African Species of the Getiiis Cluysops. 515 



the scutellum extending to the hind margin, and on each 

 side curving outwards so as to form a black hind border to 

 the segment reaching to the lateral margins ; a small 

 yellowish-grey triangle on the posterior margin, in the 

 middle line, partially divides the blotch into two halves ; 

 second and third segments with a pair of large black or 

 blackish-brown blotches, roughly quadrate in shape, with the 

 posterior inner angles rounded off, and the outer border (at 

 least in the case of the blotches on the second segment) 

 emarginate ; on the second segment the emarginate outer 

 borders of the blotches run out to the basal angles, thus 

 forming, with the corresponding markings on the first 

 segment, an incomplete transverse band ; in the case of the 

 second segment the hinder edge of the blotches is close to 

 the hind margin, in that of the third the drab-grey or buft- 

 coloured hind border is usually a little deeper ; fourth 

 segment with a similar pair of blackish blotches (most 

 distinct when the insect is viewed obliquely from behind), 

 more or less rounded off posteriorly, but not emarginate on 

 the outer side ; fifth, sixth, and seventh segments dark 

 browu, hind borders of fifth and sixth drab-grey, buff, or 

 ochraceous-bufF; upper surface of abdomen, especially poste- 

 riorly, clothed with minute golden hairs, lateral margins 

 of fifth and following segments fringed with longer brownish 

 hair ; blotches on third segment covered with minute black 

 hairs ; venter mouse-grey, clothed with fine golden hair, 

 longer than on dorsum and more erect j hind borders of 

 segments yellowish. Wings : brown area at base including 

 basal fourth to basal sixth of first and second basal cells, the 

 tips of which are included in the transverse band ; second 

 costal cell lighter towards the tip ; stigma large and well- 

 marked, dark browu ; distal margin of transverse band 

 beginning on costal border halfway or two thirds of the 

 distance between end of stigma and level of fork of third 

 vein, and then running obliquely backwards with two promi- 

 nences, one on third vein before it bifurcates, the other in 

 base of second posterior cell ; transverse band terminates in 

 anal cell and does not reach sixth longitudinal vein ; discal 

 cell entirely included in transverse band, but its central 

 portion as well as base of first submarginal cell usually 

 lighter; in the apical blotch the intensiji cations of colour 

 round the ends of the second longitudinal vein and upper branch 

 of the third very conspicuous and characteristic; against a 

 dark background the distal border of the transverse band is 

 seen to have a lighter edging. Halto'es davk brown. Legs : 

 coxce mouse-grey ; last three joints of all tarsi dark brown ;
