NOVITATES ZOOLOGICAB XXXVII. 1932. 229 NEW GENERA AND SPECIES OF STERRHINAE (FAM. (lEOMETEIDAE). By LOUIS B. PROUT. A S my catalogue of this subfamily in the Lepidopterorum Catalogus is to appear this year, and it is desirable that it .should place the species as nearly as possible in the genera to which they are assigned iii the long-delayed Genera Insectorum revision, it has become urgent to publish a few genera which have hitherto stood in manuscript only. At the same time, there is some danger of a collision with the Sterrhinne in Seitz, at least as regards Vol. XVI, for which the manuscript is completed, but not likely to be published for several months. I have therefore added diagnoses of several species which otherwise would have awaited publication in that work. Metallaxis gen. n. S-Palpus short, terminal joint small. Antenna fasciculate. Hindtibia with a pair of spm-s (type) or spurless ; $ (semipurpurascens Hmpsn.) with four spurs. Forewing with cell rather short, DC usually short, areole double, SC from cell, R^ normal. Hinclwing with termen weakly bent at R^ cell rather short, C normal, SC^-R' shortly stalked, R= central, W separate. Genitalia show in the aborted mappa, etc., a near relationship to RhodoslropMa, whereas Somatina approaches Scopula. Type of the genus : Metallaxis semiusttis (Swinh.)*= Erythrolophus semivstus Swinh. (1894). To the two hitherto known species (the type and " Rhodosirophia " semi-purpurascens Hmpsn., 1896) I add provisionally : 1. Metallaxis teledapa sp. n. S, 18-21 mm. Smaller than the two Indian species, cell of forewmg a Uttle less short, hindwing with abdominal margin relatively longer. Hindtibia with strong pencils, without spurs, tarsus nearly |. Whitish buff, the forewing irregularly (chiefly in posterior part and median area) irrorated with vinaceous cinnamon, the irroration largely confluent. Forewing with dark admixture at base and (more leaden) along a large part of costal margin ; an ill-defined longitudmal line along M and proximal part of M^ ; antemedian line fine, curving outward to near cell-mark, sometimes obsolescent anteriorly ; postmedian fine, excurved ; a rather oblique mark in distal area between the radials and a tornal patch as far as M^ Both wings with a dark terminal line. Underside paler, weakly marked. Madagascar : Diego Suarez, V2 ^ ,^ (G. Melon), type in Mus. Trmg. Pseuderythrolophus gen. n. Palpus with 3rd joint short, especially in the ,^. Antenna of cj bipectinate to beyond middle, with very strong branches. Hindtibia of ^ strongly thickened and tufted, without spms, of $ with 3 spurs. Abdomen rather robust, in £
