U2 



deep as wide, and when seen from the front about as wid- as deep ; 

 eyes in death slightly greenish or purplish deep black, with three 

 narrow but entire or not entire purplish transverse bands (narrower than 

 those in the former species), of which the middle band runs straight 

 from the top of the frontal triangle to the middle of the back of the 

 eye, while the upper and lower bands are rather broad, equidistant from 

 the middle one but very inconspicuously divergent outwards and on 

 the outer quarter sharply converging until they almost touch the middle 

 line, these three bands sometimes not quite sharply defined or not 

 quite conspicuous at the hind end. 



Thorax black, moderately dusted with grey or brownish grey, 

 and moderately shining, short and stout, somewhat roundish, with three 

 rather indistinct grey or brownish grey median stripes of which the 

 middle one is very narrow and more inconspicuous and does not reach 

 the posterior margin, while the others are broader, rather distinct, ex- 

 tending from the front part to the hind margin, and are slightly 

 approached from one another after the suture and indistinctly fused 

 together leaving a faint blackish triangle at the middle of the hind 

 border, there is other stripe on the side of the disc, which is very 

 broad though not well-defined and tends to connect with the outer 

 median stripe on the front part and about the suture ; these stripes are 

 light yellowish grey or somewhat ashy grey ; pubescence on the disc 

 mostly long and erect, black, but on the greyish stripes there is an 

 abundant thin, short and despressed, yellowish white pubescence which 

 grows up considerably longer and tuft-like above the wing-bases ; humeri 

 sometimes brownish grey, clothed with long somewhat shaggy yellow- 

 ish white hairs ; praealar calli somewhat indistinct greyish black or 

 sometimes greyish red-brown, with a distinct tuft of long shaggy black 

 hairs and with a few shorter yellowish pubescence interspaced above ; 

 postalar calli slightly brownish yellow or sometimes greyish red-brown, 

 covered with rather sparse long black hairs above but about the lower 

 half with rather dense Ions vellowish hairs similar to those above the
