99. Psilocerea tarsispina Winr. 



Tliis insect was described iVoin a single S from J'ritish East Africa (Nov. 

 ZooL. Mil. p. 215). That sex does not, as far as I have seen, appear to vary; 

 three examples from near the same locality, sent by Doherty, agree exactly with the 

 type ; with them was a single ? , which differs slightly, as follows. Apex of forewiug 

 produced, falcate ; liindmavgin excised below, and bluntly clbowi'd at middle. Both 

 wings more suffused with flesh-colour, especially along the hindinargins and the 

 fringes; the colouring more uniform, owing to the absence of dark speckles, which 

 are restricted to the hindmargins, and there occur but sparsely; the outer line and 

 the apical markings stronger. Beneath tliere is little difference. The antennae arc 

 simple. 



Expanse of wings : 40 mm. 



The four specimens were taken at the Escarpment, British East Africa, from 

 8e[iteinber to November 1900, at an elevation of between (i.iOO and 9000 ft. 



100. Psilocerea tumida sp. nov. 



Forewings: olive-fawn-colour, browner with a slight violet gloss along himl- 

 margins, and thickly speckled with fuscous and black ; markings like those of 

 tarsi»phm, the outer line edged externally with jjale; area immediately beyond it 

 paler, with traces of olive triangular patches touching outer line. 



Hindwiwja : without first line ; fringes as in forewings, chocolate-brown. 



Underside paler, densely speckled, especially in hindwings. Head, thorax, and 

 abdomen pale fawn-colour ; vertex the same, not white as in tarswpiiia always. 



Expanse of wings : 46 mm. 



One ? from tlie Escarpment, British East Africa, Manli 1901 (W. Doherty). 



The same remark applies here as in the case of P. nigrociimulata. Notwith- 

 standing the vast difference in ground-colour between them both and tarsispina. 

 they may prove to be seasonal forms. Tumida, however, differs in two other points 

 besides coloration : the hindmargin of forewings, instead of being bluntly elbowed 

 at middle, forms there a large tumid projection ; and tlie vertex of head is concolorous 

 with the face, not white. No SS of either of the darker forms appear to have 

 been taken. 



101. Psilocerea turpis sp. nov. 



S. Forewings: dull greyi.sh fawn-colour, finely black-speckled ; all the veins in 

 the marginal area generally finely paler ; first line obscurely darker, from one-fourth 

 of costa to one-third of inner margin, sinuous, marked with black dots on veins; outer 

 line from three-fourths of costa to two-thirds of inner margin, straight ; in some 

 eases fine, dark, and indistinct; in others doulile and marked by pale dots on veins; 

 in one case uninterruptedly wliitisb, with a I'.nc dai-k imjer edge; cell-spot black; 

 fringe concolorous. 



Hindwings : with oidy the postmedian tine and <ell-spot. 



Underside ijuite pale ochreous with fuscous dusting; cell-spots distinct; outer 

 line indicated more or less plainly. Face and jjalpi brownish; fillet whitisli; thorax 

 and abdomen like wings; shaft of antennae white; pectinations dark; abdomen 

 below and at sides, and I lie legs pale ochreous.
