P. pulchra, sp.nov. Fusca, griseo et rufo-brunneo maculata ;

 hemelytris albidis fusco maculatis ; capitis et prothoracis parte 

 posteriori, et hcutello to to, Isete rufo-brunneis ; pronoLo cana- 

 liculato, postice elevato vix tuberculato. ^ Long. 5^ mm. 



This is an extremely pretty species but very difficult to describe 

 owing to the diversity of its colours. The underside is of a rather 

 fuscous colour with the margins of the abdominal segments paler. 

 The head is of an obscure fuscous colour shading off behind into 

 bright red-brown ; the front half of the thorax is quite blackish, 

 the hinder half bright red-brown ; the antennje are whitish-fuscous 

 with obscure fuscous rings ; the legs are almost white with rings 

 nearly black in colour. The basal half of the hemelytra is pale 

 fuscous mottled with darker shades of the same colour ; the apical 

 half of a clear snowy white tint, mottled with fuscous in such 

 manner that there is a sti'ongly angulated transverse broad white 

 fascia about the middle of the hemelytron, followed by a mottled 

 space about double as broad ; beyond this is another transverse 

 white fascia which is broad on the two opposite margins and 

 irregularly contracted (almost to disappearance) in the middle ; 

 and again beyond this fascia the apex of the hemelytron is much 

 mottled with fuscous. The thorax is peculiarly shaped, the plane 

 of its upper surface being inclined backward and upward from 

 the horizontal ; a corresponding (but reversed) formation of the 

 scutellum compensates for this peculiarity of the thorax, and 

 brings the base of the hind body into about the same plane as tlie 

 head. The thorax has a distinct longitudinal channel. Its hind 

 margin is peculiar and difficult to describe ; it is not tuberculated 

 but appears to be strongly trisinuate, the external portions of this 

 sinuation in some aspects looking like small tubercles. This 

 sinuation is of the extreme hind margin, — almost on the hinder 

 face above the scutellum, — so that when looked at from the level 

 of the head and in front it is hidden, and the thorax appears 

 truncate behind.
