2. LEPTIS 277 



taken by Colonel Yerbury at Tarrington on August 18, 1902, the thorax has 

 one or two pale hairs near the scutellum, and the scutellum is more distinctly 

 translucent luteous except for a large almost semicircular basal middle 

 black spot ; abdomen still more luteous, the basal segment being dark 

 brownish orange, the second, third, and fourth segments with the dorsal 

 black diamonds I'eaching neither fore nor hind margin of each segment, 

 and the one on the fourth segment spreading out widely to the black side- 

 margins, fifth segment black with a rather narrow orange hindmargin which 

 does not extend to the sides ; belly with a dark brownish orange hue on the 

 three or four basal segments and with the hindmargins of segments and the 

 sidemarginal hems conspicuously whitish yellow. 



Legs in the darkest specimens obscure yellowish brown with all the 

 femora and tarsi blackish, but the anterior femora with a slight brownish 

 tinge and the tip of the anterior and the base of the hind femora ochreous 

 for an indefinite distance ; hind tibiae darkened towards the tip ; coxai and 

 trochanters dusted grey, and all the coxai with greyish yellow pubescence in 

 which there are no black hairs on the front pair but several bristly black 

 ones on the posterior pairs at the tip in front. In the next stage the femora 

 are not quite so much blackened, as the anterior femora and the underside 

 and basal half of the hind pair are wholly brownish ochreous, while the 

 front coxae are slightly reddish on their outside. In the next stage the legs 

 are yellowish brown, but the tibiae rather more orange with the hind pair 

 slightly darkened towards the tip ; coxai and trochanters blackish brown 

 with a slight grey tinge caused by dust and with rusty brown pubescence, 

 and the junction of the joints more luteous. In another specimen the basal 

 two-thirds of the hind femora and tibiae are more clearly orange and the apical 

 third more distinctly blackish. In a Tarrington sjiecimen the legs are more 

 luteous, but blackened on the underside of the basal three-fifths of the front 

 femora, and the broad blackish brown tip of the hind femora is extended back 

 towards the base on the underside, the front coxee have rather more lurid 

 orange hues and greyish yellow pubescence, and the posterior coxae have only 

 traces of black hairs at the tip in front. Spurs blackish orange to rather 

 clear dark orange; " touch-hairs " beneath the front tarsi neither numerous 

 nor conspicuous. Pulvilli and claws dark brown. 



Wings rather pale brownish yellow with the fore part fi'om the base to the 

 end of the marginal cell tinged darker or lighter, and the basal part of the 

 subcostal and postical veins almost orange ; alulae with a dark marginal line ; 

 sometimes the wings have a more yellowish hue, and sometimes the long 

 narrow stigma is rather deeper yellow and by no means touching the radial 

 vein. Squamae darkened yellowish grey or sometimes almost all orange. 



9 , Not unlike the male except for the frons and ovipositor. Frons orange 

 brown, with a grey tinge at the sides on the upper part, but lighter 

 grey just above the antennae ; ocellar space more or less darkened ; face 

 with a slightly browner tinge than in L. tringaria ; pubescence on the eye- 

 margins separated by a slight gap from the longer pubescence on the jowls. 

 Eyes in life dark green. 



Thorax orange brown with rather vague light brown stripes ; the humeri 

 and connecting lines obscurely dark orange, but the sides of the disc, the 

 postalar calli, and the greater part of the pleurae hardly at all orange, 

 though the prothorax and metapleurae may be slightly tinged, but the rest of 

 the pleurae light ashy grey with a faint yellowish tinge ; pubescence all black, 

 Scutellum with an extensive blackened reflection about the base, and with 

 wholly black pubescence. 



Abdomen in the darkest form brownish black with obscurely brown hind- 

 margins and with distinct orange hems to the segments of the ovipositor ; 

 but in the next form with sharply defined narrow orange hindmargins to 

 all the segments ; while in the next form the two basal segments are 

 more or less chestnut brown or brownish orange except on the blackish 

 middle part, and the third and fourth segments like the previous two but 

 less distinctly brownish, and the fifth and sixth segments usually with a greyish 

 tinge on a blackish or brownish ground colour ; in pale specimens the tip
