a single sub-apical sensorium ; the sixth about as long as the fifth, its basal area 

 as long as, or a Uttle longer than, the flagellum ; fourth to sixth and apex of the 

 third imbricated ; the fifth and sixth almost annulated. Head with a small blunt 

 median swelHng and shghtly raised on each side at the base of the antennae, with 

 short, rather thick clavate hairs. Proboscis reaching a httle past the base of the 

 first pair of legs, rather thick and dusky at the apex. Wings about as long as the 

 whole body, rounded apically, with ornamentation as in fig. 25 (B). The moderately 

 long legs show no special pecuharities, except that the second pair are far behind 

 the first and very close to the third, and that the tarsi are very dusky and sometimes 

 the apices of the tibiae also ; the latter have small pale hairs. Cornicles small and 

 showing no special ornamentation. The cauda markedly bilobed, each lobe with 

 two long hairs on the apex and three on the outside, arising from prominent tubercles. 

 Anal plate pale, globular at the apex, projecting beyond the cauda and between 

 the lobes, with some long hairs arising from marked tubercles. In balsam the 

 abdominal spots each have a central clear area, from which arises a small tubercle 

 bearing a thick hair expanded at the apex, of various forms ; the black lateral 

 tubercles each carry a thick hair expanding apically. Lengthy 2-2*5 mm. ; wing 

 expanse, 5-5-5 mm.

Apterous viviparous female. — Uniformly ochreous to pale greenish-yellow, covered 

 with dusky tubercles from which arise strong hairs with expanded apices. Eyes 

 red. Antennae with segments one to three yellowish, fourth dusky ochreous, shading 

 to dusky apically, fifth and sixth dusky. Legs ochreous, tarsi dusky. Cornicles 

 short, of same colour as body, with dusky apical ring. Cauda of same colour as 

 body. Head with capitate hairs. Antennae shorter than the body ; the first 

 segment longer and shghtly wider than the second ; the third the longest, with 

 seven to nine oval sensoria, not extending to the apex ; fourth and fifth nearly 

 equal ; the sixth about as long as the fifth, its basal area as long as the flagellum ; 

 fourth and fifth imbricated ; sixth more or less annulated. Proboscis reaching
