142 Novitates Zoologicae XXXV. 1929. NEW PALAEARCTIC GEOMETRIDAE. By LOUIS B. PROUT. Subfam. STERRHINAE 1. Sterrha aversata indeviata 8nbsp.n. cJ, 29-30 mm. Ground-colour as in the palest forms of a. aversata Linn. -Forewing with median line anteriorly straight, almost as oblique as termen, crossing the cell-dot ; postmedian much less bent than in a. aversata ; no band between median and postmedian. Hindwing with median line straight, or almost so, considerably proximal to the cell-dot. In addition, the termen of both wings is slightly more sinuous than in most aversata. Algeria: Hammam Rirha, 19-23 June 1916 (V. Faroult), type in coll. Tring Mus. Tunis : Ain Draham, 6-19 August 1911 (V. Faroult), 2 ^6 m the same collection. Subfam. LARENTHNAE 2. Ecliptopera mactata placata subsp.n. (J?. Distinguished from m. mactata Feld. (1875, Japan) as follows: Forewing with the antemedian white line bilobed rather than biangulate, the projections being shorter and blunter, usually well separated from the median ; postmedian with the central prong looking broader, being as near the termen behind M 1 as before it, faintly incurved at M 1 ; subterminal formed of con-spicuous white spots. Hindiving with the postmedian more proximal anteriorly, more direct from costa to M 2 , sharply outbent to fold. China, very widely distributed, the type ^ from Ningpo, July 1886 (native collector) in coll. Tring Mus., together with a specimen from " West China." I have it from Wenchow and Kiukiang, the British Museum from Moupin, the Hill Museum from Hunan, Central China, 4 examples. 3. Earophila semna sp.n. $, 42 mm. Best comparable with Coenotephria (?) malvata (Ramb.), but on the present tentative system of classification an Earophila (vide UAmat. Papil. iii. 222, No. 16, where — as is shown by the context — " avant " is a misprint for " apres "). Wings even broader than in the species named, the forewing having the costal margin more shouldered at the base, the hindwing the termen slightly more convex. Face without cone. Palpus nearly 1J. Antenna pubescent. Head and body concolorous with wings. Forewing with termen markedly crenulate, except between apex and R 1 ; glossy russet, somewhat dulled by dark dots on the veins, especially in the areas on either side of the central ; basal area slightly more tawny ; apical dash short and weak, hardly more oblique than termen ; cell-dot enlarged into a small spot, indistinctly ocellated ; lines grey (dark gull-grey to slate-grey), with a tinge of blue ; subbasal as in malvata or slightly more excurved ; ante-median rather indistinct, about as in malvata ; rounded median spots best developed posteriorly ; postmedian proximally very finely white-edged from
