the genera Plagiosella Hmpsn., and Camptockilus Hmpsn., with which Protero- 

 zeujris agrees in the stalking of veins 7 and 8, it is readil.v separated by the 

 pectinated antennae : while the neuration and shape of wings equally distinguish 

 it from Oxycophina Warn, which has likewise pectinated antennae. 



Tridesmodes gen. nov. 



Foreicings : narrow and elongate ; costa bulged at base, insinuate in middle ; 

 apex produced, blunt ; hindmargin obliquely curved, slightly indented below apex. 



Hindwings : triangular ; the apex much produced ; hindmargin straight ; inner 

 margin short. 



Antennae simple, lamellate ; palpi slender, porrect, ascending. 



Xeuration : forewings ; vein 5 close to vein 4 ; 7, 8, 9, stalked from before 

 upper angle of cell ; 10 closely approximated to 9 ; otherwise like Siculodes. 



Type : Tridesmodes ramiculata sp. nov. 



7. Tridesmodes ramiculata sji. nov. 



Forewings: white, semihyaline, crossed by numerous fine brown branching 

 lines, with still finer transverse brown striae between them : two in the middle 

 forming a brownish triangular mark on costa and inner margin ; the outermost 

 line excnrved towards hindmargin ; marginal line brown : fringe white, tipped 

 with brown. 



Hindwings : similar ; the veins marked with brown. 



Underside like upper. Head, thorax, and abdomen white. 



Expanse of vrings : 19 mm. 



One S from Masiudi, January 1898 (Dr. Ansorge). 



Superficially much resembling a small Siculodes. 



Fajiilv GEOMETRIDAE. 



Subfamily GEOMETRINAE. 



8. AcoUesis umbrata sp. nov. 



Forewings : whitish green, darker towards hindmargin ; a small black cell-spot ; 

 an oblique broadish white line from costa shortly before apex to two-thirds of inner 

 margin, inwardly difi'usely edged with darker green. 



Hindwings : similar, the line slightly sinuous. 



Underside whitish, without markings. Head, tliorax, and abdomen all wliitish 

 green. 



Expanse of wings : 32 mm. 



One ? from Wakibara, Unyoro, July 1897 (Dr. Ansorge). 



Differs from A. frai.ididenta Warr., from the Transvaal, in having the face, legs, 

 and palpi whitish instead of red ; and the line of forewings starting from near apex, 

 as in Collcsis mimica. It agrees with /raudtdcnf a in neuration, except that vein In 

 approximates only to vein 11 without anastomosing with it. 



9. Antharmostes mesoleuca ub. semimarginata nov. 

 Diflfers from the type-form in having an irregularly edged dark brown shade 

 along hindmargin from vein fl to anal angle obliterating the white lunules. In the 

 hindwings this shade is narrower, and the lunnle before the tail is pinkish white.
