itostriim and palpi dark brown. Antenna? short ; scapal 

 segments dark brown ; flagellar segments small and thin, 

 pale brownish yellow ; verticils long. Head dark brown. 



Pronotum and mesonotum dark brown, the prsescutum 

 with four 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 coxae 

 obscure yellow, the bases indistinctly infuscated, especially 

 the fore and middle coxae ; trochanters pale brownish yellow ; 

 femora yellow, the tips broadly dark brown ; tibiae similar, 

 the tips narrowly 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 with 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-pattern appears as about four ill- 

 defined cross-bands, those before the cord paler and con- 

 tinent in cells Cu and Is/ A ; the band at the cord is 

 broadest and darker brown, extending from before the end 

 of Sc ± to beyond the end of R x , including the bases of cells 

 R 2 and R z ; in the vicinity of cell 1st M 2 the band is pale 

 brown with nearly hyaline areas near the veins ; this third 

 band completely traverses the wing, ending at the tips of 

 veins Cu 2 and 1*/ 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 2 and R 3 , paler in the other cells, including 

 about the outer'half of cells R z and R 5 , all of M x , the outer 

 three-quarters of 2nd Af 2 and the tips of M 3 and Cw x ; a 

 white spot near the end of cell R 2 separating the brown 

 blotches at the ends of veins R 2 and R z ; series of a few 

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

 2nd A, along tin 1 anal veins on their outer ends and near the 

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

 dots, veins dull yellow, brown in the darkened areas. 

 Venation : Sc long', Scj ending about opposite mid-length 

 ol R 2+3 , Sc 2 at the tip of Sc x ; Rs long ; R 2+3 rather shorter 

 than cell 1st M 2 ; r on R v about twice its length before the 

 tip, and on R 2 about twice its length beyond the fork of 

 M 8+3 ; inner ends of cells R z , R 5 , and 1st M 2 almost in 

 alignment ; cell M x deep, nearly twice as long as its petiole ;
