Genus Toxorhynchites. 143 



scales are larger, longer, and spatulate-shaped. (In fresh 

 specimens the colour is said to be like a green bottle-fly.) 



If the thorax is examined through a lens, the central part 

 looks dark coppery-brown to purple, while the sides, when the 

 light strikes at an angle, show metallic green — in other lights the 

 scales appear bluish-green or dark coppery-red ; at the anterior 

 margin of the mesonotum is a band of scales which appear violet, 

 rose-purple or purple, according to the light, and below this a 

 triangular patch of silvery scales immediately behind the 

 prothoracic lobes, and over the roots of the wings a patch of 

 peacock-blue scales and a row of short, stout black bristles. 



Scutellum densely clothed with broad, long Hat scales, which 

 on the lateral lobes are of peacock-blue or metallic green, 

 according to the light, and on the central lobe of a dark green 

 fringed with lighter green posteriorly. 



Scutella bristles short, dark brown. Metanotum, dark brown. 



Wings brown in colour ; the costa and first longitudinal vein 

 clad with broad, flat scales, which are peacock-blue, golden green ; 

 and purple, according to the light ; the position of the cross- 

 veins, the size of the fork-cells and the scaling of the other veins 

 is that of a typical Toxorhynchites. Legs with the coxae 

 yellowish, mid and hind clad with creamy scales on their outer 

 face ; fore legs with the upper surface of the femora clad with 

 rose-purple scales ; at the extreme apex is a tuft of long spindle- 

 shaped scales, which are white or peacock-blue ; just behind these 

 are black spines placed in a semicircle ; the whole of the under 

 surface is covered with bright golden scales ; tibiae entirely 

 covered with purple scales ■ a short distance from the base of the 

 first tarsal is a ring of creamy-yellow scales ; the fourth and 

 iifth tarsals mostly covered with creamy scales, the rest of the 

 tarsal segments with purple scales ; mid legs, femora and tibia 

 as in the fore legs; the basal half of first tarsal with 

 creamy scales, apical half purple scaled ; all the tarsal segments 

 creamy scaled. Hind legs golden at the base and on the under- 

 side, purple above ; scales at apex similar as in the other legs • 

 tibia purple scaled ; first tarsal purple scaled, except for a broad 

 ring of creamy scales a little beyond its base ; second and third 

 tarsal segments purple scaled ; fourth and fifth creamy scaled • 

 ungues equal and simple on all the legs. Pleurae dark brown, 

 for the most part covered with silvery grey scales. Abdomen 

 with the dorsum of the first segment covered with peacock-blue 

 scales, in some lights a dark green ; the other segments covered
