spurs show the close affinity of this .sj)ecies with tlie Jioresaria group. Perhaps it 

 is a form of laticostata Warr. (^Noc. Zool. xiii. p. 84), very slightly larger, bend 

 in teriuen of hiiidwiiig rather more feeble, colour yellower green, fringe brighter 

 golden, terminal line less nearly continuous, costal area of forewiug beneath more 

 differentiated. 



This group and especially manjinepimcta Warr. {Noe. Zool. x. p. 350, ? = 

 Oenospila peristicta Prout, Gen. Ins. 129. p. 162, S) and laticostata Warr. seem to 

 connect the genus Oenospila Swinh. with Prasinoci/nm, and it is to be feared (as I 

 already hinted, loc. cit.) that the latter large and less specialised genus will 

 ultimately have to be merged in the small and specialised Oenospila, which bears 

 the chronologically antecedent name. 



87. Prasinocyma discoprivata spec. nov. 



d ? , 36-4U mm. Face bright green. Palpns with third joint moderately 

 elongate ; green, white beneath. Vertex and autennal shaft white ; occiput green, 

 separated from the white vertex by a very narrow yellow band or line. Thorax 

 and abdomen green above, white beneath ; extremity of abdomen also white above ; 

 a yellow dorsal line. Legs mostly white, forecoxa green in front, foreleg smokv 

 on upper and outer side. 



Wings apple-green, shaped nearly as in discata Warr. (Noo. Zool. xiii. p. 83), 

 the bend in the termen of hindwing inappreciable, the termen not even so convex 



as in most of the allies. Foretoing with costa yellow at base, otherwise the 



extreme edge pure white, narrowly separated from the ground-colour by yellow 

 slightly mixed with reddish brown ; a reddish brown spot at apex ; lines very 

 faintly pale, little noticeable ; Krst from about one-fourth costa, oblique to 

 posterior margin beyond one-third, slightly outbent behind M and then inbent, bnt 

 much less irregular than in discata ; second j)laced as in discata bnt rather more 

 shallowly dentate ; a very small blackisli cell-spot touching distal side of iJt'^, a 

 faint red mark on the proximal curve of DC' ; a yellow terminal line dusted with 

 red-brown proximally and with minute red-brown dots at vein-ends ; fringe pale 



yellow. Hindwing similar except costal edge, the black cell-spot nut accom- 



l)auied by a red mark. 



Underside whitish green, costal part of Ibrewing brighter green, including cell 

 but narrowing to apex ; costal edge of forcwing yellow at base, then white, a 

 red-brown line (thickest towards base) separating this edging from the green 

 colour ; the costal extremity of veins C and SC'"^ also tinged with red-brown and 

 a red-brown spot at apex.

Together with this form were received \ H whose appearance is rendered 

 .strikingly different by the i)resence of a large deep puride-fnscous discal blotch on 

 the hindwing, as large as in the least extreme discata but unicolorous. The form 

 may be distinguished as ali. semidiscata ab. nov. 



This species evidently belongs to the group which seems transitional towards 

 (iiganlothea or jierhajis towards (_'hri/.iochloroni(i ; ISC' of forewiug free, or anasto- 

 mosing slightly with C, DC'' deejily incurved, ]{■' of hindwing from much above 

 middle of DC, W and It' both rather shortly stalked; hindleg with strong hair- 

 pencil, all spurs develojicil.
