shortest), a lanceolate diseal spot much widened posteriorly and a spot in front of each anterior an^Ie 

 of the basal cruciform elevation, black. Abdomen black, the tympanal coverings and posterior segmental 

 margins dull ochraceous. Head beneath, sternum, and legs dull ochraceous; central sulcation and 

 posterior mai'gins to face ; a fascia between eyes and face, some obscure sternal spots, and a spot at base 

 of opercula, lilack ; alKlomen beneath blackish, with the posterior segmental margins ochraceous. 



Tegmina with about the basal half opaque and creamy ochraceous, costal membrane with two fuscous 

 spots, and the following fuscous fascije : — one basal, one oblique, passing through centre of radial area and 

 terminating at apex of lower ulnar area, and a broad, waved, and irregular fascia commencing at apex of 

 radial area and united with the preceding fascia at apes of lower ulnar area ; between the second and third 

 fasciaj are some small fuscous spots and a semiiiyaline spot near end of radial area, and a similar spot in 

 lower apical area, remainder of tegmina hyaline, with a broad subapical fuscous fascia extending to apex of 

 third ulnar area, an apical fuscous spot and some irregular small fuscous spots on the apices of longitudinal 

 veins to apical areas. Wings dark fuscous, with the outer margins pale hyaline. 



The opercula are pale fuscous, with their outer margins ochraceous, overlapping at centre, outwardly 

 convex, but somewhat oblique at their lateral margins ; the face is considerably compressed, with the 

 central sulcation broad and somewhat deep.

Hab. — China (coll. Sign.) ; Shantung (coll. Dist.) ; Shanghai (Fortune — Brit. Mus.) ; Chusan (Calc. 

 Mus.). Jap.\n (Bligh — Brit. Mus. ; Lewis — coll. Dist.) ; Yokohama (Genoa Mus.). 



This species appears to be quite confined to China and Japan, Mr. Butler has described, 

 under the name of P. fuscangulis, a specimen which seems to be but a slight variety of 

 r. hicmpfcri, and he has given it the habitat of " Sarawak (Wallace)." I think it more than 

 probable that a mistake has been made with this habitat, and I have refi-ained from adding it 

 to the localities given above.

 the inner margin of the eyes, and a short fascia between the ocelli and the eyes, black; pronotum with a 

 rounded black linear fascia behind the eyes and a somewhat triangular spot on inner edge of posterior
