Subfamily SEMIOTHLSINAE. 

 20. Gonodela mundipennis sp. dov. 



Forewiiiys : pale grey with very slight fawn-colonred tinge, and speckled finely 

 with blackisji ; the marginal space beyond third line fawn-colonr : lines very 

 obscure ; first curved, from before one-third of costa to one-fifth of inner margin ; 

 median from a little before middle of costa to before middle of inner margin, slightly 

 outcnrved ronml the distinct large black cell-spot ; outer line from three-fourths of 

 costa to two-thirds of inner margin, very indistinct below costa and aiijiearing simply 

 curved along the course of the darker outer line of the underside which shows 

 through from beneath, but really angled, as usual, on vein 6 ; no trace of dark 

 marginal line or spots ; fringe concolorous, with a pale basal line and finely paler 

 middle line. 



Ilindwings : similar ; median line slightly marked from inner margin to the 

 black cell-spot ; small marginal black dots between the veins. 



Underside with the basal two-thirds whitish striated with dark ; marginal 

 third rufous fawn-colour, edged internally by a crennlate dark brown line, and with 

 traces of a snbmarginal line, most distinct in the lower half of wing, where it is 

 preceded by a dark cloud and followed by a paler patch ; in the hind wings the outer 

 edge of the submarginal shade is evenly undulating throughout ; fringe of hindwiugs 

 whitish. Face and palpi brownish above, paler beneath ; collar brownish, vertex 

 pale ; thorax and abdomen like wings. 



Expanse of wings : 40 mm. 



1 ? from the Ualwella River, Angola, June 1898 (Tenrice). 



Crassilembaria Mab. from Madagascar must be somewhat like this species in 

 appearance, but the expanse of that insect is given as 27 mm. only. 



30. Semiothisa majestica sp. nov. 



c?. Forewings : very pale ochreous, with slightly darker but inconspicuous 

 dusting : the lines jiale brown ; first from one-fifth of costa to one-fourth of inner 

 margin, obtusely angled just above median vein ; second from middle of costa to 

 middle of inner margin, bent outwards and bluntly curved beyond cell ; cell-mark 

 linear, brown, preceded by a straight brown line from costa showing through from 

 the underside ; outer line from four-fifths of costa, below which it is curved, then 

 straight to three-fourths of inner margin ; marginal area beyond outer line slightly 

 darker, especially close to the line, which is followed on costa by a short brown 

 streak ; a dark brown marginal line along the excision from vein 7 to 4, where the 

 ochreous fringe also is dark brown. 



Ilimltvings : with nearly straight antemedian line and black cell-spot ; the 

 outer line obscurely double. Head, thorax, and abdomen concolorous with wings. 

 Underside of wings warmer ochreous, with all the markings distinctly brown, except 

 the inner and median lines of forewiugs, which are very faint, 



? greyer ochreous, with strongly marked l)rown striations ; all the lines 

 darker ; a fine ))rown marginal line in both wings. 



Expanse of wings : <S 40 mm. ; ? 44 mm. 



A pair from Longa lliver, Angola, November IS'JIJ (Peurice). The difference 

 in colour between the sexes, which is very noticeable in these two specimens, is 

 probably not constant.
