Kostriim and palpi dark brown. Aiitenna3 short ; scapal 

 segments dark brown ; flagellar segments small and tliin, 

 pale brownish yellow ; vertieils long. Head dark brown. 



Pronotuiu and mesonutum dark brown, the praiscutum 

 with lour narrow^ dark brown stripes^ the intermediate pair 

 separated from one another by a pale grey line. Pleura 

 dark brown, discoloured in the unique type. Halteres light 

 yellow, the knobs scarcely darker. Legs with the coxte 

 obscure yellow, the bases indistinctly infuscated, especially 

 the fore and middle coxse ; trochanters pale brownish yellow ; 

 fetuora yellow^, the tips broadly dark brown ; tibise similar, 

 the tips narro\Yly dark brown ; first two tarsal segments 

 yellow, the tips very narrowly brown ; remaining tarsal 

 segments brown ; legs moderately long and stout, the seg- 

 ments clothed witli an abundant, delicate, nearly erect 

 pubescence. Wings whitish subhyaline with a heavy brown 

 pattern, the wing-base indistinctly yellowish ; the dark 

 markings are arranged as follows : a series of about twelve 

 to fifteen spots and blotches in the costal and subcostal 

 cells ; the major wing-uatteru appears as about four ill- 

 detined cross-bauds, those before the cord paler and con- 

 fluent in cells Ca and ist A ; the band at the cord is 

 broadest and darker brown, extending from before the end 

 of iSci to beyond ttie end of i?i, including tlie bases of cells 

 R2 and R^ ; in the vicinity of cell \st M^ the band is pale 

 brown with nearly hyaline areas near the veins ; this third 

 band completely traverses the wing, ending at the tips of 

 vems C'uj and ist A as very pale blotches ; this band is 

 connected in cell M with the paler second band which 

 occupies the level of the origin of Rs ; the fourth band 

 occupies the wing-apex, appearing as two dark areas at the 

 ends of veins R^ and R^, paler in the other cells, including 

 about the outer half of cells R^ and Rr„ all of Mi, the outer 

 three-quarters of 'Ziul M^ and the tips of M^ and Cui ; a 

 white spot near the end of cell R2 separating the brown 

 blotches at the ends of veins R.^ and R^ ; series of a few 

 pale brown spots along the wing-margin iii cells 1st A and 

 2nd A, along the anal veins on their outer ends and neai- the 

 base of cell Cu ; the white interspaces are free from brown 

 dots ; veins dull yellow, brown m the darkened areas. 

 Venation : iSc long, Scy ending about opposite mid-length 

 of 7^2+3, -^'^2 at the tip of Sc\ ; Rs long ; ^2+3 rather shorter 

 than cell 1st M^; r on R^ about twice its length before the 

 tip, and on R^ about twice its length beyond the fork of 

 R^^i ; inner ends of cells R^, R^, and \st Mo almost in 

 alignment ; cell My deep, nearly twice as long as its petiole;
