NKW SPKCIRS OF GEOMKTRID^, FROM FORMOSA. 295 



Walk. ; an obscure, slightly curved median shade crossing the cell- 

 spot, which is rather large and oval, but not pale-centred ; post- 

 median line from two-thirds costa, nearly parallel with termen, 

 slightly incurved between m^ and sm"-^, lunulate-dentate, the teeth 

 pointing distad and tliickened ; subterminal line pale, ill-detined, 

 interruptedly lunulate, the lunules filled in proximally with fuscous, 

 those on either side of iM^ the largest and whitish ; terminal lines 

 consisting of a series of black crescentic dashes, well separated by 

 the veins. Hind wing with the median shade becoming antemedian, 

 passing well proximally to the cell-spot, which is somewhat smaller 

 than in fore wing ; postmedian, subterminal and terminal lines as in 

 fore wing. Under side similarly coloured, the fuscous irroration 

 somewhat more irregular, denser in the entire distal area. Fore wing 

 with antemedian line obsolete, median shade weak, cell-spot as above, 

 postmedian thick, diffuse, accompanied distally by an ill-defined pale 

 shade, which thickens on inner margin ; subterminal line almost 

 obliterated, excepting a rather large pale spot anterior to, and a small 

 one posterior to m^ Hind wing similar, the pale dentate postmedian 

 shade somewhat better defined. 



Near Baringa, Lulongo River, Congo, long. 21° E. (Rev. 

 E. Cartwi'ight). Type in coll. L. B. Prout, kindly presented by 

 Mr. G. R. Baldock.' 



Upper side somewhat as in Ectrojns dclosaria, Walk. ( = 

 crassa, Warr.), colour brighter brown, discal spots not ocellated, 

 build somewhat more robust ; under side quite different from 

 that species. Venation agreeing — sci-2 of fore wing long-stalked, 

 arising from cell and not separating till well distad to the 

 separation of sc" from sc3-4.

(Continued from p. 272.) 



Boarmia griseoviridata, sp. n. 



$ . Fore wings greenish grey, finely powdered with blackish ; 

 antemedial line blackish, slender, indistinct ; postmedial line blackish, 

 dotted with black on the veins, outwardly edged with paler ; between 

 postmedial line and the black discal spot is an irregular line, black 

 and serrate towards the costa, sinuous and blackish below the cell 

 where it approaches the postmedial ; subterminal line pale, sinuous, 

 marked witli black at apex, between veins four and six and above 

 dorsum ; termen with black dots more or less connected by a slender 

 black line ; fringes brownish. Hind wings agree in colour with fore 

 wings ; discal spot and postmedial line black, the latter indicated by 

 dots on the veins, otherwise indistinct ; subterminal line pale, in- 

 wardly edged with blackish; termen crenulate, dotted with. black 

 between the veins ; fringes brownish. Under side pale brownish.
