98 ZOOLOGICAL RESULTS OF THE EUWENZOEI EXPEDITION. 



distinguished, inter alia, by its narrower and more elongate shape, dusky hind borders to 

 the abdominal segments, infuscated wings, and the absence of an appendix to t!ie bend 

 of the fourth longitudinal vein. Bexia lur/ens Wied. (Auss. zw. Ins. ii. 1830, p. 374), 

 the type of which is stated to be from the Cape of Good Hope, was perhaps wrongly 

 assigned by its author to the present genus ; but in any event I), inappencliculata must 

 be readily distinguishable from it, since, according to the original description, the 

 abdomen in Wiedemann's species is shimmering grey and black, with an almost 

 chequered appearance. A $ Bexia from Natal in the Museum collection, belonging 

 in all probability to an undescribed species, has the usual appendix to the fourth 

 longitudinal vein.

6 . — Length (1 specimen) 12 mm. ; width of head 3 mm. ; width of front at vertex 

 0'8 mm. ; greatest width of abdomen just over 3 mm. ; length of wing 9'5 mm. 



Olivaceous, hody rather narroiv and elongate ; dorsum of thorax with three fairlij 

 hroad, dark, longitudinal stripes; abdomen tvith shimmering patches of usual type, anal 

 segments shining black ; all hair and bristles on body and legs black ; tvings with a 

 brownish tinge, and each iving with a large, circular, clove-brown spot surroiinding small 

 transverse vein, and three other somewhat lighter clove-broivn markings. 



Head black, front and face clothed with pale yellowish pollen, jowls and occiput 

 with greyish pollen ; when viewed in profile, a conspicuous, quadrate, dark patch next 

 eye on each side, on a level with base of antennae ; frontal stripe black ; upper part of 

 sides of face with a descending row of fine hairs, lower part of sides of face with a 

 row of four or five relatively long and stout bristles, uppermost bristle but one being 

 particularly long; 'palpi and antennce (including arista) clove-brown, third joint of 

 antenna nearly three times as long as second. Thorax: four post-sutural dorso-central 

 bristles, of which second, counting from front, is very small m case of type; dorsum 

 in type damaged by exudation of fluid, median longitudinal stripe apparently olive ; 

 SGutellum olive, with a lighter fleck on each basal angle. Abdomen : second, third, 

 and fourth segments each with a narrow, median, dorsal, sepia-coloured triangle, its 

 base resting on posterior and its apex extending to anterior margin ; when abdomen is 

 viewed from above, each of these triangles appears situated on a shimmering olive-grey 

 patch of irregular outline, while on each side, in case of second and third segments, 

 with its base resting on anterior margin and its posterior angles rounded, is a quadrate 

 shimmering olive-grey patch, hind margin of which is not quite half-way between front 

 and hind margins of segment ; on fourth segment corresponding patches are smaller 

 and more irregular in outline; second, third, and fourth segments each with a pair of 

 median marginal macrocheetfe on dorsum, pair on fourth segment being in centre, and
