TSYCHOPSIS MEYIIICKI, n. sp. 

 BY ROBERT McLACHLAN, F.R.S., &c. ! 



P. Meyricki. 



Allied to P. insolens, McLach. (Journal of Entomology, ii, p. 114, pi. yi, fig. 3), / 

 but smaller and darker. Head yellow, but the anterior swollen portion of tho 

 vertex is blackish-fuscous, which colour continues to below the base of the antenniB 

 on the front ; clothing yellow. Antennse reddish-brown, dingy yellowish towards 

 the base. Pronotum and entire breast yellow, with concolorous hairs. Meso- and 

 mcta-nota suffused with livid grey. Legs yellow ; apex of tibiae, and of the tarsal 

 joints (faintly), marked with fuscescent. Abdomen above livid (or pale leaden) 

 grey, beneath yellowish ; hairs yellow : superior appendages (<?) in the form of two 

 elongate yellow valves, flattened laterally, convergent at base and apex above, fur- 

 nished with very long yellow hairs, sub-obtuse at apex, with an oval callus in tho 

 middle externally ; the margin of the last ventral segment is regular, and internally, 

 seen vcntrally, appear to be two smaller flattened valves, convergent apically, 

 probably representing the inferior appendages, the triangular space between them 

 is blackish. 



Anterior-wings whitish-hyaline, but densely tessellated or freckled with pale 

 grey markings, vaguely arranged in transverse oblique lines ; three or four sub- 

 quadrate spots on the area between the sub-costa and the sector, and others on the 

 inner margin, are darker and more conspicuous : neuration for the most part 

 blackish-fuscous, but with numerous pale spaces ; hairs of neuration mostly yel- 

 lowish, but mixed with blackish, and on the margins the hairs alternate in pale and 

 dark spaces (conspicuous on the costal margin) : two series of gradate nervules, one 

 placed before the middle of the wing, the other extending downwards from the 

 point where the sub-costa and radius become confluent. Posterior-wings with 

 indications of grey freckling and darker spots, but much less conspicuous ; the 

 characteristic large rounded spot at the confluence of sub-costa and radius is pale 

 fuscous. Length of body, 9 — 10 mm. Expanse, 26 — 28 mm. 



Hab. : Mount Kosciusko (New South Wales), 2800 ft., 20th 

 January, 1885. 



I have seven examples before me, apparently all ^ , collected by 

 Mr. E. Meyrick, who says the insect was abundant on rocks, whither 

 it went to avoid the sun and heat. 



P. insolens, McLach., is larger and much paler; the anterior- 

 wings have a tendency to be marked in the same manner, but with 

 ochreous-yellow instead of grey, and in the posterior-wings there is 

 only the large rounded ante-apical spot. Moreover, in P. insolens, 

 and in all the other species, there is a third, sub-marginal, series of 

 gradate nervules in the anterior-wings, continuous with the series of 

 transverse nervules in the costal area ; of this third series I see no 

 trace in P. Meyricki. 



I have said that all my examples of P. Meyricki appear to be (J ; 

 so I judge from the comparatively slender abdomen. If this be so,
