costal spot, the postmedian indicated (rather more sharply on the 

 hindwing) by short dashes or teeth on the veins. 



Cape, Montague Baths, November, 1902 (W. F. Purcell), type in 

 coll. S. Afr. Mus. ; paratype in coll. L. B. Prout. 



GEN. LARENTIOIDES, gen. nov. 



Face not protubei'aut, with appressed scales. Palpus rather short, 

 moderately stout, closely scaled ; 3rd joint quite short. Tongue 

 present. Antenna in cf simple. Pectus moderately hairy. Thorax 

 not crested. Abdomen in rf moderately slender, not crested, basal 

 cavity without spine ; hindtibia (lost), therefore evidently without 

 hair-pencil. 



Forewing without fovea ; rather narrow, costal margin nearly 

 straight, apex bluntly pointed, termen scarcely waved, gently curved, 

 strongly oblique ; cell one-half, DC 3 incurved ; C free, SC 2 from cell, 

 anastomosing strongly with SC 1 and afterwards with SO 3 ' 4 , forming 

 a double areole, R- from slightly before middle of DC, M 1 separate. 

 Hindwing rather narrow, costa elongate, apex rounded, termen 

 moderately crenulate, tornus nearly square (the extremity rounded 

 off); cell one-half, DC very slightly curved; C closely approximated 

 to SC to beyond middle of cell, then rapidly diverging, SC 2 separate, 

 R 2 wanting, M 1 well separate. 



Type of the genus : Larei/Hnii/f* ruml/ifn/on, sp. nov. 



Akin to the Oriental genus Hirasa Moore, differing in the much 

 narrower, less crenulate wings, the double areole, longer approximation 

 of C of hindwing to SC and secondarily in the non-dilated hindtibia 

 of the c?. 



29. LARENTIOIDES CACOTHEMON, sp. nov. 



c. 33 mm. Face and palpus dark fuscous. Vertex, thorax, and 

 abdomen grey, irrorated with fuscous, which tends to form on each 

 abdominal tergite a pair of veiy vague spots. 



Forewing rather glossy grey, with a slight violaceous tinge and with 

 sparse fuscous and blackish irroratiou ; lines fuscous, not very strong, 

 but blackened with spots or dots on the veins ; autemediau from two- 

 fifths costa to one-fourth hiudmargin, augulated outward in cell and 

 at submediau fold (shallowly W-shaped) ; median well beyond the 

 slightly elongate black cell-mark, about 1 mm. from the postmedian 

 and approximately parallel therewith, apparently diverging at costa, 

 where, however, it is almost obliterated ; postmedian very oblique and 

 sinuous, from beyond five sixths costa, very gently incurved between
