with fuscous black and with raised scales in the cell area; between this patch and vei:tA I is a slender streak of f~lscous black; at one-half a patch of cinnamon buff edgedwith fuscous black extends from the costa to the middle of the discocellulars; at twothirdsthere is a poorly defined, double postmedial fascia of cinnamon buff with aconspicuous fuscous black spot between veins Cu2 and A I; terminal area suffusedwith cinnamon buff and a little fuscous black. Hind wing white. Underside white, thecostal area and the veins of the fore wing and the discocellulars of the hind wingscaled with fuscous.Genitalia. Male. Valve bifurcate to one-half, the ventral arm one-half as broad asthe dorsal and tipped with a single spine. Clavus with the dorsal edge serrate. Aedeagustwo-thirds as long as the ventral edge of the valve; vesica with four short cornuti,one at the apex and three at one-half. The sixth and seventh dorsa have two slender,almost parallel rods, which are dilate near the anterior margin of the sixth segment.The sixth and seventh sterna have a pair of similar, but non-dilate rods, whihcconverge and are fused between the sixth and seventh segments and then diverge.Female. Ductus bursae slender and membranous, as long as the bursa copulatrix,which is also membranous and is pyriform with two large signa as figured.Closely related to C. disticta Hampson (1900) from Bhutan and its subspeciesJeucoscopu/a Hampson (1907) from Ceylon, but differing in the absence of brownshading on the distal and anal margins of the hind wing and structurally in the genitaliaof both sexes. In the males of the two subspecies of disticta the valves are bifurcateto two-thirds, the clavus is digitate and the vesica bears one cornutus only,this laying across the apex; in the female of disticta leucoscopula the ductus bursae isspiralled with three folds; the female of d. disticta is not known. C. pura mayeventuallybe shewn to be a subspecies of disticta when the distribution of that species isknown.L1THOSIINAEEilema testaeea Rothschildllema testacea Rothschild, 1912, Novit. zoo!., 19: 221.E. testacea is at present known only from the Solomon Islands, its range extendingfrom Bougainville in the N.W. to Rennell I. in the S. E. In the British- Museum thereare specimens from Treasury I., Bougainville, Rendova, Ysabel and Rennell lslandsand whilst these island samples show little superficial difference, certain differencesa re apparent in the structure of the genitalia of both sexes.Eilema testaeea testacea Rothschild (Figs. 2, 4, 24)Distribution: Treasury I.; Shortland I.; Bougainville I.d ~ 31-32 mm. The nominate race is distingusihed in the male genitalia by the broad,truncate saccus, equal in width to the produced dorsal margin of the valve. Thevesica bears five corn uti. In the female genitalia an apically-rounded projection ari-36
