Type : Idiotephrn curvieena sp. uov. 



Easily distiuguisbed by the abnormal shapu aud ueuration of the hiudwiogs. 

 Perhaps allied to Tepkrina. 



144. Idiotephra curvivena sp. uov. 



Forewings: pale mouse-colour, slightly freckled with darker; inner line very 

 obscnre, at one-fifth, marked by a darker spot ou the median ; outer line at four- 

 fifths, slightly bent on vein 6, then oblique, parallel to hindmargin, slender and 

 marked by largish dark spots on veins ; submai-ginal very faint, pale, aud denticu- 

 late ; marginal spots small, black ; fringe concolorous ; cell-spot large, black. 



Hind icings : with the outer line at two-thirds, hardly curved ; cell-spot very 

 large, black ; hindmargin darker. 



Underside whitish grey, more or less suffused in forewings with darker, in the 

 hindwings with only the hindmargin darker ; lines aud cell-spots obscurely darker ; 

 costa of forewings pale ochreous, spotted with fuscous. Head, thorax, and abdomen 

 like wings ; face and palpi brown. 



Expanse of wings : 33 mm. 



One cJ from liiver Niger, between Akassa and Onitsha (Dr. Cook). 



145. Petrodava olivata insularis snbsp. nov. 



Since describing the type specimens of this species from Dar-es-Salaam, I have 

 seen others agreeing with them in all respects from Barberton and Mikindaui, both 

 on the east coast of Africa. The present form from Madagascar differs from 

 them all in several points, so that it seems necessary to describe it as at least a 

 subspecies. 



cJ. Forewings : not olive-green, but yellow as in the ? of olimUa ; first line 

 scarcely expressed ; middle liue oblique, not vertical ; marginal brown area with 

 three darker chestnut blotches, touching the third line, at costa, beyond cell, aud at 

 anal angle ; the costal blotch followed by a small yellow patch. 



Hindwings : as in the type, both above and below. 



Underside of forewings with no yellow patch in middle, and at ape.x of 

 hindmargin only the costa remaining yellow. Vertex, thorax, and abdomen 

 yellow. 



Expanse of wings : 34 mm. only. 



One (S from Antanambe, Antongil Bay, Bladagascar, March and April 1897 

 (Mocquerys). 



141). Tephrina (?) convergens. 



Forewings : pale brown, dusted and suffused with darker brown ; the lines 

 dark brown, thick, with slight lustrous edging externally ; first from two-fifths of 

 costa to one-third of inner margin, angled in cell; second from three-fourths 

 of costa to beyond middle of inner margin, acutely angled close to hindmargin ; 

 submargiual at seven-eighths, angled in the hindmargin ; a subcostal diffuse brown 

 streak, through the angles of all the lines ; fringe brown, with two dark lirown 

 lines, one at base, the other in the middle. 



Hindwings : witli the two onter lines only, the first central, the other half-way 

 between it and hindmargin, parallel to each other. 



Underside yellow, slightly striated with brown ; forewing with a short brown
