ; fore wing rapidly 

 broadening from base to apex, outer margin rounded, areola small, 

 diamond-shaped ; veins R, and R^ stalked, together with R5 from apex of 

 areole ; Mj from close to apex of cell ; Mj, M3 and Cu from lower angle 

 of cell ; secondaries with veins R and M from upper angle of cell ; Mg 

 and Cu from lower angle ; Mg parallel to M3. 



This genus approaches nearest to Achatodes Gn., in general structure, 

 but in outward appearance dissociata is widely different from A. zece. Har., 

 and has in fact much more superficial resemblance to the Stibadiutn 

 group. 



Perania dissociata, n. sp. 



$ . — General ground-colour olivaceous brown ; vertex, collar and 

 posterior portion of metathorax lighter in colour than patagia and thorax ; 

 antennae with small tuft of whitish hairs at base. Basal half of primaries 

 much darker in colour than remainder of wing. This darker colour is 

 sharply defined outwardly by a still deeper shade proceeding from middle 

 of costa to lower angle of cell, thence to middle of inner margin, an angle 

 slightly greater than 90° being thus formed at junction of veins M3 and Cu. 

 The t. p. line is faintly discernible as a geminate line, composed of a 

 series of lunules, arising on costa at three-quarters of the distance from 

 base to apex, and strongly outcurved to vein M3, thence incurved to vein 

 Cuj, approaching the dark median shade, with which it runs parallel to 

 inner margin. Outer margin shaded with darker olive ; veins scaled with 

 black at outer extremities. Secondaries smoky, darker along outer margin. 

 Underneath light ochreous, slightly darker in cell on primaries, otherwise 

 witliout markings. 



Expanse, 34 mm.

Euxoa xasta, n. sp. 



Palpi yellowish-gray, upturned ; front protruding, gray, mingled at 

 vertex with black ; collar, thorax and patagia gray, with darker shading, 

 the former with a black transverse band, abdomen lighter.
